How Geothermal Works As the seasons change from spring to winter, temperature varies throughout the year. Some climates can range from sweltering summers to frigid winters; Medina included. Did you know there is a fairly constant 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 retained in the ground a few feet beneath the surface. WaterFurnace geothermal systems extract 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 Using the earth loop, a WaterFurnace geothermal heat pump extracts the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and distributes this warmed air through a standard duct system. Additional choices include using that same heat to provide hot water and radiant floor heating are available. 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 circulating throughout your home. Heating your water during this process is "free".
