Air ConditioningWhat Is a Geothermal Loop?

Geothermal heating and cooling has really caught on this part of the country, as homeowners look for more efficient and environmentally ways in which to maintain comfort, without compromising it, throughout their homes. One of the vital components of any geothermal system is the geothermal loop. While geothermal heating and cooling is rather simple in concept, many homeowners are not quite clear in regards to the role that this unfamiliar system plays in the geothermal experience. Here is some information from the Everett, WA geothermal pros on our staff to help you better understand what it is that the geothermal loop accomplishes, and how it does so. Contact G & S Heating Cooling & Electric to schedule your geothermal services with trained, experienced technicians. 

The geothermal loop is a system of tubing that is most often installed in the ground on one’s property, at a depth which retains a relatively constant temperature throughout the year. In some setups, the loop may be placed in a body of water, alternatively. Typically, the geothermal loop is installed in a horizontal fashion, requiring sufficient space in order to function properly. However, there are exceptions to this as well. The vertical installation is an option that some homeowners pursue if there is not enough space on their property to accommodate the horizontal installation of this tubing. A vertical installation requires deeper depths to be excavated.

Throughout the loop system courses an antifreeze solution, most commonly, which acts as the heat transfer liquid. Some systems, depending upon environmental considerations and the method of installation, may simply use water in its stead. Regardless, this liquid will absorb heat from its surrounding environment during the winter season, and this heat is transferred to refrigerant in the heat pump. In the summer time, when cooling your home, the loop system and the liquid it contains transfers the heat back into the ground. To learn more about geothermal heating and cooling, its benefits, and what the installation of such a system may entail, just give a member of our staff a call.
