Re: Furnace -- missing water

said by PhoenixDown:

I don't keep the auto-fill on (never have) so I just fill 'er up once or twice day as needed.

I've always lived with a gas forced air system, so hydronic and steam systems are a bit foreign. But aren't both of those sealed systems, meaning that you shouldn't have to add any water on a regular basis, let alone once or twice a day?

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.
