How Does Geothermal Work?
HVAC systems using geothermal energy utilize ground loops comprised of special, heavy duty pipes made from polyethylene. These pipes contain water and/or a Geo solution which are buried in the ground. Once in the ground where depth varies based on each site, the liquid circulation begins. Water moves through the pipes, extracting heat and energy from beneath the surface of the earth, and then moves into the geothermal system in your home or business. At this point, the pipes either extract heat from the house to cool it, or dump heat into the ground under the house to warm it.
An HVAC system utilizing geothermal energy is different from a typical system which utilizes an indoor unit with a fan, cooling coil and an outdoor compressor. Geothermal HVAC units are best described as a two-part system:
- Indoor unit—contains coil, fan, compressor and exchanges
- Outside pump and ground loop—circulates the geo-solution to warm or cool the exchanger.
Reports show that there are currently around one million geothermal energy units in homes and businesses throughout the United States. While the idea of using water along with the earth’s underground temperature to maintain comfortable indoor climate has been around for more than 100 years, it is just now becoming more popular and easier to access.
For homeowners and business owners who are seeking a cost-effective way to heat and cool their homes and businesses while being kind to the environment, geothermal energy offers a practical solution. It may seem foreign to people who are unfamiliar with alternative energy sources, but working with Waldrop Inc. will give you the knowledge and confidence you need to begin using geothermal energy.
