And when some navvies slice through one of the pipes with their digger at some point in the future what's the repair cost?

Best not bother doing it then.

That's the sort of negativity that ... speck/plank?

Anyway, yes, you can run multiple lines - either as straight pipes or as slinkies.

They're having a laugh! Is that what installing a ground heat pump really involves?! No wonder it costs tens of thousands!

Boris the wonky shopping trolley is a Walter Mitty character, and away with the fairies!

To go a long way towards minimising the UK's carbon footprint, it would be far easier and more effective to ban air conditioning for cooling, and office fans that ran off the mains (as opposed to small desktop USB fans). There's no reason for supermarkets and shopping centres and offices to be like walk-in freezers.

No, those are photos to show the concept of how you can lay multiple pipes.

Eh? I'm engaged in a reasonable discourse on what's available and realistic. Disagreement isn't negativity.
