The Earth is a giant solar collector that absorbs Solar Energy from the sun and stores it as Geothermal Energy. At depths of 30+ feet here in NJ, New Jersey this Geothermal heat energy is a constant 50+ degrees. We use this stored energy by drilling Geoexchange energy wells (we are also NJ licensed master well drillers) and installing a Geothermal heat pump to use this free solar powered Geothermal heating cooling energy. Open Loop Geothermal Heating, Cooling, Hot Water Systems use drilled GeoExchange supply and return ground water. energy wells. Closed Loop Geothermal systems use drilled Geoexchange energy wells with fluid filled U bend underground piping to transfer this free Solar Powered Geothermal Energy. Standing Column GeoExchange energy wells are a hybrid of open and closed loop using a single well in rock formations to transfer this free energy. So as the saying goes let's " Drill Baby, Drill " for the right reason.
