As to bleeding radiators. Put a bucket or jar or something under the
bleeder. Leave it open until you get a solid stream of water coming out.

Ok, your boiler makes hot water. The lower floor loop works fine, but
the upper floor loop doesn't. Both circulators are running. (Are you
sure? Sometimes with vibration is it hard to tell. Turn off the lower
floor zone by turning that thermostat way down, and make sure the
other circulator is still running.) If it's not running, then you
have a problem with the thermostat, wiring , circulator, or control.


You are not circulating water in the upper floor loop; if you were,
you'd have heat.

The feed to the upper floor is hot for a while after it leaves the
boiler probably just from conduction.

Sound like the upper floor is air locked. When you bled the upper
floor, did you get out water, or just air? If just air, you may just
need to bleed it more. Make sure you bleed every radiator.

If you never get water out of the bleeds, then the static pressure of
your system isn't high enough to overcome gravity. Make sure the
make-up water valve is open.

If you don't know what or where that is, it is probably time to call
the pro.
