Combi Boiler problem

Immediately Dangerous (ID) is the highest level of risk and if Products Of Combustion are leaking into the property irrespective of what they were and how much he has no alternative but to ID it and shut it off. Correcting an ID problem doesn't necessarily demand replacement although with a Powermax its almost a certainly.

I would agree with getting someone else in.

Only if what the engineer said is true

Mt first suggestion is to get a second opinion-and if that does confirm the diagnosis, get a local independent GSR RGI to quote, rather than BG.
Did he really tell you it's leaking CO and CO2, did he tell you what parts needed replacing, or was he just interested in getting you to obtain an install quote from BG (which will be about 30% more than anyone else?

BG will be more like double for a good boiler or more.

How do you know ?

If he's assessed it as ID then he's 100% correct - thought that was obvious. I was trying to head off the "thats BG all over - condemn a boiler unecessarily just to get a replacement install" accusations. In the case of your post above I didn't succeed.

You know as well as I do the Powermax story or at least you should.

He showed me his test meter running with the probe still in-situ. It was showing readings for CO intermittently and CO2 all the time. I asked what was the pass/fail level and he said there was no tolerance on either of them and they must be zero.

He told me what needed replaced and that the part was not available. I've had this confirmed by a local guy who is coming on Monday to give me a quote.

Make sure you get a second opinion ( I used to work for BG )
I know of engineers that used to turn boilers off all the time ,some should not of been turned off.
Did they try and get you a sales man round to sell you a new one.

I'd need to get the gas supply re-connected to run it and get a second opinion. Will someone re-connect it when it has the BG "Dangerous" tag on it?

He did offer to get a sales quote arranged and someone is coming tomorrow (Sunday) to look at it and arrange the quote.

I used to be a sales man for a while at BG , don,t trust all that they say,
If you buy today they will give you £100 discount etc etc.
A local guy will be hundreds cheaper and will do a much better job in my opinion.

Roughly what should the cost be to supply and install a boiler? The property has 2 bedrooms, 2 public rooms, 8 radiators to supply. It will need a new flue through a flat roof directly above the boiler.

BG has no legal authority to disconnect your boiler unless they seek your permission to do so.

Did they?

Second opinion required.

Absolute poppycock.

ALL boilers will produce CO and CO2 readings when running.

CO2 % will be anywhere between 5 and 10% on average and CO readings will be between 15 and perhaps as high as 160/180. Some manufacturers say that anything below 200ppm CO is ok.

The ration between co and co2 should be less than 0.004.

I now doubt this BG engineer completely.

this is from the flue or test point, not in the room, you shouldnt get anything in the room from boiler.
