Geothermal HVAC - How It Works
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. In our region, it varies between 52 and 55 degrees.
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. 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 geothermal heat pump 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, the heating process is reversed - creating cool, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted 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.
Geothermal vs. Geoexchange: What's in a name?
Geothermal energy has been used to heat and air condition buildings for several decades, and during that time these geothermal systems have been called many different things. Some of the more popular variations include geothermal, geoexchange, ground-water, ground-water assisted, ground-water-source, water-to-water, and even our company name, Geo Systems heating and cooling.
