Abstract
A combination domestic hot water and space heating system is disclosed. The system includes two refrigerant circuits, one dedicated to heating potable water in a water storage tank and one dedicated to heating a condenser used to heat a space within a building. A controller sends output signals to valves to vary refrigerant flow into the first refrigerant circuit and/or the second refrigerant circuit. The variation in refrigerant flow can be provided by a single multi-directional valve, one or more valves placed at a first end of each refrigerant circuit, and/or one or more electronic expansion valves placed at the end of each refrigerant circuit. Portions of the system can be placed into a single housing, thereby reducing installation costs and labor.
