New Geothermal Heating and Cooling Technology


EarthSpar, A New Paradigm for Geothermal Heat Pumps

According to the U.S. Environmental Protection Agency, ground source heat pumps (GSHP) are the most efficient heating and cooling systems.  The patent pending EarthSpar™, an innovative heat transfer device and insertion system is being developed that reduces the cost of GSHP ground loops by half. This new concept removes a significant barrier in the residential geothermal heating and cooling marketplace, the high cost of installing the earth coupled heat exchanger.

The direct insertion ground loop heat exchanger is a novel device that holds the promise of providing geothermal systems to many more homes and businesses, thereby reducing energy costs dramatically. The U.S. Department of Energy awarded Promethient a “proof of concept” grant to validate this new concept.
