Does anyone know where I can find the EDR ratings for old Recessed Tuttle & Bailey copper steam convector radiators? I’m trying to determine the size of a new gas boiler. Two plumbers gave me their thoughts. One was 90K BTU, the other was 200K BTU.
I also realize I have to consider all piping to get the correct calculations.
Thanks a bunch!

If you can't find the Tuttle & Baily info find the rating of a new similar convector it will be close enough0 -
