How Geothermal Works We all know that Kearney homes are subjected to varying temperatures throughout the year. Some climates can see the extremes that summer and winter throw at us. 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 tap this heating potential using an earth loop system; collecting this free heat for your home. This cutting-edge technology uses the sun's heat that the earth has readily deposited to condition your home or office. Geothermal Heating During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a standard duct system as warm air. The same heat energy can also be utilized for a radiant floor system or domestic hot water heating. Geothermal Cooling During the cooling mode, cold, refreshing air is circulated throughout the house by reversing the heating process. Heat is not pulled, instead it is driven 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.
