Geothermal energy has been used to heat and cool buildings for many decades. During that time, these geothermal systems have been called many things: geoexchange, geothermal, ground-water, ground-water-source, water-to-water, and even water furnace heating and cooling.
A geothermal heat pump uses the earth to warm us in the winter and cool us in the summer.
All of these terms, convey the same thought: use of geothermal heat pump technology to tap the energy in the earth’s surface and drive a heating and air conditioning system for both residential and commercial uses. The result is a green or natural heat pump that saves energy and benefits the environment.
