No matter what climate you live in, the temperature throughout the year varies. For some climates, that means blazing summers that cool to frigid winters. What many people don’t realize is that the temperature below ground (regardless of climate or season) stays fairly consistent all year.
The ground is able to maintain a higher rate of temperature consistency because it absorbs 47% of the sun’s energy (heat) as it hits the Earth’s surface. Water Furnace geothermal systems are able to tap into this free energy with an ‘earth loop’. This technology is then used to provide your home or office with central heating and cooling.
During the heating cycle, a Water Furnace geothermal system uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or domestic hot water heating.
In the cooling mode, a Water Furnace geothermal system air conditions your home by reversing the heating process. Instead of extracting heat from the ground, it is extracted from your home and either moved back into the earth loop, or used to preheat the water in your hot water tank. Once the heat is removed from the air, it is distributed through the duct system in your home.
