How Geothermal Works We all know that Knox County homes are acceptable to varying temperatures throughout the year. Some climates can see the extremes that summer and winter hit us with. There is a dependable source of temperature that you can utilize; just a few feet underneath the earth's surface. How is that possible? The sun imparts the Earth's crust with its heat energy. Forty-seven percent of that energy is stockpiled in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; harvesting this free heat for your home. This innovative technology uses the sun's heat that the earth has readily stored to condition your home or office. Geothermal Heating Utilizing the earth loop, a WaterFurnace geothermal heat pump extracts the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and passes this warmed air through a conventional duct system. Additional choices include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling During the cooling mode, cold, conditioned air is circulated throughout 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 Knox County area, contact Cosby Heating and Cooling.
