and it's definitely one of those named above. Did you find the manufacturer's name on it? It's usually cast into the base.

    Radiator EDR & boiler recommendations

    I am trying to calculate for a new boiler and find one of my radiators not listed in the tables in "The Lost Art of Steam Heating." It looks almost identical to the one on the bottom left corner of the book cover - simple vertical tubes in a 2 column arrangement. Any ideas of EDR? It has 18 sections, 2 tubes each and is 38" high.

    Also ... any reccomendations for a new boiler for an 1890s single family home in the Boston area? Anyone every use Slantfin or Triad? Or is something more traditional like Burnham a safer bet?

    Post a digital picture

    of the rad in question and attach it at around 600X400 pixels (size) so it doesn't "blow out" the post.

    Dan's book, "EDR (every darn radiator) has 99% of every standard and obscure radiator from this planet - as well as a few that were from Mars...

    Post the picture, we'll look at Dan's book and let you know what you have.

    That's a Nason radiator

    The ratings are in the Library:

    Nason

    It's an easy one. One linear foot of each pipe equals one square foot EDR.

    Lots of good stuff on this site. It pays to wander off the Wall.
    Retired and loving it.

    Dan's probably right

    also the Bundy and Reed radiators were similar. Sounds to me like you have a bit of a heating museum there! Have you found a manufacturer's name on that old beauty?

    Please post a pic.

    Just recently started using Slantfin

    For gas fired modular steamers. These are the same as the residential steamers. The steam design is basically about 40 years old and incorporates a unique extra wide end section design with internal baffles that really helps dry out the steam. I'd love to cut an end section open to see what it looks like. I recently installed a pair of 190,000 input modules and once the system was cleaned up I was getting no carry over into the header with only 2 1/2 inch inch riser pipng out of the boiler. (The header drip/ equalizer was filling with distilled water, giving the electronic probe low water cut off a false low water signal). If you do your homework and check the steam velocity at that input and pipe size, alot of water should have been coming out of the boiler into the header!

    I like them so far and it is hard to beat their tech support. Oh course, Burnham also has great support and makes a fine home steamer.
