How Geothermal Works The temperature throughout the year will always vary no matter what climate you live in. For some climates that means blazing summers that cool to frigid winters, and Pine County is no exception. What many people don't understand is that the temperature below ground (regardless of climate or season) stays pretty consistent year round. The ground is able to sustain a higher rate of constant temperature because it absorbs 47% of the sun's energy (heat) as it hits the Earth's surface. Our geothermal systems are able to draw from this free energy with an earth loop. This technology is then put to use to equip your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a geothermal heat pump utilizes the earth loop system to draw the heat from the ground. With delivery through a standard duct system, the geothermal system draws heat from the loops and distributes it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat. 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 extracted 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.
