Hutchison System

I have worked on dozens of Hutchison Vapor Systems over the years. They were prevalent here in the DC metro area.

This is the first one I have seen with the receiver still in place. It is piped wrong (copper). It is also too low. It should be at the water line according to old drawings.

I do not know the inner workings of this receiver but I imagine it operates more like a differential loop than an alternating receiver. Maybe Frank can dig into his library for more info?

This one is located in downtown Herndon, VA. It is not our job. I am helping a contractor friend who is replacing the boiler.

    Here is the old stub where the dry return vented into the chimney.

    That’s awesome.

    I don’t think I’ve ever worked on any steam in the Herndon area.

    Nice find...where do you source the black copper...lol?
    Not a bad paint job on copper.

    There was an error rendering this rich post.

    According to Mike's link, that receiver was part of the damper-regulating mechanism.

    Does look like it -- a number of vapour systems (Hoffman Equipped did, for instance) either had integral damper controls, or could add them. Early modulating boilers... :)
