How Geothermal Works

We all know that Terre Haute homes are acceptable to varying temperatures throughout the year. Some climates can see the extremes 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 underneath 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 cumulated in the ground as heat. WaterFurnace geothermal systems draw from 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

Using the earth loop, a WaterFurnace geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and delivers this warmed air through a traditional duct system. Additional choices include using that same heat to provide hot water and radiant floor heating are available.

Geothermal Cooling

The heating process is reversed in the cooling mode - creating cold, conditioned air all through the home. Instead of pulling heat from the ground, heat is extracted 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.
