A heating and cooling system with a single compressor and first and second compressor reversing valves for connecting a refrigerant fluid to more than one heat exchanger in a system. Said second compressor reversing valve permits the compressor to function as the primary compressor for different operating modes. A reversible heat pump means is operably connected to a plurality of heat exchange devices in indirect heat exchange with external thermal storage media common to the home such as room airspace, domestic hot water and pool or spa. Combinations of heating and cooling of the various external thermal storage media are realized by arranging valving and conduit means using appropriate control and switching apparatus.
