How Geothermal Works

We all know that Pittsburgh homes are acceptable to varying temperatures during the year. Some climates can see the extremities that summer and winter throw at us. There is a dependable source of temperature that you can utilize; just a few feet below the earth's surface. How is that possible?

The sun infuses 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; harvesting this free heat for your home. This state-of-the-art technology uses the sun's heat that the earth has readily accumulated to condition your home or office.

Geothermal Heating

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

Geothermal Cooling

In the cooling mode, the heating process is reversed - creating cold, conditioned air all through 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.
