Combustion Air Requirements:The Forgotten Element

Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.

Efficiency Benefits of a Boiler System Upgrade | 2018

Replacing the boiler is the obvious choice; however, it may not be necessary. If the boiler pressure vessel is in good shape, upgrading the burner and controls while adding heat recovery can not only restore a boiler to its original efficiency but probably improve it. To increase efficiency of a boiler system, consider the following upgrades.
