For a heat pump (geothermal) to operate, it is necessary to install a heat collection system in the ground.
There are two main ways to gain access to ground heat:
- Horizontal system
- Vertical system
Horizontal heat collection system
A horizontal heat collection system involves digging a trench 1 or 2 metres deep, then burying pipes. A wide trench needs to be dug, and coiled plastic pipe, coiled into ‘slinkies’ is buried. On average 10 metres of trench is needed for each kilowatt of power. This is likely to mean digging at least 100 metres of trench work – a considerable earthworks exercise. This can be an off-putting, expensive and disruptive collection solution.
Vertical heat collection system
WB+AD Morgan uses a vertical ground source heat collection system. This simply involves drilling one or more boreholes straight down into the earth. The vertical system eliminates the need to dig extensive trenches and reduces the level of disturbance, delivering overall consistency and efficiency.
Utilising a borehole is the most efficient way of extracting heat from the ground. A boiler-sized heat pump is carefully installed by a Morgan in-house NICEIC electrician.
Why boreholes are the best source of ground heat…
Borehole vertical ground source heat systems bring major advantages:
Far less disruption: they eliminate the need to dig and re-cover massive trenches. Trenching is a major exercise, and in many instances – for most domestic properties, and many commercial premises – the space is simply not available.
Better consistency and efficiency: unlike trench systems, the underground temperature is consistent and heat is extracted more efficiently.
