Is the system not just similar to a gravity fed hot water cylinder from a (solid fuel) back boiler?
That is - it just works because because that's what happens.
No.
Why?
Clipped direct is the best installation method for current carrying capacity (maybe free air is 1A more).
Who knows what will happen? Maybe they will be banned.
No. It might never be needed.
Don't bother then.
Why waste the world's copper?
Is that not a contradiction?
Why then can't you get a 10mm² to the extension CU and a 6mm² back down to the kitchen?
Gas it is.
It's not quite how you first described it.
I don't know what to suggest apart from starting again.
Don't be silly; I am correcting them now.
How has that any relevance when dealing with people saying "would of" or "less" when it should be "fewer" now?
