2011 ended with the complete breakdown of the boiler. It started off on New year's Eve just leaking a bit. The gas men arrived in the afternoon to strip it down and find out what was wrong. After 4 hours the boiler wasn't working at all - no heating or hot water! But they now know what is wrong. It's the heat exchanger - the most expensive part. So much for these compulsory condenser boilers we all have to have fitted. This one is the most recommended. 5 years old and virtually needs replacing! Still they did give us 4 fan heaters to keep us warm until the parts can be replaced!
