New boiler worry

gas4you

Yes, They are fine.

No need to worry about the minimum only being 9.1%.

What did he have to say about it?

Excellent, thank you. Was worried it still was not right only being 9.1. This would mean the 5 year warranty from WB would be valid wouldnt it (still being out by 0.1%)?

I never spoke to him (I was not here, husband was here). He barely said anything to my husband.

His colleague when he first came round put the two pipes (return/feed) into/from the boiler the wrong way around! Lucky my husband realised, as he had looked at the installation manual

Surely the boiler will be set within spec out of the box anyway? Gas valves on most if not all domestic forced draught burners would be preset and sealed to avoid twiddling. I think this is mainly done to ensure safe operation of the boiler from new and to avoid twiddling by people whether gas safe or not,who do not really understand th combustion process and therefore might be in danger of creating a situation in which high levels of CO are produced.

So OP..dont worry..as long as he hasnt !!!!!!ed about with it,it is likely to be preset out of the box by WB.

Not sure what he has done, he has changed some settings as the c02 was too low the other day

I can count on one hand the number of boilers I have fitted that don't need adjustment out of the box. They shouldn't do, but then there is reality.

Yes your WB warranty is fine with those readings, but remember to retain the warranty you must have it serviced by a RGI each year.

From your experience this time, I would suggest someone else!

Thanks Gas4you, I will not be using this guy again.

Glad the readings are almost there now. Lucky I realised I guess - I never had any idea until I read the installation manual. I shouldnt have to tell him his job. He said he was coming back for "peace of mind" - more like he knew he did wrong.

He started this job on Thurs 7th June, came home and the boiler was too low down (nearly on worktop!). I said I wasnt having this, so his mate (who put the pipes wrong way round on the boiler) took boiler off of the wall next day and bricked it up. They came back on Monday 11th and left it working. At this point he HAD NOT COMMISSIONED it - officially. He came back on Friday 15th to finish it in. Then officially commissioned it. He said he should have commissioned it on on Monday but no time, he said he had checked the readings on Monday and they were ok. Surely he should not have left it on the Monday switched on and without properly testing or recording it should he?

In a perfect world, no he shouldn't, but he would probably class it as 'work in progress' to cover himself.

A new boiler should always be 'run in' for a few hours before commissioning it properly, as the protective oils etc that are on the heat exchanger metal will give off fumes that will affect the readings.

I usually try to get the boiler up and running by the end of the day, leave it running overnight, then commission it properly first thing in the morning.
