Typical boiler efficiency is routinely much lower than AFUE or combustion efficiency, especially for cast iron boilers or boilers with high “mass” and less than 2” of insulation, and for boilers that finish above 120°F when the thermostat is satisfied (AFUE rates boilers with a 120°F return temperature, but they typically run with a 160°F return and 180°F supply). Substantial losses occur because heating a 400 to 600 pound boiler to 180°F may take 8 to 15 minutes just to heat the
Best Gas Boiler. Gas hydronic heating systems usually have an AFUE rating of 82% or better.
