Geothermal Heat Pumps

Geothermal heat pumps are similar to ordinary air source heat pumps, but use the ground instead of outside air to provide heating, air conditioning and, in most cases, hot water. Because they use the earth's natural heat, they are among the most efficient and comfortable heating and cooling technologies currently available.

Why get a geothermal heat?

Geothermal heat pumps have been used since the late 1940's. Instead of using the outside air temperature as the exchange, geothermal heat pumps use the constant temperature of the earth to heat and cool the inside of the home. Temperatures below the surface are much like those you would find in a cave; the air is warmer than the air above in the winter and cooler than the air in the summer. The high efficiencies of the geothermal heat pumps are what make them so appealing to homeowners, in addition to fact that they last longer, need little maintenance, are quieter, and do not depend on the temperature of the outside air.

The price to install a geothermal heating and cooling system can be several times that of an air-source heat pump, but in 5 to 10 years you will see the return of those additional costs from your energy savings.  A geothermal heating and cooling system is estimated at 235 years for the inside components and 50 or more years for the round loop.

For a more cost effective option, a dual-source heat pump may be a good option.  This combines the geothermal heat pump with the air-source heat pump.
