What is a trench system?

Most closed loop systems are laid horizontally in the ground adjacent to the building. But any area near a home or business with appropriate soil conditions and adequate space will suffice.

Ground loop pipe is normally laid to a depth of 1.2 metres (single trench) or 1.8 metres (double trench) in trenches of 1 metre wide and 1 metre apart.

The larger the area of ground and the greater amount of pipe installed yields higher and longer maintained temperatures, higher CoP (Coefficient of Performance) and better long term savings for the owner.
