How Geothermal Works We all know that Western Montana homes are subjected to varying temperatures throughout the year. Some climates can see the extremes that summer and winter hit us with. There is a dependable source of temperature that you can put to good use; just a few feet under the earth's surface. How is that possible? The sun instills the Earth's crust with its heat energy. Forty-seven percent of that energy is cumulated in the ground as heat. Our geothermal systems extract this heating potential using an earth loop system; collecting this free heat for your home. This state-of-the-art technology uses the sun's heat that the earth has conveniently deposited to condition your home or office. Geothermal Heating Using the earth loop, a geothermal heat pump takes 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.
