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 Richmond is no exception. What many people don't realize is that the temperature underground (regardless of climate or season) stays fairly consistent all year. The ground is able to sustain a higher rate of temperature consistency because it takes in 47% of the sun's energy (heat) as it impacts the Earth's surface. WaterFurnace geothermal systems are able to tap into this free energy with an earth loop. This technology is then put to use to provide your home or office with central heating and cooling. Geothermal Heating During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system draws heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be put to use for a radiant floor system or domestic hot water heating. Geothermal Cooling During the cooling mode, cold, conditioned air is circulated throughout the house by reversing the heating process. Heat is not pulled, instead it is pushed into the ground. The warm heat is pulled from your home and moved back into the earth loop. Your hot water heating can be fueled by this process as well.
