Absolutely spot on this Allen! Thanks again for another great video.

Alan, I've been waiting for months for a friend to install, but with your help I think I can manage it myself. Haven't got the original instructions for the boiler, but I'll go up in the loft tomorrow and see if I can work it out. Fingers crossed.

Have to say butty this is one of the best videos I have seen on this subject simply put and straight to the point well done

Hi Allen, brilliant video and easy explained 👍 thanks mate

Another great well explained video. Thanks again.

Liked your explainations very clear and understood straight away.

Very clear Allen. Tks.

I used your video to replace my old controller. Excellent video. Cheers😊

Ad my house for 3 years now and boiler is on all the time and cost me a fortune so iv hardly switched it on just used it for hot water. Watching your vid has now convinced me to get a thermostat. It never had one.

Hi Allen. Great video. You did mention you would expalin the 2 different wiring methods for the stat. You used potential free set up and the other was a 230v switched live. Cheers

Excellent vedio

Thanks good men you explain good

You are the best

Great video as usual Allen. I would recommend buying the EU version (V3) of the TADO, not the UK Version to use on combi boilers, so that it can be wired in via OpenTherm, E-Bus etc to enable the boiler to make use of Load/Weather Comp. It just seams strange that TADO dropped OpenTherm from their UK versions as not many installers either used it or understood it.

Hi Allen - thank you for all those great videos. I have ideal boiler combi ESP1 35 with a dual zone ESI thermostat but I want the Tado thermostat instead. Do you think you can do a quick video showing us how to do it? I know lots of people that will love to see that video.😊 thank you

Thank you! So basically two wires as a permanent live from the boiler to the tado block & the link wire is just a switch from the Tado system to turn heating on or of via the app/thermostat! Its a shame in this wireless age it needs the complication needing to be plugged into the router. good video tho!

Thanks for info on thermostat wiring , Quick question is there any power at the CH Com & Ch Open as my boiler connections at the link do not call for any power at these connections .

Hi Allen. Thanks for the great video. I been installing these for a while now. I think you skipped the configuration part. Which is the worst bit of the installation. For Combi boiler you have to disable the hot water function. Other wise it won’t work. It works fine with S plan and Y plan. But it’s a nightmare on Combi boiler. I think I will go back to hive, which is more easy to install.

Thanks Allen, i followed everything but was puzzled when you got to the plug 21 wire connection. Did you take out the original wire connection that you did previously in the video

Thanks Great

Exellent sir thanku

This is great, thanks! One question I do have. As I have an old receiver I can just swap it out with the Tado, however there is an earth wire in the old unit, Im wondering if theres somewhere I could put it (other than just crimp-lugging it to wall inside the unit or inside the unit itself) Cheers!

perfect ! another subs. here ! just a wee question, can u put Tado receiver to replace old wired thermostat ( combi builder ) ? i have 2x zones and set up 1x wired Tado already, just thinking :) thanks ! !

Just a quick question about the existing wall room thermostat, would this be rendered useless or would it need to be set to full? Also, the timer on the boiler would this need to be set to constant? I have a Worcester Greenstar 30Si Combi... TY

Hi Allen. Do you have any videos or advice on fitting this Tado v3+ kit to a Worcester Greenstar 4000? Completely new install no previous controls in house. Thanks!

Hi Allen, I have a Glow Worm Betacom 2 boiler, which is presently wired to a 24V room thermostat via the 24V connection on the boiler. There is also a 230V connection on the boiler available also. I have tried to get info from Glow Worm and Tado on how to wire the receiver, but either have given a positive answer. Can you help? Can the receiver be wired to the 24V connections? Good videos - easy to understand. Thanks

Maybe a stubid question but can I use these on underfloor heating. I have 3,wired thermostats for 3 zones. I would like to replace them with smart, programmable thermostats. If not, advice would be appreciated.

Great Video. I have an Ideal Vogue Max combi boiler which is about 2 years old and is run via Halo thermostat set up. Would I be able to install just the Tado Smart thermostat valves and Internet bridge to some of my radiators without the need of installing the Tado hub? I have read that as long as my boiler is compatible with Opentherm and 240v, my Ideal boiler will work? Can you please advise? Thanks so much, Ian

Im using the VIESSMANN Vitodens 200-W B2HB and installed a thermostat in each room. I replaced two of them with the Tado thermostat (wired) and I’m planning to replace all the others in the future. Do I need a additional extension kit or is this enough? It’s not fully understandable for me what’s the benefits of a extension kit.

Allen please also cover wiring this unit into a regular boiler , preferably old school boiler that can’t use the cables as they normally have a timer in the airing Cupboard such as with an old manual timer to smart timer on s plan

Ha, I did that about 2 weeks ago but a Potterton Suprima and EP3002 (S-Plan). As an aside it took me ages to find out what NO and NC meant, Normally Open and Normally Closed. I would be cautions showing the Apple Home kit id .... Also, you can buy the Myson TRV body on it's own to fit to Rads, about £6.50p each.

Allen, I see from the wiring diagram you showed for combi boilers that the com is also connected to live although this is not connected in your video. Am I missing something? Thanks for a great video. Les

I just bought a house and I have a Baxxi probably was in house since 2010 , is it possible to put smart thermostat and make it smart for hot water and heating the house ?

