How Geothermal Heating and Cooling Works
Geothermal renewable energy draws upon the Earth’s consistent temperature. Yes, the average Indiana air temperature ranges from 89˚ to 16˚ throughout the year with peaks and valleys that can result in 100+˚ days in the heat of summer and sub-zero days in the dead of winter. However, you may not realize that about four to six feet below the Earth’s surface, the temperature remains relatively moderate and consistent all year, about 50˚– 60˚.
Because the ground absorbs 47% of the sun’s energy (heat) as it hits the Earth’s surface. Geothermal systems are able to tap into this free, renewable energy with an earth loop and provide heat and cool for your home.
