An anecdote to go with the previous post. A friend of mine has a neighbour who lives in a house heated by a ground-sourced heat pump via a borehole. Or it was heated by a ground-sourced heat pump, but the underground tubing began to leak.
The problem was far too expensive to fix when compared to installing a gas boiler, so that's what my friend's neighbour did - he abandoned the heat pump and installed a gas boiler.
"Hello, is that Homebase? I wonder if you can help me. I'm looking for a tool that can locate and extract a pipe full of antifreeze that's in a narrow grouted tube three hundred feet under my newly relaid lawn. Do have anything like that? No? OK, no worries, I've got all Sunday morning and I haven't tried B&Q yet..."
ReplyDeleteSam - the assumption seems to be that it could never happen. Like an unusually protracted windless period when Net Zero means we need reliable wind power.
