    Arco Model Type K heating system

    Does any one have anymore info on Arco Type K heating systems? I saw it in the 1936 issue of A.S.H.V.E. Also in the "Lost Art Companion" Thanks in advance!

    Ross i have worked on a few arco k steam systems a few very important things are low pressure in ounces like 12 ounce max pressure and make sure that the cross over traps are properly working other wise there are distrubition promblem and that the wet returns are checked to ensure that there not plugged after many years of work ,in replacement of original boiler water levels should always be replicated or a false water line installed to keep those drips and gravity wet returns below the water line ,the worst thing that can be done to any vapor system is removing the gravity returns and putting in condensate return pumps and last but not least make sure that your steam mains are properly insulated and that all near boiler piping meets or exceeds boiler manafactures specs and that the main air elimators are working properly .peace and good luck clammy

    What Gerry said

    he apparently has been getting home earlier than we have lately ;-)

    It's Orifice Vapor, basically.

    Type K

    I just thought maybe there was more information available on it. Near boiler piping, etc. Thanks. BTW Frank, I was looking at a one pipe sytem last week that had # 40 Hoffmans for main vents on the dry returns. Another contractor had not did so well on the near boiler piping, and it doesn't look like he changed one vent in the entire house. Had the typical " Should we scrap our steam system?" phone call from the lady of the house. Sometimes, it's kind of a shame that is a "lost art". There are so many "hacks" out there that just don't care about these systems.
