Heat Pumps for Heating and Cooling borehole diameter should be minimized (to approximately 5” diameter) to limit the grout’s effect. Some state and local governments have specific requirements for grouting boreholes to protect the integrity of ground water. Be sure to verify and comply with any such local requirements. The two most common borehole heat exchanger designs are U-pipes and coaxial (concentric) pipes. 3.4. Horizontal Loop Systems A horizontal loop runs piping parallel and close to the surface. The pipes are laid in shallow trenches and a working fluid is circulated through the network of pipes and provides the medium for heat transfer from the ground. Horizontal loops are easier to install but require significantly more area (approximately 2500 ft2/ton). The pipes are located typically 6 ft. (1.8 m) deep and spaced 6 to 15 ft. (1.8 to 4.6 m) apart. The pipe material is usually high density polyethylene (HDPE) and is usually 3⁄4 - 11⁄2” (~20 – 40mm) diameter. As a thumb rule, horizontal loops can range from 100 to 400 ft. of trench length per ton of cooling. Heat extraction rates are generally influenced by soil properties and other factors. 34PDF Image | Heat Pumps for Heating and Cooling
