How Geothermal Works

As the seasons change from spring to winter, temperature fluctuates throughout the year. Some climates can vary from blazing summers to ice-cold winters; Augusta County included. Did you know there is a pretty 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 retained in the ground a few feet below the surface. WaterFurnace geothermal systems extract this free heat source with an earth loop. This inventive technology recovers 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 distributes it through a standard 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

The heating process is reversed in the cooling mode - creating cold, conditioned air all through the home. Instead of pulling heat from the ground, heat is taken from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
