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 frigid winters, and Greenville is no exception. What many people don't realize is that the temperature below ground (regardless of climate or season) stays pretty consistent year round. The ground is able to sustain a higher rate of temperature consistency because it takes in 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 put to use to provide your home or office with central heating and cooling. Geothermal Heating Using the earth loop, a WaterFurnace geothermal heat pump takes the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and passes this warmed air through a traditional duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling During the cooling mode, cool, refreshing air is distributed throughout the house by doing the exact opposite as the heating process. Heat is not pulled, instead it is driven into the ground. The warm heat is extracted from your home and taken back into the earth loop. Your hot water heating can be fueled by this procedure as well.
