WORCESTER COMBI 28Si II, two years old. I am having a problem with a banging noise coming from my boiler/pipes.
If I run my hot water at anything more than half pressure I get quite an alarming banging noise and the water splutters at the same rate as the bangs. If I run the hot water below half pressure the banging stops and run smoothly. The water in both cases is at the correct temperature. The central heating side of things is fine.
