A boiler preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the boiler fails. This page gives the schedule used in the PlantOps360 task library for boiler (small/medium package), which follows common industry practice for general-purpose equipment. It is also searched for as package boiler, fire tube boiler, steam boiler, oil fired boiler.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.

Boiler maintenance frequency and yearly workload
At the estimated times, one boiler needs about 213 hours of preventive maintenance a year. The biggest single job is “Internal inspection, descaling and statutory inspection preparation” at 960 minutes, done annual. Multiply by the number of units you have to see the workload for your plant.
| Frequency | Tasks | Time per round | Hours per year |
|---|---|---|---|
| Daily | 2 | 25 min | 152.1 h |
| Weekly | 2 | 35 min | 30.3 h |
| Monthly | 1 | 60 min | 12.0 h |

| Annual | 1 | 960 min | 16.0 h |
What goes wrong on a boiler without preventive maintenance
- Low water level, the most dangerous fault in a steam boiler
- Scale and deposits from poor feed water
- Burner and combustion faults
- Safety valves that stick or lift at the wrong pressure
What to watch between services
- Water level gauge, pressure and blowdown
- Flue gas temperature
- Feed water TDS and hardness
Safety and statutory notes for boiler maintenance
Boilers are regulated. Inspection and certification by the inspecting authority, and the rules for attendants and repairs, apply. Keep the certificate with the boiler record.
