When I am in bed before the heating turns off, I am driven mad by a ticking noise. It sounds like the pipes or rads are expandind/contracting. I`ve had the boards up and made sure that the pipes are not rubbing on the joists. I`ve sprayed WD40 everywhere that could be moving against anything. I`ve run out of ideas, if anyone else can think of anything I would be grateful.
Cheers.....
