How Geothermal Works

As the seasons move from spring to winter, temperature varies throughout the year. Some climates can range from blazing summers to cold winters; Lancaster 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 retained in the ground a few feet below the surface. WaterFurnace geothermal systems tap into this free heat source with an earth loop. This creative 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 traditional duct system as warm air. The same heat energy can also be used 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 removing the warm air, all that is left is cool air dispersing throughout your home. Heating your water during this process is "free".
