Question

Noisy baseboard radiators


Hi. I bought a one-and-a-half story 1930s house a few weeks ago and found that the baseboard radiators on the main level are very noisy when the hot water heat is on. The upper story radiators are not nearly as obnoxious. It's very distracting and sleeping is a problem.

I had a guy from a heating company out yesterday, and he said there was nothing to be done, short of switching off the heat supply to that zone, which isn't feasible since I live in Wisconsin.

I could clean and dust the "fins," which I haven't gotten around to yet. But is there anything else I can do to reduce the noise?

Thank you!

when I think of noise in baseboards its usually a gurgling or water rushing sound, and yes something can be done about that! Remove the air from that loop

Expansion and contraction maybe.? When it gets hot it expands the system and makes weird noises.

It's pings, clangs-- basically little snapping and popping sounds. They get louder the longer the heat is on. Yes, I believe it's the expansion/contraction when water goes through the fins and pipes.

How do I remove the air from the system? Is it complicated?

Thanks!!

Ayuh,... Many times expansion noises are from the tubing rubbing on things it shouldn't be rubbing on...
Close inspection of the lines sometimes leads you to where you can move things abit to gain clearance...

If you're not hearing gurgling, 'n bubbles,... Bleeding won't help a thing...
If it's heating as you say,... It's not air-bound anyways...

Look to see if the baseboard is held off the brackets with plastic brackets or not. if they are missing, you will get noise.

I have a house built circa 1960 with the same issue. I have been here 18 years. If its any comfort after a short time you will get used it. I barely notice it anymore, He is right, there isn't much you can do. The suspension system in old baseboard is primitive. Also normal settling of the house may have created some small deformities in the system. I made sure all the covers were on tight and created a couple of creative supports where some were missing. I looked at replacing the baseboard, but that would likely involved dry wall repair, repaint etc and a huge expense. The old baseboard is much taller than newer styles. Also, when I replaced my aging circa 1960 boiler with a new one which heats much faster, the expansion noise is over quicker.
