Delivery terms?

At Fuel Tank Shop we take customer service very seriously and pride ourselves on our amazing feedback and delivery record.  The delivery of a tank can be the confusing bit as each manufacturer offer a slightly different service and lead time.  Our Fuel Tank Shop sales team will discuss the various options with you to make this as stress free as possible, but as a guideline here are the general delivery lead times and delivery options available to you as a valued Fuel Tank Shop customer.

Tank Guideline Lead Times:

Standard tank deliveries are "kerbside".  Positioning of your tank will be the responsibility of the customer/installer.

Some deliveries will be made via an Articulated Lorry (Artic).  If your delivery address, access to your delivery address and/or the surrounding roads cannot accept an Articulated Lorry please ensure we are aware of this so that an alternative delivery, if possible, can be sourced.  Off-loading of the tanks may also be required by the customer.  

Please advise us if you are unable to off-load so alternative arrangements, if possible, can be made.


Tank Delivery Options:

TAIL LIFT Delivery: Available at NO EXTRA cost for most tanks up to 2500 litres.

HIAB Delivery: Available at EXTRA cost for steel tanks, Deso and Titan tanks. 

We will make every effort to deliver on the expected delivery date and will communicate with you the information that is given to us by the manufacturer and their haulage company.  We cannot accept any charges or compensation claims arising from late or failed deliveries.  We do not recommend booking engineers or fuel deliveries pending your delivery.

Accessory Guideline Lead Times:

Most accessories will be delivered within 1-3 working days. If you require them quicker, we can on occasions offer a next day service (please contact us to discuss). If the item(s) are out of stock we will advise you of the expected lead time and you will of course have the opportunity to cancel with a full refund.

Nationwide Delivery: We can arrange for all accessory items to be delivered Nationwide, however Scottish Islands, Channel Islands and IOM may incur further postage costs, please enquire for details. We can only deliver tanks to the mainland (not Scottish Islands, Channel Islands and IOM).  We will happily deliver a tank to to a forwarding agent for you.

What are my delivery options?

We offer either a courier delivery or collection (if you would like to collect, please contact us first to make sure the product you are wishing to collect is available). Please Note - Collection is unfortunately not available from our Minehead Offices.

For the majority of our tanks they come with a Free Tail lift delivery (where the tank is lowered off the delivery vehicle), however if a HIAB delivery is required or there is an issue with access, please give us a ring to find out options available and any costs if applicable.

Can i receive a delivery on a weekend?

Sorry, we only deliver on weekdays.

Can I change my delivery address?

This may be possible depending on how far your order has been processed. Please contact us as soon as you can so we can try and avoid any costs already incurred being passed onto you.

Do I need to be in when my order arrives?

It’s always best if you can be at the delivery address for delivery. Not only to check the goods before signing for them but also to avoid any re-delivery charges that may apply.

I have missed my delivery, what do I do now?

For smaller orders delivered by Royal Mail or other courier services, the delivery driver will leave a card at the address with details on how to proceed with collecting from their nearest depot or arranging the re-delivery.

For larger items which are delivered by a pallet service, this may incur an additional delivery charge to re-arrange the service. Please contact our sales team if you need more information on re-arranging a delivery.

Do you offer a next day delivery service and what is the cut off, if this is possible?

Some products are available on a next day service, cut off times vary. Please contact us for more details.

What is meant by 'Estimated lead time' and are they accurate?

Each product has their own specific lead time, which is the time it takes from placing your order until it is delivered to your chosen address. This includes manufacturing and processing times. The lead times can be found on the product page.

We try to update the lead times weekly, however if the lead times changes and you have placed an order, we will contact you as soon as we can.

If you require a product sooner than the lead time advertised, please give the sales team a ring to see if we can accommodate this for you.


Can I finance a tank ?

Yes. We can arrange any diesel dispensing tank to be purchased through finance with our partner Kennet Leasing. Minimum purchase value £1000 and currently B2B only. 
Please contact us for further details and we can arrange for one of the Kennet Leasing finance team to contact you to go through the application process

Oil Tanks


Can you screen an oil tank?

Although Oil tanks are not the most attractive things to have in your garden, we always recommend seeking the advice of your local OFTEC registered liquid fuel tank installer as to the best place to position and how to screen your tank, if needed. The regulations for oil tank installation vary according to which region of the UK or Ireland you live in and there are also other environmental factors that need to be taken into account.  For more information, please check out - OFTEC

Some ways customers have screened their tanks are below, however please check with your local OFTEC installer first.


One of the most common ways to hide an oil tank is to build a false wall around it. Whether you use bricks, stone or fencing, make sure you leave space to get in and around the tank for maintenance and replacement.


Probably the most effective and aesthetic ways to hide an oil tank is to surround it with shrubs, trees, or potted plants that can help to camouflage the tank from view. Make sure you the plants are properly maintained, as they can become a fire hazard if not cared for properly.


Whatever option you choose, your tank will be out of sight – but it should not remain out of mind! Remember to keep on top of oil levels and have your tank regularly inspected by a qualified engineer to prevent any potential problems.


Do I need a bunded tank, and how do I know?

All non-domestic oil storage tanks over 200 litres need to be bunded.

For domestic premises you need to carry out an oil storage risk assessment (this can be obtained from OFTEC - form TI/133D). In brief a Bund is required in domestic situations if...

    • You are storing over 2500 litres.
    • Your tank is near an open drain or loose fitting manhole.
    • Your tank is within 10m of controlled water such as a river, stream etc.
    • Your tank is located where any spillage could travel over hard ground to reach controlled water.
    • Your tank is located within 50m of a borehole, spring or well.
    • Your tank vent is not visible from the fill point. (Such as an extended fill point)
    • Your oil use is for a building other than a single family dwelling.
    • Any other unique hazards to your site.
    • Please refer to The OFTEC home guide to domestic oil storage

What is a Single Skin Tank?

A Single Skin Oil Tank consists of a single container in which fuel is stored. Unlike Bunded Oil Tanks and Bunded Fuel Tanks, Single Skin Oil Tanks incorporate no secondary containment whatsoever and in the event of a spill, a pollution incident will occur.

Single Skin Oil Tanks are not suitable for the storage of fuel at commercial, industrial or institutional premises; or at domestic installations with an installed capacity of over 2,500 litres - unless installed within a suitably bunded area. For all other installations, an Oil Tank Risk Assessment must be undertaken by a competent person prior to installation and in accordance with the requirements of OFTEC Technical Instruction Book 3.

In anticipation of future possible regulations, serious consideration should be given to fitting a Bunded Tank, even where a single skin tank may currently suffice.

What is a Bunded Tank?

A Bunded Oil Tank is simply a tank within a tank. The fuel is stored in the inner tank and the outer tank acts as a failsafe so that in the event of a spillage, excess fuel will collect in the bund. They are a requirement at commercial, industrial and institutional premises.  In some circumstances in domestic situations it is still possible to use a single skin tank (see below).


How close to a boundary can I place an oil storage tank?

If the oil tank has a nominal capacity of less than 3,500 litres, it should not be placed any closer than 760mm to a boundary. This assumes that there are no flue outlets or buildings between the tank and the boundary. Where these distances cannot be achieved, the protection measures noted in OFTEC Technical Instruction Book 3 and British Standard BS5410 must be provided by means of a 30-minute fire resistant wall which extends a minimum of 300mm above and beyond the ends of the oil tank. For oil tanks with a nominal capacity of 3,500 litres or greater please contact your local Building Control Officer or OFTEC.

How close to a flue outlet can I place an oil tank?

Oil tanks with a nominal capacity of less than 3,500 litres should not be placed within 1.8 metres of a flue outlet. Where these distances cannot be achieved, the protection measures noted in OFTEC Technical Instruction Book 3 and British Standard BS5410 must be provided by means of a 30-minute fire resistant wall which extends a minimum of 300mm above and beyond the ends of the tank. For oil tanks with a nominal capacity of 3,500 litres or greater please contact your local Building Control Officer or OFTEC.

How close to a building can I place an oil tank?

