Did anyone else know that it is Boiler Switch On Week?

Well its not functional is it! Its also not efficient!

You carry on arguing but you are still wrong.

I don't know who you are going to argue with though, maybe your other half of a brain?

bellwire lighting could be functional, safe and not crap.

some things aren't worth replying to.

It could be either. I've seen bellwire fed lights in a pub with the wire draped down the wall and an uninsulated chocblock about 3' from the ground. That's crap. Or the bellwire could be all out of reach where it doesn't need double insulation & is not in any way crap.

bellwire is both

Hardly complex. Each timer/stat simply switches a valve. All the valve limit switches are connected together, so any open valve energises the boiler.

The valves waste very little energy, they are rated at only 6W each and are only energised when heat is required, so unlikely to be totally wasted energy anyway - it's a tiny bit more heat ending up in the house.

I had TRVs originally and making each room its own zone is far more flexible.

Remember the Ideal Mexico?

That had no pump over run and did not need a bypass:-)

Of course any cat owner will tell you that this does not matter as all doors must be left open at all times so all the rooms are the same temperature:-)

No, the doors must be left open at all times so the cat can walk from a warm room to a cold room because he's too hot, then ask you to turn the heating up in the cold room until it's warmer than the warm room...

I've not had hands on a Hive system with radiator valves but from the manuals and comments online I thought one could only adjust them one by one. What I want - and should have made clearer - is the means to adjust several at once. Ideally several that are not all set at the same temperature but move up and down in step. If it means going through several it won't get done.

The need to replace batteries every so often also militates against them for the user I have in mind. (The more so if, as some users seem to find, 2 years from one set of batteries is optimistic.)

Alexa routines?

No! My ignorance is almost immaculate. It's not just that I'd never heard of the Ideal Mexico. When I Googled for it I fully expected to see results from local waxing centres.

We have three. They are not normally allowed upstairs and only the kitten is fast enough to dive through when someone goes in or out.

Quite. Not ideal, not to code but could easily be perfectly functional and (therefore) not cr@p as a means to an end.

Again, of course it is.

The problem with Dennis is he is a left brainer and so has to do, and can only consider, everything strictly 'by the book', even when that isn't part of the question.

While one incompetent person may have drafted the legislation an incompetent assembly passed it without realising what they had signed up to.

On a cold frosty morning and the TRV is fully open it cannot tell the boiler and the pump to switch on to provide heat. The room remains cold.

On a cold frosty morning and the temperature is low a room thermostat can tell the boiler and the pump to switch on.

That is, of course, the more charitable explanation. One has, then, to assume that the fact that many of the beneficiaries were DUP supporters and patrons was pure coincidence.

That is to assume that there is any point in the boiler being off in the heating season.

Now with LEDs we don't need anywhere near that. 240W of LEDs is equivalent to a bit under 2kW of filament light, and efficacy improvements are driving that figure up over time. Since pretty much every house now has 2 or more lighting circuits, that's around 4kW, more than enough.

If everything is up to temperature it stops the boiler cycling which saves fuel and wear.

You know it makes sense.

So does sitting at home in your overcoat all day to save the climate - but I don't do it.
