Boiler Ratings Explained

When you look in a boiler manufacturer's catalog you'll see that there are several types of ratings for each boiler. There's the Input rating, the Gross Output rating (which some call the D.O.E. Heating Capacity) and then there's the Net Output rating.

Ratings may be expressed in the following units

Gross Rating – The full output of a boiler actually available to the heating or process system at the outlet nozzle. Net Ratings – The net connected design load that can be supplied with heat by a boiler of given output, allowing for normal system piping losses and pickup from a cold start. Since
