Yes, I did mean air, not steam. We have a gas boiler which heats a tank, which in turn pumps the hot water to the radiators. Nothing unusual there. Some rads. are over 20 years old, some 10 years, two are recent. We have only noticed the problem since the installation of the most recent one...

Several radiators are cool or cold at the bottom half. I have bled them all but no steam came out. Any suggestions?
