Are these as good as they say, ie save on bills? Anyone got experience??


Only installed mine during the summer so haven't had any real use out of them yet. However, I like the fact that individual rads will turn on for as long as is needed, get the room up to temp quickly and turn back off. With some scheduling setup, I can have just the bedrooms turned on during the night and keep downstairs off.

What I like about them (not yet bought them but plan to) is that they're independent of the boiler. So you can use whatever thermostat, boiler control you want and add these on. Clearly you need to leave the boiler on most of the time and let these TRVs control the water flow, but I plan on using this in conjunction with Hive and it should all work fine

So how do you stop downstairs heating when upstairs is on or vice versa? Only way I can think is fitting one to every radiator. That's 14 rads for me - £560 with this offer. I can't decide if that's worth the outlay or not..
No reason why not. Hive will control the boiler - on/off essentially. Probably off between 11pm and 6am. When it comes on, set the thermostat to an arbitrary number, say 25c so it'll always remain on. Then the Tado TRVs will demand the boiler fires or not. Hopefully, most of the time, the amount of times it asks the boiler to fire will be minimal as only 1 or 2 rads will ever need to be on at the same time

That is the downside. I went for a quad pack when it was on offer and put it in the 3 bedrooms and the lounge which are the most used and building it up from there. I think you would have to stick with them being manual for a bit - or if you have the thermostat, keep that in the general area where there are no smart valves. If the rest of the heating comes on, those with smart valves only turn on if they reach the temperature that has been set.

Yeah - 14 rads is a lot. We have 4, plus 2 bathroom towel heaters off the boiler but I'll leave those on low. With 14 rads, I think I'd be a really boring loser and spend this winter turning them on and off manually and work out the cost savings. I did that with my mini house of 4 rads and noticed the gas usage and bills plummet, but it was a hassle turning them on and off twice a day.

I think it just means you control boiler with your hive thermostat and the Tado to control your TRVs. Shame the Hive TRVs were rubbish as I prefer one system to control everything.

I have the vertical mount ones on 2 rads They have a tendancy to read higher than the room temperature as they are affected by heat from the pipes etc. This causes them to switch off sooner than you may want then back on again when the pipes cool off. People say the horizontal ones are a bit better but can't comment on this.

There’s a function on the app to offset the temp for each one
chugerblug09/09/2019 13:14

Better if it’s all Tado, in conjunction with the room stat and extension kit, these radiator stats can turn the boiler on if the temp drops in a single room. That means if there’s a smart TRV on every radiator, you can heat rooms individually.
Nicolidus09/09/2019 13:40

Yes but this is not a proper solution as the temperature when the heating is off will then read low and cause the heating to switch on before you need it. The problem is the sensor is too close to the heat source. Someone suggested if they had a active and inactive offset adjustment this could help but it has yet to be implemented
guildfordhighstreet09/09/2019 12:53

Yes, they are brilliant and we compared 2017 without TADO to 2018 with Tado and we saved a lot, not mention the comfort of use, voice control and air quality. Brilliant system, I can't even imagine living without it.

If you don't want to roll out to 14 rads, you can pick and choose your most important rooms, and the rest of the rads can just have dumb TRVs.

So you also like conventional TRV's, as they also do what you've described.
guildfordhighstreet09/09/2019 12:53

I know I have saved just based on previous behaviour (previous behaviour usually indicates future behaviour), lots of times we go out and forget to turn heating off which led to disputes and wasted money. Geofencing helped with this (V3 version)

I have two Tado devices which replace the existing system (Ground / 1st & 2nd) so goes with the intended original design, I turn off ground floor after specific time cos it gets cold and there's no point heating it when I'm sleeping, the customizable settings allows me to automate so I don't have to do anything.

I believe that having multiple TRVs means better savings but would take many years to get your money back and takes you back to 1940s when you only heated one room, more realistic to do per floor and pay a bit more, especially when you go downstairs to bathroom for toilet in the night and your freezing your nuts off for the sake of a few pence (or wanting to switch rooms and then feel very cold). It's just not worth it imo.

For insurance purposes set your default away temperature to 10 degrees for minimums to avoid pipes freezing and then bursting.

I keep temperature at 19.4 degrees which at the moment is my sweat spot. Daughter's room or floor can be set to 20-22 degrees.

Also 23 degrees or higher is too hot, ideal temperature sits between 18-23 degrees.

Good deal btw

In an ideal world yes, the whole thing would be one brand. But if you already have Hive or similar, or can’t afford replacing it, I think adding these TRVs still works nicely.

You just have to make sure your boiler has a bypass loop, or you leave one radiator without a TRV (mechanical or electronic).

Why not just get hive ones ?
I don't know how many you need but if you buy 5 from hive you get a discount so 5 are £199 so basically the same price as these.

Half tempted to get some if these...

I was looking at hive as I've already got the hub and thermostat, but lots of negative comments out there. Apparently the Heating on demand still doesn't work, which for me is a crucial part of the TRV.

I've got the Hive TRVS and they work exactly how they're meant to.

I guess its hit or miss with them though.
Sorry for the ignorance, but how do these work independent of Hive active heating?
The Hive thermostat is connected via the receiver to the boiler (Combi) to call for heat, but how does the Tado TRV request heat from the boiler?

