Geothermal by TTHERMGEO

Geothermal heating and cooling systems take advantage of the earth's ability to store heat. Water circulates through a loop of pipe buried in the ground and draws off the free heat from the earth. The heat is then concentrated by the TTHERMGEO geothermal heat pump through the refrigeration process and is released into your home through the blower or radiant floor heat system. In the summer, the process is reversed and heat is removed from your home and put back into the earth. Watch how it works
