Which of the following is a typical maintenance task for a boiler?

Inspecting and cleaning the heat exchange surfaces is a fundamental maintenance task for a boiler. This process ensures the efficient operation of the boiler by removing any scale, soot, or deposits that can insulate the heat transfer surfaces. Clean heat exchange surfaces allow for improved heat transfer, resulting in better fuel efficiency and reduced energy costs. Regular maintenance, including this task, can also prolong the lifespan of the boiler and help prevent issues that could lead to malfunctions or breakdowns.

While replacing the fuel source, increasing steam output, and installing a new venting system may be necessary at certain times, they are not routine maintenance tasks. Rather, they tend to be part of system modifications or upgrades aimed at addressing specific operational needs or regulatory requirements. Regular inspections and cleaning, however, are essential to keeping the boiler in good working condition.
