How Geothermal Works We all know that Reading 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 consistent source of temperature that you can put to good use; just a few feet beneath 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; 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 employs the earth loop system to extract the heat from the ground. With delivery through a standard duct system, the geothermal system draws heat from the loops and circulates it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling The heating process is reversed in the cooling mode - creating cool, 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.
