bleeding radiators
We have steam heat from radiators, we were told different ways to bleed them (let the air out). Can anyone tell me the proper way to do it so we get the most cost effective heating. Thanks

If you have steam heat, you do NOT need to bleed the radiators. They would have an automatic vent on them already or a trap on the outlet to allow water and air out. If the radiator isn't getting hot there is probably another reason. It may have settled preventing steam from reaching it or a trap may be defective. Does each radiator have a vent on it now?

AND
how many pipes does it have attached to it?
Is the problem one or two radiators or all of them?
What are the symptoms?

bleeding radiators
Thanks for replying there is 1 pipe connected to it, the only problem were having is with the 1 in the attic. It gets hot, but not as hot as it should be. We were told 2 different ways to bleed them. The first was to start closest to the furnace then follow in that order, the other way was to start with the farthest away from the furnace. So were not sure how to bleed them. any & all help would be appreciated.

adjustables
NO, you misunderstood! You don't bleed anything on a staem system. Many systems have what is refered to as adjustable air vents. They allow the air in a steam system to be purged so that the space where air once existed can be replaced with hot steam. The goal is for all radiators to heat at the same time, from one end to the other. This can be done using adjustable air vents. You want to make sure, the one farthest from the boiler is open the most and the one closest to the boiler is open the least and the others are graduated in between. Some makers have a number 1-9,...I'd try for one of those stlyes first, and use the trial and error method to adjust.... there's no big rush.... One thing I would do is replace the main vent usually at the end of the main about a foot from the end. These are usually 1/2" or 3/4 ". This vents the main only, then the small ones do the branches. Make sure your boiler doesn't go over 2 PSI before the boiler cuts out, if it does, it should be adjusted to about 1.5 PSI and cut in at about .5 PSI. Watch it cycle.
