Problem: hearing clicking metal noise when water-based heating is on.
Because this sound travels so quick, it was very hard to find the spot, but finally found it – right below the outlet.
Opened the wall, here it is:
Black pipe in the back: water-based heating.
The three pipes at the front: electrical.
Note that the middle pipe is not straight – maybe a problem during construction? instead of side-by-side/aligned with the other two pipes, the middle pipe has a bend going a little behind. It is touching (ou super close to) the heating pipe and causing the clicking noise as the heating pipe expands/vibrates.
What do you guys suggest? For example:
-
Just putting something (insulation) between the middle electrical pipe and the heating pipe to stop the clicking noise?
-
Cutting the middle pipe and installing a Z join (not sure if there is enough space).
All ideas are welcome.
Thanks!

A little window and door, low pressure expanding foam will do the trick. Be very careful around those pipes they are in very bad shape. Don't pry or push on them. You are going to need a complete overhaul of your heating system if they are representative of your system. I'd start putting money away if I were you.
Don't use the regular expanding foam. It creates enormous amount of pressure.
