Year-round in this area, the ground stays at about 50 degrees Fahrenheit. Geothermal systems warm or cool water (depending on the air temperature) in underground loops. The heat from this warmed or cooled water is transferred to the heat pump where it is compressed or decompressed to concentrate the effect. This hot air heat or air conditioning is then sent throughout your home. This technology is available ANYWHERE even in areas where bedrock is close to the surface.
A geothermal heat pump or ground source heat pump (GSHP) is a central heating and/or cooling system that transfers heat to or from the ground. It uses the earth as a heat source (in the winter) or a heat sink (in the summer).
The ground source heat pump (GSHP) system can be installed in a residential structure of any size, anywhere, whether it is single-family or multi-family. GSHPs can be installed on almost any size lot: under lawns, landscaped areas, driveways, or the house itself. An existing house can be retrofitted with a GSHP using the duct work that is already there.
The Department of Energy (DOE) and the Environmental Protection Agency (EPA) have both endorsed ground source heat pump systems as among the most energy efficient and environmentally friendly heating, cooling, and water heating systems available. In a 1993 report, the EPA concluded that geothermal technologies represent a major opportunity for reducing national energy use and pollution, while delivering comfort, reliability and savings to homeowners.
Ground source heat pumps (GSHP)s are a cost effective, energy efficient, and environmentally friendly way of heating and cooling buildings. Both the DOE and the EPA have endorsed the technology. GSHPs reliably deliver quality air-conditioning and heating, on demand, in every season. GSHPs are appropriate for new construction as well as retrofits of older buildings. [Nobel Research Center] Their flexible design requirements make them a good choice for schools, high-rises, government buildings, apartments, and restaurants--almost any commercial property. Lower operating and maintenance costs, durability, and energy conservation make Ground Source Heat Pumps the smart choice for commercial applications.
