Geothermal Energy

The word Geothermal is derived from the Greek words geo (earth) and therme (heat). Hence, energy generated by heat stored beneath the earth's surface. Geothermal systems use the earth's constant temperature to provide heating, cooling, and hot water for homes, commercial buildings, and schools. Best of all, it is a renewable energy source.

Geothermal systems can even be used in new or retrofit applications.

The U.S. Environmental Protection Agency has come to the conclusion that well designed and properly installed heat pump systems produce less environmental harm than any other source of heating and cooling technology currently available.

Closed Loop systems can be installed in three ways:

  • vertical
  • horizontal
  • pond or lake

The type chosen depends on the amount of land available, as well as soil and rock conditions on the job site.

Closed looped systems circulate water and propylene glycol (R.V. Antifreeze) through High Density Polyethlyene (HDPE) pipes buried in the ground either vertically or horizontally. During the winter, the fluid collects heat from the earth and circulates it through the system and into the building through the ground source heat pump. In the summertime, the system pulls heat from the building, carrying it through the system placing it in the ground. This also creates free hot water in the summer and substancial savings for hot water in the winter.
