Q1: What is the boiler efficiency?

Apr 14, 2014 · Overall efficiency: "Gross energy output divided by energy input." Overall efficiency, also known as fuel-to-steam efficiency or thermal efficiency, is the combustion efficiency minus the heat lost due to convection and radiation. Seasonal efficiency or AFUE: "Actual operating efficiency that the boiler will achieve during the heating season at various loads." Combustion and overall efficiency refer to …
