3 Steps in Maintaining Your Commercial Boiler

A boiler is an integral part of many business operations with hundreds of parts dedicated to making it work properly and run smoothly. To keep this essential piece of machinery working correctly and prevent it from becoming a hunk of worthless metal, you can take these three steps.


Although combustion is a given, a complete analysis of the flue gas temperature and smoke test should be done at least once a year in the breeching. Understanding the O2 and CO2 percentage content can be critical in a complete combustion analysis. To establish long lasting and complete combustion, your cleanout plates should also be cleaned with a vacuum and brush but take care that the refractory devices are not damaged.


Maintenance is more than a schedule check on a piece of paper. The boiler needs a dedicated system of checks and balances to keep the unit working properly. Depending on the size and type of machine your company has, a semi-annual service contract may suffice for a thorough review of the entire machine, and then a monthly check of the burner and deaerator parts may be sufficient. Any signs of problems should be dealt with immediately to prevent possible blow back.


It only takes one drip to topple the system, and that is why the occasional leak or drip from the steam or hot water can result in extensive damage over a short period of time. Additionally, the pH in a boiler is an important consideration. If a leak is discovered, the entire pH balance of the water may have become altered and need to be addressed. The oil transmission lines and filters should also be checked for drips.

Maintaining a machine as critical to your company’s operation as your boiler should be a top consideration. Regular service schedules are necessary, and trained individuals with keen eyes for possible problems are best for the job.
