With ground coupled systems water is taken from the ground or surface water (pond, lake, etc.), circulated to the individual heat pumps and the returned to the ground. With refrigerant loop systems a refrigerant such as R-22 is substituted for the water.
The COP for heat pumps range from 3.2 to 4.5 for air source heat pumps to 4.2 to 5.2 for ground source heat pumps. When used for heating a building with an outside temperature of, for example, 10 Â°C, a typical air-source heat pump (ASHP) has a COP of 3 to 4, whereas an electrical resistance heater has a COP of 1.0.
