Geothermal Annual Operating Costs

Geothermal Annual Operating Costs

If you’re exploring geothermal systems for the first time, you might wonder how the operating costs compare to other heating and cooling systems. For example, how do they stack up against existing air source heat pump (ASHP) systems? What about existing propane furnaces with air conditioning systems? To gauge how much you might save by switching to a geothermal system, check out the comparison below.

This comparison is based on a ranch-style home with 2,400 square feet of living space and all brick over an uninsulated crawl space. The attic features R-38 insulation, the front of the home faces north, and the garage resides on the west side of the home. As you scroll down, you will see the load calculation followed by three examples.
