Heating/CH NO terminal is constantly "on"

@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.0 -
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)0 -
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).0 -
@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,1 -
@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.