Oil tanks with a nominal capacity not exceeding 3,500 litres should not be fitted any closer than 1.8 metres to a non fire-rated (30-minute minimum fire resistance) wall or eaves. Where these clearances cannot be achieved, the measures noted in British Standard BS5410 and OFTEC Technical Instruction Book 3 must be provided i.e. the provision of a 30 minutes (minimum) fire resistant wall which extends at least 300mm above and beyond the ends of the oil tank. It will be necessary to protect exposed eaves forming part of a roof within 1.8 metres of the top of an oil tank to provide a minimum of 30 minutes fire resistance. Cladding can be applied to the eaves in order to prevent fire from spreading to the roof. For oil tanks with a capacity of 3,500 litres or greater, please contact your local Building Control Officer or OFTEC.

Can I place an oil tank inside a domestic garage or building?

Internal oil storage tanks should never be installed in a habitable area and if installed internally, should always be contained within an enclosed chamber. Detailed requirements exist for internal oil storage installations. For more information contact your local Building Control Officer or OFTEC.

From what materials are plastic oil tanks manufactured?

All oil tanks supplied by Fuel Tank Shop are manufactured from Medium Density Polyethylene (MDPE) - a material that displays excellent chemical and impact resistance properties, making it ideal for external fuel storage. Fittings vary according to tank type and supplier. However, in general, fill points are made from either coated mild or stainless steel, outlets from coated mild steel, and vent points are manufactured from plastic. All materials used in the manufacture of oil tanks supplied by Fuel Tank Shop are resistant to the potentially damaging long-term effects of fuel.

What are the base requirements for plastic oil tanks?

All oil tanks must be installed on a flat, level and fire resistant base capable of supporting the weight of the tank when fully laden. If concrete slabs are used they should be a minimum of 50mm thick. The base should extend at least 300mm beyond the widest points of the tank and fully support the base of the tank in its entirety. Piers or pillars are not suitable for this purpose and can cause irreparable damage to the tank.

Are plastic oil tanks designed to protect from the damaging effects of sunlight?

Yes. Every tank sold by Tanks.ie is manufactured from a material which incorporated UV inhibitors. These prevent UV rays from permeating the structure of the tank, thus preventing fuel degradation.

Are plastic oil tanks suitable for the storage of fuel for aviation use?


Are plastic oil tanks fitted with sludge-valves / ball-cocks?

No. Openings (other than the tank outlet) are not permitted below the maximum level of fuel in the tank. This reduces the risk of accidental spillage. In the event that contaminants (e.g. water) need to be removed from the tank, they should be removed by an appropriately licensed contractor via the inspection aperture fitted to each tank.

I have discovered the presence of water in my oil. How do I get this removed?

Here at Fuel Tank Shop we offer a range of water soakers which can help remove water from your oil tank, however if these do not suit then, please contact your local fuel distributor who will be able to provide advice on how best to remove it.

Are plastic oil tanks suitable for use with oil fired cookers?


On warm days there is a slight smell of oil from my oil tank. Why?

This is perfectly normal and is simply the fuel venting through the weatherproof vent fitted to the oil tank.

Are plastic Oil Recycling Banks / Waste Oil Tanks suitable for the disposal of petrol or any other highly flammable liquid? 

No. For advice on how to dispose of petrol and any other similarly dangerous liquids, please contact your local authority.

Do you supply dip-sticks?

No - not as separate items. However, dipsticks are supplied as standard on all Harlequin tanks with a capacity between 650 litres and 2700 litres as standard.

Are Single Skin Oil Tanks or standard Bunded Tanks suitable for storing 'Adblue'?


Oil Tank Accessories

What is the difference between the Watchman Sensors?

The 3 main products that we sell in the Watchman range is the Sonic, Sensit & Sonic Advanced

Watchman Sonic:

The Watchman Sonic is the base level telemetry system we offer. This system works with a transmitter that will sit onto the top of your tank and will communicate with a 3 pin reciever plug inside your property to give you a ‘out of 10’ bar reading.

Watchman Sensit:

The Watchman Sensit is the upgraded version of the Watchman sonic.

This unit gives you up to date oil readings on your mobile phone thought the use of Wi-Fi.

Attach the transmitter onto the top of your tank, then plug the USB receiver into any USB port in the property (e.g. the back of the internet router or a 3 pin UK socket with USB port) within the WI-FI radius.

Once this is up and running you will then need to download the Kingspan app and go through the steps to get your tank linked. You will receive oil level readings and over time the app will work out your predicted run out date.

Watchman Sonic Advanced:

The watchman sonic advanced is the upgraded version of the Watchman Sensit.

This device can be purchased as just the transmitter and plug or a complete package of the transmitter, plug and USB dongle.

The transmitter and plug option gives you the option purchase the USB dongle later. (Please note. These 2 units do not need each other to work)

The Watchman Sonic Advanced Is installed using the same method as the Sensit and Sonic - The advanced unit allows you to have both options of oil level monitoring (In the property and via app).


If you would like to find out more on these until please visit their pages here: Sonic, Sensit, Sonic Advanced. Or pop into a chat, email or call us on 01643704328.


How accurate are oil tank gauges?

Just like in your car, oil tank gauges measure the level of fuel remaining by using a float. With visual oil tank gauges, you will see a dial or clock that tell you whether your tank is full, ¾-full, ½-full, ¼-full or near empty. Levels may also be displayed as a percentage. These provide a good estimate of how much oil you have left in your tank and are useful for letting you know when you may need more. Oil tank gauges usually have a rigid metal rod attached to a float inside the oil tank. As the oil is consumed, the float falls accordingly and the gauge reading drops. However, because the bottom of a fuel oil tank is usually rounded, the gauge will go from a quarter-full to empty quicker than it goes from half-full to a quarter. This means they are not completely accurate and should only be used as a guide as to how much oil remains in the tank.

For more precise oil tank readings, a smart oil tank gauge uses an ultrasonic sensor that can provide accurate readings to within a few litres.

How do you read the gauge on an oil tank?

This will depend on the type of oil tank gauge you have. Heating oil tanks that sit above the ground typically have a float gauge up top, which have an arm with a floating end on it. As oil is consumed, the float falls accordingly. The disc or needle on the indicator will move up and down as the float inside the tank moves, indicating the approximate level of oil in the tank. If your tank holds 1250 litres of oil, ½ a tank means approximately 625 litres remain. If the disc is showing ¼ of a tank, there’s 312 litres remaining and if it’s showing ¾ of a tank, there’s about 938 litres remaining. The levels may also be displayed as a percentage. 

If your oil tank gauge uses an ultrasonic sensor, like our range of smart oil tank gauges, you’ll be able to read a much more precise tank level by simply opening the app. Except for the top 8 inches of your tank, smart oil gauges will provide readings within a few litres in your tank.

Do I read the top or bottom of oil tank gauge?

Some people get confused when taking a reading on their oil tank gauge – whether they should use the top or the bottom as the indicator. Read the gauge on the top of the tank. It will tell you if your tank is full, three-quarters full, half-full, a quarter-full or near empty. The levels may also be presented as a percentage.

Because of the rounded bottom of an oil tank, you may notice that the gauge goes from a quarter-full to empty quicker than it goes from half-full to a quarter. For this reason, you should only use float gauges as an estimation of how much fuel is left in the tank and it is advisable to reorder oil when the gauge is reading ¼ full to avoid running out.

How do I know how much oil is in my tank?

You can find out how much oil is left in your oil tank by checking the oil tank gauge.

How you do this will depend on the type of oil tank gauge you have.

If you have a smart oil tank gauge, you’ll be able to read a more precise tank level by simply opening the app. You can usually set up notifications that will alert you when your tank is starting to run low. Or perhaps you’re using a visual oil gauge.

As oil is consumed, the float level drops and the disc inside the float gauge dial indicates the approximate level of oil in the tank – shown either as a percentage or full, ¾-full, ½-full, ¼-full etc. If you’re using a float gauge, it's a good idea to set a regular day to check your tank's oil level to avoid running out of oil. Set a reminder on your calendar or phone marking specific days to check your oil tank. It is also important to check that your gauge is in good working order.

If you’ve had your heating on but the dial hasn’t moved in a while, there's a good chance it's not reading the level correctly.

What can I do to prevent heating oil theft?

There are plenty of different things that you can do to keep your heating oil safe, including using a bunded oil tank to store it, fitting a tank alarm and setting up CCTV. Read our complete heating oil safety guide here.

