2 General Description
If water is not tapped for longer periods of time, the water in the hot water pipe cools
off. Domestic hot water pumps (also called sanitary or drinking water circulation
pumps) pump this cold water back into the water heater via a separate circulation
pipe. The water that then flows out of the water heater provides a constant supply
of hot water at the tap (increased comfort). At the same time, drinking water is
conserved. Drinking water circulation pumps S1 + E1 are suitable for single- and
two-family homes with a circulation pipe length of approx. 50 m. The version at
hand can be determined from the type designation:
