Geothermal Energy is heat derived from the earth. It is the thermal energy contained in the rock and fluid that fill up the fractures and pores in the earth's crust. The temperature 10 feet below the ground remains constant, between 50° and 60°F.


The soil temperatures are usually warmer than the air in winter and cooler in summer. The earth's constant temperature combined with pressurization or condensation is used for heating and cooling buildings. The geothermal pump transfers heat from the ground or water to the building in winter and vice versa during summer.
