Hello,

I think that when it rains hard in a certain direction the flue on my
condenser boiler lets in rain water. This then runs through the boiler and
drips out from the bottom front corner. Does this sound possible? It is
definitely rain water as it never happens when it is not raining.

Any ideas on how I can prevent this?


Thanks,

Graham


Today I tried to find the source of the leak, I stripped the boiler down as
far as I dared. It seems to be coming down the righthand side of the inside
of the air box, between the air box and the combustion box.

So I reckon it is either from the flow or return into the heat exchanger or
something to do with condensate from the flue at the top. The condensate
trap seems to be filling and emptying correctly and is clear of debris.

The next stage I reckon would be to remove the heat exchanger assembly, but
for this I would need to drain down. The wife wants to call someone in, I am
near to agreeing with her.

One question, as the water in the system is under pressure then wouldn't the
leak drip all the time rather than just when the boiler is operating? If so
then it must be condensate, mustn't it?
