thermostatic valve?

Not AFAIK. There may be certain circumstances where it is good practice or even a regulation (eg. Hospitals, nurseries, care homes etc.).

Um, I think that's wrong. For baths and bidets water temperature mustn't exceed 48C (not sure of the precise figure but it's thereabouts). If you hot water tank supplies water hotter than that then you must have some sort of thermostatic regulation. Either a thermostatic mixer tap of some sort of thermostatic blending valve to limit HW temperature from the hot tap.

Tim

that's interesting.... do you have a reference to the applicable Building Reg (?) / other legislation? ta jim

I think Rob is right, it only applies in Scotland. I couldn't find it in the English building regs.

If you are in Scotland, it's

Odd that in Scotland all the documents seem to be freely available whereas in England it looks like you have to pay for them (or have I been looking in the wrong place?).

Cheers. I just missed the link.

It would seem that you still have the freedom to scald yourself in England. ;-)

I think you mean "paid for by the English taxpayer"

And long may that be the case. The pleasures of topping up a bath with piping hot water is one that Eurocrats in Brussels would never even begin to appreciate

Yet another reason for not existing there - it's hardly living when you can't top up a bath with piping hot water

Perhaps it's so cold up there that 48C water feels like piping hot :-)

Always fit a TMV. The cylinder water must be over 60C stored. ACV have their cylinder stat with a min of 60C and supply a TMV. They recommend 65C storage.
