What is Geothermal Energy?

Renewable energy you already own. And it's right in your backyard.

What is Geothermal Energy?

Geothermal Energy simply uses the earth as a heat exchanger to provide heating and cooling for your home year round. Depending on the location, the underground temperature remains between 50ºF - 55ºF. Geothermal Energy systems use the steady temperatures to pre warm refrigeration in the winter and pre cool refrigeration in the Summer.

How Does Geothermal Work?

The earth serves as a heat exchanger to pre-warm or pre-cool refrigeration. The refrigeration is compressed for heat and decompressed for A/C.  In the compressed state, liquid refrigeration reaches temperatures near 135 degrees F and travel through a large coil in the ductwork. The air moves over the coil producing discharge air temperatures at or above 100 degrees F. In the A/C mode, the refrigeration travels through the same coil with a temperature near 34 degrees F. The Summer time discharge air temperatures are dry and cool.

Geothermal Heating

To heat your home, geothermal systems capture heat from the earth through a closed loop water system that is pipe through your backyard. The heat is then transferred from the water to a closed loop refrigeration system located inside your basement. The geothermal system concentrates the heat by means of a compressor and circulates the warm refrigeration through a heat exchanger.  This heat exchanger can warm air to 100 degrees F and water to 130 degrees F.

Geothermal Cooling

In the summer the geothermal system reverses the cycle to provide air conditioning for your home. It does this by removing heat and humidity from inside your home and deposits it back underground.
