How Geothermal Works

As the seasons change from spring to winter, temperature fluctuates throughout the year. Some climates can range from fiery summers to frigid winters; Grand Forks Area included. Did you know there is a fairly consistent temperature, regardless of climate or season, just below the ground?

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

Geothermal Heating

During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system draws heat from the loop it circulates it through a traditional duct system as warm air. The same heat energy can also be put to use for a radiant floor system or domestic hot water heating.

Geothermal Cooling

During the cooling mode, cool, conditioned air is circulated throughout the house by reversing the heating process. Heat is not pulled, 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 technique as well.
