CO dangers & open flue v room sealed

[Reg Man]

Open flue boilers have an incident rate about 12 times that of room-sealed Boilers…

Check this document out. OK, the data is a bit old but...:

2005 but still relevant.

Defo!

I'm copying that into the CO Incident sticky in the CH forum. Cheers Alex!

All clear to me now.

Did not see original post from you Mrs T. with the explanation.Hope no offence taken.

Lol, Mrs TP is unique in being our only non-gsr gsr badge holder!

 

[Mrs Tara Plumbi]

All clear to me now.

I'm not offended,
I'm the director so it is my GSR no but obviously I do not have an operative number. my husband does but I wouldn't want to pretend to be him. that would be mad.

Is that an open invite? :devilish::wink_smile:

Down, boy! :rolleyes2:

As a young BG gasman working in London I can remember the relief i felt when room sealed appliances became commonplace, this was because of the amount deaths from carbon monoxide I sadly witnesses or heard about due to OF appliances at the time.


Im sorry to say due to the lack of air pressure switches on HE boilers we have taken a step backwards and now again we are seeing needless deaths.


I would advise any gas fitter who doesn't have flue paronia to devolpe it quickly, only recently I got PPM readings in a child's bedroom from a flue that had disconnected in a void.

It's a good that more and more detectors are being fitted and that some manufactures are fitting carbon monoxide alarms in their appliances but even with this we have to be careful out there.

Am I correct in thinking and saying

1. that roomed sealled appliances are safer than open flued appliances?

Is there anything I'm missing?

Quitea bit actually. With respect it's a foolhardy question. Whilst OF Appliances are more susceptible, ANY Gas Appliance is capable of producing CO. I am sure that plenty of Engineers here have dealt with dangerous RS CH boilers.

Yes we have dealt with room sealed boilers producing CO, but re-read her a question then answer it, is it potentially more dangerous if the boiler producing the CO is OF or RS?

I read it. I gave MY answer mate, no need to be facetious

i agree with that one hundred percent condensing boilers are definately a step backwards in terms of safety positive preasure burners pushing fumes througheven the smallest gap in burner seals , acidic liquids escaping and rotting components and flues away ,a down firing burner defies the physics of heat transfer
funny thing is when they were bringing them in we were told the acidity of condense was as safe as orange juice im yet to see a rep drink it to prove the point

Ok then, why was it a foolhardy question she asked? It was a straightforward question which a lot of people answered, then you chipped in with no help at all with your answer, so explain how your answer helped in any way, because all you said was that we worked on RS boilers which produce CO, then I asked you to comment which was more dangerous producing CO, RS or OF and you didn't answer, so in your opinion which is more dangerous, then tell me why it's a fool hardy question, PS what does facetious mean?

With the Nitrogen content may be better for him if he is a Plant ( Fertilizer !)

Is there a nick-name for Boiler rot ? (excl "Corrosion")

So in summary: any gas appliance which has an air passage back into an enclosed occupied space whether intended to be or not is more dangerous for co than if it is sealed off from the enclosed space. So as a general rule OF is more dangerous than RS, even when installed correctly.
