Heating Not Coming On When Stat Is Turned Up - Baxi duo-tec 28 he

[robtherevelator1969]

This fault exists with the newer wall thermostat and it happened with the older dodgy one. When the thermostat clicks on sometimes the boiler does not fire up for the heating. Its an intermittent fault and i have the boiler set to on at all times. When the heating does not start i need to go to the boiler, switch it to timer, it fires right away, then back to ON and it stays on, usually it works for the rest of the day without issue.

I know the wall thermostat is ok because its a new honeywell digital one. Does this look like its boiler related and will i need to get an engineer to look at it, im just thinking if its an intermittent fault it might be hard to troubleshoot. Does anyone know what the problem might be?

My first thought would be dodgy programmer on the boiler.

Thanks for your reply. Is it possible to check if this is the problem or it a case of replace it and hope it solves the problem?

Is this something that can be done at diy level or is best left for an engineer?

Lots of diy folks are quite happy using a multimeter to find these sort of faults. It just depends on your previous experience.
As you normally have it set to be on permanently you could try setting the programmer up so that the timer is set to be on for the majority of the day and night. Then see if having the heating switched to timer makes it behave.

Thanks mate. I have a cheap needle multi meter, i am capable of using it if im told what i need to check. I put it on timer mode at weekends when im working and so far i think it has been fine on timer mode. I will set the timer to be on most of the day and see how it behaves.

I dont know why i have absolutely no bell ringing experience.

If you keep it on constant, just use the timer and nullify the 'off period', as suggested. Sometimes you can adapt and overcome without spending... but the law of diminishing returns can still prevail, eventually

I have been using forums for about 16 years now and im well aware a username change does not make you untraceable and all your old posts are still linked to your profile. I did it for 2 reasons, to see if you would notice and you did plus i no longer like that old username, so i found this was a fun time to change.

If i wanted to be totally incognito i would delete my account, reregister and so on. I know all my old quotes are still under my old username, yawn but thanks for pointing it out to me and thanks for being so predicable lol
