Freezing Cold boiler wont stay lit

How long has boiler been fitted?

Don't think it would be the wind, otherwise loads of other people would be having the same problem. It sounds like it could be low gas pressure on firing. You may find that the main run of gas pipe is ok, but the engineer may have reduced the diameter closer to the boiler. As Karl said, the initial 'pilot light' ( I know it is electronic ignition, but it will need something to light the rest of the burners) could be lighting, but the pressure goes down on gas being let out into the burners, so therefore it cuts out.

I know a fair bit about fires, but only general on boilers, but Karl..... Is it usual practice to check gas pressures at meter and boiler when servicing a boiler? If the engineer just cleaned it out and not checked the pressures, it could be that the gas co has been work and your pressure has changed. Maybe worthwhile getting gas co out to check pressure into house. Otherwise get a ' better' engineer in to check boiler out

I doubt it is anything to do with the wind. Will be gas related. Get a different gas engineer in to look at it?

I always check gas pressures ( working pressure) at the meter on a service, as well as doing a tightness test. I know it is not a legal requirement, but how would one know an installation is safe and working properly without doing these very basic tests?

if the ignition/electrode is burnt away
as canuckhead has said in earlier posts

that could cause misfiring as the electrode
wont pick up heat in high winds

Sooooo, getting down to the nitty gritty then.

Any other problems with the installation?

Only an RGI can tell you what you ask, it's calculated out according to the property, not as a 'rule of thumb'

I cannot see why a properly installed boiler would suffer from wind!!:)

at the end of the day
the boiler could be absolutely fine :j

but the high winds playing on the fan :mad:
could simply cause the diaphragm not to engage permanently
in the air pressure switch :mad:
therefore the double pole switch contacts consisting of
common ( live ) normally closed, and normally open in the air pressure switch which are switched ,live back, from the relays on the pcb,
after the fan is proved for safety do not reamain closed/on

pps.........22mm gas pipework to the boiler is the norm
