Please don't laugh, but I'm getting desperate...!

Hi guys.

Before I start, please don't shoot me! I've had 2 guys said they couldn't help and 1 who refused come out!

I have an Ideal Response 80, at least 8 years old.... I know, I know....
Anyway, after pressure loss/build up I've retrofitted a replacement ex vessel.
All's been refilled/bled etc, but now the CH burner keeps cutting out, but pcb doesn't lock out.
DHW is ok and there is constant call for heat, but the CH burner comes on/off every few seconds and CH temp wont increase.
I've checked fan, pump and for air locks and all seems fine. As HW works I'm guessing it's a bit more sinister?

I'm gonna try CH temp sensor tomorrow, but has anyone got any other ideas?

Really need to try and sort this 'cos I just can't afford a new boiler.
Is there anyway of knowing if it's the HEX for sure? I'm prepared to try all alternatives.

Thanks, Sean

Have you got a hammer?

 

[compo69]

Yep - tried that one too!

Thanks for the input....

have you opened the aav on the top of the boiler? try overpressureing the boiler as sometimes this hepl clear an air lock. failing that, try bg for a fixed price repair. we MAY be able to sort this.

i dont thinkits the end of this boiler jst yet.

 

[bengasman]

as a leaking hex can really be dangerous, it is time to call in a pro

 

[gavinda]

unless im missing something hes got no ch circulation but hw works. no mention of water leaks. th efault occured after a draindown so the assumption is airlock.

 

[compo69]

Thanks, guys.

There's no pressure loss now, so maybe leaky hex isn't problem.
I've opened AAV, maybe it too is knackered seeing as the ex vessel was?

I had BG come round. Just did a tightness test and said boiler's too old, blah, blah, blah... They didn't even charge me - tho could give me a quote for new boiler!

Well I never, that a new approach from BG.

Looks like BG "fixed price repair" doesn't include anything more complicated than a thermocouple or pump change. Quotes for new boilers are free though.

More fuel for the fire

 

[compo69]

Hmm, I know
What ever happened to the good old days when trades would REPAIR things?

 

[snb]

you haven't closed one of the flow and return valves on the boiler by any chance when you put on the external vessel?

From what the OP said in original post its not just BG that arent willing to touch it neither are the independants. Lets face it, no-one wants to work on these

 

[compo69]

No mate. Have double checked all the obvious.
CH is working but wont raise temperature properly. Starting to think it's the temp sensor.

Totally agree pp. Tho what're ya meant to do?

That may be the case, but the BG engineer was pulling a fast one so he didn't have to do the job.
