How Geothermal Works The temperature throughout the year will always vary no matter what climate you live in. For some climatic zones that means hot summers that cool to frigid winters, and New Jersey is no exception. What many people don't realize is that the temperature underground (regardless of climate or season) stays pretty consistent year round. 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 provide 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 standard duct system, the geothermal system draws heat from the loops and circulates it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat. 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 removing the warm air, all that is left is cool air radiating throughout your home. There is no cost to heating your water during this process. For more information on how to get started with a geothermal system in the New Jersey area, contact J. Zanes LLC.
