How Geothermal Works We all know that Columbus homes are subjected to varying temperatures throughout the year. Some climates can see the extremes that summer and winter hit us with. There is a dependable source of temperature that you can put to good use; just a few feet under the earth's surface. How is that possible? The sun instills the Earth's crust with its heat energy. Forty-seven percent of that energy is stockpiled in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; gathering this free heat for your home. This cutting-edge technology uses the sun's heat that the earth has conveniently accumulated to condition your home or office. Geothermal Heating During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it circulates it through a standard duct system as warm air. The same heat energy can also be used for a radiant floor system or household hot water heating. Geothermal Cooling Cooling the air is just the reverse process used in the heating cycle. Warm air is pushed by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air circulating throughout your home. Heating your water during this process is "free".
