How It Works - Closed-Loop Systems

Horizontal Loops

Horizontal Piping

If adequate land area without hard rock is available, a horizontal loop installation is usually the most economic. Horizontal loops are often used for newly constructed homes and commercial buildings.

A horizontal system uses a number of trenches. The piping can be configured in the trenches in several ways:

  • 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 to be buried. One of the advantages
of a horizontal loop system is being able to lay the trenches according to the size of the lot.
