How Geothermal Works We all know that Big Rapids 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 draw from this heating potential using an earth loop system; collecting this free heat for your home. This state-of-the-art 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 pulls the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and distributes this warmed air through a standard duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling In the cooling mode, the heating process is reversed - creating cool, conditioned air throughout the home. Instead of pulling heat from the ground, heat is taken 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.
