Geothermal heat pumps use the earth’s natural heat to circulate water or refrigerant between an underground network of pipes and heat pumps located inside the house. Although geothermal heat pumps are similar to ordinary heat pumps, they only differ in their usage of the ground instead of outside air to provide heating and air conditioning. The principle behind geothermal heat pumps is that in winters, the pumps move the heat from the earth into your house and in summers, the devices pull heat from your home and discharge it into the ground.
As geothermal heat pumps mostly use renewable energy from the ground, these heat pumps are among the most efficient and comfortable heating and cooling technology. Although geothermal heat pumps are costlier to install than regular heat pumps, the U.S. Environmental Protection Agency estimated that geothermal heat pumps can also lower energy bills by 30 to 40 percent. Additionally, geothermal heat pumps are mechanically simple and most of their parts remain below the ground and are protected from the weather, thus reducing maintenance costs as well. Geothermal heat pumps are also included in the types of products rated in the EnergyStar program by the U.S. Environmental Protection Agency for being an environmentally friendly invention.
Geothermal heat pumps are durable, comfortable, environmentally safe, non-allergenic and clean. Such heat pumps not only lower your heating and cooling bills, but also require minimal maintenance. Geothermal heat pumps provide the utmost comfort by heating and cooling in an even fashion and eliminating hot and cold spots. Such heat pumps are also environmentally safe, as they minimize environmental threats posed by the burning of fossil fuels, like acid rain, air pollution, and the greenhouse effect.
