Very Old Two Pipe Radiator

Long Beach Ed

Anyone know how the base of this radiator is internally arranged and how the steam circulates through it? We'd like to use this as a single pipe radiator, with the return plugged. That's an 1-1/4" supply and 1" return.

It may be a pre-1890 Bundy; where later ones just had a single internal baffle.

The heating load is minimal, so condensate load should be less than its design. If it doesn't work out, we'd add a return with a condensate loop…

One section was tapped in later years for a vent. Check out the original vent standpipe on the end. Thanks for all your help!

Is there a name on the base? If it's a Bundy, it would be "A.A. Griffing".

Long Beach Ed

Nope. No "AA Griffing" or anything anywhere.

No particular reason why that won't work, at least after a fashion, as a single pipe radiator. However, it will probably work better — indeed remarkably well! — if you pipe it as though it were a two pipe radiator. Inlet on one side and a return on the other. With a twist. Is there any way at your proposed location that you can create a water seal on the "outlet" side? If so, and you put an air vent on that outlet pipe, it will function exactly as a two pipe would…

It pays to wander off The Wall.

Ed...I have two I installed in my house. The long one in the parlor is piped, Two-pipe. The smaller of the two is in the kitchen and works great on one-pipe. Mad Dog
