Wiser Smart Heating TRV Radiator Valve WV704R0A0902 White - Single Unit

Upgraded my old setup 2.5 years ago. I was looking for a while to change old TVRs for a smart system in order to be able to maintain a stable temperature in the baby room. Turned to be so good that I later bought 3 more smart radiator thermostats and now have one in living, kitchen and all 3 bedrooms. Good stuff: 1. Easy setup. The Smart TRVs themselves also super easy - screw on, for those who never changed one before, don't worry, no water leaks involved, you just screw off the old one (valve stays closed) and screw the Drayton one instead. I did mines even with a bare hand. You might want to add a half turn maybe with a corresponding key if you have it, but make sure to add something soft in it to not scratch the metal bezel. 2. Per room temp control. This brings up great flexibility. You can set up individual temperature for each room. This is exactly what I do, a bit higher for living room and kitchen and cooler for bedrooms. - So you have an option to maintain 24/7 same constant, comfortable to you temperature in any room, without overheating or overcooling it. - Otherwise you can set up a convenient schedule instead, to have particular temperature at certain time, which is also convenient - for example waking up in a warmer house and then switching it of while you're at work, but heating the house back while you're on the way home so that you get back in a cosy place. All this functionality is truly amazing and convenient, and really improves comfort. 3. Great value for money. If you're going to check other brands and try to get/build a similar kit (tado, nest, bosch, etc) - you will pay a lot more. Also, for example with google nest you don't have it's native TRVs so you get a smart thermostat, but one only, basically for the whole home. Also, money wise I am pretty sure in 2.5 years that I am saving money, as I'm seeing similar bills but after energy prices went up. All this while having constant temperature in every room 24/7 without any worry or plan, or need to heat & wait, etc. Basically set and forget. 4. Simple yet functional. Here to mention both TRVs and the app. Smart TRVs - Two AA batteries in and you're good to go.You have a plastic wheel / physical control with either + or - , which will send you're current temperature 2 degrees up or down. - Physical control lock. A very convenient thing for small kids. Mine were unlocked by default and I could not understand while heating was on several times and overheating a particular room - when I later spotted my little one just playing around with them :) so a simple "lock" from the app sorts this out. - Open window detection - to close the valve if a draft is detected. In fairness precision of this functionality is questionable. At least I did not feel it's reliable. Maybe if the temperature drops really fast, like a open window when outside is much colder - then maybe yes. Otherwise don't rely on it to save you :) APP I do like the app. It does not break any records or win app "grammys" but it's simple enough with decent functionality. - Easy add or reduce temperature to any rooms where you have a smart thermostat - Easy boost to any room, 30 mins, 1,2 or 3 hours + off. - Setting tailored schedules for both temperature and time that can vary during the day. Also, saving this schedules and being able to toggle on/off the usage of the schedule can also be very convenient sometimes. - Eco and comfort mode. With eco the app is trying to maximize efficiency of your system by learning your usage patterns, while in comfort the idea is simple - if you want for example 20 degrees when you wake up, the system checks the inside & outside temperature and makes sure it starts heating in advance so that 20 degrees are achieved when you wake up, and not just the heating starts at that time. - You get informative energy efficiency graphs and how the outside temperature correlates with the amount of time the heating was on - on a certain day - THINGS TO NOTE: 1. TRVs battery life. I've noticed that with constant temperature set 24/7 (no schedules) - the smart radiator thermostats go on and off much more often in order to maintain the set temperature. I don't know if it will reduce life of the thermostat itself, but it defo reduces life of 2 AA batteries :) Checking the app two batteries make it through the winter/cold season here in Ireland - but defo would need a change after that. 2. Connectivity is not perfect. My hub is at ground floor, so the ones at first floor show 2 out of 3 signal and the attic shows 1 out of 3 bars. Same time, maybe slightly delayed but looks like all TRV are receiving the signals/commands from the hub as they switch on/on and do the job to maintain the set temperature. Still, keep in mind that depending on your house size this might be something to keep in mind. I think I've seen some range extenders from Drayton to cover up in case you need it. To wrap up: Overall, the amount of advantages for the price you pay makes it an amazing investment in your home. The comfort and convenience + long term saving you money & paying back for itself. Not many purchases give you this much value really. Not perfect but something that I've extensively tested and can responsibly recommend. Stay warm and cosy friends! Cheers!

