Geothermal is one of those renewable energy sources that promises to reduce our dependence on foreign oil and lower our carbon footprint. That usually means saving money, too, so there are many good reasons to consider geothermal air conditioning.
The technology takes advantage of shallow ground temperatures that are typically constant throughout the year and throughout the United States. The composition and location of your soil, rock and groundwater will have an impact on your heat transfer rates, and the installer of your geothermal heat pump will design a ground loop best suited to your specific situation. He or she will decide between a closed-loop and open-loop system, and a vertical or horizontal loop system.
Most common is the closed-loop system buried horizontally at four to six feet but, if space is limited, a vertical loop can be buried at 100 to 400 feet. The pipes typically are filled with an antifreeze-water mixture designed to extract heat from the earth and bring it into the house in the winter. In the summer it reverses the process, extracting heat from the house and depositing it in the cooler ground.
Typical annual energy savings range from 30 to 60 percent. The initial investment is higher than with traditional heat pumps but the experts say that cost will be recouped in energy savings within two to 10 years. Depending on the features that come with your geothermal heat pump, it might even use the heat it extracts from your house in the summertime to heat your water.
