    Default Boiler Radiator Cold

    How is it possible that a 3 ft section of one of my radiators is cold (on the end opposite the inlet). If there was a plug in it, wouldn't that prevent the water from circulating through the rest of the system?

    Maybe it's a steam system, not pumped hot water?

    This boiler system pumps and recirculates hot water. The temp. is set at 180 degrees, and the pressure is 20 psi. The radiator in question is an 8 ft baseboard-style rad, which is warm at one end and cold at the other end, with the middle being neither warm nor cold. All the other baseboard radiators are working properly, with the entire radiator being warm. This room is not as warm as other rooms in my house, which is why I want to know how to address this problem. I doubt the radiator is frozen, because it is not on an exterior wall.

    I was under the impression that water must circulate through the entire radiator in order for it to return to the boiler. Am I wrong?
