Enjoyed your Tado videos the fact that it allows TRV zones the chance to draw heat even when the master stat is off is excellent. One issue i have is my bathroom heat often is less than i would like as the system has switched off. Thank you for your efforts 👍
Thanks for the excellent video. I'm still concerned about something: if you've installed Smart TRVs on ALL your radiators and none of them is calling for heat and you raise the temperature of the main Tado thermostat until it calls for heat, does your boiler start while all the valves are closed? Could this not be dangerous (or totally useless at the least)? Or maybe, is the system smart enough to check whether there's always an open valve whenever the main thermostat calls for heat?
So, the best way to prevent this, would be to ensure that your master tado Thermostat is included in one of your heating zones with Tado TRVs. That way, you would never have this problem. Technically, it also should not be a problem for a modern boiler, but I guess some older boilers might not handle it so well.
The radiator in the room where your smart thermostat is located (e.g. the hallway) should not have a TRV, because that radiator is controlled by the thermostat. This applies in general to all central heating systems; the radiator associated with the master thermostat never has a TRV because it doesn't need one. However, if you move the smart thermostat (something that traditional thermostats cant do), then the room into whic you move it should have the TRV set to always open.
@@kasroa Tado does recommend placing TRVs in the room where the main thermostat is: support.tado.com/en/articles/3387257 As explained in the video, this ensures rooms can be heated while the main thermostat room is not being heated. In old ('non-smart') systems, this will not work because indeed the radiator thermostat and room thermostat can't communicate.
Hi - nice video. I have two questions: Is there an issue with distance of the valves from the router and bridge and how long do the valve batteries last and what happens when they die if you are away for an extended period. Thanks.
Hi there! I'm not sure what the absolute maximum range is, however I can tell you we have a three storey house. One of our radiator valves is on the top floor and the bridge is on the ground floor, and we've had no problems with connectivity. Our first set of radiator controllers was installed on January 2018 this year, and the batteries are still showing as good. Additionally the main Thermostat unit was installed November 2017, and is also still good. I'm not sure what would happen if a controller lost power completely. Best guess? The valve would remain in whatever position it was last in, but would likely no longer be capable of calling-for-heat from your boiler. If you don't have a boiler (such as in communal heating situations), then you'll likely be without control until the batteries are replaced.
Hi, you explained that really good. But dose this works without the extansion kit also? I have a wired thermostat in my living room and 3 radiators in the same room. The thermostat controls a pump that is bringing hot water into my radiators. My question is if i instal a smart themostat and smart trv in every room (also in the living room where the thermostat is) will the smart trv call for heat when needed in other rooms even when the living room (where the termostat is) dont need heat? Meaning the termostat will turn on my pump but the living room will not heat beacuse the smart trv will close? Dose this works without the extansio, only with he smart hub a smart thermostat and smart trvs?
My understanding is that yes this should work. If you replace your wired thermostat with a Tado one, but no extension kit, then it will become the 'master controller' for your boiler, and will relay calls for heat from /other/ rooms, even if the one that the thermostat is located in is /not/ currently calling for heat. In such a scenario you are correct in your assessment: Only those TRVs in rooms calling-for-heat will be opened up. This will ensure that the heat is directed only where it is needed, and in turn, help to keep the load being placed on your boiler low. Saves energy and money :)
@@rallicat7362 i contacted tado support. They told me the same like you. It can work like that i just need to set the system to work like this, that the TRVs can call for heat and not only open and close(in my case turn on the pump)I have a wooden pellet heating system that is always on and heat the water for my radiators. So i just need to control the pump so the water can circulate. Thank you for you answare!
This video is excellent. Thanks for taking the time

Hi! Thank you for the nice review! I do have one important question: is it still true that when a zone only has a smart radiator thermostat, you can only change the temperature for that zone in increments of whole degrees? That seems to be a major problem to me, I'd expect to have a granularity of at least half degrees. It also sounds an alarm in my mind because my current smart radiator thermostats from Netatmo have proved to me that when you only have a smart radiator thermostat in a room (and not an additional thermostat too), then it's quite impossible to get accurate temperature estimations for that room (can't call them measurements because the valve is so close to the heat source that it's only guessing the real room temperature). SO what I'm worried about is that being able to change the temperature in increments of whole degrees is basically Tado admitting that they can't get any accurate temperature estimation, that there could be a whole degree difference from reality, which sometimes can be uncomfortable... So has this changed since the time when the video was made, or is it still the same?
