You have no recirclator pump on your hot water radiator system? put one

Is system steam or hot water?
It may be time to call a plumber with heating system experience
Where are you?
Just re read your original post
is the tank you talk about on the highest floor of your residence with a pipe
going thru the roof and a sight glass along the side?
So it is a hot water system we guess, hot water systems dont develop

now have air in the new water , you must cook it out before you rust
