  • Sizing a Steam Boiler | U.S. Boiler Company

    Dec 05, 2017 · An important note on boiler sizing – all the supply piping in the basement should be insulated with a minimum of 1" of pipe insulation. A better choice would be 1-1/2" or 2" of pipe insulation. An un-insulated steam main is equal to a radiator and must be calculated and added to the above calculation. When operating a steam boiler Learn More
