Product Code
U02400
If continuous flow water heaters are used on circulation systems an unvented system kit is required to allow for expansion of the hot water system. The kit includes the necessary safety devices required to confirm to the current building regulations.

Three sizes of kit can be supplied and each contains a combined strainer/pressure reducing valve set to 3.5 bar, check valve, expansion valve set to 6.0 bar, tundish, 5 litre expansion vessel, wall bracket and hose.

When the circulation system includes a storage cylinder/buffer vessel, a combined temperature/pressure relief valve must be sized to suit the total input of all the water heaters installed on the system (see table above right). This must be located on the storage unit. In addition the size of the expansion vessel must also be increased to suit both the storage cylinder plus the contents of the system pipework (see vessel table).
