\"Solutions<\/a><\/p>\n

Ground source heat pumps can extract energy from the ground or water using a closed loop or open loop\u00a0collector.\u00a0The size of the array is dependent on a number of factors including but not limited to the peak heating and cooling loads and usage of the building.<\/p>\n

The most common design is to use a horizontal collector buried in a trench 1.2m deep x 1m wide. This method does require a large amount of ground and can not be used to build on. A typical 3 bedroom house would require 300-400m of pipe.<\/p>\n

If space is an issue then a vertical borehole can be drilled. The bore hole is drilled to depths of up to 150m for residential properties. One of the most important factors with drilling is to ensure a thermal grout is pumped in to remove air from around the bore hole pipe. A lot of companies do not do grout\u00a0and rely on the water table which will vary throughout the year. This will cause inefficiencies in the heat pump and potential system failure.<\/p>\n

\"Ground<\/a><\/p>\n

The slip trench design uses a 200mm wide bucket to install a single collector pipe. Trenches must be a minimum of 1m apart.<\/p>\n

\u00a0<\/strong>The open trench design uses a 1m wide bucket to install the collector pipe either side of the trench. Trenches must be a minimum of 1m apart.<\/p>\n","protected":false},"excerpt":{"rendered":"
