ECR's DIRECT AXXESS^® Earth Loops

Horizontal Loop

The horizontal loop application is an excellent choice for areas of the country where overburden depths of at least 4-6' exist. Excavation costs must be compared to the cost of drilling either the vertical option or the diagonal option illustrated above. There are also restrictions that apply to the horizontal loop field such as the inability to plant deep-rooting trees, erect buildings such as garages or out buildings, and obviously swimming pools (either in-ground or above-ground) would be prohibited. Despite these restrictions however, a number of homeowners opt for this type of loop field and successfully implement this design on a regular basis.

Vertical Loop

The vertical loop application is also an excellent choice, and available in all areas of the country. For this type of loop application, the services of a drilling contractor would be required to drill the 3" bore hole required for the loop itself. As you can see from the illustration, the horizontal loop option requires less space and therefore minimizes restrictions in use above the loop field.

Diagonal Loop

The diagonal loop is probably the very best choice in loop application. With its small "footprint" there are minimal restrictions in use above the loop field; this allows the homeowner complete freedom to utilize their lot or yard in any way they choose. The manifold area is the only area that must be protected from buildings, trees or pools above. As with the vertical loop option, the diagonal also requires the services of a drilling contractor to drill the 3" bore holes required.
