Residential Benefits

In addition to the general benefits of a geothermal system, there are other advantages to the homeowner installing a geothermal heat pump system.

Efficiency
In the heating mode the geothermal heat pump system extracts two-thirds or more of its energy from the earth and moves it to the heat pump unit. Only one-third of the energy needed is purchased power. This is used to run the compressor, circulating pump and fan.

In the cooling mode, the unwanted heat is transferred back into the earth for reuse in winter.

No Outdoor Equipment
All of the equipment needed can be installed in a closet, garage, or attic. There is no visible outdoor unit to suffer from deterioration due to weather or vandalism...and no outdoor noise!

The rest of the equipment consists of an array of piping buried beneath the ground. These pipes can be installed in a vertical well system, horizontally buried under the surface, or installed in a pond. In some cases, well or pond water can be used directly without buried pipe.

Environmental
Geothermal heat pump systems produce no on-site pollutants, improve indoor air quality, and reduce the amount of pollutants at the generating station when compared to other forms of electric heat. They also result in lower carbon dioxide emissions which reduces the threat of global warming.

Domestic Hot Water
In summer, the unwanted heat can be used to preheat your hot water at a very low operating cost. In winter, surplus heat can be used in the same way.

Warmer Air Distributed in Winter
No more seemingly cold drafts from the air outlets often encountered with conventional heat pumps.

No Supplemental Heat
Most geothermal systems can operate year-round without supplemental resistance heat.

Little or No Out-of-Pocket Incremental Cost
Any added initial cost can often be included in the mortgage financing, and the operating cost savings used to amortize the added investment, if any.
