Repiping and Reconfiguring our Heat Pump System Including Removing the Buffer Tank - Heat Pump Retrofix
@jamespa talking of being old, the house where I grew up had a multi zone heating system. Downstairs had radiators, upstairs didn't 😂
I remember scratching my name onto the frost on the inside of my bedroom window. Curiously I don't ever remember feeling cold though 😁
Now we (rightly) get upset if the room doesn't get upto temperature, how times have changed.

And we (or at least some) expect to be able to do 5-4 showers in quick succession every day, and many other (largely luxury) thinks we now take for granted.
And yet people still aren't satisfied and moan about their lot. Really?

Yup
Sadly consumerism, the foundation of our economy, depends on making us unhappy and thus buying ever more stuff to keep up with the neighbours or temporarily deal with our unhappiness.
This is of course totally unsustainable, but the lemmings have been 'educated' by the largely shallow self-interested media not to see that and as a result many vote for whichever self-interested individual tells them the lies they want to hear thus sealing their own, and more particularly their childrens' fate.
It's somewhat depressing.

@jamespa The dormitories at my boarding school (in Exeter) had ice formed on the inside of the windows (single glazed of course) and that ice would sometimes be resident for several days at a time. Meanwhile, at home in Somerset, we had to keep a coal fire burning throughout the summer if we required any hot water as a back of fireplace heat exchanger mechanism was all we had. My Dad eventually installed an immersion heater in the DHW tank in about 1958/9 to alleviate the situation in our ‘shoebox’.😉 Toodles.

Day one is done.
The system’s been fully flushed and cleaned, and every lockshield has been swapped out for FRVs. They look fantastic and they’ve already exposed major flaws in our system (two in fact!).
This is shaping up to be an epic project and a huge learning experience. We’ve also filmed the first part of our video and we’re off to a flying start.

@editor your engineer's attitude is truly horrifying. I suspect he realises that he messed up, but can't bear to face up to it.
Anyway, once The Maestro has sorted it out, you will have dramatically improved performance and demonstrably reduced heating bills. Then, your position will be incontrovertible.
Of course, what you do with that information will be up to you.

Day 2 was a beast. All the excess zoning, on/off stats and buffer related piping, plumbing and wiring is gone. Day 3 is about putting everything back to together as an open zone and balancing all our emitters. I'll make sure @heacol gets regular coffee throughout the day to help him power through.

There's a couple of motorised valves I can see there.
Put them on ebay, and you'll be able to cover the cost of Brendon's coffee for the duration.
How much insulation wall thickness is left, I wonder, after compressing it with nylon cable-ties?

If it weren't for that original installer, none of us would be here on this forum.
Save energy... recycle electrons!
@editor this is exciting! It will be great to hear how things go.
