overall efficiency of gas boiler

  • Why no 90+% efficiency steam boilers??? — Heating

    You can boost the overall efficiency of a steam boiler into the 90% range by adding a separate heat recovery unit to the flue gas. This will give an overall efficiency corresponding to the reduced exit flue gas temperature and will condense some of the water in the flue gas if the temperature is low enough.
