Water baseboards generating clicking noise

Dezso3

My room is heated with a hot water baseboard heating system. As soon as the system was installed, it was making clicking noises. I figured out a way to attach the pipes to the baseboards, and the clicking noise went away temporarily. Just



recently, I accidentally knocked a textbook from my desk right on top

of the baseboards, and after that, when the heat came on, they started

clicking like mad, all over again. What I have noticed is that the

pipes and the metal baseboard covers only make the clicking noise if

the covers are attached to the support brackets; if I remove them, the

clicking ceases. I believe this is because when the covers are on, they

pull the support brackets tightly together, which increases tension

between the support brackets and the pipes. When the pipes heat up and

begin to expand, they do not have enough room to do so, and it results

in a clicking noise. However, I am not positive that this is what is

creating the noise. It's extremely annoying because I



wake up early in the morning whenever the heat comes on and cannot sleep. What the heck can be done about this?

Reducing the sound

Some manufacturers (Slant-Fin) have several plastic (spacers per piece) attached to the fins, that act as a spacer between the cover. If the fin tube is not setting on the brackets correctly, and is pushed forward to touch the cover, it will make noise.  The piping to the baseboard may also be contributing to the issue, if not plumb and square to the correct centerline of the BB.
