old Arco Cast Iron convector

Options
to Dan's book "E.D.R.", but realized my stuff was older (1939) and had some sizes E.D.R. didn't. So here it is. It's a pretty hefty download- allow ample time if you have dial-up.

Dan, as always, feel free to add this to the Library, the second edition of E.D.R. or both.

    I'm wondering if anyone out there happens to be blessed with old ratings information on the Arco Cast Iron convector? Have viewed what is available here in the Library, and the information Dan has in the archives does not provide ratings on these old timers. Anyone?? I'v got a number of 3 intermediate, 4 intermediate and 5 intermediate convectors. Thank you in advance for any help.

    I have them

    if you can post the length, depth and height of each convector cabinet, the rest should be easy.

    Is this a steam or hot-water system?

    Arco convectors

    Steam job - 2-pipe. V. large Church - I took them off while the Engineer wrote the numbers down. He has not given me any dimension data yet. I remember that Cabinets were all 38" inch high. The finned sections were sometimes 3, 4 and 5 across (front to back) and differing lengths (left to right) - Lots of them ..... don't wish to impose on your time ..... Any chance you could scan the tables and email them to me? I can take it from there.

    Ahhh, so you're with Burnham!

    Going to install a row of Mega-Steam boilers in there? ;-)

    ARCO cast iron convectors

    No room for that many MegaSteams (or MPO's) ........... but converting a heating system that is one part steam/one part forced hot water to all hot water. Should introduce some nice savings in the long run on this one. Took out the old in-ground oil tank and just operate on Natural Gas.

    Thanks again,

    I wouldn't convert the steam

    You stand a good chance of some rather bad leaks, since hot-water runs at least 10 times the pressure of steam. I know a church that was badly damaged this way. This is one reason my company does not recommend or perform such a conversion, and will not work on a system someone else has converted. We don't need the liability.

    A better course of action would be to install two boilers- one steam, one hot-water.
