Stew I know you had expressed some interest in this! (ground source heating). This other option is known as the Reverse Cycle Chiller But here is a heat pump option that uses Heat pump technology at a much higher Eff. curve to well below zero. As quoted: (The RCC system also allows the heat pump to operate at peak efficiency even at low temperatures. This provides greater comfort and economy without the need for electric resistance auxiliary heating coils. For example, in one Michigan installation, the RCC system supplied 115°F (46°C) water to the air handler and a radiant floor system even though the outdoor temperature was negative 15°F (-9.4°C). ) This will Heat AND Cool and supply your hot water as well for the house. As Quoted again: In the summer it makes free hot water by reclaiming the waste heat from the house as long as the system is also cooling the building. ) Google it and happy reading .