Great product,well packaged and really easy to install and add to my Wiser smart heating system myself without the need for paying tor my heating engineer to install it. Paired easily with my wiser hub and has enabled me to control the upstairs as a separate zone to the downstairs just by replacing a normal TRV with this smart one. Took less than 5 min following the easy fitting and calibration instructions. Setting up a schedule is really easy too. I intend now to buy additional smart trv's which will give me the ability to control other individual rooms. BrilliantCost effective

We have a house with solid walls. Some rooms are warm and stay warm, others go cold really quickly. We had a Worcester 34cdi with old drayton RF controller built in, and at night the bedrooms used to drop way below the setpoint of the wall thermostat - not great for kids bedrooms - especially when mold started for form in the colder rooms, so had been looking at Smart control systems. (Insulation is a few £k so trying this option first) This kit came on a treasure truck offer few months ago so bought it, plus 3 additional radiator valves. Had to arrange an electrician to install the wall plate and the hub to the boiler... £60ish and less than an hours work. The rest is done via the app on your phone. Positives: -Responsive accurate control of the system -Able to have a temperature zone everywhere you have a sensor -You can create a schedule of times/temperatures and assign multiple rooms to that schedule, or you can have a schedule per room (as we do as our use of each room fluctuates). - Radiator valves (TRVs) *very* easy to install and setup (just observe the battery polarity markings!... as the typical "springs" arent the same as other appliances... I spent 30 mins trying to figure out why none of my valves was powering on...to see that the batteries were in wrong!). TRV up/down can trigger a 2c boost for 1hr for that zone. - If you have a TRV and wall control in a single zone then the wall control automatically overrides the heating-demand on the TRV itself. - TRVs are simple in that there is no pull out display like the honeywells. Just boost up/down twists to change current setpoint. - Not too loud... slight whir for split second when temps adjusting... eg if too cold you hear the valve open, then the heating comes on. If the boiler is on and they dont want heat... then they whir shut. - Make sure your valve-body pins are free... get pair of pliers and shift up down a few times with a little wd40 so the motors dont have quite as much work to do. - We have solid walls, but didnt need the range extender. Furthermost valve needed to be connected to hub a bit closer, but always responds to control now connected. - android app is intuitive and easy to make changes in; there are now also battery status bars for each device and alerts when getting low. Plenty of insights of how your house behaves thermally, compared with say the outside temperature and what rooms heat when. (Mine is saying to install a TRV in our lounge as we are overheating it constantly as its an "always on" radiator - which had suspected). - comfort mode works out over time what your room takes to heat vs outside weather and turns on the heating before scheduled time so it reaches the set point when youve told it to. Works pretty well IMO. - there is a "eco" mode but not tried it out. Apparently its turned our heating down quite a few times when not needed... time will tell if reduces bills, but we bought it more for comfort so that we didnt have to wake up in middle of night to turn heating up for the kids. - hub range pretty decent. Our hub is in our outhouse round back of house and we still get 2/5 signal upstairs at front of house; the rad valves seem to maintain decent connection just the app sometimes struggles. - each of the smart TRVs can be "locked" so can only be changed via the app... useful if you have little hands that like to fiddle with things that whirr and flash Negatives: ipad app: - layout... doesnt landscape when you turn the screen - doesnt have the "settings" options... for that I have to use my android phone... so wouldnt have been able to setup using our ipad. Also doesn't work with older ipads (we have a mini it wont install on, which might have been useful to just put on a wall in the hallway) Android app: 1. latest update... if low signal to the hub it sits waiting to connect to the hub before you can change any settings... previously you could go in, review and only when you came to change something would it complain about hub connection... now... it just blocks everything. Loathe to buy the range extender given its 1 corner of the house that has the problem and we are moving our boiler soon. 2. Initial setup - I couldnt create an account without the app being connected to my hub... so as such I couldnt do that side of things before my hub was actually installed All access is via the "app"... that is you have to have a phone/tablet to control the system with any granularity; there is no way to login online and make changes, even though you can control the system via the app when away from home. Only things missing IMO from the infrastructure are: - TRVs dont have a temp display on them (see honeywell). - a more advanced display control unit to upgrade to (see honeywell) - underfloor heating manifold (again...Honeywell) (we are planning this on our extension next year, so if not available will have to change systems, but for the price "right now" this is a no-brainer) - ability to login