How do I install a Watchman Sonic?

Here at Fuel Tank Shop, we can provide you with an easy step-by-step guide, helping you to correctly install your Watchman Sonic on to your tank. Read our complete installation guide here.

Is my oil tank Watchman SENSiT ready?

If your tank has an orange stcker, saying Watchman SENSiT ready. This means you should have the grey tranmitter Watchan Sonic Advacned pre-installed on your tank

What if my tank is not Watchman SENSiT ready, can i still use a SENSiT?

Yes you can. If your tank does not have the orange sticker and a grey Watchman Advanced transmitter, the SENSiT USB receiver will work not on its own. You will need to purchase the full SENSiT smart WiFi tank level monitoring kit, which contacins everything you need.

Can I fit a sight-gauge to a single skin oil tank?

Technically, sight-gauges can still be fitted to a single skin oil tank - subject to prevailing statutory requirements. However, it should be noted that a sight-gauge is a potential leak point and as an environmentally responsible supplier we do not supply them and do not recommend them. Preference should instead be demonstrated to fitting an electronic oil tank contents gauge, which, unlike a sight gauge, is positioned above the maximum level of fuel in the tank, thereby dramatically reducing the likelihood of an environmental pollution incident. An Apollo type electronic oil tank gauging system is fitted as standard to all Harlequin Advance Single-Skin Oil tanks supplied by Tanks.ie - eliminating the requirement to fit a sight-gauge.

Can I fit a sight-gauge to a Bunded Tank?

No. Please note however that all Harlequin Bunded Tanks (except 350BND/ENV), Harlequin Polyrock Bunded Oil Tanks, Harlequin BioBund Bunded tanks, and Harlequin Fuel Stations are pre-supplied with an electronic oil tank contents gauge, which removes the requirement for a sight-gauge to be fitted.

There is a two-pin type socket fitted to my Harlequin oil tank. What is this for?

This permits an LRC enabled delivery driver to plug in his overfill prevention equipment and is not for consumer use.

What are the advantages of a Tiger Loop?

The Tiger Loop is a de-aeration device which removes air from the fuel prior to combustion. The result is a cleaner, more-efficient burn, with reduced emissions and enhanced cold weather performance. Additionally, the Tiger Loop can permit the tank to be positioned lower than the burner and up to 30 metres away. Therefore when connected to a pressure jet burner, it is ideal for Top Outlet Bunded Tank installations and eliminates the need for an undesirable return line. Please note that Tiger Loops are unsuitable for use with installations incorporating a vaporising burner.

What liquids are the Apollo remote electronic gauges used to monitor?

Kerosene (C1/C2), Agricultural Fuel Oil (A2), Diesel (D) and Water.

Is an Apollo gauge compatible with a Watchman / Full Stop Handheld Unit?


How do I prime a Tiger Loop?

The Tiger Loop is self priming.

Does a Tiger Loop require batteries or mains power?


Do You Supply Dipsticks?

No – not as separate items. However, dipsticks are supplied as standard on all Harlequin tanks with a capacity between 650 litres and 2700 litres as standard.

Do You Sell Gravity Feed Kits for the Delivery of Diesel Fuel?

No, as an environmentally responsible supplier we do not supply these kits, due to the high risk of accidental damage / discharge associated with their use. Additionally, at many installations today their continued use is illegal. If you require a tank to store diesel fuel for vehicular use, we would advise you consider a Harlequin Fuel Station, or Fuel Point.

Sewage and Waste

Sewage Treatment Plants

Invert Depth, what is this?

It is the level of the soil pipe entering the septic tank or treatment system.

Gravity or IPS, what is the difference and when would I need them?

If the flow from your system can not release without help, i.e. required to be uplifted you would need a pump to help with this.

Septic Tanks

Septic tanks vs cesspools, which is best?

If you do not have sufficient area required to discharge the run out from a septic tank, you would need a cesspool which requires emptying on a 40 day cycle. Please contact us for help if required.

Due to the new regulations, do I need to upgrade to a Sewage Treatment System?

You would only need to upgrade your septic tank if the run off discharges to a water course.

Standard soak aways are still legal.

My old tank needs some parts replacing do you offer this?

Yes we offer the full range of Klargester replacement parts.

How to Discharge Waste from Septic Tanks

There are 3 options available:

(1) Connect to a main sewer if possible
(2) install a drainage field or
(3) install a sewage treatment plant which treats the wastewater, producing a clear overflow that is environmentally friendly and suitable for discharging.

To see our full range of sewage treatment plants click here

Why should I look after my septic tank system?

If your septic tank system is not in good working order it can be a serious risk to both health and the environment. You also have a legal responsibility to maintain your septic tank system. In looking after your septic tank system, it will have to be emptied less frequently, saving you money. A septic tank system can also be costly to replace if it fails.

What checks should I make on my septic tank system?

If your septic tank system is in good working order you should have the following:

  • Your household drainage should be quick to clear, and toilets should not be backing up
  • There should be no smell from your tank and the cover should be accessible and well fitting
  • The soak away should be dry not swampy, smelly or have prolific grass growth
  • A pale liquid with little or no smell should come from the discharge pipe. It should not be dark, smelly or contain solids
  • Makes sure to keep deep-rooted trees and plants at least 30 m away from your system. Keep the grass nearby short.

If any of the above is showing signs that your septic tank system is not in proper working order, you must get it repaired or replaced by a credited installer.

How often should I empty my septic tank?

Your tank should be emptied once a year so that you do not risk a build up of sludge which can lead to problems with your system. The company you use to empty your septic tank must be registered to do so.

Do I need to register my tank?

Yes you need to register your septic tank with your Local Authority – click here to register https://www.protectourwater.ie/. There is a charge of €50 to register.

Is the landlord responsible for emptying the septic tank?

If you own a property which you rent, or you are a tenant yourself, it can become a little less clear who has the responsibility to empty the septic tank. Maintenance and responsibility can be written into the tenancy agreement. If you are a landlord renting out a property with a septic tank you may need to put measures in place if you want the tenant to take responsibility for the septic tank. You may need an inspection or service after the end of any tenancy period. As a tenant, if it is written into the tenancy agreement that you have responsibility for the septic tank, you might also want to insist upon an inspection to ensure you aren’t inheriting any issues you would then be liable to pay for is one way to do this. Checking the schedule of maintenance and the obligations is another before any serious issues can occur. Following the guidelines of the septic tank is important too.

Do septic tanks need servicing?

You should have your septic tank system regularly maintained in accordance with the manufacturer’s instructions. If these are not available, ask your local maintenance company for advice. This will save costly repairs or replacement of the sewage system in the long term.

Does my septic tank need a permit?

Owners of properties connected to larger on-site systems where the discharge is in excess of 5 cubic metres per day do not need to register (i.e sports clubs, pubs, hotels, guesthouses and other businesses).  Instead such systems may require a licence from the relevant local authority under Section 4 of the Water Pollution Act 1997. 

How far should my septic tank be from the house?

Septic tanks should be at least 7 metres away from any dwelling. They should also be located within 30 metres of an access point so that the tank can be emptied.

What are some things that should not be put into the septic tank system?

  • Don’t flush anything other than bodily waste and toilet paper down the toilet
  • Don’t dispose of grease or oil down any drain – wipe out pans and pour fat into a container to be disposed of in the bin
  • Don’t put paints, solvents or chemicals down the drain
  • Don’t try to unblock pipes with caustic soda or drain cleaners. Try boiling water instead
  • Don’t connect rainwater pipes to your septic tank

What are your options when it comes to the Septic Tank Regulations

If your current system discharges directly into a water course, you will need to upgrade your system. To go through your options give us a call, and we can talk you through the various options.

Fuel Dispensing Tanks

Fuel Filters

What is a fuel filter?

Fuel filters are an essential component of any fuel system, as they are responsible for removing contaminants and impurities from fuel before it is used in vehicles, equipment, or machinery. These contaminants can include dirt, debris, rust, and other particles that can clog or damage fuel system components, leading to reduced performance and shortened lifespan.

