How Geothermal Works

As the seasons move from spring to winter, temperature fluctuates throughout the year. Some climates can range from blazing summers to frigid winters; Traverse City included. Did you know there is a fairly constant temperature, regardless of climate or season, just below the ground?

The Earth's crust takes in 47% of the sun's heat (energy) and is retained in the ground a few feet underneath the surface. WaterFurnace geothermal systems extract this free heat with an earth loop. This innovative technology reclaims the sun's heat supplying 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 draw 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 utilized for a radiant floor system or domestic hot water heating.

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 radiating throughout your home. There is no cost to heating your water during this process.
