Yeah, I used a refurb control module for an older boiler, but any more than that- I’d be looking at full boiler renewal.
I couldn’t see how the diverter valve(s) could be faulty as the boiler was getting a firing demand, but also that the heat from the boiler didn’t appear to be going anywhere.
Hence my advice that the boiler wasn’t actually firing, just ‘trying’ to fire.
New boiler will be more efficient and will see you out probably.
Winter’s coming, how do I know? Because the Nest thermostat is suddenly losing it’s wireless connection to it’s boiler controller!
Nest’s support team simply say ‘oh it’s your WiFi network that’s at fault’ even though Nest uses it’s own network that’s separate from the WiFI
Annoying as it doesn’t turn on the heating when it faults, even though it reconnects when you press the ‘retry connection’ option on the thermostat.
I know it’s not just me as I’m aware of many colleagues that also have the issue.
Well, a quick update. Had the new boiler installed on Thursday (with the Vaillant Protector Kit fitted on the return pipe in the under stairs cupboard). I went with the Hive system in the end, primarily because I didn’t want to be constrained by having to plug in the thermostat. Everything was set up perfectly and I’m very happy with it, and with the extra control it gives me compared to the traditional panel and analogue thermostat I had before.
My plumber then came round on Friday to do the residual work, and we’ve decided that we may as well give the system a Powerflush too as the water was looking dirtier than we were happy with. He’s going to pop some cleaner in tomorrow, and then do the Powerflush with the remaining plumbing works on Thursday. (The company that installed the boiler supposedly flushed everything but whatever they did was of limited value.)
All in all its cost me the IWC I was planning on buying this month, but needs must.
Was a power flush offered before but you refused? Wondering why a flush wasn't agreed on previously.
I always thought a power flush was the default for new rads or boiler?
Just returned to this thread as I was hoping to get a bit of narrowing down to a smart system which initially is only required to operate remotely from iphone.
My lifestyle doesn't warrant smart thermostats everywhere- just the ability to set a timer for HW and CH which can be modified via the phone and remote-switch on/off when I am an hour away from home.
** The reason why traditional systems had thermostat in hall - was that is what was deemed to be the coolest space in the house, so once it was up to temp - it shut the boiler down. It was crude, but worked after a fashion.
That's one problem I haven't had with my Nest, why they are so popular is a mystery to me, the geolocation home/away thing doesn't work, the heating fires up when I'm in my shorts if left to it own devices, support is crap, they just advise you to reset it when you eventually get a response, I just set up a schedule as normal.
