adding steam radiator to an enclosed added room

ryder

Hi,
I have no idea what i am doing but everyone i talked to said this was the place to ask.

I have a burnham Pv84sc-hbun 127 mbh that was oversized for two added rooms for first and second floor. I only did the first floor 18' x 12'x 8'. I have 11 existing radiators, 6 - 3' x 35 Double sec, 5- 20" x 60 Double sec, 1 - 24" x 8 single (4" wide) sec.
The spot for the radiator is 15' from nearest steam pipe. The room is on the first floor. It would be exposed so I guess I would have to actually block it in and insulate.
Is this something that can be done?

First thing to do is to figure out your heat requirement for that room. Then size the radiator to fit. Then run your runout... make sure that existing steam pipe is big enough to handle the load.

Best to get yourself a copy of The Lost Art of Steam Heat -- available on this site -- which has all the tables you need.

Thank you so much. What should I know about hiring someone to make the connections besides references. I want someone who will do he return and connections properly so my heating system won't go crazy.

Thank you so much Erin. I am going nuts trying to figure what size radiator and how to do it.

@ryder - Follow @Jamie Hall's advice to "figure out your heat requirement for that room. Then size the radiator to fit. Then run your runout... make sure that existing steam pipe is big enough to handle the load" and get a copy of We Got Steam Heat. It will give you a better understanding of your heating system.
