How Geothermal Works

We all know that Bloomington 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 consistent source of temperature that you can utilize; just a few feet underneath the earth's surface. How is that possible?

The sun permeates the Earth's crust with its heat energy. Forty-seven percent of that energy is stored in the ground as heat. WaterFurnace geothermal systems tap 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

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 pulls heat from the loops and circulates it as warm air. Options are available to use that same heat energy to provide hot water heating and radiant floor heat.

Geothermal Cooling

During the cooling mode, cold, conditioned air is circulated throughout the house by doing the exact opposite as the heating process. Heat is not pulled, instead it is pushed into the ground. The warm heat is extracted from your home and moved back into the earth loop. Your hot water heating can be fueled by this process as well.
