Has anyone ever seen steam heat radiation done like this? These manifold and tube distributors run around the perimeter of an old mill building - some on the walls, some on the ceiling. I would love to see a btu output chart for them - manifold says they are Crane.......

    What

    No picture, I have to say that does sound like a steam system.

    Neat!

    I have seen those -- in an old mill building in a nearby town.  Work like a charm, except that the expansion roller supports are frozen on some of them so they have some rather impressive expansion noises.



    Hear output charts?  Haven't a clue -- but they are pretty doggone simple, so I would think you could awfully close -- within a few percent, by simply measuring them up and calculating the actual surface area.  It's a bit tedious, but not that hard.  Then take your total square feet and multiply by our old familiar 240 and there you are in BTUh.

    Radiant Steam Heat

    And one shouldn't underestimate how effective they are. Aside of the radiant heat emitted anywhere in direct view of the pipes, they also place a cushion of warm air at the ceiling which radically changes the mean radiant temperature of the ceiling, which can be quite cold on a top floor of those buildings. If suspended about 10 feet from factory windows and used alone without any perimeter radiators, the downward air current created by the windows pulls warm air from across the ceiling, indirectly tempering the chill of those windows and somewhat increasing the pipe coil's output due to increased "sideways" convection.



    A very fine heat source.
