How Geothermal Works We all know that Lexington homes are acceptable to varying temperatures during the year. Some climates can see the extremities that summer and winter throw at us. There is a dependable source of temperature that you can utilize; just a few feet under the earth's surface. How is that possible? The sun permeates the Earth's crust with its heat energy. Forty-seven percent of that energy is cumulated in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; gathering this free heat for your home. This state-of-the-art technology uses the sun's heat that the earth has conveniently stored to condition your home or office. Geothermal Heating Using the earth loop, a WaterFurnace geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and delivers this warmed air through a traditional duct system. Additional choices include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling Cooling the air is just the reverse process used in the heating cycle. Warm air is driven by the geothermal heat pump into the ground. By removing the warm air, all that is left is cool air radiating throughout your home. There is no cost to heating your water during this process. For more information on how to get started with a geothermal system in the Lexington area, contact Arronco Comfort Air, Inc..