There are several different types of fuel filters, each of which is designed to meet the specific needs of a particular fuel system. Some common types of fuel filters include:

  • Sediment filters, which are designed to remove large particles and debris from fuel. These filters may be made of paper, fiberglass, or other materials, and are typically used in gasoline or diesel fuel systems.
  • Water separators, which are designed to remove water from fuel. These filters are commonly used in diesel fuel systems, where water can accumulate and cause corrosion or other problems.
  • Carbon filters, which are designed to remove impurities and contaminants from fuel using activated carbon. These filters are often used in gasoline or diesel fuel systems, and may be used in conjunction with other types of filters.

Fuel filters are typically installed in the fuel line between the fuel tank and the engine, and are designed to be easily replaceable when they become clogged or dirty. It is important to regularly replace fuel filters to ensure that the fuel system is functioning properly and to prevent costly repairs or downtime.

In addition to their primary function of filtering fuel, fuel filters may also include features such as pressure regulators, which help to ensure that the correct amount of fuel is delivered to the engine, and anti-drainback valves, which prevent fuel from draining out of the filter when the engine is off.

Overall, fuel filters are an important part of any fuel system, and are essential for ensuring that fuel is clean and free of contaminants. Properly maintaining and replacing fuel filters can help to extend the lifespan of fuel system components, improve fuel efficiency, and reduce the risk of costly repairs or downtime.

Fuel Management Systems

How does a Fuel Management System protect my fuel?

A fuel management system protects your fuel by only allowing access to authorised persons.

The system allows you to assign key fobs (standard fuel management system) or mobile app licenses (B.SMART system) to certain users to grant them access to the pump and the fuel.

This access can also be stopped at any time to add further protection by deactivating the fobs or licenses at any time (usually in the case of an employee leaving the business or one going missing).

The computer system also gives you many benefits to protect your fuel such as:

  • Setting a fuel limit for users so they can overfill or underfill their vehicles.
  • Ability to disable the pump in the evenings or holidays.
  • Add extra references so the user must provide a reason as to why they are dispensing the fuel

Diesel Tanks

Are plastic diesel tanks better than steel diesel tanks?

Longevity and security are among the main reasons to select steel over plastic. That is not to say that a plastic tank will not last or hold up to opportunists trying to get at your valuable commodity however, but good points to consider. Also, steel are more resistant to outside forces. Read our complete guide of steel vs plastic tanks here.

HVO Fuel Tanks

What is HVO fuel?

Derived from renewable sources like vegetable oils and animal fats, hydrotreated vegetable oil fuel (or HVO) is synthesised through a process called hydrotreatment. During hydrotreatment, impurities are removed, and the molecular structure of the feedstock is modified, resulting in a cleaner-burning and more environmentally friendly fuel. With its similar composition to traditional diesel, HVO fuel can be seamlessly integrated into existing diesel engines and infrastructure.

When burned, HVO fuel emits fewer carbon dioxide, particulate matter, and other harmful pollutants compared to conventional diesel. This characteristic makes it an attractive option for combating air pollution and minimising the carbon footprint of vehicles and machinery, significantly reducing greenhouse gas emissions and air pollutants compared to traditional diesel. HVO fuel is well-suited for use in trucks, buses, construction equipment, and agricultural machinery. The compatibility with existing diesel infrastructure means you can seamlessly transition to HVO fuel without making significant modifications.

What are the benefits of HVO fuel?

HVO emits significantly fewer greenhouse gases and harmful pollutants when compared to traditional diesel. This means cleaner air, a minimised carbon footprint, and a positive contribution to combatting air pollution and climate change. Its seamless compatibility with existing diesel infrastructure means you won’t need to invest in extensive engine modifications or infrastructure changes – it can be directly blended with or used in place of conventional diesel, making the transition to this cleaner fuel hassle-free. Whether you're driving a personal car, operating commercial vehicles, or using heavy machinery, the versatility of HVO ensures a smooth integration without disruptions.

HVO fuel is derived from renewable sources such as vegetable oils and animal fats. By utilising these renewable feedstocks, you're contributing to a circular economy, reducing dependence on fossil fuels, and promoting responsible resource utilisation. HVO fuel also has a positive impact on engine performance and maintenance. Thanks to its cleaner combustion, this fuel can lead to reduced engine deposits, longer maintenance intervals, and improved overall efficiency. Your engines will run smoother, requiring less frequent servicing, that will help extend their lifespan.

Is HVO fuel cheaper than diesel?

The pricing dynamics of HVO fuel and diesel can vary based on a multitude of factors. At times, HVO fuel might appear to have a higher upfront cost compared to conventional diesel. This can be attributed to the production process and the relatively smaller scale of HVO fuel production in comparison to the well-established diesel industry. However, it's crucial to dig deeper and consider the long-term financial perspective.

One of the financial benefits of HVO fuel lies in its potential for enhanced engine performance and maintenance. HVO's cleaner combustion can lead to reduced engine wear and deposits, ultimately extending the lifespan of your engines and potentially offsetting the initial cost difference. As demand for sustainable fuels like HVO grows, economies of scale could come into play, gradually bringing down production costs and narrowing the price gap between HVO and diesel. In some regions, tax breaks and subsidies might be offered for using renewable fuels like HVO as part of efforts to reduce emissions and promote sustainability. This can make HVO fuel more financially attractive compared to diesel, especially when factoring in the broader environmental benefits. As technologies evolve and the renewable fuel sector advances, it's reasonable to anticipate innovations that could enhance the efficiency of HVO production and distribution. These could lead to more competitive pricing over time.

How long can I store HVO fuel?

HVO fuel boasts exceptional stability and a longer storage duration, allowing you more flexibility with your fuel management. At Fuel Tank Shop, we offer a wide range of HVO fuel tanks available in various sizes and materials, specifically designed to store HVO fuel safely and efficiently. When stored under proper conditions, HVO fuel can maintain its quality for up to 10 years or more – although the storage duration can vary depending on factors like the quality of the initial fuel and the presence of any contaminants.

The prolonged shelf life of HVO fuel is due to the rigorous hydrotreatment process during production, which results in a fuel with reduced susceptibility to degradation and contamination. It is advisable to regularly inspect your stored HVO fuel and look for any signs of water accumulation or sediment settling at the bottom of the storage container, as these can compromise the fuel's quality over time. If you spot any issues, it's recommended to address them promptly by filtering or treating the fuel as necessary.

Diesel Tanks

Can I store diesel in a transportable tank ?

A transportable diesel tank should be stored in a secondary containment area if it contains fuel as in most cases these are single skin.

These tanks are primarily designed for transporting fuel to a place of work to be completely discharged of fuel

Fuel Management Systems

What are the benefits of a Fuel Management System?

There are many benefits to a Fuel Management System being installed.

The main benefit of the system is the pump security. The Fuel Management System allows you to add and remove users’ ability to use the pump as per your requirements.

The key fob system or the user licences system (B.SMART phone app) will give you control of who can use the system and eliminate the worry of unauthorised users for dispensing fuel.

By using these systems, it gives you the ability to add a user and stop a user from using the pump whenever you need to. If any key fobs or mobile phones go missing with approval to use the pump you can easily inactivate these to prevent the possibility of fuel going missing.

Another benefit this system has been the ability to shut off the pump when out of hours and holiday periods when no one will be on site. This is does very easily on the software on your desktop.

Another key benefit for the admin perspective will be when the users dispense fuel, the transactions are logged and transferred to the desktop software which will allow you to run reports. These reports are useful because they will show dates, times and litres dispensed so every litre can be accounted for. Any missing litres you will easily be able to check the report and find out why.
You can also add a reference option (such as registration number) for more information to what the fuel is being used for.

Lastly, this system also allows you to cap the usage for drivers. If you only require your driver to use 30 litres then you can assign the pump to cut out once 30 litres has been dispensed, and if you don't find it important for your user to see the litres dispensed you can turn this feature off (Good for companies who prefer the users to fill until full)

What is the difference between the Piusi fuel management system and the B.SMART fuel management system?

The difference between these units is the way you are able to access the unit.

The Piusi Cube 70MC Fuel Management System and the Piusi MC Box Management System are the range of fuel management systems that require user keys and a manager key to be able to extract the data.

This system requires each user to assisned a yellow key fob (This can be allocated to a person or registration number) - this will allow access and link the usage to the individual.

