The Smart Radiator Thermostat works with a Tado gateway and thermostat/extension kit; it uses your phone’s location to control a room radiator. It turns the heating down when no one is home and starts to pre-heat when it detects the first person returning. Relatively easy to install by unscrewing the thermostatic valve heads and putting these on the bodies, following clear instructions.

(The most tricky thing is to figure out which type valve body your radiator has and whether it will work with one of the included adapter rings. support.tado.com/hc/…583 . Also check that your existing TRV works and the spindle isn’t stuck.)

If you already have a Smart Radiator Thermostat - Starter Kit or a Smart Thermostat - Starter Kit of any version (V2/V3/V3+) then you can supplement these with additional Smart Radiator Thermostats to independently control multiple radiators.

The Tado valves are not compatible with other smart heating systems.

I had a timer-based heating system and TRVs in all rooms, invested in a Tado gateway, the extension kit, and smart thermostat, and cut my gas bill with 25-30% in one year.

Great price for these. Note that these can only replace existing TRVs, and not mechanical valves.

I found out the hard way. Anyone know where you can buy a TRV body angled bracket, but not the head?

Given a new trv cost is around 6 -7 pounds just buy one and sell the head on ebay

the only issue with TADO is you have to subscribe to get some of the benefits and have a hub

How to know if I got a TRV or mechanical valves please, my radiators have water control valve on one side and a temperature control valve (round knob with 1 to 5) on the other end except for the one in the conservatory which has a water control valve on one side and the other side also have the same valve (never tried turning it). and there is no thermostat.

Say for a 3 bed semi the cost is: ~ £1000. Even with a modest saving of 10% you'd save £100/year, so you'd get payoff in 1.5 years. The OP said he saved 25-30% which would save you £250-300/year.

I think they are probably worth considering at least.

not sure how you can guarantee that!

I'd expect it may take a couple of years but should get there. All depends on your heating usage patterns & whether it would make sense to have some rads off for certain periods of time. e.g. I work from home sometimes in a room downstairs, want heating on but don't need any of the upstairs rads on, so that could be 8 or more hours of just heating the downstairs. I've not done the sums but can certainly see a case for them

or you could save the initial install cost (and ongoing subs if applicable) my spending 10 second of your time going into each room upstairs and turning the manual TRV's down yourself on that odd day you worked from home.

that is of course true, but doubt many can be bothered or would remember to do that every time. These are of course a convenience device but far more likely to be effective if you've set it up once & can leave it to only have downstairs rads on during the daytime hours if someone is home for example, that could then apply to weekends as well. You can of course do it manually as you say, just seems less likely to be something I'd ever actually bother to do!
Considering I have five of the Hive ones, I do know for a fact that the cost saving is not going to be anywhere near £100 a year.

I have a three bed semi. I sometimes work at home, and my office is the smallest bedroom. That'll be 6 hours of heating required. The rest of the house is off.

In the morning, the bedroom is on for 1 hour. Again, the rest of the house is off.

In the evening, the living and reception rooms are on for about 5 hours 17:00 - 22:00. Master bedroom comes on at 21:30 and off by 22:30.

Each radiator takes between 20 - 40 minutes to get to full heating effectiveness because, by design, the Hive TRVs will not just open wide and let the heat in, they trickle the heat instead so the room does not overheat. Whether this is the case with Tado I do not know, but there are many of these products and I suspect they will all operate in the same fashion.

Considering the wastage in the time taken to properly open the valve, the training period of the devices (Hive requires 1-4 hours of training per TRV), the boiler efficiency, radiator efficiency, general home insulation...you're not going to get savings to warrant the initial purchase price.

Why then did I fork out for 5 Hive devices? Well, firstly I had no idea of the shambolic introduction period that these things would have to go through (I probably wasted a week's gas having to configure and go through tech support) and pretty much the only thing that isn't 'smart' in my house are the brick walls, so I always wanted to adopt smart TRVs fully knowing the price tag would never be reclaimed by usage. I just like the ability to operate them without being in the house, or hitting a button to heat a room while I'm having a relaxing read of the news on the toilet.

first world problems and all that LOL

I think it all depends on your particular situation and property, I have an Opentherm controller (a Nest V3) controlling my heating. I have the whole house heated to 18 degrees 24/7 even when no one is at home, to keep this constant temperature takes very little through out the day and night according to the usage graph. When I'm at home the nest increases to 20 degrees, this heats all the downstairs (as its semi open plan) but upstairs stays at 18 via manual TRV's which is warm enough for sleeping in, works well for me.

That's not really cost effective or a good idea either. Boilers have a minimum output and it will be a lot higher than heating just 1 radiator, you'll be wasting a lot of gas and putting undue wear and tear on the bolier.

I didn't realise there wasn't a boiler controller linked to these. With the heatboss system it'll turn off the boiler when all the rooms are up to temperature, which should be a bit more effective (of course it's more of an industrial system)

there is a boiler controller linked to these (if installed correctly using the bridge) but that has nothing to do with the minimum power output of a boiler versus the demand of just 1 or 2 radiators.

I've had Tado for years, only basic thermostat and have just ordered 2 Tado TRVs and they will be my first. To your point above, the Tado extension kit (or direct-wired 'stat) just connects to and operates my boiler's relay (on or off). Tado shows up to 3 bars of heat on the app/web with 1 and 2 bars meaning a trickle (triggering the relay on and off) and 3 bars meaning always on. So you always know what it's doing. Therefore Tado is instantly better than a traditional thermostat which only turns off the boiler relay when the temperature has been reached!

In addition to this, Tado learns how long it takes to heat your house and how well your house / room retains the heat. If you schedule the house to be 21 degrees at 6:30am then it will perform a pre-heat in advance based on how cold it is outside and in. It's very clever and this I believe is where Tado completely excels over other systems: it's in their intelligent learning algorithms.

I've purchased these TRVs for my living room which nobody ever goes into Mon-Fri in the morning. I'm confident I'll get my 69 quid back.

I will but that minimum output will be as high as 8kw (if a combi) and to heat a 1kw or 2 kw radiator, the boiler will be switching the flame on and off more often as it wont be able to dissipate the heat fast enough, each ignition and extinguish wastes a lot of gas as the combustion chamber is purged of gas/air each time, as the mechanical gas valve only has a finite number of operations there will also be more wear and tear.

So not the 1 bedroom you stated initially, unless you have a heat only or system boiler I still doubt the boiler can modulate low enough for those 3 still.

It all depends on the building, insulation and type of heating set up prior to installing smart heating. Mine was a timer-based system, 79.9% SAP seasonal efficiency boiler (SEDBUK rating D), with TRVs on most rads in an old 1900s 3-bed house in an area where wall cavity insulation is ill-advised due to the weather. Following Tado installation my annual gas consumption was 27% lower, saving 2 quid shy of £200 for a system that cost me £150. I bought a V2 system with no subs and it works brilliantly. All large rads now have Tado TRVs and I’m getting basic £15 time-based TRVs for 3 smaller rads (ebay.co.uk/itm…221).

It’s a much better investment to bring cost down this way with a smart heating system compared to say an expensive upgrade from a 80% to a 90% efficiency-rated boiler which may save you £70 a year and payback most likely exceeds lifetime of the boiler...
