Geothermal systems are rated number one in energy efficiency because they can deliver more than five units of energy for every one unit of electrical energy used. Compare that to even the best ordinary system that delivers less than one unit of energy for every unit it consumes. That translates into an efficiency rating exceeding 530%, compared to the most efficient gas furnace which rates only 98%.

Most homeowners save more on monthly bills than they pay for the system when installation costs are financed. Any added investment over traditional equipment is usually recovered in just a few years, and many homeowners see a return on investment of 10-20% over the life of the system. A ground source heat pump is the only heating and cooling technology that pays you back.

Geothermal systems are recognized by the United States Environmental Protection Agency as the most environmentally friendly, cost effective and energy efficient heating and cooling technology available. These systems also minimize the threats of acid rain, air pollution, the greenhouse effect and global warming—problems directly linked to the burning of fossil fuels. In fact, installing a single geothermal unit is the environmental equivalent of planting 750 trees.

In addition to the federal tax credit, some state, local, and utility incentives may be available in your area for even more savings on installing a geothermal heat pump. Check out the Database of State Incentives for Renewables & Efficiency website to find policies and incentives in your area.
