Geothermal Heat Pumps (GHPs) are electrically powered systems that tap the stored energy of the greatest solar collector in existence: the earth. These systems use the earth’s relatively constant temperature to provide heating, cooling, and hot water for homes and commercial buildings.
A GHP system can be installed in a residential structure of any size, anywhere, whether it is single-family or multi-family. GHPs can be installed on almost any size lot: under lawns, landscaped areas, driveways, or the house itself. An existing house can be retrofitted with a GSHP using the ductwork that is already there. The new GHPs are much more efficient than the earlier models and upgrading to a new GHP can save money.
