What is Geothermal? - Residential Services - Commercial Services - Geothermal Photos

Geothermal is a technology that relies on the Earth's natural energy, which is a renewable resource, to heat or cool a home or building. Geothermal energy has been used as early as 10,000 years ago by the Romans.

The Earth's surface maintains a nearly constant temperature of 50 to 60°F. By using a geothermal pump system buried in the shallow ground, heat and cool air can be produced and sent into your home or building. A geothermal heat pump system consists of indoor heat pump equipment, a ground loop, and a flow center to connect the indoor and outdoor equipment. The heat pump equipment works like a reversible refrigerator by removing heat from one location and depositing it in another location. The ground loop, which is invisible after installation, allows the exchange of heat between the earth and the heat pump.

Geothermal energy is a huge, underused heat and power source that emits no greenhouse gases, is the most reliable, and is made right here in the United States.
