When I bought my house with oil fired boiler and radiator heat, the system constantly became airbound. As long as it was cold and the boiler ran, it was OK. But if it got warm for a few days and the boiler didnt run I had to bleed the radiators. This ammounted to once a week. Sometimes every other day. The "pros" said leave it alone and just bleed it. Then I saw a friend install the same system in a house he bought that was electrically heated. The guy did the installation over the summer. I saw a widget on the boiler I didnt know what it was. He told me it was an automatic air bleeder. I found out I could get them in a size to replace the air chambers on my radiators. 11 in all. Also, I installed a diaphram type of expansion chamber to replace the old expansion tank.
It works great! No more problem. I wonder was installing the auto bleeders on each radiator overkill?
