Moving a radiator in two pipe system

JoeChan

We are planning to renovate the kitchen and first floor bathroom. One of the options brought up by the architect is to move the radiator in the bathroom to a different location (90deg, 3ft away). We have an unusual two pipe system with a Hoffman differential loop and runs on only at 6oz of pressure. I'm deadly afraid of changing it, partly because it is two pipes, and partly because moving it will shorten the run of the pipes by quite a lot, and it is near a fairly complicated portion of the piping (there is a three way split just upstream, so potentially affecting the two radiators upstairs). Are my fears unfounded? I've been having a great deal of trouble finding a capable heating guy in Boston with enough experience to deal with this type of system.

Shouldn't be a problem to move it.

The Hoffman Data Book is in Dan's library section on this site so you can do more homework on your system..keep looking for a steam guy..i'm sure there are tons of them in Boston..

Your's is not a complex system

In fact it is too simple which is where I think people have issues.

Charles is right -- the Hoffman system is really simple.



Hopefully you can find a steam guy.  If not, hopefully you can find a plumber who can actually work with threaded pipe.  Figure out where you want the radiator to be.  Figure out the collection of elbows and mipples and pipe to go from where you want to hook up to the existing supply and return lines.  Drill any necessary holes.  Assemble.  That's it.  The only thing to watch is to make absolutely sure that both the new supply and the new return are pitched to drain back to the steam main and the return, respectively.



You will probably find that there are no convenient unions to undo the existing piping, except for the unions on the radiator fittings themselves.  This is not cause for alarm; just be gentle (or as gentle as you can be!).



Or get in touch with Charles.  He's a nice guy and might do it for you!

Thanks all for the advice

I'll get back to the architect and see how it all works into the plans!
