ECONAR^® Energy Systems - Earth Loop Field
Wesley Homes Vertical Loop

Physical Data

Wesley Homes, a premier home builder in the greater Metropolitan area of Minneapolis and St. Paul, has incorporated ECONAR GeoSource Heat Pumps into many of his new homes. This home, in an upper end development and with yard area at a premium, utilizes a vertical earth loop. The vertical loop system consists of 10 holes and bored to a depth of 96 feet each and spaced 10 feet apart. A high density PE3408 plastic pipe is inserted into every hole, connected at the bottom with a u-bend. All underground connections are fusion welded by the certified loop installer. The holes are then sealed using a bentonite grout and piped together to a common manifold that runs into the building below the frost line. The fluid that flows through the vertical loop system is a combination of water and food grade antifreeze. The system has an expected design life of 200 years and carries a 50-year warranty on the pipe from the manufacturer.
