In this video, Dan Holohan explains steam boiler ratings. When you look at a boiler manufacturer’s catalog, you’re going to see Input, D.O.E. Heating Capacity (Gross), and Net. Dan walks you through each of these to help you with steam-boiler replacements. He also provides tips on what to do if a radiator has been removed from the system but the piping is still there.
