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?

similar noise problem with baseboard...solution

your right with the expansion causing the noise. I recently was called to a baseboard job where home owner complained of noise keeping him up through the night. Problem was where the copper pipe passed through one room to the next, they  put  wallboard compound on it all around so it had no room to expand. Pipe was rubbing against wood support and making noise. make sure all parts of pipe are resting on brackets and can move freely, your problem should go away. when you dropped text book on it you probably bent it up so its binding on something again. look at it carefully at area where  noise is loudest, you'll see the pipe is probably hitting something
