Ratings may be expressed in the following units

steam boilers require greater heat input from a cold start than water boilers before heat flows to the system, steam net ratings for automatic fired boilers are slightly lower in relation to gross output than water net ratings. MBH Net Water = Gross Output - Water (MBH) / 1.15 MBH Net Steam = Gross Output - Steam (MBH) / X.
