How Geothermal Works

We all know that Southwest Michigan homes are subjected 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 put to good use; just a few feet below 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 draw from 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 conveniently accumulated 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 circulates it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or household hot water heating.

Geothermal Cooling

During the cooling mode, cool, 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 transferred back into the earth loop. Your hot water heating can be fueled by this procedure as well.
