Hi, I have a Ferroli Combi 77 FF. For the last 12 months it has behaved itself but as of last week its started to make a curious and rather ominous sound. It's difficult to describe but it's now louder on start up and stays slightly noisier.
Once running it falls out of step at random. It sounds almost like wind blowing across or down the flue and then it recovers. Sometimes it's fine for minutes other times it makes the wind noise almost every ten seconds before recovering to normal pitch.
Hot water and central heating still work. The pressure doesn't change on the dial and looking through the little view hole the flames aren't effected when the pitch of the noise changes.
Could it be the fan finally giving up or similiar?
I don't know the age of the boiler but it would certainly have a few candles on it's birthday cake.
Any info much appreciated.
