Geothermal systems cost more than conventional systems due to the cost of installing the ground loop (or pond loop). However, the life-cycle cost of a geothermal system is competitive with conventional systems due to energy savings over the life of the system. For more specific costs, consult an IGA member in your area.

The U.S. Department of Energy explains: ‘The heating efficiency of ground-source and water-source heat pumps is indicated by their coefficient of performance (COP), which is the ratio of heat provided in Btu per Btu of energy input. Their cooling efficiency is indicated by the Energy Efficiency Ratio (EER), which is the ratio of the heat removed (in Btu per hour) to the electricity required (in watts) to run the unit. Look for the ENERGY STAR® label, which indicates a heating COP of 3.3 or greater and an EER of 14.1 or greater.’
These ENERGY STAR® efficiencies compare favorably to a COP of 1.0 for resistance heaters and an EER of 10.0-11.0 for central air conditioners.
Geothermal Systems will offer energy savings that can often pay for the increased investment in 2 – 15 years.
