We can provide both vented and unvented cylinder options which can be incorporated into a full heating design or as a stand alone installation or replacement.


The traditional British hot water supply system, in which water is heated and stored for use, is based on cold water feed from a storage water tank, normally in the loft space, to a heated cylinder that is vented to the atmosphere. The flow rate and pressure of the hot water outlets is then dependant on the height of the storage tank above the outlets.
