Heat Pumps for Heating and Cooling removed. The remaining pipe should be completely filled with high solids bentonite slurry. The slurry should be allowed to spill into the excavation to provide a cap at least 0.3m thick above the pipe. The remainder of the excavation should be filled with compacted earth or pavement. Summarizing.... • Ground source heat pumps are not highly dependent on weather conditions and can be used effectively in most locations. However, the composition and properties of soil and rock impact heat transfer rates. • Horizontal ground loops (generally the most economical) are typically used for newly constructed buildings with sufficient land. Horizontal slinky installations are often used for existing buildings, because they minimize the disturbance to the landscape, existing underground utilities and sprinkler systems. • Vertical ground loop installations may be used (instead of horizontal ground loops) in areas with extensive hard rock or with soils that are too shallow to trench. However, these systems cost higher than the horizontal ground loops. • Ground source heat pumps can be more efficient compared to air-source heat pumps (ASHP) during winter, because the temperature in the ground is higher than the ambient air temperature. COP stays stable throughout the year because the temperature does not differ much. Defrost and auxiliary heating is not required. As a GSHP has fewer moving parts, it may also enjoy a longer working life. • The main disadvantages of ground-source heat pump systems are high capital costs and big space requirement for the pipe system. On average, a ground source heat pump costs about $2,500 to $3,500 per ton of capacity, or roughly $7,500 to 10,000 for a 3-ton unit (typical residential size). In comparison, other systems would cost about $4,000 with air conditioning. ********* 47PDF Image | Heat Pumps for Heating and Cooling
