How Geothermal Works

The temperature throughout the year will always vary no matter what climate you live in. For some climatic zones that means hot summers that cool to ice-cold winters, and Chillicothe is no exception. What most people don't realize is that the temperature underground (regardless of climate or season) stays pretty consistent year round.

The ground is able to sustain 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 extract 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 draw heat from the ground. As the system pulls heat from the loop it distributes it through a standard 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, cold, refreshing air is circulated through the house by doing the exact opposite as the heating process. Heat is not extracted, instead it is pushed into the ground. The warm heat is pulled from your home and transferred back into the earth loop. Your hot water heating can be fueled by this technique as well.
