How Geothermal Works

We all know that Tennessee Valley homes are acceptable to varying temperatures during the year. Some climates can see the extremities 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 below 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 cumulated in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; gathering this free heat for your home. This state-of-the-art 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 utilizes the earth loop system to extract the heat from the ground. With delivery through a traditional duct system, the geothermal system pulls heat from the loops and distributes 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 cold, 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.
