It can be done but you need accompanying SRVs in each room alongside the wireless thermostats; slightly expensive option . . .
You can control multiple rooms independently with a Tado wireless room stat and Tado trv.
Since January 2022 we have spent £750 on 14 Tado devices. Looking back at the monthly gas usage for 2018-21, the Tado spend has helped us to significantly reduce our home energy use for heating and HW. For the last 12 months the saving on bills is £1,300, that's over £100 a month. ROI of 8 months at present UK energy prices is a pretty good return.
For energy ROI comparisons ... The home-office IT refresh with recycled devices was 1.5 years. Replacing the very inefficient 1970's warm air heating with a wet system and more insulation was 7 years. On a different measure of 2018-21 to 2023 home energy efficiency, annual CO2e, using Tado controls has reduced our footprint by circa 2600 kg.
Blimey! WaterOakley's monthly SAVING is around twice the actual COST of my monthly heating bill during cold months! I mention this solely to show the huge differences we will have across the board here and I tend to side more with GrayDav's point that it is likely that the cost of convenience etc weighs against the benefit of reduced energy consumption for many users?
I've tracked my energy usage month by month since start of 2020. I installed Tado start of 2022 so have some good data. I have quite a large system and it cost £887.46. I use auto-assist (and am ignoring that cost in these calls) as well as using IFTTT to use individual person/room geofencing for my home office and the kids bedrooms. I am seeing average annual kWh saving of 9955, at 7.5p a unit that's £746, so covered my costs in just over a year.
I've got that by only heating rooms at specific times when I need them and also by being careful not to heat hot water when I don't need it either.
So that's real money kept in my pocket, and commensurate reduction in carbon so great, but I have some other benefits, mostly around comfort. Three examples:
I used to have one room that is colder than others. I can now heat that room individually so it is always right.
I don't come home to a cold house when away for a while.
I can control heating from the sofa.
Don't get me wrong, Tado could be a lot better, but is is considerably better than a dumb thermostat if you persevere and if you are a little bit tech.
I hear and agree with your comments.......I have been a tado user for just over 3 years, and have tried just about every conceivable combination of setups ........I think that I have finally got a system that works very well (for me).......I have replaced all my tado SRT's with old "dumb" TRV's........I have 1 Wireless Thermostat and 1 Wireless Temperature Sensor to control the "firing" of my boiler. Most of my TRV's are set on 2......and my boiler Flow temperature is set to 60°C. I am utilising the "Low & Slow" method of heating my home. When the weather gets properly cold, I can easily adjust the boiler flow temperature and also adjust the relevant TRV's. I am naturally always trying to be as economical as possible in our 3 bedroom detached 70's house.......however I have come to realise that there is no 1 specific setup that works for everyone, cos our households are all unique to ourselves.....and @thefern if your system works for you and you are happy with it.....then it's "right". 👍
@GrayDav4276 am I the outlier? Probably. Definitely trying to cut down on the ££ energy spend after ‘retiring’ from paid work. The 2022/23 heating savings we have implemented are a) changing ‘whole-house’ heating with dumb trvs to timed CH of rooms and HW. B) one or two days a week, leave home very early, turn everything off. near home late, turn back on. Without boiling the ocean, the data reports a circa 50% saving on HW energy by timing carefully instead of 24x7. In there, a regular 20% saving for every summer day out, from a short HW schedule of x2 a day instead of x3. The downside is forgetting to change the HW timer and an occasional cold shower, brrr.