You are correct, you only get whole degree adjustment for a zone with only a radiator valve. It's also true that with the valve sat close to the radiator, accurate room readings are a challenge. I get different results in different rooms. In our living room for example, we get pretty good results, with the temperature fairly comfortable. In other rooms it's not so good. However you can make adjustments if you feel the temperature reading is not a true reflection of the room. You can reconfigure the settings of the device with a temperature 'offset' to help ensure the unit is heating the room to the proper level. If you can adjust the offset to ensure your room is actually at a comfortable temperature for you during the times you want, then my advice is simply to let it do it's thing. The primary principle here is that the thermostat will open to allow heating to occur, and will close again when it is not - in this regard as long as you're getting the /comfort/ you seek, then the rest is simply energy saving - and this is where things do actually work pretty well. Finally, I should advise that things seem a little better if you have a modern boiler, and you're able to wire in using 'digital' control. In this regard, the system is able to actually tell the boiler how much heat output is required. As your rooms reach the required temperature, the water flowing around doesn't need to be so hot, so rooms seem to 'settle' better with smart thermostats, since the radiators themselves aren't having to get roasting hot ... which in turn means the radiator valves don't get 'thrown off' so badly :)
Great video, helps a lot. I am trying to decide which direction to go with wireless controls and intend to use the extender to control the hot water too. I do have one question though, I currently have a thermostat with timer controls downstairs and also have one upstairs, being a newer house I think this was a standard set up. This would mean replacing both, can the app control 2 x Thermostats as zones for upstairs and downstairs. [not planning on getting the TRVs to begin with] cheers James
Interesting. Are the controllers wired or wireless? It's possible that if they are wired you'll only need to replace your current thermostats. The best thing to do though is contact Tado and describe your current setup to then in detail. They should be able to advise on the equipment you will need.
Have you or anyone watching wanted to remote switch another device? For instance when the Timer or hand operation is activated on the room thermostat I need to remote switch a smart plug elsewhere in the house.Hard wiring not possible, it seems there is a gap in Tados product range for a smart remote switch.
Hi, is TADO TRV has a heat sensor in a particular side of the TRV head or it detects all around? If it is from particular side is that possible to keep it away from direct heat from the radiator? Perhaps keep it turned away or isolate with reflective screen on the radiator on that side? Do think it will help to detect more accurate air temperature rather than radiator surface?
Great video. I suspect you can only control the TRVs in whole degrees since it would otherwise constantly turn on/off as it bounced around the set temperature. The noise from the Trv motor would be annoying, particularly at night.
You're probably right! It's possible to add a standard Tado Thermostat to a zone, which would add more fine control. I plan to do just that. I'll report back on how things go with the radiator valves afterwards!
Hi, great video. I have a question though. How would these smart TRV's affect the gas central heating system? Will not increase the wear of the system if it will start more often? I'm thinking that if you have like 4 zones with different temperature settings it will request heat separately and not all at the same time. From this perspective it is not better to have only one smart thermostat to control the entire house (normal house with 3 rooms let's say) and balance the system from the regular TRV's than to have smart TRV's in each room? Thanks in advance.
Hi there! It largely depends on your boiler, and how old it is. More modern boilers are less likely to have issues with pressure changes and different heating requests. However, always check with a boiler engineer if you are in doubt.
Hi. I come from a tradition of only turning the heating on for an hour in the morning and maybe a couple in the evening. I'm interested in getting the tado radiator valves but I'm unsure about having the heating on, even at low, constantly. Is it cost effective to do this?
Hi, Thank you for you video's, they are very helpful! I have my smart thermostat connected directly to my heater with the NO+COM lines (not using the extension kit!) but none of the four rooms with radiator thermostats are able to request heat. Do you know why that is?
