1 in 5 radiators work in zone

I've tried to bleed the air, but no air hisses out. The return pipes are dead cold. The thermostat seems to be okay: it moves up and down with a pliers.
thanks for any tips

Is the pump running when you try to bleed it? If you don't get air, do you get water? Is the radiator pitched towards the return pipe?

What needs to be determined is if this is a hot water system or a steam boiler.
The pressure reading off the gauge on the boiler would be helpful.

Pictures of your boiler and piping would be an even bigger help.

It has to be hot water. It can't be steam with that type bleeder.

it's hot water. no idea about pressure, beyond my skill level.

Tried to bleed it when heat was cranking, so I guess that means the pump is on.
Will send pics when I next go to the cottage.
thanks all!

No, it's not beyond your skill level. There must be a pressure/temperature gauge mounted on your boiler.

Please explain the type of building, 1 or 2 stories. What is the pressure on the boiler, either in pounds or feet? When you bleed the radiators do you get air, water, or nothing? When you say it moves up and down with pliers, what are you talking about? What kind of boiler is this? Pictures of the boiler, radiators and piping would be helpful. If you can't supply this information it may be time to call for professional help.
