Jul 22, 2004 · The earliest such measure of boiler output, the “nominal or rated boiler horsepower,” was simply based on the area of the boiler's heating surface. Each 10 square feet of surface represented 1 boiler horsepower, so a boiler with 100 square feet of heating surface would be rated at 10 boiler horsepower. Because boilers vary greatly in design and efficiency, this is a very inadequate way of rating them.
