Geothermal heat pumps provide the highest efficiency for space heating and cooling available today. The system transfers heat to and from the earth using only small amounts of electricity.
A geothermal heating and cooling system — also known as a ground-source heat pump — has by far the highest efficiency for the combination of space heating and cooling of any other system on the market today. The reason for this efficiency advantage is simple: geothermal systems do not consume fuel to produce heat. Instead, they capture some of the virtually limitless heat constantly available a few feet below the surface of the earth.
The typical geothermal system consists of a closed loop of special plastic tubing installed underground and an electrically powered compressor inside the home or other structure to be heated. An environmentally friendly, biodegradable antifreeze solution is circulated through the tubing.
A single system cleanly heats and cools your home at unmatched efficiency levels.
Because they use fewer mechanical components, and because those components are sheltered from the elements, geothermal heat pumps are durable and highly reliable.
Geothermal heat pumps use no outside condensing units, so there’s no noise or humming to bother either you or your neighbors.
For water heating, you can add a desuperheater to a geothermal system. A desuperheater is a small heat exchanger that takes heat from the unit's compressor to warm water. This hot water then circulates through a pipe to the home's storage water heater tank.
