How Geothermal Works

Average Florida temperatures range from 89 to 16 throughout the year. Of course, we have 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. Why? 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.

How it heats

During the heating cycle, a geothermal system uses the earth loop to extract heat from the ground. As the system pulls heat from the loop, it distributes it through a conventional duct system or radiant floor system as warm air. Plus, as a bonus, it provides water heating for household use.


How it cools

In the cooling mode, a geothermal system cools your home by reversing the heating process. Instead of taking heat from the ground, it is removed from your home and either moved back into the earth loop or used to preheat your household water. The cool air is then distributed through the duct system in your home.
