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 ice-cold winters, and New Jersey is no exception. What many 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 sustain a higher rate of temperature consistency because it absorbs 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 utilized to equip your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump employs the earth loop system to extract the heat from the ground. With delivery through a standard duct system, the geothermal system pulls heat from the loops and circulates 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 cool, conditioned air throughout the home. Instead of extracting 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.
