Geothermal heating tends to be the most efficient way to heat a house when compared to traditional HVAC systems, according to the U.S. Department of Energy. Geothermal heat pumps (also called ground-source heat pumps) transfer energy to and from the ground to supply heat, cool air and hot water.
Note that one of the most important ways to boost efficiency, save electricity and lower your heating bills is to make sure your house is weather-tight and well-insulated.
