    Snoop around off the wall in the Library and Heating museum. There is a lot of good reading on sizing rads with charts. Start here: https://heatinghelp.com/heating-museum/category/radiators
    The second entry should get you started. Do a search for "edr" on The Wall and you'll find additional pdfs referenced.

    I agree with Fred, that radiator is 5 sq ft per section.
