If you already have a TRV then this simply screws on to the existing valve. If you have standard radiator valves then you would need to drain, fit a trv and then mount the tado valve head

You can also order a freezer kit, £17 from CPC so no draining required.. cpc.farnell.com/arc…825

These are just the TRVs; you also need a bunch of other kit, such as gateway, extension kit and a minimum of one smart thermostat. I got this for £150, deactivated the timer clock on the boiler and made my money back within 12 months on heating savings; I used 30% less gas for heating over that period. If your CH system already has TRV bodies with manual heads, it’s likely to be a straightforward swap. If they don’t have TRV bodies, but if they’re not compatible or if the spindle is stuck (WD40 may fix that), you’re looking at £15 hardware cost per TRV.

Pretty sure you don't need the smart thermostat. I had it but then got these TRVs and now it just sits there unused.

Can't say if all setups are the same but I didn't have to for mine. Was replacing non smart TRVs. Took the old ones off, used the relevant adapter (was included) and pushed these on. Had one stubborn one to take off and after that, the rest took less than 5 minutes each. Around 20 minutes to do all 4.

Your _any_ is quite misleading. Actually, no. Plus in case of geofencing, even without subscription, it still gives notification for manual change.
Obviously, core functions and scheduling don't require any subscription.
I don't use geofencing, and dont pay. got every Rad in my house with tado. works brilliantly
I find it really hard to see the benefit, I've thermostatic valves and two zones on my nest system, surely having so many different controls will result in the system confusing itself. Tbh it doesn't take alot to confuse me. Cheers not voted either way

Do you find the TRVs are noisy when they open and close? That's what is holding me back.
If you don’t have a smart thermostat as well as these TRVs, the TRVs can’t ‘call’ the boiler to turn on. The way they work is that they send the signal to the smart thermostat, which in turn tells the extension kit connected to the boiler to turn on.

Most heating systems don’t have zones so you can’t have two thermostats.

This also allows more flexibility if that’s what you need
Works out at £37.5 per TRV..full price is £59 - to go withTado or not is a different question, this is a great deal if you’re after these, not seen anything close to this on a per rad price for a while.

They make a bit of noise, but it’s is purely subjective and it’s like a second or two. I find it strangely satisfying, my kids say it’s not a problem. My youngest head is less than 10 inches away from one of these when he’s in bed. Give it a go, and it you think it’s an issue return it to the retailer under the return policy.

The temperature sensor on these measures the temperature right at TRV level, which is not always ideal and may not reflect the temperature in the room you’re trying to heat to the set temperature. A smart thermostat measures the temperature in the room wherever you place the thermostat, and is more accurate to a tenth of degree Celsius whereas the TVRs can only be set to 1 degree Celsius.

One of my TRVs is fitted in a radiator enclosure and the TVR temperature is way off compared to the temperature in the room. My other TRV is fitted above draughty floorboards which means it is not representative of the temperature in the room. A third tvr is fitted in an attic room under the eaves, with heat from lower floors rising which contributes to the room temperature. The TVR temp sensor is not designed for such real-life situations. The TRVs in my kids rooms which are next to each other, are set in one zone and on one schedule, which is where the smart thermostat also comes in.

Fitting them is easy, unless all TRVs are different makes, but Tado has excellent DIY instructions, plus an excellent customer service to boot.

The app has a setting for each TRV where you can set a negative or positive offset. I agree that the readings are off. I happen to have Hue motion sensors in most rooms so used the temperature reading off that to align it. For me it was an offset of minus 3.

Agreed on the Tado CS. Had an odd configuration issue recently, called the out of hours emergency line and has a phone call back in 10 minutes and they remotely fixed it.

I have a "dumb" thermostat in the corridor (Almost next to the entry and close to a radiator) which is far from ideal. I have fitted 2x Smart Radiator Thermostats in the living room but the problem is these aren't able to call for heating to a dumb thermostat.
Are you saying if I replace it with Tado Thermostat, these would be able to call the boiler to turn on regardless of the temp in the corridor where it would be mounted?

Correct, but you are likely to need a Tado extension kit. This connects to either the boiler or replaces the timer switch. I connected mine to the boiler, so my system is completely wireless.
I’m assuming you have the starter kit (hub) as well?
Edited by: "Nicolidus" 23rd Nov 2019
Question for the informed. I have heatmiser and don’t want to change that. But I have a couple of bedrooms which don’t heat thoroughly with the TRV turned up to full. Seems the TRV’s shut off before the entire room is heated. Can I add one of these TRV’s and set the temperature to allow the entire room to heat up? If so what exactly will I need?

Timing / scheduling would be taken care off by the heatmiser.

Do I really need the extension kit?

If I were you, I’d just unscrew the TRV from the top of the valve, leaving it open fully. See if that solves the problem - if not, save your money and spend it on new radiators that give off more heat.

The Tado smart thermostat cannot be a like for like replacement for the ones you have, unless you replace your timer switch with the extension kit. I decided to wire the extension kit to the boiler so I could get rid of the old thermostat and the timer switch. I tried to swap my old style thermostat with a Tado smart one and blew it up, then did more research and realised the error of my ways!
Hmmm.
Both the thermostat and programmer are wired, why would I need the extension kit?

Thanks, I have done that. Leaving the TRV off results in a room that is too hot. Not comfortable at all, which leads me to think that the Radiators are sized correctly but the current TRV’s aren’t allowing the whole room to heat correctly before they cut the heating. Is one of these type of TRV’s a solution?

Not sure if I’m following you correctly WorldlyTraveller but, my Tado smart thermostat is connected directly to the boiler with a wire. If you disconnect the thermostat then what’s controlling the boiler? The boiler is not wireless (as with most boilers). If you’ve disconnected the thermostat, I’m assuming the radiators force the boiler off by turning off each radiator when the desired temperature is attained?

I’m sure the Tado radiator thermostats don’t connect to the boiler directly as I have one already installed. They do provide better efficiency as they will directly communicate wirelessly to the main Tado thermostat to switch the heating on or off.

Im looking to buy some more thermostat valves to control my heating with greater efficiency and balance my radiators.

The actual valve size doesn’t change with these - it just automates the opening and closing and allows remote control. To buy all the bits to this system to make the TRVs work will be expensive, it would be cheaper to buy new manual TRVs - now that you’ve established that your rads are fine.
Shame this deal isn’t on the horizontal version. I guess I could just use there. Have 4 and want another 4. Hoping amazon drop the price of them

Thanks, my thoughts were more to the fact that the thermostats on my current TRV’s were statically defined, with no ability to change at what temp the TRV closes. I hoped that with these ones I could better control at what temperature the valves would function, allowing them to stay open longer, thereby heating the entire room. I don’t need any of the heat/hot water scheduling so was hoping I could just get one TRV and one room stat that I could fit in one room, and then control the heating of that room independently from the rest of the heating. I would need the ability to control boiler etc. Would that be feasible?

I’m pretty sure you have to pair a smart thermostat with the hub before it will allow you to pair a TRV. It might be better to try to find a standalone TRV brand that can work independently.

Ah, that's interesting, didn't realise the valves could communicate with a wired thermostat. For me, it's the extension kit that is controlling the boiler.

This is one thing that confuses me as Tado sell the bridge and Valves as a set without the extension kit or thermostat. My assumption was that you would have to buy the extension kit.
I’m guessing a bit, but I think the starter kit you mentioned will allow you to control the TRVs when your boiler turns on and off the traditional way. So, no way for the TRVs to call the boiler without having the smart thermostat.
