    That can vary widely based on outside temps relative to how high you keep the room temp and how tight the structure is, but in general, a 15 to 20 minute range is pretty normal.

    No one can answer your question. Wouldn't you want the system to have run times of 0 minutes? There needs to be more information.

    How big is the boiler?
    Have you done a heatloss on the building, using the SlantFin free program?
    How quickly does the steam arrive at the radiators, and is it simultaneous for them all?
    There are many things to consider when answering this question.--NBC

    Well the temp is around 30 tonight and I was getting 15-18 min run times with the boiler that hasn't run since 330-400pm. The radiators are getting steam in about 7 min or so. I have a Weil McLain eg 40 steam.

    Is the space comfortable? What's the design temp there?

    It's very comfortable I leave the thermostat set at 70. Don't believe in a set back with steam