via a web-page and do all the same things the app can do So far so good. Id **thoroughly** recommend and would buy again. Update: replaced my lounge radiator lockshield with a wiser trv (for some reason this was our pass-thru, so moved them to the bathroom rad instead). Head registered then lights would randomly start flashing. +/- worked in opposite direction and then it disconnected and lights were flashing at random. Clearly a dud. Raised with Amazon who sent out next day replacement (which works perfectly) and now our lounge wont be epicly overheating whenever any other room demands heat. If you have a smart meter you can also integrate with that, but my supplier (BG Evolve) doesnt do smart meters - not sure how it looks on the app. I like the insights view shows you when heating was turned on or off during setpoint cycles. It shows external temp (from weather forecast) and internal temp in the room vs setpoint so you can see how outside temp influences internal temp and then when the system triggers. I guess it means you can look and see if its triggering when you arent using that room and adjust the schedule for that room - which I had done up front as our activity is fairly predictable 3 year (?) review: Still love the system... so much so... we hardly notice it tbh We have gone through a few sets of batteries so switched to 2800mah AA rechargeables - and the TRVs struggle a bit with power-levels as the voltage is ever so slightly lower than a non-rechargeable. I have had to disable power-low alerts as they were firing constantly. Drayton could update their TRV firmware to be able to self-calibrate for using rechargeable batteries. Changing batteries... if the signal is weak... then have to identify the TRV the valve off-radiator closer to the main control unit and then fit it back...network signal seems to be ok then. Maybe a suggestion for drayton: these are IoT devices... so why not allow use of a wifi network as a secondary connection from hub to devices?

I researched a lot of products, and although this one looked really good, I couldn't help but wonder why the TRV heads were £40 rather than others which were around £60. I thought they may be inferior. I need not worry. They are brilliant. I've worked in IT for 30 years, so setup was a doddle. Even installation was one screw and just swap my old timer for the Wiser hub. It fitted on the old backplate so no wiring required. I just turned my old thermostat to max so it just kept the thermostat permanently switched on, giving control to the new Wiser kit. Once installed, I set up the schedules for each room individually. On an old system, you set all radiators to switch off at a certain temperature, but if you have all radiators set to 20 degrees, for example, then if the temperature is 18 degrees, then obviously all radiators will switch on. With the Wiser Smart Heating system, you then go one step further by saying (for example). I want the bedroom and bathroom to come on between 6 and 8.30 at 20 degrees with all other radiators OFF. I want the office radiator to come on at 8am at 21 degrees, and the bedroom and bathroom to go off at 8.30. I want the office then to turn off at 5pm, but I want the lounge and hallway to come on at 4pm till 11pm. And I want the bedroom to come back on a 9pm. Stuff like that. It basically means that I am running 1 or 2 radiators all day (or until they reach the required temperature), whereas before I would have been running 10 all day. I can only assume that with the horrendous price increases in the UK for gas, this has made a huge difference. We have a reasonable sized 4 bedroom detached house, and after April, our monthly gas and electricity bill will rise from £100 per month to £130 per month. This is the lowest of anyone we know. We are on standard tariff as our supplier went bust, so we had to change supplier recently to a new one, and they had no fixed price deals going, so we ended up on standard which is one of the highest, and we have smart meters, so they know exactly how much we use. People we know in smaller houses than us are paying far more than us (in some cases more than double). I can only assume it is the Wiser system making the difference. But it makes sense, as having 2 radiators on instead of 10 is a big difference. The only negative. The app needs some more thought and some work. It's great at setting basic schedules, but they need to listen to customers more. I think it must have been designed by a developer. When I first had it, I gave them some feedback saying it is really good, but you should be able to have overrides to the regular schedule for specific dates (like on Microsoft calendars). E.g Aunt Ethel is coming to stay next Thursday for 2 nights, so during that period keep the spare room at 21 degrees. The only way I can see is to wait until the day of arrival and then amend the regular schedule to suit or set it a constant temperature and tell it to ignore the schedule. But with both of these options, you have to remember to undo it afterwards. I heard nothing back. Overall though, this is an exceptional system, far better than I could ever have hoped for, which I believe is saving me a lot of money, and probably paid for itself a long time ago. It just needs (like all apps) ongoing customer engagement and development. I would be happy to perform this role for free as I have been heavily involved in mobile app development and I love this product, and I would love to be able to help others save money with the fuel price crisis in the UK.

