Hi, I have read some of the posts on boiler noise and just need clarification please. My chaffoteaux boiler starts up in the morning and I can hear the normal hum which is fine, then after about 30 seconds the aeroplane noise starts, it is very loud at first then after about 1 minute it drops down, then comes back in waves, slowly diminishing untill after about 5 minutes it stops. It also does the same when the HW it turned on.
I'm guessing it's the heat exchanger! I have put cleaner in the system for 3 weeks as per instruction, cleaned out and re filled with noise reducer and inhibitor but it's still there, some days not so bad but some days really loud.
Any advice please?
