Re: Furnace -- missing water

Single-pipe steam is not sealed. As the heated steam rises, it pushes air out through the system via vent valves located at each radiator.

Thanks. I guess I thought steam just eventually rose, condensed, and ran back down. Probably works a little faster if the room temperature air can just be pushed out instead.

...and too much venting will/may lead to drop in water level and knocking in the system.
