Geothermal Heat Pumps: Good for the Bottom Line, Good for the Nation and Good for the Earth

Geothermal heat pumps (GHPs), also known as ground-source heat pumps, are similar to ordinary heat pumps, but use the thermally stable mass of the earth below the ground instead of outside air to provide heating, air conditioning and, in most cases hot water as well. Because these systems use the earth’s natural reservoir of stable temperatures, they are among the most efficient and comfortable heating and cooling technologies around. GHPs can save substantial amounts of energy and significantly reduce peak demand in buildings that incorporate them.