Hi, I was going to install the Tado smart wireless thermostat on my Vaillant Ecotec 831 boiler however I spoke with an engineer who said while it can be done on the Ecotec boilers it will not run as efficiently as they would using their own controllers. This is due to vaillant having their own Ebus chip and third party controllers can only control the boiler to be on or off rather than gradual heat control, this wasn't always the case with the previous vr65 which I think were opentherm but since the vr66 this seems to not work aswell with third party. Because of this I decided to only purchase the Tado radiator thermostats which come with the bridge in order to run those as an extra while keeping my Vaillant controller. Please can you or anyone else confirm this to be true?

Hi Allen I have brought a Tado starter kit v3+ wireless smart thermostat for my worcester greenstar 28cdi. I am going around in circles with tado trying to get the installation guide from them and ripping my hair out as was told that this would modulate the boiler through the EMS bus. Is there any chance this is something you could help me with or do you know someone in Cornwall who knows how to wire this? Many Thanks, Scot

💕💕💕

Wiring a Salus Rx10rf to my boiler, and want to know if the com and no are volt free connections in the link you removed, I’m worried that they might be switched live, my boiler is Worcester CDI25 and I’m not sure if the link is volt free, don’t want to blow my boiler or the controller

As an end user I can confirm it co exists happily with weather comp on Baxi 600 and 800 kit. The absence of Open Therm on the UK product is frustrating.

Hi Allan. Can you show how us how to link the thermostat to the receiver without wifi. I don't have wifi in the house at the moment. Thanks

Hi Allen, Can you do a video on how to connect Tado wireless to Ideal Logic ES1?

Would this work on vokera Unica boiler?

Hi , so does it not matter which way the com & no wires are fitted ?

Hi when you turn off the heating does the hot water remain?

worth mentioning that you can configure tado to have 2 zones and hot water control if you use an extra smart thermostat and have it hard wired to one zone valve. The other thermostat can be wireless and use the extensions channel.

Hi Allen, is easy to replace a NEST with Tado? I really need zoning to save money.

Hi could you please explain how to connect tado v3+ to glow worm flexicom cx 30. I imagine every single brand have a different connection.

Can you not just replace the old programmer head with the smart receiver? My boiler is brand new navien ncb300

Can anyone help me out? I have a very old Raven heat boiler and I can’t find the manual. It has a live in and a live out plug which is not a problem. The old thermostat receiver is wired into the live out so that makes sense. However The common and the NO are wired into a plug labelled ‘room stat’ which again makes sense however they are light grey and dark grey not grey and black and in the receiver itself they are not very helpful. The receiver labels are N/L/1/2/3/4 with the light grey in 1 and the dark grey in 3

Hi there, I have a honeywell wireless stat at the moment, with a neutral, live and an A and a B wire between the receiver and my viessman vitedens 200 boiler. Will I be able to use the existing wiring coming out of the boiler or will I need to change it. Thanks

What viesmann model is the one in the video?

Can you make a video for TADO EU model for Opentherm and HotWater Priority on a System Boiler with water tank! Apparently possible but nobody is able to prove it. Tado claims not possible?

I have a pottery on he 28 that is wired to a programmer also going into a wired thermostat . Is it possible to remove these and just go wireless straight to the boiler ? With wireless thermostats etc

Hi guys, I'm looking to get Tado but am getting a bit confused from the comments. Are people saying that the UK version doesn't have load compensation i.e that it doesn't actually modulate the boiler?

Hi, great info but can you use this Tado on a combi boiler with no controller but an upstairs and downstairs thermostat already wired in, Thanks, Malcolm

Hi .. how would I connect a Sangamo wireless thermostat to a vaillant eco Tec 32 . Thanks

why dont used wifi property by vicare ?

Genuinely made me think, why bother?

Good afternoon can kindly help me with wiring a tado v3 smart thermomstat into my vaillant ecotec plus 825 please. Our v smart thermostat has given up and I purchased this one but I can’t for the life of me understand the wiring diagram. If someone could help I would be very grateful. I will attach a pic of the boiler connections for reference. My old connections went into the bus connector on the boiler and into the gateway which I haven’t disconnected yet.

Needs to be a case with screws on the front. Sick of twats putting controls in positions where you can’t get the screws undone

17:14 ypu didnt show how you put the lid of the extension kit onto its base:(

Removing front cover doesn't have anything to do with the gas and or combustion Chambers surely.? Most sparks end up wiring these boilers up and not many of them will be gas safe.

I got excited when I saw this but then I looked at how my Oil Boiler is wired in and I'm utterly befuddled! God knows who wired it but it does not look like any of this

Tado is sold as a diy smart thermostat, every video you make on a boiler you say you must be gas safe registered to take cover off the boiler, to install the tado the cover of the boiler has to come off to get to wiring so are you not contradicting yourself by showing a diy install thermostat where the diy’er has to take the cover off

Welcome to the amazing UK where combi boilers are a new thing apparently... this country is ancient minded and stuck in the 60's. Nowhere in continental Europe is to find system boilers or standard or any kind of open system!!! Horrible!
