I have a >5 year old Warmflow Cabin Pack boiler (oil) which repeatedly fills with water in the combustion chamber.
This was discovered last winter after heating had been off most of the summer; wouldnt fire up, loosened motor unit and water gushed out of the chamber.
I drained it as best I could and next day (perhaps after it dried out?) it fired up and worked ok all winter.
Exact same scenario this year - full of water and about 2 inches deep of rust. Warmflow engineer came out, insists its rainwater getting down the flue (it is an external flue with storm cap and I have sealed up the joints following last years discovery!).
Paid £150 forwork + new parts (including 2 baffle plates which were corroded) - advice given by warmflow is to run boiler throughout year (1/2 hour x2 a day) to ensure no 'rain water' gathers.
I suspect that there is a leak somewhere internally and they are simply trying to avoid fixing/replacing it (it is under warrenty until the end of this month).
Question is, is it common that so much water can get down a flue if the boiler isnt firing for say, 5 months in a year (it is wet here, but not that bad!?)??
SORRY for the long post but any help would be much appreciated!!
