Can someone please help me calculate my edr for steam boiler?
I have 12 cast iron radiators all 23” tall from floor and 6.5” deep. I also have 1 governale cast iron baseboard radiator which is 24” long x 10” high.
All of radiators have 4 tubes. (See attached pics)
2 radiators are 6 sections
2 radiators are 14 sections
6 radiators are 16 sections
1 radiator is 18 sections
1 radiator is 20 sections
1 baseboard governale 24”

I got 450edr but not sure if I did my calc right

    I get 435EDR, not counting the Governale. If you have a chart that shows that to be 15 EDR, your calculation is correct.

    It shows 3.40 sqft per linear ft for baseboard. So must’ve miscalculated somewhere but was close. I just redid calc and got 441.8
    I see peerless has one rated 452sqft is that too oversized?
    Thanks Fred

    That Peerless should be fine.
