Geothermal Heat Pump (GHP) Systems

Geothermal heat pumps (sometimes referred to as GeoExchange, earth coupled, ground-source,
or water-source heat pumps) have been in use since the late 1940s.


Geothermal heat pumps (GHPs) use the constant temperature of the earth as the exchange medium instead of the outside air temperature. This allows the system to reach fairly high efficiencies (300%-600%) on the coldest of winter nights, compared to 175%-250% for air-source heat pumps on cool days.

While many parts of the country experience seasonal temperature extremes—from scorching heat in the summer to sub-zero cold in the winter—a few feet below the earth’s surface the ground remains at a relatively constant temperature. Depending on latitude, ground temperatures range from 45°F (7°C) to 75°F (21°C). Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. The GHP takes advantage of this by exchanging heat with the earth through a ground heat exchanger.

BENEFITS:

  • Lower operating costs: GHPs use 25%–50% less electricity than conventional heating or cooling systems, and no other fuel like natural gas or heating oil. According to the Enviornmental Protection Agency, geothermal heat pumps can reduce energy consumption—and corresponding emissions—up to 44% – compared to air-source heat pumps – and – up to 72% compared to electric resistance heating with standard air-conditioning equipment.
  • Enhanced comfort: GHPs improve humidity control by maintaining about 50% relative indoor humidity, making GHPs very effective in humid areas.
  • Environmentally Friendly: According to the Department of Energy and the EPA, geothermal systems are the most environmentally friendly way to heat and cool your home. GHP systems emit no carbon dioxide, carbon monoxide or other greenhouse gases. They are truly a natural, green heat pump.
  • Availability: Geothermal heat pump systems can be installed in both new and retrofit situations.
  • Reliability: Because GHP systems have relatively few moving parts, and because those parts are sheltered inside a building, they are durable and highly reliable. The underground piping often carries warranties of 25–50 years, and the heat pumps often last 20 years or more.
  • Security: Since they usually have no outdoor compressors, GHPs are not susceptible to vandalism.
  • Quiet: Because they have no outside condensing units like air conditioners, there’s no concern about noise outside the home. A two-speed GHP system is so quiet inside a house that users do not know it is operating: there are no tell-tale blasts of cold or hot air.
