How Geothermal Works

As the seasons change from spring to winter, temperature fluctuates throughout the year. Some climates can vary from scorching summers to chilly winters; Columbus, Ohio included. Did you know there is a fairly constant temperature, regardless of climate or season, just below the ground?

The Earth's crust absorbs 47% of the sun's heat (energy) and is sustained in the ground a few feet below the surface. WaterFurnace geothermal systems extract this free heat source with an earth loop. This innovative technology reclaims the sun's heat supplying your home or office with central heating and cooling.

Geothermal Heating

In the heating cycle, a WaterFurnace geothermal heat pump employs the earth loop system to extract the heat from the ground. With delivery through a traditional duct system, the geothermal system pulls heat from the loops and distributes it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat.

Geothermal Cooling

Cooling the air is just the reverse process used in the heating cycle. Warm air is driven by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air dispersing throughout your home. Heating your water during this process is "free".
