How much space does a GHP unit require?
The majority of any GHP system is underground. Inside the building, the heat pump unit is much smaller than traditional heating and cooling units. The EarthLinked system is one-half the size of a water based unit because it does not require a water circulating pump and an intermediate heat exchanger. It is one-half the size of an air-source heat pump because it does not have an outside fan coil.
