Chaffoteaux boilers are a bit prone to make sometimes alarming noises - problem is poor circulation through heat exchanger caused by debris or a clogged CH return filter. The engineer may not have known about the filter (it's hidden away, if there is one - see manual). Best to check this first since it's a much cheaper repair. You could also try just flushing the heat exchanger to clear debris. Again vastly cheaper than complete system power flush (which may not even be necessary).
