clanging, gurgling from recessed convector radiator
I have a one pipe steam heating system. Everything seems to function quitely and efficiently except for one radiator (out of 10). This radiator is a recessed cast iron convector. Problems: We hear a series of clicking, then clanging (almost metalic sounding) right before the hammering sound begins. Soon to follow is a gurgling sound (sounds like the steam is boiling trapped water in the radiator). This gurgling sound actually persists the entire time the radiator is being heated.
The vents on all the radiators are new (10/2012). I have even replaced the vent on this above mentioned radiator a few days ago and the problem still persists.
If I could, I would remove this radiator to assess it up and down. Being that it is recessed, it's going to be tricky to get it out of the space (getting a wrench in the tight space below the cast iron frame to loosen the nut is a hard enough task).
Any thoughts of why this is happening? My guess is that there is trapped water from condensation somewhere in the radiator piping.
