Thought I'd start a thread for people with boiler kettling and various bangs. The chemicals do work !
Ours started getting a bit noisy in early autumn - hadn't really noticed until we've stitched the heating on. The system has had inhibitor and anti-noise fluids in the past, but not for a while.
Water was inky black though !
Dropped some additional anti-noise fluid in the header tank and sludge clearer. Let that run for a couple of weeks.
Then drained down the system - left the ball cock open for the header tank as didn't want to bring in air. Hose to drain point of kitchen radiator, drained into sink (enough pressure to push the water up 4 feet into the sink). Drained until water ran clear, ran heating pump, then drained again. Repeated over a few hours (letting water circulate in between opening the drain).
Ordered some trade inhibitor (5 litres for £40 and some boiler silencer). Popped in a litre of boiler silencer into the header tank and 2.5 litres of the inhibitor in. This was more than recommended inhibitor, but it does no harm. Drained down a few litres of water from the drain point.
Left it running and over about a week the kettling has stopped.
Was only doing it when the heat exchanger got hot, so quiet as a mouse for a couple of minutes, then started "fizzing". It would continue "fizzing" when the gas shut down, until the heat exchanger cooled.
So, if your boiler is making noises, check your water, then add inhibitor and boiler silencer.
