Just had a new boiler (glow-worm) and pump fitted. This has resulted in 'banging' in boiler, only warm radiators, and very hot water in tap. Plumber has drained. descaled, drained, cleansed, and drained and put in inhibitor. Boiler still 'banging'. Have tried pump on all 3 speeds - makes no difference. Plumber has now suggested we change ALL radiators to eliminate problem!! Boiler only runs for 1 min and 20 secs from start up - takes 30 seconds for 'banging' to kick in, and then switches off for 2 mins. Turned heating off and run HW only - no change.
