    @Treskelion1959 I've been looking at your online comments toinght. Sorry, volunteer moderators are unable to add 'X' or 'V3+' tags to the thread. Maybe @Emcee can help?

    @tadouser224 So sorry your experience with Tado was unhappy. Our 2024 gas consumption is running at circa 50% compared to the same temperarture in 2018/21.

  • Hello @tadouser224

    Please see the message from my suprior, Jurian, from a few minutes ago.

  • sorry Emcee you sent your email to me (and I cannot see the message).Not sure @tadouser224 has seen the manager’s message.

  • I did receive it thanks. Tado want the units back to investigate them which is good to hear.

    @wateroakley interesting to see your savings. Of course I didn't have tado long enough for it to "learn" but comparing it to two other thermostats (the other smart thermostat I've used and my pre existing Honeywell) tado used the most energy, approximately 10-20% more but it's over a short time so hard to assess properly. Tado would fire in the morning for 1-2hrs constantly and the house would overheat and then would let it cool. My alternatives stop early and allow the hot rads to continue to heat the house which is more comfortable and cheaper. Tado may have learnt this but I didnt get the opportunity to allow it to (although my others didn't need to learn this and did it from the off)

    My savings are harder to gauge since

    a. I bought Tado X for the thread/matter & rechargeable pucks that power the radiator thermostats to span a large, stone-built house more effectively than the Tado V3+ did

    b. I had (hint) double runs of bare copper feed/return 22mm pipes of some 20m each side (so 80m total) on the first floor, never mind the runs of 15mm pipe dropping down to the ground floor reception rooms etc, that we have insulated this winter (my wife thinks the black rubber insulation is ugly, I have suggested that if it is still a distraction by the end of this winter then our local carpenter can frame it in pine).

    I used armacell/armaflex insulation to get the heat where I want it, not the ideas prevalent from 25 years ago (When we had a plumber that suggested a gas boiler with a Totalgaz tank! Not knowing that he got a credit note from Totalgaz for every client). We bought the tanks ground rent in perpetuity so it will sort out the gas burners on our electric Rangemaster for decades (still half-full), our son will enjoy that after we have gone.

    Our current bio-fuel compatible oil boiler (arguably you could make any oil-fired boiler bio-fuel compatible with a new burner) sits in the garage, with a 2500l tank, plumbed in with 2 x 22mm super insulated copper pipe that runs for 15m of which 7m is underground; is cheaper to run, more importantly with the insulation I have reduced the boiler output temperature by 10C (from 70 to 60C, and may yet reduce it further to gauge the penalties incurred heating the rooms since several are in excess of 40 sq m) with similar room heating times (vs Tado V3+ and bare copper), to avoid overheating the spaces not required during the day … although some heat rises through the ceiling to upstairs.

    We also have 2 fires and a range that use compressed wood logs for when we want the ambiance or during a family visit with all rooms heated to augment the boilers efforts if it is particularly cold outside (-10C is rare). We don’t do cold, not at our age.

    We’ll have an indication of our savings (although heat where we want it is more important) by April ´25 but this was slightly skewed by having not one, but 2, Tado X wireless receivers turning our house bathrooms into the tropics at night for a week or so! Normally we use about 1500l of heating oil @ €1,25/l & <2T of compressed logs @ €499/T per annum.

    Oh, NEWSFLASH, nearly forgot why I was interested in posting … third Tado X wireless receiver arrived this afternoon; appears to be working flawlessly to date out of the box (no gentle tap required) … I know, early days but I never had a return with V3+, hopefully that is the end of our issues with Tado X. Now we await the firmware they failed to install within Tado X that was so very useful on Tado V3+ (pre-heat etc).
  • @wateroakley how did you get this graph? I went to the link and it only provides data for an entire postcode and up to 2022 in raw format. Thanks!

    @Treskelion1959 pleased to hear your new receiver is working and you have moved away from the older energy wasting ideas. In this house I was allowed to add pipe insulation where not visible, SWMBO prevailed with boxing in visible pipework.

