Not all renewable energy resources come from the sun. Geothermal energy taps the Earth's internal heat for a variety of uses, including electric power production and the heating and cooling of buildings. VP Supply's Geothermal HVAC products utilize ambient ground temperature to regulate water system temperatures.  Producing dramatic efficiency results for home heating and cooling.


Tax Incentives: 30% (of total system cost) tax credit on Federal Income Tax (no cap, must meet Tax Incentives: Energy Star requirements)
ROI: About 3 to 5 years
Energy Efficiency: 3.5 to 5 times as efficient as the most efficient fossil fuel furnace
Ideal Location: Basement, garage, or utility room
Size: Can fit in most residential yards
New vs. Remodel: Works well in both situations with a relatively low payback period

How it Works

A geothermal or "ground-source" heat pump is an electrically powered device that uses the natural heat storage ability of the earth and/or the earth's groundwater to heat and cool your home or business.

Different Loops

Geothermal or ground source heat pumps can be categorized as having closed or open loops. Those loops can be installed in a variety of ways: horizontally, vertically, or in a pond/lake. The type chosen depends on the available land areas and the soil and rock type at the installation site.

  • Closed Loop describes a geothermal heat pump system that uses a continuous loop of special buried plastic pipe as a heat exchanger. Unlike an Open Loop system that consumes water from a well, a Closed Loop system recirculates its heat transferring solution in pressurized pipe.

  • Open Loop describes a geothermal heat pump system that uses groundwater from a conventional well as a heat source in winter and a heat sink in summer.

Benefits of Geothermal

  • Can cut energy consumption by 20 to 50% and reduce maintenance costs

  • Heating efficiencies 50 to 70% higher than other heating systems and cooling efficiencies 20 to 40% higher than available air conditioners

  • Uses underground loops to transfer heat, with no external venting and no air pollution

  • Keep the air warmer in the winter (90 -105 degrees Farenheit) and at a more consistent temperature throughout the home, eliminating the hot and cold spots common with other systems

  • Conserve natural resources by providing climate control efficiently and thus lowering emissions

  • No exposed equipment outdoors; children or pets cannot injure themselves or damage exterior units
