How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can range from fiery summers to ice-cold winters; Dallas included. Did you know there is a pretty constant 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 retained in the ground a few feet beneath the surface. Our geothermal systems draw from this free heat source with an earth loop. This creative technology recovers the sun's heat supplying your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a geothermal heat pump employs 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. Options are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling During the cooling mode, cold, refreshing air is circulated through the house by doing the exact opposite as the heating process. Heat is not extracted, instead it is propelled 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. For more information on how to get started with a geothermal system in the Dallas area, contact Geo-Thermal Distribution Co., LLC.
