temperature valves on all taps

I meant the sort of wooden grille-type covers you get for prettifying rads in houses. Obviously they'll cut down output a lot but in the main area concerned the rads would still cope if the room weren't haemmoraghing heat :-(

You still ought to verify the surface temperatures achieved. It is surprisingly easy to end up with local hotspots.

The idea was to minimize the length of the blended water pipework, because it was a greater legionella hazard. You'd use one TMV to supply a group of fitings.

Hudevad http://www.hudevad.co.uk / and Runtal (now Zehnder?) used to be the main UK suppliers of LST rads. They all looked a bit NHS, 'cos the NHS was the main purchaser. You also had to ensure that any accessible pipework or valves were insulated, which was a PITA if the building was not designed for such special-needs use.a purpose

The application of logic that went into that posting almost reaches Dribble's standards.
Using proper separate taps, with outlets the size of the inlets. Hot tap hot water at 60 deg C Cold tap cold water at 5 deg C Mix to give at any suitable temperature such as say 40 deg C to wash Drain Fill with water at sub 40 deg C to rinse Drain
Using mixer tap at temperature between 5 deg C and say Fill with water at 40 deg C Drain Fill with water at sub 40 deg c to rinse Drain
The usage of water and the energy used is exactly the same in both cases. The key difference is the proper taps without crappy aerators and thermostatic limiting will fill the bowl/sink/bath quicker and give you proper 60 deg C hot water or proper near ice cold water when you need it.
So I say stuff the nanny state, thermostatic taps are yet another bloody stupid foreign idea - about as useful as a fart in a spacesuit or a combi in a typical household.
Of course up in Yorkshire we'd just wash with 5 deg C water.

How poshe! Darn Sarf we'd use 40 deg F, if there was any water to be had.

Either you're being obtuse or I didn't explain clearly. Despite the glaring improbability of the latter I'll give you the benefit of the doubt :-). What I meant was that you could wash your hands under a spray of warm water without filling the basin, using far less water and energy doing so.

That sort of makes sense - apart from the fact the hot water will probably have cooled since the last use, maybe even down to room temperature and all you will get is something slightly warmer than the raw cold supply. Unless you instantly heat at the tap I can't really see water usage falling. Seeing as thermostatic shower valves at hugely greater prices fail to stop an average combi from alternately freezing and near scalding due to "other tap usage" I can't see a 30 quid TMV having much chance. :)

True, but even so the chill effect of a spray is less than that of a running tap so a lot of times people will be happy to wash under the tepid/cool/cold[1] water rather than wait for it to warm up. Even so I think there's room for improvement long-term in the infrastructure: with mains-pressure H & C water supplies and low-consumption spray taps there's no need for 15mm pipework: runs could be in 10mm saving a lot in dead-leg runoff. One could even envision lagged pipe (perhaps lagging ready-fitted on the roll[2]) for convenience and encouragement of installers. Of course that wouldn't happen overnight but it's a direction worth moving in.
I'm just saying that for the relatively modest level of technology and expense[3] it seems like a good water and energy saving measure at a time when the planet we're attempting to conserve for our children could do with all the help it can get in these departments.
[1] and not just Yorkshire-folks: when I were a lad in Wales we'd often wake up to frost on the inside of the windows.
[2] assuming plastic pipework here: again, less cooling and more compatible with current construction practices.
[3] most of the price of taps is markup: compare the prices in posh bathroom showrooms, sheds, Screwfix/Toolstation and on eBay. You can get a quite decent thermostatic shower mixer valve from the online sheds for half the price of a pair of fancy-looking but otherwise bog-standard basin taps.

No, I would have been able to smell one of *their* stupid ideas a mile off, too.
BTW, it *was* a female Labour MP, however disappointing that might be to some of you.
It's useful to be able to predict the likely direction of the stupidies of adherents of different polical parties, because every few years you have to decide which bunch of morons you're going to vote for.
Beside which, slapping-down unthinking, automatic political correctness is more fun than talking about valves.

How do you do that when the leader of the labour party is a Tory and the leader of the Tory party is trying to look like a caring liberal if not actually a socialist?

I think she is trying to stop children and old people getting scolded, what the hell has that got to do with political correctness?

With some difficulty. But at least for a few months more, they each require the support of their MPs to pass new legislation, so identifying their likely herd behaviour is relevant.

It was you I was refering to.

She's prolly rather big on scolding people, being a female MP (of whichever objectionable hue)

nah, its Tory MPs from public schools that are into "scolding".
Arent spellchecks a wonderful thing?
