BTU output for steam boiler

cdmcdm Posts: 70Member
My radiators 210 sq.ft. or requiring 50,400 BTUs of Boiler output.  The closest Weil McLean gas fired unit is 47,000 BTUs.  Would I be making a mistake getting a boiler that is 7% smaller than calculated or should I look for another vender to fit the 51,000 BTUs calculated.

thanks cd mulford
