Maximizing Small-Boiler Efficiency | HPAC Engineering

Combustion efficiency is a simple (and occasionally misleading) measure of a boiler's heating efficiency. It is equal to 100 percent of efficiency minus the percentage of heat lost up the vent, which is called "flue loss." The thermal efficiency of a furnace or boiler is equal to the combustion efficiency minus the jacket loss.