Once this data has been stored on the box the person incharge of extracting the data will use the manager key with the unit. Once the manager key has been been used with the box you will then take it to your computer and use it with the key fob reader.

The key fob reader will come with your software package and this will allow you to store your data and also collab and run reports.


The Piusi Cube MC B.SMART Fuel Management System and the Piusi MC Box B.Smart Fuel Management System are a range of systems that dont require any user key fobs. Instead these use a phone app and user licenses to allow access to the pump.

These systems are connect via bluetooth and uses the phones mobile data to record and store the data.

The B.Smart unit is a cloud based system and no software needs to be purchased to be able to store and view the data instead you log onto a website to find everything. There is no ongoing subscriptions fees for this unit and the website access is included in the cost of the unit.

If your tank is located in a place where wifi isnt available then your system is able to hotspot using a mobile phone to get the data to the cloud.

Diesel Tanks

What type of plastic is used for diesel tanks?

At Fuel Tank Shop, our diesel storage tanks are commonly manufactured from high-density polyethylene (HDPE) or cross-linked polyethylene (XLPE) due to their excellent chemical resistance and durability. These types of plastics are specifically chosen for their ability to withstand the corrosive nature of diesel fuel and provide a reliable storage solution. High-density polyethylene is known for its strength, impact resistance, and flexibility, making it a suitable material for manufacturing diesel tanks that can endure various conditions. Cross-linked polyethylene, on the other hand, offers enhanced resistance to temperature extremes and improved structural stability. This makes XLPE an excellent choice for diesel tanks exposed to fluctuating environmental conditions, ensuring they remain robust and reliable over time. Both HDPE and XLPE contribute to the overall longevity of the diesel tank by preventing degradation and maintaining their structural integrity.

These plastic materials are often moulded using rotational moulding or blow moulding techniques. Rotational moulding creates a one-piece tank without seams or joints, minimising the risk of leaks and ensuring a solid, durable container for diesel storage. The plastic used for diesel tanks is formulated with additives to provide protection against ultraviolet (UV) radiation, which is crucial, especially for outdoor tanks, as it prevents the material from becoming brittle and degrading when exposed to sunlight.

Fuel Management Systems

What is a fuel management system?

A fuel management system is a device or software application that is used to track and monitor fuel consumption and usage in vehicles, equipment, or machinery. It is designed to help businesses, fleet managers, and individuals better understand how much fuel is being used and where it is being used, in order to optimize fuel efficiency and reduce costs.

The system typically includes sensors that are installed on the vehicle or equipment to measure fuel consumption and usage, as well as a central control unit or software application that collects and processes this data. The data collected by the sensors is transmitted to the central control unit or software application in real-time, allowing users to track fuel usage and consumption in real-time.

The central control unit or software application includes a user interface, such as a dashboard or app, which provides real-time data and analytics on fuel usage and consumption. The user interface allows users to view fuel consumption data in various formats, such as graphs, charts, and reports. This data can be used to identify trends and patterns in fuel usage and consumption, and to identify areas where fuel efficiency can be improved.

Some fuel management systems also offer features such as alerts for low fuel levels, route optimization to reduce fuel consumption, and the ability to track fuel costs and compare them to budgeted amounts. These features can help businesses and individuals make more informed decisions about fuel usage, leading to significant cost savings over time.

In addition to tracking and monitoring fuel consumption, some fuel management systems also include features such as fuel theft prevention and fuel budgeting. Fuel theft prevention features can help businesses and individuals detect and prevent unauthorized fuel usage, which can lead to significant cost savings. Fuel budgeting features allow users to set budget limits for fuel usage and track fuel costs against these limits, helping to control fuel expenses and improve overall financial management.

Overall, a fuel management system is an essential tool for businesses, fleet managers, and individuals who want to optimize fuel efficiency, reduce costs, and improve overall financial management. It provides real-time data and analytics on fuel usage and consumption, and offers a range of features to help users make more informed decisions about fuel usage and improve overall fuel efficiency.

Diesel Tanks

Do plastic diesel tanks deteriorate over time?

Yes, plastic diesel tanks can experience deterioration over time, but the extent of this degradation depends on various factors such as the quality of the tank’s material, environmental conditions, and maintenance practices. Polyethylene, commonly used in plastic diesel tanks, is known for its durability and resistance to corrosion. However, exposure to certain environmental elements, such as prolonged sunlight or extreme temperatures, can contribute to the gradual breakdown of the plastic.

UV radiation is one of the primary culprits for the deterioration of plastic tanks. Over time, sunlight can cause the material to become brittle and lose its structural integrity. To mitigate this, many of our plastic diesel tanks are manufactured with UV-resistant additives to prolong their lifespan. Regular inspection and application of UV protectants, if necessary, can further safeguard the tank against these environmental effects.

Environmental conditions, such as fluctuations in temperature and exposure to harsh chemicals, can also impact the longevity of plastic diesel tanks. Extreme temperature variations may lead to expansion and contraction, potentially causing stress on the tank walls. Additionally, contact with certain chemicals or fuels other than diesel may accelerate the deterioration process. Choosing a tank designed for compatibility with diesel fuel and adhering to proper usage guidelines can help mitigate these risks.

Routine maintenance plays a crucial role in preventing and addressing deterioration. Regular inspections for signs of cracks, leaks, or changes in the tank's structural integrity are essential. It's important to follow manufacturer recommendations for maintenance of our diesel tanks and address any issues promptly, such as applying sealants or replacing damaged components.

How long does diesel last in a transfer tank?

The answer to this question depends on several factors, including the quality of the diesel, the environment the tank is stored in, and the type of transfer tank being used. Generally speaking, diesel fuel stored in a transfer tank will last between six and twelve months. However, this time frame can vary depending on the factors listed previously. For example, if the diesel is of high quality and stored in an environment that is not prone to extreme climate changes, then the diesel may last up to twelve months. However, if the diesel is of lower quality and stored in a harsh environment, then it may only last for six months. Additionally, if the tank is not properly sealed, then the diesel may not last as long, as air can contaminate the fuel and cause it to deteriorate more quickly.

When it comes to selecting the right type of transfer tank for your diesel storage needs, we have several options available. Each type of tank will have its own pros and cons, and the best option for you will depend on your unique needs and budget. If you’d like any help choosing the right diesel transfer tank, contact our friendly team who will be happy to help.

How long can diesel be stored in a steel tank?

Storing diesel in a steel tank offers durability and longevity, but the duration for which diesel can be stored depends on several factors. Generally, diesel can be stored in a well-maintained steel tank for an extended period, often up to 12 months or more, without significant degradation. However, the key to preserving the fuel quality lies in proper storage conditions, preventive measures, and regular maintenance of the tank.

One critical factor affecting diesel storage in a steel tank is the prevention of water contamination. Moisture can promote microbial growth and lead to fuel degradation. Well-designed steel tanks often incorporate features to minimise water ingress, such as effective sealing and proper tank positioning to avoid condensation. Periodic inspections for water accumulation and the use of water-absorbing filters contribute to maintaining fuel quality over time. Implementing protective coatings on the tank interior and exterior, such as epoxy or specialised anti-corrosion treatments, helps mitigate the impact of corrosive elements. Regular inspections to detect and address any signs of corrosion are essential for ensuring the structural integrity of the tank and preserving the quality of the stored diesel. Lower temperatures help slow down oxidation and microbial growth, contributing to the preservation of fuel quality. Adequate ventilation and insulation of the storage area can assist in maintaining a consistent temperature within the steel tank, reducing the risk of temperature-related degradation.

To maximise the duration for which diesel can be stored in a steel tank, it's crucial to adhere to recommended storage guidelines, conduct routine inspections, and implement preventive measures. By maintaining proper storage conditions, you can extend the storage life of diesel in a steel tank and ensure a reliable and consistent fuel supply when needed.

Can I have a flow meter on my diesel tank if fitted with a hand pump or if gravity fed ?

No. Unfortunately the pressure required to enable the flow meter to read accurately is not at a tolerance that the flow meter can record

Why can't I have an automatic shut off nozzle on my diesel tank if fitted with a hand pump or if gravity fed ?

Unfortunately the automatic nozzle requires a pressure of the fuel being pumped to operate the shut off mechanism.

A hand pump or gravity fed tank would not have the necessary pressure to enable this

What is the new legislation for the change of rules for red diesel ?

