How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climatic zones that means hot summers that cool to frigid winters, and Central New Jersey is no exception. What most people don't understand is that the temperature below ground (regardless of climate or season) stays fairly consistent all year. The ground is able to retain a higher rate of constant temperature because it takes in 47% of the sun's energy (heat) as it hits the Earth's surface. WaterFurnace geothermal systems are able to draw from this free energy with an earth loop. This technology is then used to equip your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump utilizes the earth loop system to draw the heat from the ground. With delivery through a classic duct system, the geothermal system pulls heat from the loops and distributes it as warm air. Options are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling In the cooling mode, the heating process is reversed - creating cold, conditioned air throughout the home. Instead of pulling heat from the ground, heat is taken from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
