Forgive my perhaps impolite intrusion on the current conversation, but I'm researching the use of the VR33 on valliant 637 and I notice that back in early 2017 you were able to provide photos of the set up of your board. A bit cheeky I know, but I wondered if you still could provide me with some photo's?
Many thanks

22! id be walking around in my pants all the time!
I noticed the other day, during a particularly cold spell, my wife had whacked the thermostat up to 27!

Thankfully I'm the only one that can control the thermostat remotely from my phone so I put pay to that.

Well, I put myself in it now. I am trustee and director of a medium sized community charity that owns a large centre: 2 massive gas boilers heating 30 rooms, 70-80 radiators, currently using 3 manual stats and a sweaty old bloke who runs around 8 times a week twiddling TRVs when the various rooms are in use or not.
Our gas and electric bill tops £12k a year.
So I was talking up the smart TRV system to our caretaker and wondered if it was feasible to fit at our centre? I'd imagine we'd be looking at 3+ controllers plus range extenders.
Anyone have any thoughts?
Damage to trv heads a issue?

Any electronic actuator is fragile to vandalism and general damage.

In that situation, id go Honeywell. It's range, settings and proven reliability.

Evohomeshop sell actuator guards/covers too.

Can you disable itrvs with wiser? So people can't play with them and turn the heating up?

When I had it you couldn't, evohome can though, that might be a issue dependant on who's using the premises, (kids or adults etc).

Yes you can, sort of. When the heating is off for that room playing with the TRV will not turn it on, but when the heating is on then you can turn up the temperature.

There's an option in the devices section on the app where you can disable the device so the controls don't work - it shoudl still follow the schedule though I guess.

The main problems encountered (with Wiser) have been:

ii) The batteries supplied with the valves are utter garbage, replacing them with better quality Lithium AA cells has paid dividends.
What benefit did you see from better batteries? I have one TRV that seems to be eating them a lot faster than the other TRVs, It's got through a set and a half while all off the other TRVs aren't even showing less than full battery on their original ones. Does it help with valve actuation as I think I'm having shut-off issues where the TRV body/valve isn't fully closing, so when another zone calls for heat, water is getting through and the non-requesting rad is getting warm.

Oh, and any recommendations for Lithium AA batteries?

I have not done the battery change and it has been OK so far. The reasoning behind the changes is the supplied batteries are very cheap so when asked to supply peak current will struggle (due to higher internal resistance) and therefore not last as long. I can see this being a problem in particular if your valves are older so take more force to move.

Certainly for my colleague who has made the change it has sorted out a few rooms where operation was previously sketchy

Yes, TRV damage might be an issue. Common ground floor rooms and passages have a huge traffic flow, we have upwards of 100 kids running riot on a weekly basis.
Forgive me but didn't someone say that evo doesn;t have range extenders? How would the practical layout look, multiple controllers?

this, plus people will nick the TRVs if they realise they're £50 each

That's kind of my question - if evo et al won't cut it, what would?

Update on the idea touch connect - it’s rubbish.

Optimisation (telling the heating to be at that temperature at that time) doesn’t work and the system is so flakey due to supposed issues with the cloud that it may as well be a dumb thermostat.

It’s going back and I’m looking at something else...

Has wider improved?

Shall I just get a nest?

I no longer own a B&B with lots of rooms, but own a 17th century stone walled cottage - 7 radiators and a combi instead of 12 radiators and a boiler and water tank combo...
