Heat Pumps for Heating and Cooling Requires longer pipes because the ground temperatures are subject to seasonal temperature variations, rainfall, and snow melting. Obtaining the same system efficiency as the vertical loop requires a more complicated design with longer pipe lengths. The longer pipe lengths also require more antifreeze solution, when necessary. The pipe is at greater risk of damage during backfilling of the trenches. Because of relatively minor variations in deep soil temperature, heat pumps supplied from vertical earth loops will require less piping and provide relatively consistent heating and cooling capacity. Trenching costs are typically lower than the drilling costs associated with vertical loop installation. The costs will be lower particularly if undertaken during earthworks for the construction of a new building where earthmoving equipment is already on site. Drilling costs are frequently higher than the trenching costs associated with horizontal and spiral loops. A good access is required to get the drilling rig onto the site. They may not build up as much heat over time because the pipes are closer to the surface, where heat can be dissipated to the atmosphere. This may also make it a good application for melting ice in parking lots. Backfilling of the bore holes requires special attention to fill material and to ensure that the pipes and earth remain in contact. If the bore holes are spaced too close together, there is a potential for long-term heat buildup in the ground that may be undesirable. Unless data is available from geological survey in the immediate area, a geologist survey is recommended prior to project commencement. Unless data is available from geological survey in the immediate area, a test hole and/or a geologist survey is recommended prior to project commencement. 37PDF Image | Heat Pumps for Heating and Cooling
