Steam boiler maintenance checklist

First of all, you need to have a steam boiler maintenance checklist to know what to look for when you want to take care of the system on your own. Every mechanic who knows the way around a steam boiler can easily check each and every item on the list so it’s good to consider having a specialist to check your set up whether an annual or a monthly check. But if you are one of the people who like to do the task all by yourself, you should look for the below-mentioned in your steam boiler:

  • Automatic Water Feeders and Water Boiler Maintenance

Regularly check the automatic water feeders to make sure everything works alright and nothing blocks the process. Water feeders eliminate the need to manually add water to your steam boiler so you need to make sure it works with the same efficiency as always. Also, you should check to ensure the water level reaches the pre-determined level of the steam boiler. If this is overlooked, the boiler leaks and requires replacement. So, it’s better to spend for steam boiler maintenance than to replace the whole thing.


  • Steam Boiler Annual Maintenance Checkup

If your steam boiler has probe style low water cut-offs, it should be flushed at least once a year. Plus, you need to set an appointment with your technician for annual oil burner service and cleaning. Do not try to do this yourself or you might end up hurting yourself or compromise the system. But keep in mind that your boiler’s design might need a quicker flush in the heating season. So ask a technician to know how many times a year your unique steam boiler should be flushed.

  • Weekly Owner Maintenance and Fall Checkups

Yes! Not only does your steam boiler need an annual maintenance checkup, but it also requires weekly maintenance checkup by yourself and a special fall maintenance checkup by a skilled technician. If overlooked, you might end up needing to replace the whole thing.

Make sure you have proper tools for your steam boiler’s weekly maintenance. Boiler bucket, heavy work gloves, screwdriver, etc. And don’t forget to wear the right clothes when you want to work with the boiler. Wear something that dirty boiler mud wouldn’t ruin it and make sure you have the right shoes for this and not your comfy flip flops.

  • Monitor the Steam Boiler

Put monitoring your steam boiler on your weekly routine list. The most important device designed with this purpose in mind is the gauge glass. You can find the gauge glass on the side of your steam boiler which is a glass tube to help you monitor the boiler regularly. You can see the water level with it which enables you to avoid overfilling water and also to ensure it’s not below the desired level.

  • Try to use filtered water

It’s better to fill the boiler with filtered water to keep salt and chlorine out of the steam boiler. These two can ruin the boiler quickly.

  • Deal with surging and skimming

When the boiler is on and the water in it bounces around more than regular, it’s called surging and the main cause for this is dirty water. So again, we see the importance of using filtered or distilled water.

The hardest one: skimming, which means getting the oil and grease out of the boiler. You need to be patient and spend a decent amount of time for correct skimming since it needs to be done slowly so the top layers of water drip into a bucket. You might also need to let some of the water from the bottom level of the boiler flow if possible for heavier unwanted material inside the system clean out. You can also use different chemicals to clean the oil from the steam boiler.

  • Steam Boiler Inspections

The law states that how water boilers must be regularly inspected for safety. It enables you to identify if there are any corrosion or failures around the system.
