Where can I find information how to calculate how many BTU 1 rib of cast radiator output.

    Depends on the \"rib\"

    which is known as a "section". There are many different types- can you post some pictures here?

    Also depends on whether this is a steam or hot-water system.

    Radiator is water radiant radiator (24" high and 6" deep)

    EDR

    You could calculate 5 sq ft per section (conservatively)multiply that by 180 for water and for steam use 240 x 5 x # of sections, some swag involved in this equation

    Don't you need to know the temp at which the water will be circulating before you try to determine the potential output of a radiating body? For steam you always assume it is 212 or a little over but water is widely variable as to the temp used when it circulates.

    The sq.footage(capacity of the rads output) should be known, then Yuri can calculate the water temperature it needs to satisfy the room(its going in) H/L requirement. There are tables for this too. He may be able to use a smaller, or larger rad, at this water temperature to meet the demand, and maintain continuity of the circuit, but the EDR must be known first.
    Hopefully he did his homework, to match-it with any other rads(if any) on this circuit! :-)
