I was trying to bleed one of my radiators in my house today that hasn't been heating properly, and it just kept hissing air....no water came out. I tried several times, for about 20 or 30 seconds each time but still nothing but air. And the air that was escaping smelled a little gassy. Any thoughts on what might be wrong? Or should I have let the air keep running longer, i.e. might it still have discharged some water eventually?

FYI, even though I never got it to bleed, just the attempt seems to have worked....it started heating (big time!) last night. I'll still probably give it some more tries, but at least it's working now.

the water level may be too low in the system to reach all the way to that radiator. your boiler will have a pressure gauge on it that shows how high the water pressure is. most newer boilers have an auto fill valve on them and will gradually add water to the system. if you live in a two story house, the gauge should read about 13-15 on the dial. there are water valves to let water into the boiler and there is the auto feed valve too. also there might be a chance that your expansion tank needs to be drained. if you have one of those it should be in the ceiling above the boiler. some newer boilers have one the size of a barbecue grill gas tank in the piping instead.if you haven't had the furnace serviced yet this year, you may want to consider having it done and have the service tech show you the proper steps to fill and bleed your system. it's more of a show you, than tell you how to thing. good luck, hope this helps. oh, the odor from the air and or water is nothing to be concerned about. it is a combination of oil and water and rust and that kinda stuff. kinda like how cars have their normal smells. also, when bleeding them, start with the one the furthest from the boiler and work your way back towards it. as you have already seen, the air rises to the highest and furthest

Sometimes it can take ages to bleed a radiator that hasn't been bled in a while especially if its at the end of the chain... i.e. furthest away from the boiler.

If you start at the boiler and bleed each radiator in turn it might help.

If you touch the base of the radiator when its 'on' and it is still cold then chances are, no hot water is even reaching it and you'll have to back track. There may be an airlock in one of the others that will need to be bled off first.

First off, what kind of radiator is it? Bleeding only works if it's a hot water-based radiator. Some radiators use steam and if that's the kind you have of course it'll keep on going because you'll only be letting out steam.

If it really is a water radiator, just keep it up until you see water regardless of how long it takes. It's possible it could take minutes until you see water.

I would let it keep running, but maybe check with a place like Hoem depot..

Might check to see if your valves are clear. It's a good idea to change them from time to time.
