The Ground Loop Field

A horizontal ground loop field is a solution for homes or buildings that sit on at least 1/2 acre. By using chain trenchers, backhoes, and/or trackhoes, loop installers dig 4 – 8 feet below ground, with trench lengths stretching 100 – 300 feet per ton.

A vertical ground loop field is an option when less land area is available. Boreholes are drilled by a drilling rig at a depth of 150 – 300 feet per ton, with high-density pipes placed in the boreholes and backfilled with a sealant.

The pond loop system utilizes a nearby body of water at least 1/2 acre big and 10-to 12-feet deep. Pipes 300 – 500 feet long are coiled and anchored just above the bottom.

Open loop systems work with a supply of high-quality well water. A typical home requires 9 – 15 gallons of water per minute. A river, drainage ditch, or pond close by is needed for discharge.
