How Geothermal Works As the seasons change from spring to winter, temperature varies throughout the year. Some climates can vary from blazing summers to chilly winters; West Chester included. Did you know there is a pretty 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 maintained in the ground a few feet below the surface. WaterFurnace geothermal systems draw from this free heat source with an earth loop. This ingenious technology salvages the sun's heat supplying your home or office with central heating and cooling. Geothermal Heating Using the earth loop, a WaterFurnace geothermal heat pump extracts the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and passes this warmed air through a traditional duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. 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 getting rid of the warm air, all that is left is cool air dispersing 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 West Chester area, contact Sinton Air Conditioning & Heating, Inc..
