Banging Noise – Central Heating

· Possible cause is air in the central heating system – bleed the radiators.

· Is there enough water in the central heating system?

· Tightly fitting pipes – as the water heats up this causes the pipes to heat up and expand.

· Sticking valve – a ‘light tap’ with a hammer frees a lot of stuck central heating valves.

· Scaling in the system – add a de-scaler to the central heating system.

· Pipes not secured – pipes can move when heating up, the banging noise could be the movement of the pipes.
