When should the filter in an oil burner be replaced?

The filter in an oil burner should be replaced when it becomes clogged. This is important because a clogged filter can restrict fuel flow to the burner, leading to inefficient operation and potential mechanical issues. Regular monitoring of the filter's condition is essential. If it appears dirty or restricts flow, replacing it ensures that the burner can operate effectively, maintaining proper oil flow and combustion efficiency.

Replacing the filter based on its condition, rather than on a fixed schedule like every month or year, allows for more tailored maintenance. This practice minimizes the risk of operational failures and extends the overall life of the burner system. This focus on condition-based maintenance is essential for ensuring optimal performance in oil burners.
