WebJul 14, 2008 · Ground-source heat pumps. A much more conventional way to tap geothermal energy is by using geothermal heat pumps to provide heat and cooling to buildings. Also called ground-source heat pumps, they take advantage of the constant year-round temperature of about 50°F that is just a few feet below the ground’s surface. WebMar 6, 2024 · Installing a ground source heat pump is a large project , so you might expect to pay between $10,000 - $30,000 on a system. For smaller homes with lower heating and cooling loads, expect to be on the lower end of this spectrum. For example, a 2,000 square foot home will cost between $3,000 to $5,000 to install. WebGeothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s. They use the relatively constant temperature of the earth as the exchange medium instead of the outside air temperature. free horizontal banner templates
