Pipe style steam radiators

BerkshireDan

Hello all. I'm looking for output charts for some very old steam radiators from the 1800's. These are the old pipe style which have vertical pipes running up and down. Dan H. has a picture of these on the bottom left cover of his Lost Art Of Steam Heating book but I don't see any charts inside. Any help is greatly appreciated ! Have a great day.

pipe style radiators, ancient

I always count them as 1 square foot EDR per tube.  If they're nestled into a deep cluster, I derate by about 10% on a large job and if they're wide with only, say two tubes deep, I add maybe 10% to the EDR. 



The correction for effective EDR is not my idea.  I picked it up from a Warren Webster book on steam engineering.  They have an interesting little section on how the style, height and number of columns or tubes affects the "effective EDR."  Gotta find the link.
