A Ground Coupled Heat Pump System (GCHP) is a heat pump with or without any thermal storage which uses soil as a heat source or sink. Soil, due to its large thermal capacity and inertia, can serve as a heat source or sink, thus offering relatively constant operation conditions for a heat pump. The soil temperature at a depth of about 2.0m fluctuates slightly around the yearly average air temperature at any given location. This offers a lower and stable sink temperature in the cooling mode operation and a higher and stable source temperature in the heating mode operation. The major consequence of this fact for a GCHP operation is a lower energy consumption as compared with a standard air-source heat pump.
