Open Loop (Well Water)
In ideal conditions (a little rare), an open-loop can be the lowest cost type of GHP installation for your home. Open loops use groundwater from a well as a direct energy source.
When you own enough land around your home, horizontal loops can be the ideal earth loop system to install. Depending on the exact system needs and space available around your home, pipes are placed in trenches that range in length from 100 to 400 feet.
When not much yard or land is available, a vertical earth loop can be the way to go for your GHP installation. Small diameter holes are bored into the ground using well drilling equipment. The polyethylene piping is then installed into these holes that range from 100-400 feet deep!
