I have already figured out my total EDR for the most part but am curious if anyone has actual published info on these Kohler radiators.  I have various sizes from 7 sections to 20 sections as well as slightly different hights.  Most are between 20 and 22 inches high.  They are around 8 inches deep.



I'm more curious about their age at this point than the EDR however both would be of interest to me.  The town says this house was built in 1920 but the radiators seem too new for that.
Single pipe quasi-vapor system. Typical operating pressure 0.14 - 0.43 oz. EcoSteam ES-20 Advanced Control for Residential Steam boilers. Rectorseal Steamaster water treatment

    Here is a Generic EDR Guide

    This comes from an old publication of the ASHRA Guide Book.  Use Table 2 as you have Large Tube radiators.
