Horizontal Loops
Horizontal
loops are installed if adequate land area without hard rock is available.
A horizontal loop installation is usually the most economic. They are often
used for newly constructed homes but can be installed in retrofit projects.
The horizontal system uses a number of trenches, a single pipe, multiple
pipes in a narrow trench, or multiple pipes in a wider trench. The trenches
are normally four feet deep or more, and vary in length depending on the
number of pipes buried.
