How Geothermal Works

No matter what climate you live in, the temperature throughout the year varies. For some climatic zones that means blazing summers that cool to freezing winters, and Georgetown County is no exception. What many people don't realize is that the temperature underground (regardless of climate or season) stays fairly consistent all year.

The ground is able to maintain a higher rate of constant temperature because it absorbs 47% of the sun's energy (heat) as it hits the Earth's surface. WaterFurnace geothermal systems are able to draw from this free energy with an earth loop. This technology is then used to provide your home or office with central heating and cooling.

Geothermal Heating

During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system draws heat from the loop it circulates it through a traditional duct system as warm air. The same heat energy can also be put to use for a radiant floor system or household hot water heating.

Geothermal Cooling

During the cooling mode, cool, refreshing air is circulated throughout the house by reversing the heating process. Heat is not pulled, instead it is pushed into the ground. The warm heat is pulled from your home and taken back into the earth loop. Your hot water heating can be fueled by this procedure as well.
