Ground Source Heat Pumps
One thing that makes a geothermal heat pump so versatile is its ability to be a heating and
cooling system in one. With a simple flick of a switch on your indoor thermostat, you can
change from one mode to another. In the cooling mode, a geothermal heat pump...
Geoexchange
The term 'geoexchange' is being increasingly adopted worldwide as systems that operate through a heat exchange process with stable temperatures located at depths of just a few meters below the surface of the ground or a water body...
Geothermal Heating and Cooling
Geothermal heating and cooling systems do not create heat, rather they move it from one area to another with the aid of electricity to operate the pump. Within the building, there is a heat-exchanger and the warmed (or cooled) air is circulated...
Direct Exchange (DX) Geothermal Heat Pumps
In direct exchange (DX) geothermal heating and cooling systems refrigerant circulates through underground copper tubing so the heat exchange is immediate and super efficient...
Concerns about Copper in DX Geothermal Systems
IA common concern about Direct Exchange (DX) geothermal systems is that the copper tubing may corrode and leak refrigerant into the soil creating an environmental hazard...
Geothermal Heat Pump Retrofits
Geothermal retrofits often work well, especially if it is replacing a furnace that fits into existing ductwork. Government rebates for retrofits make the option more attractive...
Geothermal Heat Pump Equipment
While the basic principles of geothermal heating with ground source heat pumps haven't changed much in 50 years, the technology has, with radically improved efficiency and functionality...

Geothermal Manufacturers Converting to Chlorine-free Refrigerants
For years, the refrigerant of choice has been R-22, also known as HCFC-22 (short for hydrochlorofluorocarbon) or Freon 22. But R-22, when released into the atmosphere...
Geothermal Ground Source Heat Pumps vs. Air to Air
Is a ground source heat pump more efficient than an air to air heat pump? A ground-source heat pump, with its underground piping loop, is able to tap a warmer, more stable heat source...
