How Geothermal Works

We all know that homes are subjected to varying temperatures throughout the year. Some climates can see the extremes 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 imparts 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 stored to condition your home or office.

Geothermal Heating

Utilizing the earth loop, a WaterFurnace geothermal heat pump extracts the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and passes this warmed air through a classic duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available.

Geothermal Cooling

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