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.
Thus heat is also described as a degraded form of energy. There is one interesting (though not hugely efficient) process in this context called a ground-source heat pump which uses the ambient heat of damp (or wet) soil to power domestic heating systems.
