My boiler bangs when on, worse when starting up.... I'm thinking of using boiler silencer in the F & E. IS this any good?
The pump's ok, set on speed setting 2 but tried on 3 and still same. The boiler has no overheatstat, and flame pic is good. I'm thinking as it's an old boiler (20+ years) it's a scaled/sludged heat exchanger. It works fine, on hw and htg. Have a grundfos pump with 3 port mid position valve (Honeywell) - all is ok, just a bit noisy and sounds louder when tv is off!!
Anyone used Fernox? Or any other dieas what the noise could possibly be?
