I only used pur under my concrete floor (no way to catch fire) but used rockwall everywhere else (rockwall not capable of supporting concrete ?‍♂️).

All I can say is I am glad my build is finished, missed planners not talking, missed shortage of materials and high prices, I am very lucky, I don’t envy anyone trying to deal with any of the above.

No, my cavity was 200mm, no picture (must be the only thing I didn’t take a photo of) but similar to picture above by @tonyshouse.

Wet plaster, block, wide cavity with beads or batts, brick, (I don’t like render, needs maintenance).

That was my guess but not sure, common @ToughButterCup give us a straight question we can understand (I don’t speak upnorth)

Yes tell us the problem/fault, I have one (self installed).

I guess you will hear any fan heater heater?

Will report back with a review when it arrives next week ?

Oh I do love an optimist (they been saying this for years).

Actually that looks good, I too may need a little extra heat in bedrooms in very cold weather so might get one myself. ha, out of stock but just ordered one of these on EBay, worth a punt. https://www.ebay.co.uk/itm/124984666311?_trkparm

That’s because it was designed to go on the garage roof i only use timber felled on site because it needs trimming, room sealed and like @ProDave would buy another her indoors and guests????? only because I was overruled on an induction hob yes, in hindsight I would have provided more (I have 20.20 hindsight).

This is the main reason that fir my retirement house it was a new build and not a renovation like I have been doing for many years. No compromises. We have thick (400mm) walls and the common comment is “your rooms must be small”, but the walls are added to the room size so the outside dimensions are greater. I cannot think of anything with our new build that is a compromise ?. (But I had been planning it fir aver 20 years ?).

Cream, remember it well , my BCO (nice chap), just looked at my roll top bath and said “don’t suppose you fill it right up eh?”

no because if they did not fit you would be in for a heap of trouble. It’s nice when a plan comes together ?

I still use a garden trowel I made as a lad at school metalwork class decades ago ?

Sounds positively pragmatic (that’s a yes) ?

My slates were automatically spaced because we used clips (about 2-3 mm), I guess the gap is for expansion (they can get quite hot being black!).

Yes (could not be me, I wear a mask ?)

Wot @markc said ?

Most .ASHP deliver DHW hotter than UFH so it will run harder. Mine only delivers one temp, set to 48’ in my case but yes it does work harder in colder weather.

Depends if the ground is “made up”, I.e. new ground?, if it’s been walked on for years and not been disturbed it won’t need loads of sub base.

Pete, my electrician is Solar qualified, does a lot round our area, can get you his number if you need it ?

It will but will give you only 125mm thick brickwork per side of the external flue walls, you will need to then corbel the brickwork on each side to support the sides above ?

No, I have 200mm also ?

Yes No, would not pass insulation criteria (at least).
