Geothermal is defined as an electrically powered system that taps the stored energy of the earth. Geothermal systems use the earth’s relatively constant temperature to provide heating, cooling, and hot water for homes and commercial applications. Fluid is circulated through plastic pipes buried beneath the earth’s surface. During the winter, the fluid collects heat from the earth and carries it through the system and into the building. During the summer, the system reverses itself to cool the building by pulling heat from the building and carrying it through the system and placing it in the ground.
Benefits of using a geothermal system include:
- Safety: No open flame, flammable fuel or potentially dangerous fuel storage tanks
- There is also no external venting or air pollution created.
- The Department of Energy (DOE) and (EPA) have rated geothermal heating and cooling among the most energy efficient and environmentally friendly heating, cooling, and water heating systems available.
