BTU size of new natural gas boiler

Don10000 Member Posts: 21
Looking for the correct BTU size for a new Gas boiler.
Converting from oil to natural gas boiler – Steam heat.
There are a total of 12 copper convector radiators. Single pipe steam radiators.
I measured the length of each of the 12 convector radiators.
The lengths are 57, 37, 17, 30, 29, 33, 45, 38, 57, 57, 46, 17 = a total of 463 inches of length.
Each copper convector is 2” in height and 5.75” in depth.
9 convectors have 3 copper tubes running lengthwise
3 convectors have 4 copper tubes running lengthwise

Thank You!

    Your going to have to try and get the EDR ratings off all those convectors. Any names or markings on them? Or on any of the enclosures?
