The return flow domestic hot water heat pump is designed for a 2-3 people household.
The return flow domestic hot water heat pump is a water/water heat pump that extracts thermal energy from the return flow of a floor heating system. The pump of the domestic hot water heat pump extracts the required amount of water from the heating circuit for heat generation. It is not necessary to switch off the heating in summer.