The red diesel rebate has been a hot topic amongst many industries over the last year. However, after careful consideration earlier this year, the Chancellor and the government have decided to proceed with abolishing the use of red diesel from the 1st April 2022 in a number of sectors, to help reduce the impact that fossil fuels have on the planet. Specifically, their aim is to reduce commercial use of red diesel, especially in the plant and construction sectors, and to encourage the use of other fuels such as white diesel or alternative greener options. So how some industries will be affected and what do they need to know to prepare for the new legislation?

Restrictions on the use of red diesel come into force on 1st April 2022 for a range of industries including plant, construction, leisure, mining, quarrying, road maintenance and logistics. This means that there are less than 5 months to get ready to make sure that you comply with the new regulations from April. So here are a few things that you need to know:

  • From 1 April 2022, Registered Dealers in Controlled Oils will need to flush their tanks and supply lines when switching a fuel tank from red to white diesel, so there is no trace of the rebated fuel.
  • End users that are losing their red diesel entitlement will need to make sure that they run down their existing stocks and do not purchase red diesel from 1 April 2022.
  • The government has recognized that some users such as data centres are holding large amounts of red diesel but may only use it for a few hours a year in case of emergency. So it has been decided that HMRC will investigate and decide if the user can provide enough evidence that they have not built up their stocks or taken red diesel after the rules changed.
  • As the price of red diesel is a lot lower compared to the average price of white diesel, users will see an increase in how much they spend on fuel
  • As white diesel is so much more expensive and also widely used by the public, it needs to be considered that a rise in fuel thefts may occur once the switch has been made, meaning those storing fuel on-site need to consider protecting their fuel, as well as controlling and monitoring its use amongst staff

Transport/Fleet and Plant Hire

These industries will no longer be able to fuel their vehicles on-site using red diesel, they must make the switch over to an alternative fuel. This will involve running down or removing red diesel from vehicles, machinery and/or fuel storage tanks. There’s a possibility that they will be able to sell back any excess stock of red diesel to fuel suppliers which will help towards funding the cost of replacing the fuel.

The cost of refuelling vehicles and machinery, or filling up storage tanks, will see an increase due to the difference in price between red diesel and alternative fuels such as white diesel. This will happen regardless of whether refuelling at a public petrol station or on-site using their own storage and dispensing equipment. One of the most important things that these industries need to consider is securing their site, any fuel storage tanks, and the vehicles or machinery such as diesel-powered chiller units on trucks, forklift trucks and mobile generators, to protect against theft, as well as unauthorized fuel dispensing

2. Engineers

As more industries will switch over from red diesel to alternative fuels, engineers will see an increase in jobs relating to fuel security and fuel management systems being required on-site or at business premises. This may require extra labour to implement these changes (depending on the size of the team), and extra training on products and installation (depending on the type of equipment being installed). Furthermore, it’s likely that you’ll also see an increase in call out jobs to assist with breakdowns, maintenance and further installs or changes to equipment.


 3. Fuel Suppliers

The increase in demand for white diesel and other alternative fuels that are more expensive might result in more customers contacting fuel suppliers about fuel security options and to find more information on how they can manage the fuel usage on their site. We believe that as industries are starting to switch over fuel suppliers may see a surge in enquiries for fuel management systems, gauging, fuel monitoring and security solutions. So, our technical and sales team will be on hand to support fuel suppliers offering expert product selection advice and helping their customers to find the right products that match their applications and requirements

How secure are the diesel dispensing tanks ?

All the diesel dispensing tanks that we sell are bunded which is a term that literally means a `tank within a tank'. This is designed to keep the fuel safe in the very rare event should the inner tank split. The cabinet doors can be locked either with a key or in some instances the tank is supplied with a metal post which the customer can secure with their own padlock

Advanced diesel dispensing tanks can sometimes be offered or come with fuel management systems which would only allow authorized people with key fobs to dispense fuel

Can we install a diesel dispensing tank ?

No. We are not able to install a diesel dispensing tank but there are companies out there that are able to install, service & decommission old tanks. Please contact us for details

Does diesel react with galvanised steel?

Yes, diesel fuel can react with galvanised steel under certain conditions, posing potential issues with fuel quality and storage equipment. Galvanised steel is coated with a layer of zinc to protect it from corrosion, but diesel fuel, particularly ultra-low sulphur diesel (ULSD), contains compounds that can react with the zinc coating. Over time, this reaction may result in the formation of sediments or precipitates in the fuel, potentially leading to filter clogging and fuel system problems.

The reaction between diesel and galvanised steel is more likely to occur in the presence of water or moisture. If water is introduced into the fuel tank, it can accelerate the corrosion of the zinc coating, releasing zinc ions into the diesel fuel. These ions can then react with other components in the fuel, forming insoluble compounds that can contribute to filter plugging and compromise the efficiency of the fuel system.

To minimise the risk of diesel reacting with galvanised steel, it is advisable to prevent water ingress into the fuel storage system. Regularly inspect the tank for signs of water accumulation, ensure proper tank sealing, and consider installing water-absorbing filters to remove any moisture from the fuel. Additionally, using fuel additives designed to stabilise and improve the quality of stored diesel can help mitigate potential reactions with the galvanised steel. It's essential to follow best practices for fuel storage and maintenance, including routine inspections, to identify and address any signs of corrosion or degradation in the storage tank.

Do you sell gravity feed kits for the delivery of diesel fuel?

No, as an environmentally responsible supplier we do not supply these kits, due to the high risk of accidental damage / discharge associated with their use. Additionally, at many installations today their continued use is illegal. If you require a tank to store diesel fuel for vehicular use, we would advise you consider a Harlequin Fuel Station, or Fuel Point For BioDiesel applications, Harlequin BioFuel Stations are recommended for BioDiesel blends of up to B100. Alternatively, for connection to remote pedestal type dispensing units, Harlequin's BioBund range is ideal. Please note that all BioDiesel tanks supplied by Tanks.ie are suitable only for use with BioDiesel produced in accordance with European Standards.

What are the power requirements for mains powered diesel dispensing tanks ?

A single phase (domestic 240v mains) power supply is required and always recommended being connected to a Residual Current Device (RCD) fitted at the connection point to the power supply. All mains electrical installations must only be undertaken by a qualified electrician and must be inspected and tested regularly in accordance with statutory requirements. Alternatively an electrician can wire up to a standard 3 pin plug and would not affect warranty.

What liquids are diesel dispensing tanks suitable for storing and dispensing?

Diesel (D) to British Standard BS2869. Additionally, the diesel dispensing tanks we sell are also suitable for the storage and dispensing of Bio-Diesel with a bio-element of up to 5% concentration.

Can I store and dispense Kerosene (C1/C2) from a diesel dispensing tank ?

No. The pumps and ancillary equipment fitted to these products are suitable only for use with Diesel. Dispensing a non-approved fuel from this equipment could result in serious injury or death.

Are the flow meters fitted (if fitted as standard or as an upgrade) to diesel dispensing tanks suitable for the resale of fuel?

No. Any equipment that is required to be sold would require a Weights & Measures certificate. All the diesel dispensing tanks we sell do not have certified equipment

Are batteries supplied as standard with 12v equipped pumps on the diesel dispensing tanks ?

No. The 12v pumps would come supplied with battery cables and crocodile clips to connect to a battery outside of the tank. We are unable to provide batteries.

Are diesel dispensing tanks suitable for dispensing 'Adblue'?

No. These tanks would not have the correct type of pump and AdBlue solution requires stainless steel connectors which are not used in diesel tanks


Does the tank require any assembly after delivery ?

No. The diesel dispensing tanks that we sell, excluding the CEMO UNI & MULTI tank range, are assembled at the factory. Once delivered, the customer simply positions the tank, connects to the electrical supply and fill with diesel and the tank is ready to use

Hot Water Cylinders


How do I choose a hot water cylinder?

There are lots of hot water cylinders available in a range of different styles and sizes. What hot water cylinder you should choose will depend on several factors. These include the type of boiler you have and how much hot water you’ll need. Larger households will obviously need larger cylinders. You’ll want to allow approximately 50 litre capacity per person, although you should consider personal habits. Someone who likes to have a lot of baths may use more hot water than someone who takes regular quick showers.