I have just had Gas central heating installed and I was looking to make the Gas Central heating smart. It took weeks of looking into it and many different products...In the end I went with Drayton Wiser because of the reviews and the supposed flawless ability to control every radiator individually. Well I am pleased to say i am glad I went with this product.. Friends of mine have different systems and they do not have the control that i have...The plumber fitting the central heating system insisting this system will not pull water from the boiler directly it will have to go to the main thermostat first...I said to him we will agree to disagree...The next day he told me that his fellow tradesmaen had stated the main thermostat will control the radiators..I again said we will agree to disagree...Well it was me that was correct and left the gas engineer Gob smacked. I have eight radiators and the radiator in the hall is the open all the time radiator as a fail safe so if you are pulling water to any other radiator you will get this radiator on as well so fit that one without any smart TRV into the hallway as this is usually the coldest room and the wall thermostat will control that one only....The other seven radiators all have Drayton Smart TRV's and I have total control....I give you an example...If i want just the kitchen to heat up I can...The smart phone app is brilliant showing a list of all my rooms with the radiators...lets say i changed the temperature for the kitchen radiator from say 18C to 24C and the app will show a flame telling you the radiator is powering up and calling water and around ten to thirty seconds you hear the smart TRV on the selected radiator make a little noise as it opens the valve then the boiler fires up and about ten seconds later the radiator starts to get hot.All the other smart controlled radiators are still off because they are not requiring heat. You can then set the scheduling for any time for each radiator to come on and off and at what temperature....complete control...Example the kitchen may be set to 21C and the Lounge at 23C while the bedrooms are off...that is until later if you so wish... This is total control and I cannot believe how good it is. I have the room where my cats are on most of the time but the rest of the system is just set to frost protection until i need them on and they fire up on the time I have requested....Lets say the scheduling is due in an hour but its cold instead of changing the scheduling just set a thirty minute one hour or three hour boost to whatever radiator you want. Its total control and it is already saving me money....Two other settings of interest...a COMFORT setting brings whichever radiator you want on earlier than the scheduled time so the comfort temperature is there when you want it...I don't use this because I think it would use more gas..I do use however the ECO mode, well this setting monitors the weather outside and how quickly your house heats up and cools down and assists in saving you money......This is an excellent product easy to install and operate, eventually your schedule will run the house without you having to do anything.....My cats love it...Highly recommended

The Wiser system has all the potential attributes of a good system - an ever improving app, the ability to individually control radiators and a swift installation process. However it it is fundamentally let down by inconsistent and inaccurate temperature readings. Whilst the inaccurate temperature readings could be accepted the inaccurate readings each day make it impossible to work with. For example I installed a radiator thermostat in a child's bedroom and programmed it to not fall below 16 degrees during the night. Went in the next morning and the room was 12 degrees despite the app saying the room was 18 (meaning the radiator never came on). The living room I have set to 20 degrees but other thermometers only state 17. To compensate I tried setting the desired temperature to 23 degrees. This works some days but not others. I contacted support about this who advised to do a factory reset on the thermostats and I also tried swapping them round different rooms and radiators but none of this has worked. I've also installed the signal booster plug to no great effect. Of the 6 rooms I have used them in 3 are just manageable using Wiser heat radiator thermostats (with the caveat that I'm had to set the temperatures higher on the app to get to the lower real temperature), one other I have had to add a room thermostat in there also (the room thermostat becomes the master in these scenarios and overrides the temperature reading from the rad thermostat), the living room I have to adjust manually each day to get the desired 20 degrees and the final room I've reverted back to a TRV. Whilst it's possible that I have saved a small amount of money turning off individual radiators the hassle of constantly reconfiguring the temperature schedules and factory resetting the thermostats to get them to report a sensible temperatures means I most certainly would not recommend this system.

