The boiler is brand new only installed around a month ago.
System is clean with magnaclean in the return pipe work.
At aroung 55-60 degrees C a light rumbling/whistly sound start only to get worse the warmer it gets. it will finally sound like a helicopter above. the boiler does vibrate a little at this stage & it sound very unhealty.
It will never fail on any fault codes.
I have it downrated to 15KW and there are no noise problems & it purrs along beautifully.
Any Ideas?
Regards
Vin
