Here’s a puzzle for you: My downstairs radiators work fine, and kick a lot of heat. My upstairs ones, however, are only warm at the bottom, and are cold on top. I’ve tried all the various fixes I’ve found on the internet: Bleeding the radiators, bleeding them in a certain order, etc., but I still can’t seem to fix the problem. When I bleed the downstairs ones, water comes out immediately. Upstairs, I can bleed a bit of air every day, but no water ever comes out (and recently, I can only bleed air from the first radiator I attempt to bleed upstairs, nothing happens with the other two). What’s going on?
I’ve read that I might need to add water or pressure to my system, but I’m not sure how. The pressure gauge on my boiler usually reads around 10 PSI or so. I found a reducing valve (or feed valve, a Bell Gossett one with a lever), but I’m not fully sure how it works, since I don’t know which position is on and which is off; and I’ve tried running the system both ways and it doesn’t seem to make much of a difference.
Does anyone have any insight or suggestions? Is there anything easy/obvious I might be missing? I just bought the house this year, and the system is pretty old, but otherwise seems to be working alright (I just had a furnace guy inspect it a few months ago).
