Hi,
I would very much like you to be able to guide me in the correct dirention of diagnosis:-
I have a Ferroli sigma 60/100 boiler. From startup it runs fine for about 20 to 25 mins then starts to make a chuffing sound. Difficult to describe in words but it is rather like a steam engine. If you place your hand on the boiler when this noise occurs you can also feel the same pulsating at a frequecy of about once every 2 secs. Although the boiler is mounted on an external wall, it resonates throughout our timber frame house...very annoying. The boiler is 4 years old.
Please please help.
Regards in advance
Andy
