Boiler Efficiency | CleanBoiler.org

A realistic excess air level for a boiler in operation is 15% if an appropriate safety factor is to be maintained. When reviewing an efficiency guarantee or calculation, check the excess air levels. If 15% excess air is being used to calculate the efficiency, the burner should be of a very high quality design with repeatable damper and linkage features.