Choose between vented and unvented hot water cylinders. Unvented hot water tanks connect directly to the mains water supply, so you won’t need separate cold-water storage tank. They are fed by pressure, rather than gravity, so can be installed almost anywhere in the home. Vented hot water cylinders are connected to a separate cold-water tank, not the mains water supply.

How Does a Hot Water Cylinder work?

Most hot water cylinders are heated by an external heat source such as a gas boiler or heat pump. The hot water is heated by the heat source and then travels through a copper coil in the hot water tank. The heat is then transferred from the from the external heat source to the water inside the hot water tank which is then connected to a tap or shower outlet.

How much does it cost to install a new hot water cylinder?

If you’re simply replacing a hot water cylinder in an existing system and in the same location, the job will be more straightforward than a fresh new installation. However, there are a few factors that can affect the installation cost when replacing a hot water cylinder. Smaller cylinders are quicker, and therefore cheaper to replace, than larger cylinders as they take less time to drain the water out before they can be swapped out. Twin coil cylinders are more expensive to install than indirect cylinders. And direct cylinders are the quickest and cheapest to install. Replacing a vented direct cylinder with an unvented direct cylinder in the same location requires the installer to drain and isolating the old cold-water tank and add new pipework and fittings where needed.

If you are looking to replace a combi boiler with an indirect hot water cylinder, you will want to factor in extra budget for moving existing pipework, changing the flue, which could involve scaffolding for safe roof access, as well as decommissioning the old combi boiler.

The price for installing hot water cylinders also varies depending on the type of cylinder you are installing. Material prices can also fluctuate, as well as factors including the size and requirements of your home, the job, the quality of the products you use, and whereabouts in the UK you’re based. Always make sure the installer’s qualified for the job.

Do hot water cylinders use a lot of electricity?

The size of your hot water cylinder, the insulation quality, your usage habits, and the heating method will all have an impact on its energy consumption. Larger cylinders require more electricity to heat a greater volume of water, which could lead to higher energy consumption, whereas smaller cylinders will use less electricity but may provide a limited supply of hot water. Well-insulated hot water cylinders retain heat more effectively, reducing the frequency of reheating – lowering electricity consumption. If you use hot water frequently, especially during peak hours, your electricity usage will be higher. To minimise electricity consumption, consider scheduling hot water use during off-peak times and use energy-efficient appliances.

Electric hot water cylinders are relatively common, but there are alternatives such as gas or solar water heaters, which can significantly reduce electricity usage. Evaluating these options may help you make a more energy-efficient choice.

With so many factors impacting the electricity usage of a hot water cylinder, it’s a good idea to carefully assess the cylinder size you choose and its insulation to help reduce electricity usage and save money on energy bills.

Is a hot water cylinder better than a boiler?

The choice between which is better, a hot water cylinder or a boiler, will depend on your specific needs and circumstances. You’ll want to consider the size of your household, the demand for hot water, the space that you have available, and your personal preferences.

Hot water cylinders provide a dedicated reservoir of hot water that is available for various domestic needs such as showers and baths. They can work with different heating sources, including boilers, solar panels, or electric immersion heaters, offering flexibility in choosing the most energy-efficient and cost-effective method for you. Hot water cylinders are often a preferred choice for larger households with a higher demand for hot water, and allow you to combine multiple heat sources for increased energy efficiency.

Boilers are typically more space-efficient, making them a practical choice if you have limited space. They heat water on-demand, which can be more energy-efficient if you have a well-insulated home with an efficient heating system, as it avoids heat loss in a storage tank. Boilers are generally easier to maintain and require less maintenance compared to hot water cylinders.

Both systems have their advantages, and the ‘better’ option will depend on your specific requirements. Our friendly team is on hand to help you make an informed decision – just get in touch today.

What are the different types of hot water cylinders?

Unvented hot water cylinders

These hot water cylinders are connected directly to the mains water supply, so you won’t need a cold-water storage tank. They can be installed almost anywhere in your home as they fed by pressure, rather than relying on gravity.


Vented hot water cylinders

Vented hot water cylinders are not connected to the mains water supply. Instead, they get their water supply from a cold-water tank to which they are connected.


Direct hot water cylinders

Designed with immersion heaters within the cylinder itself, direct hot water cylinders heat the water directly. Lookout for models that use multiple heaters to keep the water hot.


Indirect hot water cylinders

Indirect hot water cylinders require an external source of heat, like a boiler. They are sometimes fitted with an immersion heater as a backup heater or for boost functions.


If you need any help or advice on what type of hot water cylinder is right for your property, get in touch with our friendly team today.

What is the most efficient hot water tank?

If your hot water cylinder is nearing the end of its life and you’re thinking of replacing it, you’ll be pleased to know that, thanks to government regulations, you now have better choices and options that require water heaters to be more energy efficient.

And it’s not just the efficiency of the hot water tank you should consider; how much water you consume also plays a part and will impact your bills. Here are a few ways to lower your heating costs:

  • Use less hot water
  • Don't let hot water cool down before you have used it
  • Heat your hot water to a lower temperature

How do I know if my heating system is a vented or unvented system?

The main differences between a vented and an unvented system is the way the water supply works. With vented or “open” systems, the water supply comes from a cold water tank in the loft. This then uses gravity to carry the water via a “vent pipe” to the hot water cylinder. The cylinder can be copper or stainless steel, and usually lives in an airing cupboard. Because heated water expands, there needs to be somewhere for the expanded hot water to go. In the case of vented systems, the excess water will push back up the vent pipe and back into the tank in the loft.

With unvented systems, the water supply comes directly from the mains water. In the case of unvented systems, when the heated water expands, the expanded water goes into either a separate external expansion vessel (usually installed above the hot water cylinder), or the hot water cylinder itself has an internal expansion vessel. You’ll hear this referred to as a “bubble top” cylinder. As with vented cylinders, the cylinder can be copper or stainless steel, and usually lives in an airing cupboard.

What hot water cylinder do I need for my heating source?

When the only option for the property is to heat the cylinder electrically through an immersion heater, you need to select a “direct” cylinder. When you have a conventional boiler as a heat source, you need to select an “indirect” cylinder. When the property has rentable heat sources available, you need to select either a “solar indirect” or “heat pump” cylinder. Solar indirect cylinders feature two heat exchanger coils, one for connecting to the solar heat source and the other for connecting to a conventional boiler for when insufficient solar energy is available.
When dealing with any unregulated heat source or there are multiple heat sources available, a “thermal store” will usually provide the best solution.

What size hot water cylinder do I need?

For those not familiar with hot water storage, it is important to remember it is usually held at about 60°C, but is intended to be mixed with cold water down to a usable temperature. A bath using 100 litres of hot water at 40°C actually only equates to 60 litres at 60°C. A shower can use 18 litres of hot water per minute at 40°C, which is only 11 litres at 60°C.
The following average consumption levels of hot water (40°C) per person per day can be used as a guide:

  • Low consumption = 20–30 litres
  • Average consumption = 30–50 litres
  • High consumption = 50–70 litres

How long does a hot water tank usually last?

As hot water tanks are typically sealed, it’s often hard to tell how long a tank will last. So, the best way to estimate its life expectancy is to determine its age. Depending on the quality of the tank and how well it has been maintained, hot water cylinders can last anywhere up to around twelve years.

When the time does come to replace your hot water tank, Fuel Tank Shop have a wide range of tanks for you to choose from. Make sure that you choose a tank that will fit and, if your space is limited, our range of slimline hot water cylinders are usually taller and slimmer than standard hot water tanks. Although they tend to lose more heat than shorter fatter cylinders, they can often allow you to get through those narrow loft hatches or fit the hot water tank in a tight airing cupboard.

What if I can’t fit a standard hot water cylinder in my airing cupboard?

With a smaller footprint to height ratio, slimline cylinders can often allow you to get through those narrow loft hatches or fit the cylinder in a tight airing cupboard. However, you will be compromising on the cylinders’ energy efficiency slightly, as tall cylinders such as these lose more heat than shorter fatter cylinders.
Another space-saving solution, a horizontal cylinder allows you to maintain cylinder capacity in situations where height restrictions apply. However, you should be aware horizontal cylinders are marginally less energy efficient with slightly higher heat loss.

