How Geothermal Works The temperature throughout the year will always vary no matter what climate you live in. For some climatic zones that means blazing summers that cool to frigid winters, and Columbus 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 maintain a higher rate of constant temperature because it takes in 47% of the sun's energy (heat) as it impacts 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 equip your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump utilizes the earth loop system to extract the heat from the ground. With delivery through a standard duct system, the geothermal system draws heat from the loops and circulates it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling The heating process is reversed in the cooling mode - creating cool, conditioned air throughout the home. Instead of pulling heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
