How Geothermal Works

How Geothermal Works

As the seasons change from spring to winter, temperatures fluctuate throughout the year. Some climates can range from blazing summers to chilly winters; Ellsworth included. Did you know there is a pretty consistent temperature, regardless of climate or season, just below the ground?

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

Geothermal Heating

Using 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 traditional duct system.

Additional available options include using that same heat to provide hot water and radiant floor heating.

Geothermal Cooling

During the cooling mode, cool, conditioned air is distributed throughout the house by doing the exact opposite as the heating process. Heat is not extracted, instead it is pushed into the ground. The warm heat is pulled from your home and transferred back into the earth loop. Your hot water heating can be fueled by this process as well.