To answer my own question... I had the radiator thermostats installed first and the smart thermostat last which caused it to create a seperate/additional zone called Heating with just the smart thermostat in it. Assigning the existing radiator thermostats to the Heating group (and renaming the group because re-assigning the group of the smart thermostat was not allowed) seems to improve things. Will have to do a bit more testing...
Forgive me should I get it incorrect, but in my humble opinion, the geo location function is with Tado heating system as a whole, rather than that of the zones. From my understanding is that the heating function in accordance with the location of the users, to avoid wasting heat on empty home and to not to come home to a house thats cold. Therefore, the system would start functioning as a whole to turn on; to heat up the house upon detecting the user’s arrival, which might be unable to achieve by heating up pnly certain zones in the house as it wont be a warm home they are arriving to but one with cold spots.
Hi. My current thermostat in the hall is directly wired to our combi boiler so I initially thought that I could replace this with a Tado thermostat and not need the extension box. Now I am wondering how the radiator thermostat turns on the boiler. Can it do this through the room thermostat or does it need the extension box even if the room thermostat doesn't? Or maybe I have totally misunderstood... We have one room that is significantly colder than the others and so I am going to need to put these thermostats in most of the radiators in the house so that the one cold room can be heated on its own. Thanks
Hi there! Great question. The answer is, no, you don't need the extension kit even if you plan to use Tado radiator controllers for multi-room control. As your 'old' thermostat is a wired one, the Tado thermostat can replace this, and use the existing wiring to control your boiler. If you add radiator controllers, these will use the main Tado thermostat to request heat. Basically, its smart enough to work out how to get your commands to the boiler! So, let's say you have a 'master' heat zone with your main Tado thermostat, and you've got a second zone called -for example- 'living room'. Even if the master zone has reached the temperature you've set, and therefore doesn't need to call for heat, the boiler will still be instructed to run if your living room zone is still not up to temperature. Hope that helps!
Hi What should be the difference in temperature to turn on heating ? For example, if the set temperature is 23 ° C how much must drop the room temperature to thermostat start heating. Thanks.
This is correct. As with any thermostat, if you only have one, then it is the temperature in that single location that determines whether a call for heat will be issued. As such it is perhaps better to go for the Tado wall thermostat if you only plan to purchase one element here. This is especially true if you will be deploying it wirelessly, since you are then free to move the thermostat around until you find an optimal location.
A great series of informative video reviews. I'm still to decide which smart heating system to go for, I am thinking of Tado as we're in a town house and the zonal control seems good. One thing I'd like you to answer if possible. I have read a review that said the valves are quite noisy. Did you notice this at all?
Thanks for the feedback! Yes, there is noticeable noise from the valves when the motor operates. Would I classify it as 'loud'? No, but you'll certainly hear it. In a living room setting some might find it distracting, but to be honest we quickly got used to it. For the bedroom, we rarely hear it, since by the time we get to bed, the room is usually up to temperature, and overnight the valve generally closes and stays that way until the early hours to warm things back up.
Great video. The rad valves have a temperature offset feature which allows you to offset the temperature at the valve to actual room temperature. When I installed my valves, I placed the thermostat in the middle of the room, set the temp on the valves, waited an hour or so, looked at the actual room temp and then offset it, repeat this in every room where the temperature is controlled via the smart valves. The only draw back of this is that it will think your room is colder than it actually is during periods of no heating and only one valve is responsible for controlling the boiler per zone, again you can chose which valve this is in the settings
Nice tips. I installed two thermostats yesterday. Going to see how they work out before investing in the smart TRV's. Impressed so far with the thermostats and software though.

You always need a rad without a TRV to allow the flow and return of water back to the boiler. It will stop pressure build up.

?
For example, if the set temperature is 23 ° C how much must drop the room temperature to thermostat start heating.
Thanks.
Not much, but it depends on a variety of factors. However Tado never seems to let the temperature do much below what has been selected.
If you only have 1 x TRV, if that calls for heat, won't the rest of the radiators in the house get heated as well?
This is correct. As with any thermostat, if you only have one, then it is the temperature in that single location that determines whether a call for heat will be issued.
