Bleed air from steam baseboard

mmc239 Member Posts: 81
My living room has steam baseboard which seems to have alot of air in it. Is there a way to bleed air from steam baseboard? When I turn heat on, while it’s heating up it bangs and spits water out of air vent which I just replaced and is brand new. Once the baseboard is heated up it’s fine.

    A more detailed explanation of the type of baseboard, it's size, and the type of steam system you have. Is it 1 pipe or 2 pipe steam? You said it has a vent which would indicate a 1 pipe system but that is not always the case. People do strange things.

    Your issue is most likely water in the radiator not air. The water which has condensed from steam is not draining out. Baseboard radiators are considered tricky to work properly with steam and generally require substantial pitch to allow the water to drain. If you post pictures of both ends of the radiator with the end covers removed and one with a level on top some people here can offer suggestions.
