How Geothermal Works

As the seasons move from spring to winter, temperature varies throughout the year. Some climates can vary from blazing summers to frigid winters; Western Montana 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 draw from this free heat source with an earth loop. This inventive technology reclaims the sun's heat providing your home or office with central heating and cooling.

Geothermal Heating

Utilizing the earth loop, a WaterFurnace geothermal heat pump extracts the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and passes this warmed air through a standard duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available.

Geothermal Cooling

In the cooling mode, the heating process is reversed - creating cold, conditioned air all through the home. Instead of extracting 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.
