Spring is in the air and that means it’s time to schedule an annual cleaning for your facility’s fire tube or cast iron boiler. Keeping on top of maintenance each year ensures that your boiler is running properly and safely. When your boiler is running efficiently, it also means you are saving money and have less emissions.

Wilkinson Service Technicians follow the proper procedures to get your boiler running like new. On oil fired cast iron or fire tube boilers, we brush and vacuum the tubes to remove any soot. When there is build up between the sections or on the tubes, it lessens the ability for the boiler to exchange heat and therefore uses more energy. Gas fired cast iron or fire tube boilers generally only accumulate a “dusting” as a byproduct of combustion, however these boilers must also be cleaned and maintained. Gas fired condensing boilers require an annual overhaul as well. Just as all types of cars and trucks require tune ups and oil changes, we can help maintain all types of commercial boilers.

Oil burner maintenance includes:

  • Replacing the electrodes
  • Replacing the nozzle(s)
  • Cleaning the diffuser
  • Cleaning the scanner face
  • Cleaning out the oil pump filter
  • Replacing the main oil line filter
  • Testing oil pump suction

The electrode should also be replaced annually for gas burners.

Regardless of fuel, we also clean the water sides to remove any potential scale build up and/or sludge. There are a lot of impurities in water, thus scale and sludge can build up if the water is not properly treated or blown down. In addition, the accumulation of material on the exterior boiler tubes can lead to overheating and premature failure.

Throughout the maintenance appointment, our service technicians will examine all aspects of your boiler. Any issues will be dealt with quickly and capably. Once the cleaning is complete, we will test and tune your boiler. We will get you ready for the fall and ensure your boiler is running at peak efficiency.
