JAB DUC 2 90L Indirect Slim Unvented S/S Cylinder
The JAB DUC 2 90L Indirect Slim Unvented Stainless Steel Cylinder is a high-performance domestic hot water storage cylinder designed to deliver reliable, mains-pressure hot water to taps, showers, and appliances throughout the home.
Constructed from high-grade duplex stainless steel for durability and corrosion resistance, the DUC 2 90 provides long service life with minimal maintenance. Its compact 90-Litre capacity makes it ideal for smaller homes, apartments, and en-suite systems, while the unvented design eliminates the need for a cold-water storage tank - freeing up valuable loft space and providing powerful water pressure at every outlet.
This indirect model is designed to be heated by a gas or oil boiler, with an additional immersion heater connection for backup or off-peak heating.
Designed with installation in mind, allowing most existing airing cupboards to be used. The ideal choice for the replacement of standard copper cylinders.

JAB DUC 2 90L Indirect Slim Unvented 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.
