DC Commercial Steam

Dan Foley

Brian, Dragon and Henry spent the last week replacing the steam boiler at The Tiffany, an 8-Story apartment building at 16th and U St. NW.  it was built in 1924 and has a one-pipe steam heating system. 

The old Weil-McLain had rotted out and was leaking flue products into the boiler room.

We went back with a Crown 24 1.8M BTU with a Beckett power gas burner.  We would typically use a Power Flame but 8 week lead time has all but eliminated them from replacement work.  

The system was controlled by a wall mounted thermostat in the second floor hallway.  We replaced that with a tekmar 279 with indoor feedback.

Finished product.  Brian and Henry went back last Saturday to do the start up and dial in the burner.

One of the 4” mains dips under a concrete beam. It was not properly dripped creating horrendous water hammer.  Brian re-piped this drip.  Rather than use an F&T, he went old school and piped a loop seal.  It is now quiet as a church mouse.

Power Flame makes nothing for stock as far as I know. I used to be a rep for them. 6-8 weeks is normal for them. Looks nice. Hopefully boiler water content will not be an issue.

With a vertical building like that it should be fine condensate will come back quickly.

Looks like the old boiler never got cleaned

Great job!

Amazing how people convince themselves they are saving money by deferring maintenance.

This.

Does anyone else think that looks a lot like a Burnham V9-series boiler with a different jacket?

Steamhead, the Crown 24 is the same as the Burnham V-9.  Same casting.

@Dan Foley Thanks so much for your posts and your articles. It was one of the few ways I could learn about steam and hydronic boilers. I don't know alot about welding or commercial installs but why does the drop header have what looks like a welded cap tee instead of just elbow?
