Question Way to reduce baseboard heating noises


We've just moved into a house built in 1977. It has hot water baseboard heating. Problem is, the registers really seem to make those, snap, crackle, and pop noises as it expands and contracts.

Is there any way to treat this? Is the only solution to buy a more modern version?

Thanks in advance for any advice you have.

Hi Steve,
As I replied to your post on another board, the best solution is to find the surfaces on which the pipe is moving, and lubricate it. Graphite often works, and I'm sure others here have more ideas.

Basebpard Noises


Yes, as Andrew correctly points out, the aluminum fin elements move slightly due to expansion when the hot water runs thru them; remove the corner end caps & the front cover piece of the baseboard & examine the aluminum fins; they are held up by small steel brackets every 3' or so; these brackets should have a 2" plastic piece on either side (above & below) of each steel bracket; this plastic piece allows the baseboard to quietly slide on the plastic insert, thus preventing most of the objectionable noise you're hearing; often, the plastic inserts are not placed directly over or directly under the bracket; in this case, they can be easily pulled off the fins & correctly repositioned over & under the bracket; if the plastic inserts are missing, take a measurement of the diameter of your fins & go to a heating supply store to purchase replacements; they can also be made up using any odd pieces you have around the house of plastic, or even pieces of alminum/steel sheet or thin wood paneling, etc.

Another important source of baseboard noise is the access holes thru the floorboards for the supply & return piepes for each baseboard section; if these are making a banging noise, you can use a caulking gun filled with "high heat caulking compound" (Home Depot, fireplace section); squirt a dab in each floorboard hole that is acting up.

This should take care of most of the noises associated with baseboards; there will always be some minor pings & dings heard, but they let you know the heat is coming up, so you don't want to eliminate everything.
