A geothermal heat pump (GHP) is a heating and cooling system that takes advantage of the relatively stable moderate temperature conditions within the first 300 meters (1,000 feet) below the surface of the Earth to heat a building in the winter and cool it in the summer. Unlike boilers or furnaces, GHPs do not rely on the combustion of fossil fuels to produce heat, and thus they produce no direct emissions of greenhouse gases.
