I need some advice on bleeding my radiators.
Bought an old house, 1800's, and the upstairs radiators don't heat up like downstairs.
There is a pressure gauge in the basement that says 20 lbs pressure and has automatic water feed.
I let the air out of the ones I am having problems with but the water doesn't seem to be rising up in the radiaoor and the air noise stops after a few seconds.
Can someone help me?