Do i need the Tado bridge which would sync with the Hive receiver?
Hi, i got the hive on prime day, haven’t got it installed yet as we have honeywell system already but that seems rubbish so far. Can anyone confirm that these will work with HiVe? I will need to get 7 of them for all rooms. So not overly expensive but not cheap either. Any thoughts and experience in having both hive as your thermostat and tado as ur smart rad controls and any quirks or problems with using two different systems?

I read the comments above and do agree that it shouldn’t cause problems coz technically rads can demand hot water from boiler but am no plumber/gas engineer etc so no idea.

After owning this for a month I have to downgrade my review as there would seem to be a very basic design flaw with the thermostat and its ability to record the correct temperature in the room.

The room in which the radiator thermostat is located never seemed to be getting as warm as the thermostat was reporting, so I used a high quality digital thermometer to record the temperature in the room independently. The thermostat seems to record the approximately correct ambient temperature of the room when the radiator is off, but as it's located right next to the heat source, it heats up and records a far higher temperature when the radiator is on. For example. the heating is currently on and I am recording a (correct) ambient temperature of 19C in the room with the thermometer, while the thermostat is recording a temperature of 27C, a huge discrepancy. I can manually apply an offset of -8C via the app so that the thermostat thinks it's the correct temperature at the current moment, but this means that when the radiator is off and the thermostat is recording approximately the correct temperature, it thinks that the room is 8C colder than it actually is, which messes with the trigger to switch on the thermostat (also, the degree by which the thermostat misrecords the temperature is not linear and increases the longer the heating is on and the more the thermostat heats up, so the amount of offset changes considerably depending on how much the thermostat has been heated by the radiator).

This would seem to be a fundamental design flaw with the thermostat. I contacted Tado customer services, who replied:

"Your Smart Radiator Thermostat might be located in an area where the heat from the radiator gets trapped. Therefore, it is unable to correctly measure the room temperature.

There are two settings you can change to counter this:

1. Set an offset value for the measuring device, or

2. Select a different device to measure the temperature of the room."

I've attached a picture to show the position of the thermostat - it would seem to be a standard placement for a radiator thermostat. The option of applying an offset doesn't really work because of the reasons outlined above, and the second option means buying an expensive (currently price £120) wall thermostat merely to get the radiator thermostat to function correctly.

I'm surprised this problem hasn't been pointed out in other reviews so posting here.

The only thing you might want to consider is that the servos turning the water supply on and off are fairly loud and might disturb you if used in a bedroom with a light sleeper.

That's not the best review but I have read others who say they work ok.
I keep forgetting I don't use the Hive app for my hive products I have all my bulbs, Plugs & Motion sensor connected directly with my SmartThings hub only my thermostat connects to the hive hub but even with that I still use SmartThings to control it.
All the problems he's getting are software related as the hive app is very basic and needs a far greater rule engine.
I've seen screenshots off people who have the hive TRV's connected through SmartThings and are working great and can call for heat independently as well as displaying the correct info.
That doesn't help people who only have Hive though I guess
Is SmartThings the samsung product as i be interested if it works with Hive?

You must be very lucky, as i returned all my Hive TRVs, as they would not work as planned and switching to Manual sort of helped but thats defeats the purpose of getting a smart TRV. So your TRV switch the rads on straight away or you have to wait upto 30mins and hope for the best? I like to buy the Hive TRVs in the future to keep to one system to control everything, but how long do you wait for things to get fixed? So tempted to get this instead since winter is coming.
I can't see how these can really make that much of a saving over a well setup manual TRV system. A small adjustment on your manual TRV is all that's required here and there, to get the level of comfort you require, which takes a few seconds to do.

Seems like an over engineered solution to me.

I cant say it's been that much of a saving.

But it's nice to be able to have the heat turn on automatically when we are heading home (which could be at various times, rather than just on a timer), and zone it so the heating is only on downstairs, then half an hour before the kids go up to bed the radiators in their bedrooms turn on, and then a half hour before we go to bed the radiators downstairs turn off and the bedroom one comes one. With manual TRVs the heating would be on in the bedrooms all day if I didn't manually go around and turn them off because I work from home so I want heating downstairs during the day.

Saves me going and turning all the bedroom TRVS off upstairs in the morning and remembering to turn them back on before bedtime.

Plus going out of the door and the heating automatically goes off is nice.

And they can call for the boiler to turn on as well, so if downstairs is ok but one of the bedrooms is really cold, then the TRV can tell the boiler to turn on and just heat that radiator up.

So it's more of a time saving fun gadget rather than a money saving one in my experience.

Then again, in our little house we only needed 5. I'm not sure I'd bother if we needed 14 of them!

Agree with this. the outlay for most houses would be quite large and doesn't really offer much above standard set up TRVs, but introduces new complexities (batteries, temp interference from radiator, connectivity, electrical parts to break down etc)

We've got 10 room radiators and 2 bathroom radiators and feel like this would be an expensive solution to supply and fit and then keep up with batteries on. Reports suggest batteries last 6 months but you cant use rechargeable so it seems wasteful chucking away 24 batteries a year.
