Hi
I had a combi fitted last year, since then I have changed and added some rads (the boiler I brought was big enough to take the extra rads) and re piped the cloakroom. I have noticed that in the mornings the pipes bang. No heating is on and no taps have been touched, everyone is in bed. I checked all rads for air, but that wasn’t it. Checked all taps for air and not that either. Googled this but can find no information anywhere. Any ideas?
Thanks Steve
