In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
We've been working for this family since before we started All Steamed Up, Inc.- they were customers of my former company. This is the house where the family patriarch lives- he is 97 years young, and the house is 90. The Vapor system was originally Hoffman, possibly with a Differential Loop, but was updated with Illinois F&T traps, air trap and return trap, and Honeywell zone valves. We believe that was done sometime in the 1940s, same time they installed radiation in the converted side porch. We've seen one other Hoffman-to-Illinois system in Baltimore so far, and I suspect there are others.
The boiler was installed in the 1980s, with the usual incompetent piping job. The basement has severe water infiltration issues, which finally rusted out the wet return. But the boiler didn't rot out in a section- one of the section seals near the boiler steam outlet failed. It still kept the house warm thru last season, though.