I've had two control systems from the boiler manufacturer, neither were cheap and both failed within two years. Won't mention the manufacturer but they are one of the higher end domestic boiler manufacturer. The boiler is a combi but the wiser system would easily integrate with a heat only boiler system ( one with a hot water cylinder). The system was very easy to install, the thermostatic radiator units simply unscrew and the wiser radiator unit screws straight on. I was replacing my old honeywell Thermostatic radiator controls. The kit comes with and adaptor which will allow the unit to fit most makes of radiator TRV's without the need to drain the system. I found the unit very easy to set up and pair the TRV to the system. The only criticism is the system isn't opentherm compatible so its simply a on/off but the way the system performs is very much like a opentherm system. With standard thermostatic radiator valves these simply shut the water off to the radiator, this doesn't interface with the boiler, only a room thermostat and time lock can turn the boiler on and off. With this system it is possible to turn the boiler on and off when any of the TRVs are calling for heat which is fantastic. For instance if your working from home and only want to heat say the living room and kitchen this system will allow these rooms to be controlled simply and efficiently without trying to heat the whole house, as long as each radiator has a wiser unit fitted. Instead of heating the whole house you can now control each room however and whenever you wish. We have noticed a drop in the gas bill which is really why this system was fitted an long with reducing the CO2 footprint. The house is small but WiFi is always an issue, ro the point the computer upstairs has trouble with WiFi so its hard wired, to date I've not had any issues with connectivity at all, this isn't to say if you have a larger property or a poorly placed router a range extender maybe needed. We have had this system. I have had to change the batteries in one or two units in that time, to be fair these are the ones that come with the unit so I don't expect them to be the best, changing the batteries and reconnecting the TRV back to the system only takes a few minutes and probably will take less time now I know the procedure to rediscover the TRV. Lots of data can be accessed in the app, so the tech minded gadget lover can see what the system has been upto. Initial cost is a bit high but compared to the benefits this system provides is comparable to fitting a control system to a existing system, without the need to run cables to time clocks, room thermostats etc. All in all I can't recommend this system highly enough.

Had been considering a smart set up for a while and looked at Nest / Hive etc - saw this and thought it was reasonably priced so bought the Start up kit with 2 TRVs. Very easy to install, removed old programmer with 2 screws and replaced it with Wiser hub (2 minutes). Downloaded app and created account and replaced 2 TRVs and put the room stat on the wall. Works so effectively, I went on to order more TRVs and have control of the every room in a busy house with lots of different demands for each room at different times. So now I can heat each room as and when needed without heating the whole house. Away mode does what it's meant to when we're away on our travels. Never had any issues with hub disconnecting or rooms disappearing off the app like some reviewers. Never had any issues with connectivity or needing a range extender - and the house is over 3 floors. Not had to speak to customer support as everything was clear in the instructions and works. Have had the system for a couple of months without any issues at all. Just make sure 'pin valves' in the body of the TRV are not seized so that they can operate smoothly. The app interface is a little 'clunky' could do with a design refresh to help make scheduling a little easier and user friendly, but a small niggle in the scheme of things. Would highly recommend the product, the heat reports it provides via the app are interesting, and I can state that my bills are reduced as a result of installation, but it is the convenience of it that makes it worth having rather than the savings - at least for our house anyway - my wife has a quick natter with Alexa and the room she wants heating gets toasty, I use the app - each to their own but we like it.
