Routine cleaning and maintenance of a boiler is essential to keep it functioning well. But the various terms for boiler repairs and equipment can be confusing for non-experts. Use the following term descriptions to guide you as you seek these services.
Boiler Flushing - A process of draining the water from a boiler to remove dirt and other debris. Flushing your boiler can extend the life of the equipment, prevent surging and keep the boiler working efficiently.
Skimming - A maintenance process employed to remove oil slicks and residue from the boiler. A service technician will open a special drain valve to skim the oil. Oil residue can lead to surging and inefficient boiler operation.
Descaling - The cleaning and removal of scale and deposits from the interior parts of the boiler with the use of chemicals. A vacuum system may be employed in the process.
Surging - The action of a boiler when the water level drops up and down wildly, due to inefficient steam bubble release. A heating repair technician can help troubleshoot and prevent surging issues.
Boiler Tube Overlay - A process of welding and fixing boiler tubes that need repair. This can be a more cost-efficient option over tube replacement.
Boiler Leak Repair - A liquid refractory product that seals holes or cracks in the boiler that are causing leaks. Many repair products allow a homeowner to complete a boiler fix without professional help.
Gaskets - Essential boiler parts that serve various functions in the appliance. Fireside gaskets protect from gases while water-side gaskets seal pressurized water. Door gaskets function to seal the boiler door.
Residential and commercial buildings that use boilers will need to have them cleaned and repaired fairly often. Keeping the equipment clean helps prevent future breakdowns and gives professionals the chance to check for leaks that need to be fixed. Overall maintenance extends the life of residential and industrial boilers by fixing broken parts before they cause extensive damage and keeping the equipment clean of soot.
Some of the boiler repair and maintenance contractors that work in your area might focus on specific types of equipment. They might have lots of experience troubleshooting residential systems. They might not have the same experience though when it comes to looking for gas leaks and broken vacuum parts in industrial systems. It is important to choose a maintenance company that knows how to work on the equipment installed in your home or building.
It is also important to consider which companies have access to the repair parts needed to fix your equipment. If they have the replacement tubing, chambers, and vacuums on hand, then they should be able to repair your system quickly. If they have to order the parts, then it could take several days or weeks before a delivery truck brings the fuel pump or vacuum parts.
Since many combustion, oil, and gas boilers are made of cast iron, the parts can cost quite a bit of money to replace. Some contractors might have used parts that cost less than new ones. Make sure that the parts work properly so that you can heat your building again without any safety risks.
