How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climates that means hot summers that cool to frigid winters, and Manhattan is no exception. What many people don't understand is that the temperature underground (regardless of climate or season) stays fairly consistent all year. The ground is able to maintain a higher rate of constant temperature because it absorbs 47% of the sun's energy (heat) as it hits the Earth's surface. Our geothermal systems are able to draw from this free energy with an earth loop. This technology is then utilized to equip your home or office with central heating and cooling. Geothermal Heating Utilizing the earth loop, a geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and passes this warmed air through a conventional duct system. Additional choices include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling During the cooling mode, cold, refreshing air is circulated throughout the house by doing the exact opposite as the heating process. Heat is not pulled, instead it is driven into the ground. The warm heat is extracted from your home and taken back into the earth loop. Your hot water heating can be fueled by this procedure as well.
