Hot water connection:
2.28
Hot water cylinder or storage tank: When a hot water cylinder or storage tank
is used, ensure the pipework size from the cold water storage to the hot water
storage is of adequate size and a minimum of 22 mm.
2.29 Hot water supply: The pump must be supplied with a dedicated feed direct
from the hot water cylinder or storage tank, ensuring an air free connection to the
cylinder, which can be made by one of the methods shown in Fig. 5. We
recommend the use of the Techflow top flange Part No 27901.
2.30 Expansion pipe: When the method of connection is to be made via the
expansion pipe, the BASE of the cold water storage tank MUST be at least
1 metre above the connection/take off of the hot water storage cylinder feeding
the pump.
2.31 Location: The pump must, for optimum performance, be sited as close as
possible to and never more than 4 metres from the HOT WATER cylinder. The
pump should always be sited BELOW the HOT WATER take-off from the cylinder.
