I’m writing this on behalf of my 85+ year old mother. Apologies for the long post but it does explain pretty much perfectly the issue.
Shes with OVO and has been for many years, this year her very old manual thermostat started playing up and heating was coming on in the middle of summer and was a nightmare.
I saw the Tado V3+ (Wireless Thermostat, Internet bridge and wireless receiver) deal OVO were offering earlier in the year and she bought it. Eventually an electrician installed this around June, it's been working perfectly since then with her Baxi EcoBlue boiler.
As she is on approaching 90 and is quite frail, shes like to have the heat on so its been working from around October/November time, she likes it at an indicated 23degs. I dont think it is quite that high but feels better than the 14degs on her old thermostat!!
We have a schedule setup so from 10pm-7am daily she has it set at 14 degs C, 7am-10pm 23degsC.
Her bungalow has exceptional insulation and over night, even when its cold outside it rarely drops below 18-19 degs C, During Oct/Nov the heating would come on at 7am and keep the temps pretty consistent at 23 degs C. Until a few weeks ago.
Often it comes on at 7am then just stops, you can see on the chart displayed on the app where it starts then heat just starts dropping, it drops slowly due to the insulation.
I carried out some tests whilst up there as I feared it might be the wireless causing issues, using the app triggers the receiver but sometimes its just doesnt. The tests on the receiver only for the most part worked well, the boiler typically came on after 30s-1min.. But the test buttons only turn on the system for a few mins then turns off by design I presume.
By upping the temp on the app and sometimes hitting the hot water button on/off the system springs to life, others it doesnt. She could have heating all day, other times it doesnt work and requires lots of intervention to get it working. Its starting to get very very annoying and frankly its close to getting ripped out, we cant have my mum using this system as its too unreliable and at this time of year its not good at all.
.
The following chart shows it working well on the 21/12 and rubbish with lots of cut outs on the 22nd, when it comes on it would have been manual intervention (Perhaps lots of it) .
Frankly were at our wits end with this system (I live 150miles away so its not easy to just pop in), is it worth persevering, is support offered through OVO or Tado?, I’m tempted to send it all back to OVO and putting something old school back in that works ?
As a backup I’ve bought her some convection heaters, but the down side to that is the heating is unlikely to kick in as the thermostat is in the lounge and with that heater is nice and toasty, but now trying to get to the bottom of the issues is even harder. Its also getting expensive.
This isnt great for a vulnerable person at this time of year.
Help please
