This invention pertains to a heat exchange system having a space heating, a space cooling and an independent water heating cycle. During the space heating and space cooling cycles a refrigerant is used to transfer heat by circulating between a condenser/evaporator and a heat exchanger, the refrigerant being evaporated and condensed in the process. During the independent water heating cycle a third heat exchanger is used to condense the refrigerant. The heat removed by this exchanger is used for the evaporating of the refrigerant. A fourth heat exchanger is provided for water heating. Either water pumped from an outside source or outside air may be used as a heat source and sink.

A heat exchange system having a space heating cycle, a space cooling cycle with water heating, and an independent water heating cycle comprising: a compressor; a refrigerant adapted to absorb and emit heat by changing from a liquid to a gas and from a gas to a liquid phase respectively circulated by said compressor; a medium adapted to absorb or emit heat; a water storage tank; a first transfer means for transferring heat for space heating from said refrigerant during the heating cycle and for transferring heat to said refrigerant for space cooling during the cooling cycle; a second transfer means for transferring heat from said medium to said refrigerant during the space heating cycle and independent water heating cycle and for transferring heat to said medium from said refrigerant during said space cooling; a third transfer means for transferring excess heat during the independent water heating cycle from said refrigerant to said medium; to condense said refrigerant; a fourth transfer means for transferring heat from said refrigerant to a water storage tank; a piping means operatively connected to allow the flow of said refrigerant between said compressor, and said transfer means; and a control means for controlling said flow; whereby during the heating cycle heat is transmitted by the refrigerant form said medium to said first transfer means; whereby during the cooling cycle heat is transmitted by the refrigerant from said first transfer means to said medium; and whereby during the independent water heating cycle heat for water heating is transmitted from said medium to said tank.
