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 Des Moines is no exception. What most people don't understand is that the temperature below ground (regardless of climate or season) stays fairly consistent all year. The ground is able to sustain a higher rate of temperature consistency because it takes in 47% of the sun's energy (heat) as it hits the Earth's surface. WaterFurnace geothermal systems are able to extract 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 During the heating cycle, a WaterFurnace 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 Conditioning air is just the reverse process used in the heating cycle. Warm air is pushed by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air circulating throughout your home. There is no cost to heating your water during this process. For more information on how to get started with a geothermal system in the Des Moines area, contact Sherman Co. LLC.
