A geothermal heat pump system is a heating and cooling system that provides heat in winter and cooling in summer, at efficiencies that are far better than those for alternative systems. Like a conventional heat pump, it is essentially an air conditioner that can also run in reverse to provide heat in the winter. The primary difference is that it relies on the nearly constant temperature of the ground or groundwater for heat transfer instead of the widely fluctuating temperature of the outside air. As a result, a geothermal heat pump system saves energy, cuts electric bills, reduces greenhouse gas emissions, and offers lower maintenance and lower hot water costs than conventional heating and cooling.

NGWA promoted federal tax incentives to encourage geothermal heat pump use, increase our nation's energy efficiency, and provide business opportunities for our membership.
