I blame auto correct 🤷‍♂️(plus I wanted to see if you were awake yet).

I like that analogy 👍, why my build had a 4Kw ASHP.

It’s corrugated and copper is quite soft so it can be bent by hand and remain at that bend rather than be “rubbery”

Welcome to THE building forum, bring on the questions

I don’t think so, the other flexi,s are rubber tube inside protective mesh and from my experience it’s the rubber or rubber join that fails. These are corrugated copper.

Anyone used these (I haven’t). https://www.amazon.co.uk/Flexible-Bendable-Copper-Plumbing-Stick/dp/B01LBHR2LU/ref=sr_1_5?crid=27L6GIFS0EC4C&keywords=flexible+copper+pipe+15mm&qid=1705948803&sprefix=Flexible+copper+pipe%2Caps%2C79&sr=8-5

If you added 100mm I doubt it would be noticed, I have yet to hear of any build being measured after completion (my roof was 100mm over the designed height but no one noticed 🤷‍♂️)

Not necessarily, with my build I designed the rooms then added the wall around them, only adding IWI to an existing build reduces room dimensions.

Yes sorry, very un PC of me 🙄

With my build I wanted induction but was overruled so had to install gas bottles and pipe work etc 🤯

Welcome, +1 the controller for the DHW / ASHP needs tweaking (mine was on 24/7 but only as required driven by the tank stat). Of course you need a double garage, all men do, gives you an excuse to buy cars that DO need a garage.

I too have had them fail and would not used them again.

My ex wife choose an expensive paint for our last house, it was very near magnolia which was a quarter of the price so I used magnolia and she never noticed the difference 🤣.

Yes I think you are correct, I ran my DHW at 48’ and found it fine for all usage but I had a larger DHW tank as blending with cold water was much less. I had a buffer but borderline on being a requirement, however it gave me the chance to instal an immersion for the UFH in case the ASHP or pump etc failed as a short term measure. Siting the DHW tank as central as possible and shortest pipe runs and some in 10mm pipe means less wastage of water and time (=money).

Which is/was tarmac.

Why.?

I have tiled for years but used multi panels on my build and would never go back to tiles 🤷‍♂️

A more simple approach to dhw this thread is about DHW.

But only to take up the slack, don’t pull the rod out of the hole/resin 🤷‍♂️

If you have your BCO on side then do it yourself. I did my own for a full build but got an architect to draw it up on CAD (as I still use paper and pencil 🙄) and frankly he made mistakes I had to correct. Your BCO will help, as mine did.

+1 to resin but make sure all dust is removed from the hole.

I do think that there are so many variables (construction, orientation, ground conditions, etc etc) that no one answer is correct for every situation.

I agree, the bottom panels in wood look better, but not at that cost eh?

I would have thought the underfelt would have dealt with that, that’s what I did with my workshop roof and no condensation.

Not always, my box roofing on my workshop had fixings in the trough as specified (they are not long enough elsewhere) and had rubber sealing washers. I agree that the old nail through fixings for corrugated roofing were used at the peaks.
