The Pipes! The Pipes!
My duplex is heated by a combination of slant-fin and cast iron baseboard hot-water heat. Been here 3 seasons now with no problems to speak of.
There is a heat-pipe that runs above the drop-ceiling of my bedroom (questionable design, yes) and a few weeks ago I started hearing a rapid tapping sound from that pipe every time the heat comes on – followed by a few deep thuds which then taper off. The whole event lasts about a minute.
Anyone have any idea what the issue might be? As far as I can tell this is the highest point in the system. Could this be air in the line? The system was bled last season but not this year.
Thanks in advance.
