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.

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...Br. Jamie, osb
