AFUE and Real Boiler Efficiency | Annual Fuel Utilization Efficiency

AFUE much more closely represents peak efficiency, and the energy wasted when the boiler shuts off really cuts down the annual efficiency. Comparing the 83.5% AFUE tankless coil boiler at right, System 2000 will cut fuel bills by over 43%…although there is only a 4% difference in AFUE ratings. This means the tankless coil boiler will burn 77%

Scaling in boilers - Lenntech

Iron deposits in boilers are most often magnetic. They are soluble in hot acid giving a dark brown coloured solution. If unchecked, scaling causes progressive lowering of the boiler efficiency by heat retardation, acting as an insulator.
