Geothermal Earth Loops
Closed-loop systems circulate a water-based solution through a “loop system” of small-diameter underground pipes made of high-density polythylene. They can be installed horizontally, vertically or in a pond.
- Williams Vertizontal™ Loop… an ideal choice for a geothermal heat pump when you don’t want your yard torn-up or there is limited land surface. It is a new, innovative ground loop available ONLY at Williams Comfort Air. It goes down 20 to 25 feet getting into the water table providing great heat exchange. Tell me more!
- Horizontal Loop… often used when adequate land surface is available. Depending on geothermal system needs and space available, pipes are placed in trenches that range in length from 100 to 400 feet.
- Vertical Loop… an ideal choice for a geothermal heat pump when there is limited land surface. Well-drilling equipment is used to bore small-diameter holes from 100 to 400 feet deep.
- Pond (Lake) Loop… very economical to install when a large body of water is available for use by the geothermal heating and cooling system. Coils of pipe are simply placed on the bottom of the pond or lake to capture the geothermal energy.
Open Loops can be the most economical type of geothermal system, in ideal conditions. These use groundwater from a well as a direct energy source. Whether the system is open or closed, heat is transferred to or from the structure, regardless of outdoor temperature, to provide year-round comfort.
