A GSHP is the highest efficiency heating and cooling system available because it uses a renewable energy source: the earth. This system is three times more efficient than the highest efficiency gas furnace and consists of a network of durable plastic coils buried in the ground that absorb the earth’s heat energy.

A heat pump, which is connected to the coils, extracts that energy and converts it into heat, which is then transferred into the home. At the flip of a switch, the process can be reversed to cool in the summer. GSHPs are long-lasting, low-maintenance systems designed to meet 100 percent of a home’s heating and cooling needs. WH does not sell or install GSHPs.
