In this weeks video, I discuss troubleshooting steam by understanding how it breathes. I had such a hard time with his as I was used to hydronic and air systems that dont breathe.

    It is useful to think about each radiator as a lung that must exhale (get rid of air) before it fills with hot steam, and then when it cools it creates a vacuum that draws the air in.

    I have a radiator that is often, but not always cold. Should I check the little valve that releases the air? Maybe replace it?

    You could check it by listening to it from a cold start. Sometimes they get plugged and should be replaced
