Measure 1.2.1 Test boiler efficiency on a continuing basis.

ECONOMICS

SAVINGS POTENTIAL: 2 to 10 percent of fuel cost, typically. Credit the savings to the specific actions that you take to improve efficiency, such as optimizing the air-fuel ratio, optimizing fuel oil viscosity, etc.

COST: You can purchase a good chemical combustion efficiency test kit that measures oxygen, carbon dioxide, and smoke for less than $500. A chemical carbon monoxide tester costs less than $300. Electronic testers of reasonable quality cost from $1,000 to several thousand dollars. Also, consider the cost of the actions that you take to improve efficiency.

PAYBACK PERIOD: Very short, to several years, depending on the amount of fuel consumed by the boiler and its tendency to lose efficiency.

TRAPS & TRICKS

TRAINING AND ADMINISTRATION: Efficiency testing does not require a high level of skill, but it does require practice and strict adherence to the instructions. If you delegate this responsibility to others, make sure that they are well trained.

SELECTING THE EQUIPMENT: Don’t skimp on the quality of the test equipment. If your budget is limited, get a proven chemical test kit. The quality of electronic test equipment varies. Higher price does not necessarily mean better accuracy. High-quality electronic testers are easy to use and reduce the opportunity for mistakes.

KEEP IT UP: Efficiency testing is easy to forget. Schedule periodic review of testing procedures. Verify that testing is done properly, that results are recorded, and that appropriate action is taken.
