    I just earned my GED and am looking for a apprenticeship with one of these steam gurus on this site!

    At that angle it's hard to tell how tall it is. If those wall tiles are 12" high, they'd be 9-Bs instead of 7-Bs. In that case the EDR would be 18. @keith123, can you measure the height of the radiator?

    Actually, @luketheplumber, you're probably right. That TP holder is probably 4", high, so that would make the tiles 8" high.

    I have three all together. All are 21” wide. Heights are 25 x 2 and one at 38”

    Do you have a picture of the 38" tall one? American didn't make the wall radiator in that size, so it must be a different make.

    American made five different units that could be put together to build larger radiators. This is a summary of the units' sizes and EDR values:

          height   width    EDR
    5-A   13⁵/₁₆   16⅝      5
    7-A   13⁵/₁₆   21⅞      7
    7-B   21⅞      13⁵/₁₆   7
    9-A   13⁵/₁₆   29¹/₁₆   9
    9-B   29¹/₁₆   13⁵/₁₆   9

    The radiator you pictured looks like it's made up of two 7-B units.
