How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can range from blazing summers to cold winters; Greater Cincinnati included. Did you know there is a fairly consistent temperature, regardless of climate or season, just below the ground? The Earth's crust takes in 47% of the sun's heat (energy) and is sustained in the ground a few feet below the surface. Our geothermal systems draw from this free resource with an earth loop. This creative technology salvages the sun's heat providing your home or office with central heating and cooling. Geothermal Heating During the heating cycle, a geothermal heat pump uses the earth loop to extract heat from the ground. As the system draws heat from the loop it distributes it through a conventional 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 In the cooling mode, the heating process is reversed - creating cool, conditioned air all through the home. Instead of extracting heat from the ground, heat is taken 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.
