I have just fitted the system. It was easy to install, and it is performing well with 9 smart TRVs. Only issue is the battery life on the TRVs. I got excellent support from the Wiser team. Recommended.

great review - thanks. I invested in this system around 4-5 months ago and whilst it doesn't have the "brand kudos" that nest/tado has, it's a system that works well when you've figured out how to schedule each thermostat/room. It's worth mentioning that you can completely remove the room thermostat from the system (which I have done). So the system purely works off the TRV's, and I find that the TRV's cope very well in regulating the temperature.

I have the exact same boiler as you in a previous house. I installed a Honeywell Evohome and not had half the issues you’ve had. In my current house, I have Evohome again, and this time I have UFH and use Opentherm too which as you’re aware the Potterton doesn’t support. My current boiler Ideal Vogue Gen 2 S15 and the Evohome I can lower the output temp to maximise condensing whilst maintaining a temperature of 65°C for HW. You’re probably aware ASHPs run on very low temps, and so I’ve managed to lower my heating output temp to 35°C output which coupled with UFH ensures comfort with maximised condensing efficiency. This will put me in good stead for when I’m ready for ASHP.

Good honest review! I wish Nest would do TRVs to add in. The home/away feature is really handy... not so much now people are working from home more.

Fab review coming up to around 8/9 months with mine, still doing some fine tuning but overall happy. I was advised that Geofencing was in a 3-6 month roadmap which we are now about 4 months in on. Hope it comes soon.

thanks for he honest opion

Had the Wiser system for 6 months now. Easy to setup, very reliable with no disconnections from the Hub. As you said, these systems are more a luxury than a money saver as purchase costs are very high. My wife and I live in a detached 4 bed house. For rooms we rarely use I have kept the manual TRV's, keep these rooms doors shut night times and installed the smart TRV's in the kitchen/diner and lounge. Our house in now very comfortable in our living areas. If we find the lounge a bit chilly the App is brill for boasting the heating. One day I may invest in TRV's in all rooms so I have complete zonal heating control.

3 years in and I find it pretty easy to use both (with our system boiler) at the thermostat and alos the app don't bother with smart TRVs. However its connectivity has been patchy since I moved to a Vodafone router from the previous BT one.

Thanks for the review. Think the Drayton Wiser system is very competitively priced against other similar solutions though? Nest is just one smart thermostat. If you have the Drayton Wiser smart rad valves on 11 radiators then you have 11 smart thermostats + the other smart thermostat box. 👍😊 I've never had a smart thermostat product before but I'm getting my Dryton Wiser system installed today so fingers crossed it will be useful. 🤞

Have you seen Home Assistant? It looks like it has a good Wiser integration and means you don't need different apps for every different brand. Everything is in one place

One thing to note on cost comparison you mentioned a new arrival 6 months ago speaking from experience when that happens you generally spend a lot more time home so comparing the usage to nest is very hard other than that great review

Nice comparison, but sound a bit difficult here, either try a close mic or a room with less hard finishes for recording! Are you finding the trv temps fairly accurate given they are right near the rads themselves? Or have you added more roomstats?

Great review - i'm moving to a property with an LPG system (which costs almost 3 x times the price of mains gas), and i got the kit 1 with 2 x valves for £110 plus i have bought another 7 for a total of £280 plus 2 x smart plugs for another £80 - so all in for less than £500, so i think will be pretty cost effective over a much shorter timeframe than yours - coming from a 1980's TRV-less system, this should make a massive difference to heating costs and comfort levels!

Good review, I've watched both of your videos I understand your trying to give as much information as possible but sometimes less is more. If nest did TRV they would be on the higher end of the market but would be less reliable considering the amount of heat links that are being replaced because they stop working. One other point your boiler the powermax, was not the best boiler when it came out and definitely will need replacing in the future. Due to the fact it's 16-17 year old

Also worth noting is that if the internet fails this system will continue to work when your at home. When out of the house it can be controlled from anywhere in the world. If all rads have a smart valve you don’t actually need the central controller at all

Nest might look nice, but what does it do? It doesn't have any radiator valves - it's just a single (overpriced) whole-house room thermostat (right?)

Did you do a comparison on KwH or £? Seen a comment where you said the bill cost was near identical but rates have gone up loads. Also worth noting that whether the system is cheaper than Nest will depend on how many radiators you convert.

Geofencing in their own app is something they are working on (I left a review saying that lack of coherent geofencing was a big minus point and they replied saying it was one of main points they were working on)

It would have been useful to have more detail about the issues you had with learning the app, and may show using it, since that is the main way to interact with the system

I have a Nest and very surprised that they have not yet got something like this as the nest with smart TRV's would make a perfect system - even the ability to pair extra room stats would help but nest insist on the One stat for the whole house route. I am now dumping nest and have ordered this - hopefully it will be a worthwhile upgrade - I agree with you ref the look of it though V cheap looking and you have to poke the stat to get the display to show. The ability to wire it and have it display all the time would help.

I don't get how you haven't saved over using a Nest. A properly configured multi-zone system heating only the required rooms at the required times should outdo a single zone thermostat hands down. Are you just running it like it was a single zone system? If so, that totally misses the point of it.

You could have used any WiFi extender rather than their smart plug. Get yourself a mesh system if you've WiFi issues around your home.

I wish you all luck with this. I've just installed 10 of them using the Opentherm connection to my new Baxi 800 combi.....and I'm probaly going top have to remove them. The issue is with the two devices that DON'T have TRVs on them: namely the rad in the hall (where my Nest was originally) and a heated towel rail in the bathroom (that don't have TRVs anyway). When the system calls for heat for one or two rads, these other two make a heck of a noise and get super hot. The noise is apparently water under pressure, so it's like running water. I think it's more like the sound you get when you switch your kettle on. According to my plumber it's because these smart systems don't take into consideration the fact that the boiler cannot vary it's pump speed (I have a new Baxi 800 combni fitted last November). In a conventional set up you would generally have most rads open, so most of the volume in the sytem is available and the pump speed copes with that. In these new setups only one or two rads may be open so consequently the volume in the system is much lower, but the pump is at the same spped and thus th rushing water noise.....or something like that. I'm no expert as you can tell! Anyhoo, apart from the noise the hall and bathroom end up at aorund 24 degres when the highest zone demand is 20! Admittedly the rad affected is an older single panel so I could change it and put a TRV on it, but apart from the extra expense I thought you still needed to have at least one rad without a TRV for overrun and I'm not sure the towel rail can serve that purpose. Probably time to cut my losses and go back to the traditional set up.

I would say that the Wiser could make your running costs significantly lower than Nest depending on personal circumstances……a lot of people working from home these days…..I don’t, but if I did and I was in my at home office all day I could heat that one room independently all day with Wiser…..if I’m at home and crank up the Nest it’s going to heat 11 rads rather than one so the boiler is going to burn significantly more gas during a working day, Wiser wins hands down !
