The boiler is 25yrs old. There's a high /low switch on the boiler set to high.
Boiler in kitchen. Immersion tank, pump etc are located upstairs in a cupboard.
2 radiators downstairs and 3 upstairs.
Over the past couple of months we've had an intermittent clanging noise from the boiler, pipework or pump. Can't hear it from the radiators.
After clanging for 5 seconds the boiler stops, waits for a few minutes, starts up and then runs fine. I can't recreate the issue to better locate exactly where the noise is coming from.
I've bleed the radiators from each of the valves using a key and the pump via loosening the large brass screw. The water is clear.
I'd be much obliged if someone could suggest what the problem could be please.
Thank you
Richard
