How Geothermal Works

We all know that Knoxville homes are acceptable to varying temperatures throughout the year. Some climates can see the extremes that summer and winter hit us with. There is a consistent source of temperature that you can put to good use; just a few feet under the earth's surface. How is that possible?

The sun instills 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; harvesting this free heat for your home. This innovative technology uses the sun's heat that the earth has readily deposited to condition your home or office.

Geothermal Heating

In the heating cycle, a WaterFurnace geothermal heat pump utilizes the earth loop system to draw the heat from the ground. With delivery through a traditional duct system, the geothermal system pulls 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

During the cooling mode, cold, refreshing air is distributed through the house by doing the exact opposite as the heating process. Heat is not pulled, instead it is driven into the ground. The warm heat is pulled from your home and transferred back into the earth loop. Your hot water heating can be fueled by this process as well.
