I will begin with saying that I have no experience with radiators whatsoever, but am mechanically inclined. I live in a semi-old house that I'm renting as a college student. We live on the second floor, and it is plenty warm on this floor. In the attic on the floor above, however, it is very cold. There is a rather large radiator up there (the whole house uses radiators) but only the bottom of it gets warm. There is a valve that controls the flow, and it is wide open.
Someone suggested that I open the bleeder at the top to bleed the air. I tried this, and some air escaped. However, no water escaped (even after leaving it open for an hour). The temperature of it has not changed -- the top and middle are still room temperature. I'm starting to wonder if the system is low on water, but I do not know how to go about checking this and how to refill it. I would HIGHLY appreciate any help that you guys can offer (but please don't get too technical with the heating-specific terms, as I am new to all of this radiator stuff).
Thanks!
