I am getting some remodelling done, and will have to extend my existing steam system. Several contractors have given me different answers, so I would like to understand the basics to make a decision. The unit is a very old U.S. radiator corp Sun Ray model. I can find the min/max btu input hr ratings, but not the output ratings. Any links /hints on how to go about these calculations?
