A heating system for residential buildings is described in which heat is recovered by an auxiliary water heater. The heating system is of a heat pump type which includes a refrigerant fluid compressor and two heat exchanger units disposed in series connected relationship. The two heat exchanger units are those normally associated with respective fan and coil unit located within the interior of the residence and a condenser or evaporator located exteriorally of the building. A control valve is interposed in conduits connecting the two heat exchanger units with the compressor with this valve being selectively operable to control the system for operation in either a heating or a cooling mode. In accordance with this invention, an auxiliary water heater is interposed in heat recovery relationship to the heating system and includes a heat exchanger that is interconnected in the refrigerant fluid conduit. The auxiliary water heater has a heat exchanger that is interconnected in the conduit intermediate the compressor and the control valve. The water heater is thus able to recover excess heat regardless of whether the heating system is operating in a heating or cooling mode.
