About this deal

The app doesn’t help as I’ve realised you can’t go back more than 3 months - Drayton you need to fix this. Regardless, Smart radiator valves are designed to provide comfort, convenience and Energy-Saving Features to help you lower your energy bills. Now Bram raised a really good point - about the danger of being tied into paid services (which is why he didn’t go with Tado) or just your system being rendered obsolete by the manufacturer going bust. If you put the room stat in a room with no smart TRV it is controlling the heating in all the rooms without a smart TRV. Correct rad sizing (and now TRVs) mean when the hallway teaches set temp the rest of the house is probably there.

We have 3 bedroom radiators, 1 study, 1 kitchen/diner/, 1 living room, 2 x bathrooms (both towel rads), and 1 in the hallway. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item. The beauty of the room-zoned controls is that you can target the temperature settings if each room precisely based on your regular movements through the house but still easily override when you need too. What I don't understand is the relationship in the app settings between overall temperature (on the "main" wireless stat) compared to the individual temp settings on the radiator smart TRV's.During the recent cold snap I kept the overnight temperature in the lounge higher as it was taking so long to get up to a decent temperature in the day. We also have a newborn premature baby so want to be able to ensure quite specific temperatures in the room the baby is in ie. As a general observation, in the old days with dumb thermostats, you would often have heating on times and off times. My set up has TRVs on every rad in the house, other than the dining room/kitchen which has standard valves. In most cases I would have rooms that are not being used at that particular time set back to 16 degrees - cool enough to save energy but not so cold as to take an age to warm up to comfort levels when you want to use them.

My Pairdeer batteries supplied with the kit worked really well for about a year and then the app notified me as one by one the battery levels got too low. With "dumb" system if you want the house temp raised you just turn the wall stat up a degree or two , the boiler fires up and the rads kick out heat until the stat reaches its set to then switches the boiler off. The fear of battery replacement is what may hold a lot of you back from installing smart radiator valves, and a few of you said in the comments how they wish the valves could be hardwired to circumvent the need for batteries. Now, I can achieve a more dynamic balanced system, and when all rooms have met their targets the boiler heating flow shuts off. Built with multiple sensors for pinpoint accuracy, you'll enjoy seamless room-to-room heating control straight from the app.If I do choose not to put a smart thermostat on all the radiators, would it be worth having a standard TRV on those ones or best with nothing? Smart radiator valves from Wiser simply attach to your radiators like a traditional thermostatic radiator valve (TRV), so it’s easier and affordable to expand your smart heating system. It was hoped it would become industry standard with all the boiler manufacturers subscribing, but sadly they haven’t, and in a bid to tie us into their system with extended warranties and the like if you adopt their controls they’ve developed their own versions of it e. And Tado, Type 17 has Netatmo along with the Netatmo weather station outside - which is more accurate than relying on regional weather info.

You’ll need a connecting device to go into your modem so your mobile phone can communicate with the smart valves. The same with the bedroom, however it warms up ever so slightly, like as if it was the old Danfoss TRV set to 1 or 2 out of 5. As Dan at Drayton pointed out to me, even Opentherm has its disadvantages as by operating the boiler at lower power it’s going to take longer to get up to temp albeit when it’s there, it will maintain a much more consistent temperature . Any zone with just dumb TRV's or no TRV's is at the mercy of the smart zones to start/stop the boiler. Smart control systems can be adjusted from an app or a central console and bring many layers of sophistication to the system that will reduce your gas bill and carbon footprint further without necessarily reducing your comfort, as we will explore.However, if you already have a smart thermostat, then you probably already have one of these installed. In my experience with a whole home setup they are not all that accurate, and can vary by a few degrees in terms of actual room temp (compared to when using a thermometer and the wiser wall stat). Jon Giles got me excited by pointing out there’s a Nefit Opentherm adaptor he was hoping to be able to fit to his Worcester Bosch boiler, but sadly my 10+ year old Greenstar Camray isn’t compatible with Opentherm - and even if it was, I’d need to change my plumbing and fit an integral diverter valve kit to adapt my Splan system to the EMS/Opentherm system. Ref the comments in this post about utilising existing Danfoss TRV bodies, most of my system uses old Danfoss RA's which I have converted to smart using the supplied adapters. so if by setting a TRV to 20 degrees and a thermostat in a non-TRV area to 14 degrees that area may get to over 14 degrees before the TRV gets to 20I'm not sure how I "tell" the hub that the thermostat exists.
