Unvented Cylinder

(116 products)

A pressurised system, an unvented hot water cylinder is fed directly from the cold mains water feed which eliminates the need for a cold water tank in the loft. Because it relies on mains pressure rather than gravity, it can be situated almost anywhere and means the performance is great. It is vitally important the an unvented cylinder is installed by an accredited installer and serviced on an annual basis to ensure that it is safe and that the expansion vessel and relief valves are functioning correctly.
