GSHP much more efficient tha ASHP for obvious reasons.

Can i ask the person who posted that his local council were replacing GSHP with AHSP why that was the case?

I would suspect it is tied in with maintenance costs ??

Mine is because the service cost of a ground one is higher and once it breaks it is apparently expensive to replace. They are older ones too so I guess they want to do it now. I was told the ground one at the time was only expected to last 10 years before the whole system needed to be replaced. Seems weird to replace a perfectly working system but whoever is making the decision isn't paying for it themselves!

If you've got 100 properties under management, all with the same GSHPs that are approaching the end of their lives it's probably cheaper to contract with one big company to do all 100 at once than it is to make 100 ad-hoc contracts as they fail in turn. Also it keeps your tenants happy as they don't have to put up with a broken heat pump while you find someone to replace it!

Whilst i have never owned a GSHP (i'd love one) i find it hard to believe that the ground loop would require ANY maintenance after 10 years. Surely its just a piece of blue plastic 'water' pipe as used by every water company in the UK? I'd expect it to last 50 years or more!

Is not the rest of the equiptment above ground, and easily servicable? All seems a bit strange to me!

Some GSHPs use deep boreholes, rather than a buried "slinky" under the lawn.  That's the only way to do it if there isn't enough garden to dig up.

True. Perhaps while they are boring, they might find some gas down there. Brucie bonus!
