Thank you. Can I strongly advise those planning to install a GSHP to use recommended drillers. Without going into too much detail the use of a cut-price drilling company is now costing around £50,000 in repairs. They hit a water source and didn't deal with it properly resulting in serious subsidence. The occupier wasn't informed and only became aware when the house was affected four years later. A competent drilling company would have avoided this.
Great Video and I have a few Questions: The biggest advantage of HDPE besides its long life expectancy, are its heat-fused joints which make the pipe a single homogenous pipeline. Joints in traditional piping materials are the biggest source of leakage. Do you think comprssion fittings are ok for places where the earth may settle or move a little bit? Are you using insullation over the pipes in the header area that are 6' underground or is it just above ground?
Thank you for your informative videos. I'm concerned about the amount of groundwater and drilling sludge brought to the surface. Approximately how much is typically produced from an 80 metre borehole and how is this managed by the drillers?
Never mind fracking - I think I'd be far more worried about the combined effect of too many people drilling up to 800 metres (80m for a small house, 800 for a larger house) in their gardens! If this is the way our government wants to take us towards a carbon free existence I won't be participating.
What are you on about? this is a static closed system install once its installed its part of the land and the chemicals inside the system are closed and stopped from interacting with the environment. Fracking on the other hand is an open system of injecting at very high-pressure water into the land and then getting gas to precipitate out of the hole... If you can’t see the difference between the too then you are lost....
@@GammaSouljah To the contrary, I fully understand the difference between the 2 systems. It's the multiple bore holes that are my concern, particularly in areas with unstable subsurface layers. I dug a hole for a tree in my garden once and the neighbour's shed slipped on its foundation! Repeated boring to these depths in close proximity to buildings (some with dodgy foundations) is a recipe for trouble.
@@MrWillow6 The upper part of the borehole is sleeved and the space in the hole around the pipe is filled with grout so there's no voids. The borehole is only 6" wide in the largest systems.
