I need help calculating the proper size for a replacement steam boiler. The radiator count and calculations from charts yield 1444 sf surface area. The house is about 6000 sf and one-hundred years old. What should the gross output be for an ideal sized boiler? What are the pros and cons of erring on the larger size for a boiler? Thanks for anyone's help.
