IM looking for the EDR of this radiator. I,ve looked in Dans E.D.R. 'Every Darn Radiator', without any luck. The radiator pictured is on a one pipe steam system. 20" high X 5" deep with 14 - 2" wide sections, for a O.A. length of 28". Any help is really appreciated.

    31.5 EDR….U S Boiler calls it a radiant radiator…Some call it a sunrad….In the recessed install such as yours you can subtract 10 percent from 31.5 that would be total EDR for a one pipe steam system

    The subtraction is for output not for total EDR load…I was not sure why you asked for it so I just thought I would clarify that….Sorry If I confused matters..

    You can use the ratings for SunRad radiators. 2.25 ft2 per section.

    Hatterasguy ; Radiator is cast iron (not a convector). ja: Thanks for EDR data - looking for EDR on a stand alone unit - good to know derating of (10%) as a wall unit. star: Thanks for the SunRad input - that fits well with what a contractor told me from his experience. cdm

    Isn't that essentially this?

    As I understand it, it provides both convection and radiant heat.
