Overview of Ground Source Heat Exchange System

The principle behind a ground source heat exchange system is basically no different than that which governs the operation of a refrigerator. The big difference between the two is, as its name implies, the inclusion of the ground. With the ground, we include in the system a source that is able to either absorb or donate a practically unlimited quantity of heat, if the system is appropriately sized.
As dictated by The Second Law of Dynamics, heat transfer occurs from hot to cold.
In the summer (when the house needs to be cooled off) excess heat is transferred from the house to the ground and in the winter (when the house needs to be heated up) heat is transfer from the ground to the house.
