Hot Water System -- Cold Radiator
I am having troubles with a radiator. In the spring, I drained my system to remove radiators in my kitchen for a rehab project. I replaced them, refilled the system, bled, bled again, and bled again. At that time all of the radiators in the house were heating up.
Now that it's the fall and getting cooler, it's time to run the heat. I now have a radiator in a bedroom that will not heat up beyond just a minor amount of warming. I have bled this radiator so it seems to be full -- problem is the radiator is still cold.
Anyone have any suggestions? Could there be air or sediment or something somewhere in the system that allows the pressure to remain, but not the hot water into the radiator?
