How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to freezing winters, and Dallas is no exception. What many people don't understand is that the temperature underground (regardless of climate or season) stays fairly consistent all year. The ground is able to sustain a higher rate of constant temperature because it absorbs 47% of the sun's energy (heat) as it impacts the Earth's surface. Our geothermal systems are able to draw from this free energy with an earth loop. This technology is then utilized to provide your home or office with central heating and cooling. Geothermal Heating During the heating cycle, a geothermal heat pump uses the earth loop to draw heat from the ground. As the system pulls heat from the loop it distributes it through a traditional duct system as warm air. The same heat energy can also be utilized for a radiant floor system or household hot water heating. 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.
