Hello, I have just moved in to a new flat this week and have a problem with noise coming from somewhere around the top of the boiler.
It's a loud clicking/knocking sound that lasts about a minute, stops for 20-30 seconds and starts again. It seems to happen at night, starting in the evening, and got pretty bad at 3am last night. I switched the boiler off completely and it continued for about 3 hours after that.
I have a video of the noise it makes: youtube.com/shorts/EgtfGtKBawA
It's a Worcester Bosch Greenstar 241 Junior.
Would anyone happen to know what might be causing this? Thank you.
