Geothermal Heat Pumps
Geothermal heat pumps are the most efficient heating and cooling systems available. They offer a single, simple system that uses the earth to heat and cool your home, and they operate at efficiencies of up to 500 percent.

Geothermal heat pumps are also environmentally friendly: You aren't creating heat, you're only moving it from one place to another.

How a Geothermal Heat Pump Works
The earth has a handy property that makes geothermal systems possible:
year-round temperature stability.

During the winter, when the earth is warmer than the air, heat is extracted from the ground and transferred to your home.

In the summer, when the earth is cooler than the air, the process reverts itself: Cool air from the ground is used to cool your home.

Flexible Options
Geothermal systems come in many styles to fit different needs and land space available. They can be a vertical loop system, horizontal loop system or slinky loop system as illustrated.
