Understanding Residential Boiler Efficiency Ratings | Weil ...

The minimum AFUE rating requirements for boilers varies based on the type of fuel and the heating medium used. As of September 1, 2012, all boilers manufactured have the following minimum AFUE ratings: 82% for a gas-fired hot water boiler, 80% for a gas-fired steam boiler, 84% for an oil-fired hot water boiler and 82% for an oil-fired steam boiler.

Steam Calculators: Boiler Calculator - US Department of Energy

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
