Air in a closed system? (Valve only opens when the p(in) > p(out).
On cooling is partial vacuumed.
bc thinks a leaky system would result in sickness (mold)

That is basically what I said in my original posting. Sometimes therelief valve get stuck. That radiator remains cold while all the rest
in the house operate normally. If the valve is replaced, the radiator

One set of my grandparents had a one-pipe steam system. It was
me that the vent was to let the air out. This makes sense. When thesystem
starts up, there is air at atmospheric pressure in the radiator.
