I have a Ravenheat CSI primary, fanned flue boiler (12 months old)
9 radiators fitted with Rad valves.
Manual bypass, cracked just open, (if I open too much, rads don't get very hot)
System was power-flushed at installation and has inhibitor in the system.
Pump running on setting 3, have tried setting 2, no real change.
Every time the boiler fires up, there is a noise like a bandit dive-bombers coming in at 12-o-clock (I used to love those old films when I were a lad)
It has always done this, but more noticable when the heating is on.
Getting to be worse than Chinese water torture - no joke though...
Any Ideas??????
