What Is The Difference Between Geoexchange System And A Conventional HVAC System?

Geoexchange systems are different from all other HVAC systems due to their ability to store thermal energy: the ground loop essentially acts as a “thermal battery”. Heat rejected from a building during summer air conditioning is stored in the earth surrounding the ground loop, and is reclaimed during the heating season. The ability to store and reclaim thermal energy greatly increases geoexchange efficiency when compared to air source heat pumps.

Geoexchange systems don’t rely on fossil fuel combustion to produce heat. Instead the ground source heat pump simply concentrates and transfers heat that is already there. This process of moving heat uses far less energy than conventional methods.
