  • Boiler vs. Furnace Energy Efficiency | Constellation

    Nov 11, 2016 · Energy efficiency in boilers and furnaces is measured the same way — by annual fuel utilization efficiency (AFUE). A unit that has an AFUE of, say 70, converts 70% of its fuel to heat. The other 30% is lost. The federal government dictates that gas- and oil-powered furnaces can't have an AFUE rating of lower than 78%.
