How Geothermal Works As the seasons change from spring to winter, temperature varies throughout the year. Some climates can vary from sweltering summers to frigid winters; Columbus included. Did you know there is a fairly consistent temperature, regardless of climate or season, just below the ground? The Earth's crust absorbs 47% of the sun's heat (energy) and is maintained in the ground a few feet underneath the surface. Our geothermal systems draw from this free resource with an earth loop. This inventive technology reclaims the sun's heat supplying your home or office with central heating and cooling. Geothermal Heating During the heating cycle, a geothermal heat pump uses the earth loop to draw heat from the ground. As the system draws heat from the loop it distributes 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 During the cooling mode, cool, conditioned air is distributed 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 transferred back into the earth loop. Your hot water heating can be fueled by this process as well.
