This was an emergency install.... we removed a grossly oversized 175K Btuh boiler and installed a 75K Btuh boiler.... the total measured radiation was 150 sq ft of Edr.... we piped a 2 inch drop header and installed a Vxt 24 automatic feeder. I do not know the exit velocity of a 75k boiler with 2 inch piping .... is it around 15 ft per sec.?
