Our Unvented Cylinders are made from high-strength duplex steel designed to operate at high pressure allowing for superior flow rates compared to a conventional cylinder. The tank can be placed anywhere in the property without the need for an expansion tank or gravity feed allowing for greater flexibility.

Our range of Stainless Steel Unvented cylinders are hand-crafted at our factory in the Newark, UK and can be designed to utilise a number of heat sources such as conventional Boilers, Electric Heaters, Heat Pumps and Solar Panels; we fit our units with a high surface area finned coil in varying sizes depending on their application.

Our Stainless units utilise a Monoblock Combined Pressure Reducing Valve and Expansion Valve for ease of installation and come complete with all required safety components. We offer a 10 Year Warranty against manufacturing defect. 

As all of our cylinders are made to order so can be further customised to your bespoke requirements. If you require further advice or have any unique requirements please get in touch on 01636 678437 or email us at sales@newarkcylinders.co.uk.

NOTE:

Installation should only be carried out by a “competant operative” i.e. the installer must have attended a recognised course in unvented hot water systems or recieved appropriate training in their apprenticeship. All registered operatives should carry an Indentification Card issued by the institute of Unvented Hot Water Systems.
