Geothermal energy is an unlimited resource. The lot surrounding a suburban home or other building contains
a vast reservoir of low temperature thermal energy, typically 10 times that required over an entire heating season. This resource is constantly resupplied by the sun, the surrounding earth, and heat rejected while cooling during the summer. The universal definition of geothermal is “…pertaining to the heat of the earth.” By using the earth to provide up to 50% of a building’s total heating and cooling needs, GHP systems are truly geothermal energy made practical.
