No Heat Out of One Radiator

KReiser

I have gas heat and hot water radiators. I recently noticed that I do not have heat coming out of 1 radiator in my one level home (the gas burner is in the basement). When I try to bleed there is no air coming out of the valve. When I feel the pipes going into the valve, they are hot, so it is safe to assume that the hot water is reaching the radiator. I change the bleeder valve and heat started coming out of the radiator for two days, then suddenly stopped. When I try to bleed no air is coming out of the valve. Also, I now have no heat coming out of an additional radiator in the room adjacent to the first room that had no heat. The house was built in the Northeast in 1960. Any help you can offer would be greatly appreciated and Happy Holidays.

You say you have hot water heat.

 Can you post a photo of your radiator?

Here is a pic of the radiator in question.  Thanks again for your help.

Steamhead

Not enough water in the system

to push the air out. The fill valve may be bad. Time to call a pro.

I agree with Steamhead, low water pressure.

The use of automatic vents is also an indication that there is a problem with air. On hot water convectors I use only manual vents to prevent air from reentering the system. You say the northeast I do service a fairly wide area of the northeast.
