How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can range from sweltering summers to frigid winters; Topeka included. Did you know there is a pretty constant 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. WaterFurnace geothermal systems tap into this free heat source with an earth loop. This inventive technology recovers the sun's heat supplying 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 draw the heat from the ground. With delivery through a traditional duct system, the geothermal system pulls heat from the loops and distributes 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 taken back into the earth loop. Your hot water heating can be fueled by this procedure as well. For more information on how to get started with a geothermal system in the Topeka area, contact Ground Source, Inc..
