Hi everyone .....and a very good evening to you all.
Can someone advise me why our boiler starts to bang for about 4 times or so, when it stops firing and reaches the set temperature.
It doesn't do it when it fires up or during the heating cycle - only at the very end some water noises also appear present in the boiler at this time.
I was having more regular noises/ banging, at all points of the cycle, (advised it was possibly a scaled up heat exchanger /pipework) but ths has now stopped following partially draining down the sytem and putting X200 into the F&E tank.
It's just these several bangs at the end of the heating process that now remain. I have fully bled the system twice over the past 3 days following the dosing with X200 and all appears AOK with the rads etc. I have also turned the boiler thermostat down to 3 / 3.5 as an added measure but it remains the same.
Boiler is Glow Worm F100 - about 12 years old
Any advice / help on this would be very much appreciated. Regards and many thanks in advance.......Pete
