How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can vary from blazing summers to ice-cold winters; Lafayette included. Did you know there is a pretty consistent temperature, regardless of climate or season, just below the ground? The Earth's crust takes in 47% of the sun's heat (energy) and is maintained in the ground a few feet underneath the surface. WaterFurnace geothermal systems draw from this free resource with an earth loop. This innovative technology reclaims the sun's heat providing 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 extract heat from the ground. As the system draws heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be put to use for a radiant floor system or domestic hot water heating. Geothermal Cooling Cooling the air is just the reverse process used in the heating cycle. Warm air is driven by the geothermal heat pump into the ground. By removing the warm air, all that is left is cool air radiating throughout your home. Heating your water during this process is "free". For more information on how to get started with a geothermal system in the Lafayette area, contact Korschot's Heating and Air.
