Hi,
I've got an upstairs radiator with 12 vertical tubes in a kid's room. When the CH has been running for a while all other radiators are hot (inc another one in the same room), but on this one - only a few of the tubes are hot, some tubes are warm and some are cool. There is no particular order to the tubes that are getting hot. Flow is hot, return is warm.
It is a fairly new radiator.
I've bled it and gently banged it.
I can hear quiet dripping sounds inside!? Does that mean air still or an airlock (if there is such a thing)?
Anyone had any similar problems. All comments gratefully recieved.
Thanks
