      Boiler Efficiency - Engineering ToolBox

      Boiler Efficiency related to the boilers energy output to the boilers energy input can be expressed as: Boiler efficiency (%) = 100 (heat exported by the fluid (water, steam ..) / heat provided by the fuel) (1) Heat Exported from the Boiler to the Fluid. If a fluid like water is used to transfer heat from the boiler - the heat transfer can be expressed as:

      So, for a boiler that produces 210 kW (or 700,000 BTU/h) output for each 300 kW (or 1,000,000 BTU/h) heat-equivalent input, its thermal efficiency is 210/300 = 0.70, or 70%. This means that 30% of the energy is lost to the environment. An electric resistance heater has a thermal efficiency close to 100%.