    @tadouser224 sorry that you have given up with Tado, understandably.
    FYI, it took three months to figure out what worked well for us with Tado. There are many variables. I suspect your description of constant boiler firings and overheating indicates that ‘independent’ mode for TRVs might have been a strategy that others find best for their homes.
    Hope you find a good working solution for your home,

    @tadouser224 The magic of a spreadsheet. I downloaded the published yearly data files and imported the postcode data into an excel spreadsheet. 2023 and 2024 postcode and outcode data is a linear extrapolation. The gas consumption postcode data appears to be mostly complete. Leccy consumption data for every year is problematic for some of the postcodes I looked at. Outcodes can be iffy too.

  • My first Tado wireless receiver locked on a couple of years back, I managed to persuade Tado to replace under warranty and the new unit worked fine until last week when it locked ON again.

    The unit is out of warranty!

    So far taping the unit hasn't cured it, and I can't seem to be able to buy a single wireless receiver unit without buying a starter kit for £150+. I am wondering if this product is not fit for purpose and whether I'd be simply throwing good money after bad.

    This is more than annoying as I have recommended Tado to friends,

    Hi all. If your device is under warranty. Would strongly recommend that you arrange for an under warranty return through the retailer. Often find it easier to buy another one and demand a refund if the retailer drags is feet. Amazon and Screwfix do not hesitate. The return statistics force a review with manufacturers.

    @SteveB1 Hello Steve. Screwfix have the V3+ wireless starter kit for £99. One in stock at our local store.

  • I've installed a V3+ kit this week (Feb 2025) and have had the exact same issue; CH NO remains energised even though the relay can be heard clicking and the status LED turns on/off as expected. [My unit was purchased from Screwfix].
    I'm annoyed to find this thread and that it seems to be a fairly common issue, but also to be honest a little relieved as the reason I installed the TADO was because of a sticking relay in my old programmable [non-TADO] thermostat, so I was initially thinking that I'd mis-diagnosed the problem.
    I've messaged the chat team, so I'll see what recommendations they come back with, but it's a disappointing start to TADO, because as far as other users of the house are concerned I've not fixed the fault ☹️.
    NB. The old programmable stat had been working faultlessly for 18 years, so I can forgive it having a faulty component after that time!

    @HotHouse Hi. This is a forum with end users, all volunteers. One individual, the Admin on this forum, does work for Tado and we escalate through that individual when things are troubling us. Most of the problems that users experience are within their capacity to fix - with our help. In my experience (limited, a little over a year on this forum) one in 17 need actual Tado Support assistance, one in 46 need help with escalating the problem.

    We try to help. A lot of us here have experience with other brands - and arent afraid to suggest that the end user move elsewhere. So do bear with us. We arent in a position to remedy complaints - because we dont work for Tado.

    Appreciate that this forum is burgeoning with people upset, troubled, worried about whether they've made the right decisions. I dont know how many products are sold, however am pretty confident that this forum's problem logs represent a very small percentage of sales. In my daytime job, work in a charity which has multiple sites, all with Tado products - and we've had only 3 instances of product problems with 65 Tado devices, over 13 years, all fixed within a week. Our boilers, our zone valves, our pumps have had far more faults than that.

    The problems reported with wireless receivers delivering faulty triggers for CH or HW are, in my experience - having handled more than 500 enquiries here- not common. When they are logged here, about 3 in 5 are linked either to wiring mismatches, zone valves being stuck, or the setup of digital controls being confused by the boiler - usually the result of its internal control panel not being instructed to let the Tado controls have full control; 1 in 5 are linked to a misunderstanding of how things are set up, one in 5 need Tado support to get into gear and quickly. I have no data on what eventually happens with those. We dont have access to Tado's bug statistics.

    If you want help, please start a new thread, identify your boiler model, the products you have in place, whether you are operating in Relay mode, or one of the digital modes, how long you've had the kit, how quickly the problem appeared and what you've done to check it out.

    We will help. Understand how irritating things can be.
