If you’re searching for an energy-efficient heating option for your home, be sure to look into geothermal heat pumps. Geothermal heating has been used to heat homes for centuries and with advancing technology and an increasing emphasis on energy efficiency, this form of heating has now become more widely available.

How Do Geothermal Heat Pumps Work?

If you were to stick a thermometer into the soil six to 10 feet down, you’d find that the temperature there remains relatively consistent year-round, even during the hottest Savannah summer days. That temperature stability is the backbone of how a geothermal heat pump works.

Geothermal heat pumps use an extensive network of pipes laid several feet below ground. The heat pump circulates water or a water/refrigerant mixture through the pipes. During the warmer months, the pipe carries heat from inside your home and dispels it into the soil. During cold weather, it does the opposite, gathering the heat from the soil and using it to heat the air inside your home.

Using water via the underground pipes is 200 percent more efficient than using air to conduct heat.

Want to get a little extra out of your new geothermal system? Ask your HVAC professional if you can hook up your home’s water heaters to the geothermal system. They get hot water for little to no cost.
