Boiler Condemned After Completion

Milliewilly

The homebuyer survey that was done on my property a few months ago the Surveyor wanted to see the boiler working and then checked all the radiators got hot and the hot water got hot and asked to see the service record and put the gas fire on and light that!!

There are many reasons why a boiler may be spilling carbon monoxide eg blocked flue, inadequate or blocked ventilation (many people block the air vents to prevent draughts in very crafty ways to avoid detection...a lethal habit), wrong gas/air mixture (yellow flame), blocked heat exchanger, failed seals on inspection covers. The first thing to do is to service the boiler and carry out the standard safety checks. Only then will you know if the boiler cannot be operated in a safe manner.
There is an underlying assumption that the CO monitor was working correctly, had not been set-off by another gas appliance ( gas fires often spill if not serviced regularly) or even a candle. How close to the boiler was the monitor.
The OP was absolutely right to have the fault investigated, but there is no need to condemn the boiler without proper checks.

When my partner's parents boiler almost killed him 6 years ago, I ended up calling out the transco man and he didn't actually need to turn it on to check it either. He just looked at the extreme amount of soot around and behind it and condemned it on the spot. Said it was the worst boiler that he had seen in 20 years of working.

Thanks everyone.

I'm getting a second opinion tomorrow. The boiler had a load of black stuff coming out of it and apparently it would have been in the state it was in for at least 6 months.

Unfortunately it has taken over 6 months to complete so may not have been picked up in the survey anyway.

Oh well, at least I know what to look for next time and I can stay with my parents over xmas.