What are the signs of a hot water tank going bad?

Your hot water tank won’t last forever. Even the best hot water tanks that have been regularly serviced will only last around eight to twelve years. If your hot water tank is getting on, it’s a good idea to be aware of the signs that it’s starting to fail. You’ll want to replace your hot water tank before it fails if you don’t want to be without hot water! Here are a few signs that it’s time to replace yours.

It's old

If your hot water tank is over ten years old, it might not necessarily be failing but it does mean you’ll soon need a new one. Over time sediment builds up in the tank making it increasingly hard to heat the water.


It’s leaking

Leaks could just be the result of a loose seal or a valve that needs replacing, or it could be that your tank has cracked or corroded.


Your water is cloudy

Cloudy or rusty water could point to a problem with your hot water tank. Sediment may have built up in the tank or there may be rust in the tank or pipes.


Not enough hot water

Over time sediment builds up in the tank. This sediment means more energy is needed to heat the water in the tank. If your tank is no longer producing enough hot water your hot water tank could need replacing.


It’s noisy

If too much sediment has built up in the tank, it will need to work extra hard to heat the water. This can cause popping and rumbling sounds.

Where are fuel dispensing pumps typically used?

Fuel dispensing pumps are mainly installed on static fuel storage tanks. They can be purchased as a complete unit with a tank, or they can be retrofitted to existing tanks.

Typically, fuel transfer pumps are used in non-resale refuelling environments as it is not weights and measures approved. (If a weight and measure pump is needed, we ask for you to contact us or send us an email on sales@fueltankshop.co.uk so we can discuss your requirements).

The fuel dispensing pump is an ideal solution for the refuelling of fleets of vehicles, agricultural machinery as well as plant equipment.

Can I use diesel transfer pumps for kerosene?

Unfortunatly no. Kerosene has a lower flash point that diesel.

Because of this lower flash point there will be a greater chance of a spark resulting in ignition during the pumping phase.

**Please note: All kerosene, just like petrol must be ATEX approved, meeting they are certified as being safe for use in potentially flammable environments**

What types of pumps are suitable for diesel?

A hand fuel transfer pump can be used to move fuel from one container to another. Useful in many different industries, including automotive, industrial, and agricultural, hand fuel transfer pumps are designed to be lightweight and portable, making them ideal for use in remote locations or in areas where power is not available. They can be used for refuelling vehicles, boats, and other equipment.

If you’re working remotely or travelling to areas where there isn’t mains power, 12v pumps are a good option. These types of pumps come with two crocodile clips that you attach onto a power source such as a car battery. Our 230v diesel pumps are more popular for use with static tanks on a working farm, for example, and tend to come with a 3-pin caravan plug or a 3-pin UK domestic plug. 

Our engine driven fuel transfer pumps are an efficient way to move fuel from one location to another. These pumps are powered by an electric motor and are generally used for transferring fuel from a storage tank to a vehicle or other equipment. Available in a range of sizes, they can be used for a variety of applications in agricultural, industrial, and commercial. Learn more about these products with our helpful guide to diesel pumps.

How long can a 12V pump run on a battery?

This will depend on several factors, including the type and size of the battery, the pump's motor efficiency, and the amount of fuel being transferred. A fully charged 12V pump should run for several hours. However, if you are transferring a large amount of fuel or using the pump for an extended period, the battery may run out of power more quickly. It helps to choose a high-quality battery with a high amp-hour rating. Additionally, you can reduce the strain on the battery by using a pump with a more efficient motor, or by using the pump intermittently rather than continuously. It is also important to monitor the battery's charge level and recharge it as needed. Some 12V pumps come with built-in battery monitors or low-voltage shut-off features to help prevent damage to the battery.

Can I use a 18v battery on a 12V pump?

It is not recommended to use an 18V battery on a 12V pump. This is because the voltage of the battery needs to match the voltage of the pump to ensure proper function and prevent damage to both the pump and the battery. When you use a battery with a higher voltage than the pump is designed for, the motor in the pump will spin faster than intended. This can cause excessive wear and tear on the motor, which can lead to overheating, damage to the pump's internal components, and even total failure of the pump. In some cases, a pump may have a voltage range that it can operate within, which could allow it to function with an 18V battery. However, it is always best to consult the manufacturer's instructions and specifications before using a battery with a different voltage than what is recommended.

Oil Pumps

What is the most common type of oil pump?

Recognised for their simplicity, efficiency, and versatility, gear pumps are one of the most popular types of oil pumps, widely used across various industries. The design typically involves two meshing gears within a housing. As the gears rotate, they create a suction that draws oil into the pump, and as the gears mesh, they discharge the oil, creating a steady flow. The straightforward design of gear pumps make them reliable and easy to maintain, contributing to their popularity.

Gear pumps come in two primary variations; external gear pumps and internal gear pumps. External gear pumps, with gears located outside the housing, are suitable for low to medium viscosity fluids, making them ideal for a wide range of oil transfer applications. Internal gear pumps, where one gear is inside another, are capable of handling higher viscosities and are often employed for more demanding oil transfer tasks.

When considering the most common type of oil pump, it's essential to acknowledge the widespread use of centrifugal pumps as well. While more commonly associated with water and other low-viscosity fluids, centrifugal pumps are also employed in the oil industry. These pumps use an impeller to create a centrifugal force that propels the oil outward, generating a continuous flow. Centrifugal pumps are known for their efficiency and suitability for high-capacity applications, making them common in large-scale oil transfer operations.

How does an oil transfer pump work?

Typically, oil transfer pumps function on the principle of positive displacement, ensuring a consistent and controlled flow of oil from one location to another. The pump's core components include an electric motor, which provides the necessary power, and a mechanism that displaces a specific volume of oil with each cycle. As the oil transfer pump initiates operation, it creates a vacuum or suction force that draws oil into the pump chamber. This suction is typically facilitated by the movement of pistons, vanes, or gears within the pump, depending on its design. These components work together to create a low-pressure zone, allowing oil to be pulled into the pump from the source, such as a storage tank or reservoir. Once the oil is within the pump chamber, the positive displacement mechanism comes into play. Pistons, gears, or vanes compress and displace the oil, creating pressure within the pump. This pressure forces the oil out of the pump through the discharge port and into the designated destination, whether it's another container, a processing unit, or any other part of the industrial process.

Oil transfer pumps can come in various designs, including gear pumps, vane pumps, and piston pumps, each with its unique positive displacement mechanism. Gear pumps, for instance, utilise meshing gears to create the displacement, while vane pumps use sliding vanes, and piston pumps rely on reciprocating pistons.

What are the benefits of an oil transfer pump?

One of the primary advantages is the capability to control the flow of oil with precision. Oil transfer pumps are designed to provide accurate and consistent flow rates, ensuring that the right amount of oil is transferred to its destination. This level of control is crucial for maintaining the integrity of processes, reducing waste, and optimising resource usage.

Another notable benefit is the increased speed and efficiency of oil transfer operations. These pumps are engineered to handle various viscosities, allowing for swift and smooth transfers, even with high-viscosity oils. The streamlined process not only saves valuable time but also enhances overall productivity within your operations. Whether you are moving oil between containers, from storage tanks to processing units, or within complex industrial systems, the efficiency gained with an oil transfer pump is invaluable.

By automating the transfer process, they reduce the need for manual handling of oils, minimising the risk of spills, leaks, and worker exposure to potentially hazardous substances. The controlled and contained nature of pump operations adds an extra layer of safety, ensuring a secure working environment for your team.

Flexibility is another key advantage of oil transfer pumps. These pumps come in various types and designs, allowing you to choose one that aligns with the specific needs of your operations. Whether it's a gear pump for moderate-viscosity oils or a centrifugal pump for high-capacity transfers, the versatility of oil transfer pumps makes them suitable for a wide range of industrial applications. Their adaptability ensures that you can tailor the pump to meet the unique requirements of your oil transfer tasks.

Through precise control, increased efficiency, and reduced manual handling, these pumps help minimise waste, optimise energy consumption, and decrease operational costs. The initial investment in an oil transfer pump is quickly offset by the long-term benefits of improved productivity, safety, and resource utilisation, making it a valuable asset for any industry involved in oil handling and transfer.
