How Geothermal Works We all know that Southeast Missouri 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 underneath the earth's surface. How is that possible? The sun infuses the Earth's crust with its heat energy. Forty-seven percent of that energy is stored in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; collecting this free heat for your home. This innovative technology uses the sun's heat that the earth has conveniently accumulated to condition your home or office. 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 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 In the cooling mode, the heating process is reversed - creating cold, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
