A heat pump system for heating and cooling including a vapor compressor driven by a heat engine in which the refrigerant is isolated from a space being conditioned, by a two-pipe loop that, in a heating mode transfers both refrigeration derived heat and heat rejected by the heat engine in an efficient serial manner. The system circuitry includes a counterflow heat transfer fluid to air heat exchanger and a heat transfer fluid to potable water heater exchanger.
