How Geothermal Works As the seasons move from spring to winter, temperature fluctuates throughout the year. Some climates can range from fiery summers to freezing winters; Denver included. Did you know there is a fairly consistent temperature, regardless of climate or season, just below the ground? The Earth's crust absorbs 47% of the sun's heat (energy) and is sustained in the ground a few feet underneath the surface. WaterFurnace geothermal systems draw from this free heat with an earth loop. This creative technology recovers the sun's heat supplying your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump employs the earth loop system to draw the heat from the ground. With delivery through a traditional duct system, the geothermal system pulls heat from the loops and circulates it as warm air. Options are available to use that same heat energy to provide hot water heating and radiant floor heat. 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 removing the warm air, all that is left is cool air radiating 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 Denver area, contact Sensible Heating & Cooling.
