How it works
Being a direct cylinder, the JAB DUC 2 170L uses an immersion heater to heat the water stored inside. Connected to the mains supply, it delivers pressurised hot water directly to taps and showers without the need for a cold water tank. This makes it an excellent choice for properties without a central heating boiler or where additional hot water storage is required.
The unvented design means water is supplied at mains pressure, offering a more powerful flow compared to traditional vented cylinders.

JAB DUC 2 170L Direct Unvented S/S Cylinder Delivery Information
Tanks:
The delivery of a tank can be confusing as each manufacturer offers a slightly different service and lead time. Please refer to our Delivery Information page. Standard tank deliveries are "kerbside" which means the tank will be delivered to the kerb only and not positioned further. Should you have specific delivery requirements or restrictions, please contact us to discuss.
Tanks Over 2500L – Articulated Lorry – Customer Offload:
These tanks will be delivered on an articulated vehicle (approximately 16.5m long x 2.6m wide x 3m high) which has no offloading on board, it is the customer's responsibility to offload the tank, which may require a telehandler / forklift. Curtain sided vehicles are also used, so please note that if there are obstacles or hanging branches on the road to the delivery site etc, the driver may refuse to drive the vehicle to the customer's location due to the possibility of damaging the vehicle. Please let us know if there are any obstructions before delivery, so we can arrange alternative transport.
18 Tonne Tail Lift HGV
This vehicle is the size of the largest bin lorries (for comparison) and is approximately 8.2m long x 2.6m wide x 4m high, often curtain sided so please note that if there are hanging branches etc, these vehicles will not attempt to drive down due to the possibility of damaging the vehicle and so it is recommended that a smaller vehicle is requested. Tanks will be lowered to the ground but not positioned as this is a kerbside delivery. If a smaller vehicle is required, please email us at sales@fueltankshop.co.uk quoting your order number and name.
HIAB Delivery
HIAB delivery is available but must be requested and there will be an additional cost for this service. If a HIAB delivery is required, please email us at sales@fueltankshop.co.uk quoting your order number and name, and we will come back to you with a price for this service.
Accessories:
Most accessories will be delivered within 1-3 working days (certain products and postcodes may take longer, please check the product page for update to date information). 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.
