Smart radiator valves

[slowmotion]

The temperature sensed by a radiator valve probably bears very little resemblance to the bulk temperature in the room. They used to say (late 1970s) that thermostats should be 1.5 metres up the wall, out of sources of heat, away from corners, and away from sunshine. I doubt that Smart radiator valves have got all those messages on board. The salesmen might say different.

Almost certainly going to happen. Can't wait.

I'm a bit under the weather, and I'm freezing when I go to bed, and effectively a second radiator after 3am.

It is digital . The jumper is off or on and the heating is off or on

It’s more a case of in the mornings we heat the whole house unnecessarily. If working at home it’s a similar story. In the evening kids go to bed earlier than us.

Smart valves mean you only heat what you need.

Unless they can make breakfast and clean the house they are not smar enough
Our rads are controlled by a central movable thermostat and as there is normally someone in i doubt i would see any benefits.

They can make a fairly annoying noise.

There are far more irritating noises in my house.

Out of interest, what will a 'smart...i assume digital' thermostat offer over the old thermostatic rad valves ?

No need for me to know really...just interesed.
Grandkids around last night, I prefer to have the stat downstairs set at 16 overnight. As a concession I set it to 17 and closed the windows. Woke up at 3am sweating

Another use case for Smart Pyjamas.

They must be less than 5 years away.

You can, say, program a specific room at 15deg in the morning for an hour, then at 21 in the evening fir 3 hours but off at the weekend.

We installed Pegler iTerrier TRVs a couple of years ago but I have just removed them, too fiddly to program and adjust. If i was hell bent on an electronic TRV solution I would go for a proper central control wireless solution like EvoHome but it is seriously expensive.

So we are back to standard TRV and I am going to get a second zone installed in the central heating pipe work to stop the upstairs heating during the day, my wife works from home and I cannot bear the waste of heating upstairs all day. I would expect the zone 2 central heating to be about £300 all in, it may well not pay for itself in a reasonable timeframe but I will feel better wasting less natural gas so I thinks it’s worth it.

Those Honeywell electronic ones cost about £50 each, so it would cost me £600 in materials to buy one for each radiator , plus i presume i would need to pay someone to install them and set the whole system up.
How long will it take to recoup my outlay?
My problem with new tech is that it gets obsolete too quick and the app stops being supported. My 5 year old smart tv is already no longer being supported, what chance the honeywell app goes the same way?

They suggest 31% saving. Let’s assume it’s being over-egged and call it 15%. Look at your heating bill and work it out.

Depends on your heating costs.

I didn't pay anyone to install my smarter valve (but still not wifi or smart home). I think I just took the top off the old thermostatic valve and screwed or clipped the new smart valve control on top. I may have checked the manual online carefully before purchase to make sure it was compatible, as if it wasn't, then I guess it would mean draining the heating system, changing the valve body and refilling.

I wouldn't buy any "smart home" kit that doesn't have some standard interface. Worst case, I could probably make my own app or a controller with some sort of Pi or Arduino kit, or someone else probably already has and I could copy it.
