may be time to bring in a pro and have him go over the system and then show you how to take care of the system

    Radiator problem

    Good morning.

    I bought a condo recently in Massachusetts, and as it has been getting colder, I have tried to turn on the heat. I have forced hot water, and went downstairs to check on the boiler since none of the radiators were getting hot. I purged the system, and yet the radiators are still not hot. The boiler appears to be running effectively on 20psi at around 220degrees, and the pipe in which the water is leaving the boiler is hot. The return pipe is luke warm at best. Any suggestions what this may be? When I purged the pipes, the water flow was not extremely intense. It was a steady flow of water, but definitely not gushing. Could this be a problem with the circulator? (My apt is on the 2nd and 3rd floor of a three story, and the boiler is in the basement).

    circ problem...

    sure could. I'm at best a novice when it comes to Hot Water heat, however, I do know that 220*F is WAYYYYY too hot! It's supposed to be Hot Water, not Steam!

    Thanks. So would the circulator effect how hot the boiler is as well. I presume it should be around 180 degrees. Either way, the radiators aren't feeling a drop of this heat, and I'm not sure what the issue is, since the pipe leaving the boiler is very hot.

    220 is pretty hot, but I have seen it done

    Do you have your own zone ie your own pump? If you do, you could be air bound even if you have bled the rads. Is there a purge or boiler drain on the return line? Any way you can get us a pic?

    I think I'm calling in a plumber. Unfortunately I do not know enough to figure this out on my own. Thanks anyway.
