How Geothermal Works As the seasons move from spring to winter, temperature fluctuates throughout the year. Some climates can vary from sweltering summers to frigid winters; Lime Springs included. Did you know there is a fairly 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 maintained in the ground a few feet below the surface. WaterFurnace geothermal systems extract this free heat with an earth loop. This creative technology reclaims the sun's heat providing 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 traditional 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 extracted from your home and transferred back into the earth loop. Your hot water heating can be fueled by this technique as well. For more information on how to get started with a geothermal system in the Lime Springs area, contact Johnson Comfort Systems, Inc..
