heatline C28 boiler provides a low ch output ?

Sorry, not an answer, but to say that ours did/does exactly the same (in Dec 2009) but four days before Xmas a friend helped me flush out the whole system and re-fill (with inhibitor) as he thought it may be an air lock. System then worked, and has done CONTINUOUSLY without pause (dread to think of the bill) until TONIGHT when I spotted water leaking out of the bottom of the boiler... so no heating/hot water now, as I await the dreaded visit by a boiler man in the morning! But ignoring my major problem, this is the third instance I've read on the internet about problems with this boiler. :-(
