Is there just one way to install a closed loop system?
No, you can either do a horizontal ground closed loop or vertical ground closed loop. A horizontal ground closed loop is usually the most cost effective way to install, if there is enough yard space for trenches. It is best for a new home, but the option of horizontal boring is possible. Workers use trenchers or backhoes to dig the trenches six to eight feet below surface, and then lay a series of parallel plastic pipes down. The average length of a horizontal loop is 800 feet long per ton of heating and cooling capacity. The other option is a vertical ground closed loop system. This is ideal for homes with limited amount of yard space. A contractor bores vertical holes in the ground 150 to 450 feet deep. Each hole contains a single loop of pipe with a u bend at the bottom. After a pipe has been inserted, the hole is then backfilled or grouted. Each vertical pipe is then connected to a horizontal pipe, which is also concealed underground. The horizontal pope then carries fluid in a clo
