    Not a fan of "Port"... I prefer Merlot.

    Regarding the top rad picture, I would use the standard chart for that
    The bottom picture will need someone else to look that up. I'm not sure if it is in the "EDR" book available in the store on this Website.

    Here is a link to the "Standard Radiator Sizing Chart" published by the Hydronics Institute (div of GAMA) formerly I=B=R.

    After you make that expensive repair and you still have the same problem, What will you check next?

    If I had to guess (because there are no other available resources) I would add about 20% to the 6 column radiator on the chart. (not the "6 tube" on the second chart but the "6 column" on the first chart) The surface area where the spaces would be, that make the columns, is filled in by flattening the metal that would have been the part of the tube "Flattened out". The added 20% would be for the extra fin located in that space. It is not "rocket surgery accurate" but what is in this industry?

    What are the ratings on these floor convectors ?

    That's a McKeesport radiator. You must live near Pittsburgh. These aren't listed in the EDR book, but I would refer you to a previous post. https://forum.heatinghelp.com/discussion/159574/mckeesport-radiator-edr-btu-help

    The shorter unit looks similar to National five-tube panel radiation (see p. 157), but the sections are flat on the ends instead of pointed, and the fins are different. Similar idea, though. It might turn out to be a similar design by McKeesport. Look it over and see if you can find a foundry mark on it somewhere.

    This.

    For the shorter radiator- look at the Aetna Flue Window chart on page 57 of "E.D.R.".

    The indirect radiators ("floor convectors") will depend on what model they are.

    Here is a chart that shows the radiation value for flue radiators like the one you have.

    As for the indirect rads, I don’t see any names on them. I figured on hopefully just measuring them
