Hi there, I was reading some posts about central heating and crackling. I think I have the same problem as you, my boiler is valliant eco pro Drayton trv4 valve on my bathroom towel rail and my dining room radiator witch is on the same wall but on the other side both crackle I'm guessing it's the bathroom? How did you solve it? I see the post was ages ago but I'm hoping you can remember thanks
