I keep losing HW pressure?

My convector's keep losing pressure and need constant bleeding (air in the top of the units). Certain ones mind you. (Heat System which runs units throughout my house.) I will change out the bleeder valves first chance I get. I am assuming air must be leaking thru the threads. Most likely caused from corrosion of the two different metals.Brass/copper and Steel.

Much more likely that you have a water leak. Do you have any areas that show a fungus-like build-up? What type of air vents do you have?

Are you saying that you are able to bring the pressure back up in some way?

What do you read on the boiler pressure/temperature gauge?

Yes there are sign of corrosion build up. But allot of them are getting good flow.
