can you ELI5 the physics of bleeding radiators on an apartment building? - eviltoast

I live on the 14th floor of a 30 story apartment building and so far, I’ve been bleeding my radiators myself.

This usually worked and after bleeding I had a fully functioning radiator, 100% filled with water.

However, last time I tried bleeding, it would only fill up to 25% of its volume, it’s like there’s no pressure in the circuit.

Am I doing something wrong?

    Great answer, there should also be a pressure gauge somewhere on the boiler. As mentioned, this is really for your building manager though.
