BTU output for steam boiler
My radiators E.D.R.is 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
