I'm wondering if this is normal or not. There are a lot of wrapped heating pipes in the basement, all heading off to the various radiators. One of the pipes, which elbows up right above the Oil Tank, has a steam valve right at the joint.
When the heat is on, this valve exhausts steam into the basement. It is about 5 inches below the floor joists, and as you can imagine, the steam is putting quite a lot of moisture both on the joists and floor. More so if it's a cold enough day that the heater is running for a few hours.
This could be quite normal, but it seems to me that this is a potential mold/rot issue. Venting to the outside would be more logical, although then we would have icing issues when it starts to snow, so maybe not. Not sure what other options there are. Also, the smell in the basement when the valve is venting is pretty bad.
