Geothermal Heat Pumps (GHP)

What is a GHP?

Geothermal heat pumps are heating and cooling systems that use the relatively constant temperature of the earth as the exchange medium instead of the outside air temperature. They have been in use since the late 1940s and are sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps.

The ground temperature a few feet below the earth’s surface remains at a relatively constant temperature, depending on latitude, ranging from 45°F to 75°F. GHPs take advantage of these more favorable temperatures to become highly efficient by exchanging heat with the earth through a ground heat exchanger.

Benefits of a GHP

GHP’s are highly efficient, quiet, and long-lasting. They are able to heat, cool, and supply hot water to homes, and some models are available with two-speed compressors and variable fans for more comfort and energy savings. Compared to air-source heat pumps, GHPs last longer, need less maintenance, and do not depend on the temperature of the outside air.

Although the installation price of a GHP can be several times that of an air-source system of the same capacity, the additional costs may be recouped in energy savings in 5 to 10 years, depending on the cost of energy and available incentives in your area. The system life is estimated at up to 24 years for the inside components and 50+ years for the ground loop.

A dual-source heat pump, which combines an air-source heat pump with a geothermal heat pump, can be a cost-effective alternative to a single geothermal unit, with higher efficiency ratings than air-source units and almost as good performance.
