Here Are the Facts on Residential Loops
Three Basic Geothermal Energy Sources
Closed-loop systems circulate a water-based solution through a "loop system " of small-diameter, high-density polythylene underground pipes. Closed-loop systems can be installed horizontally, vertically or in a pond. Open-loop systems use an existing water well or surface water. Regardless of whether the system is open or closed, heat is transferred to or from the structure to provide year-round comfort, no matter what the outdoor temperature is.
