Changing the wick in a kerosene heater is a simple but important task that should be performed regularly to ensure the safe and efficient operation of the heater. A worn-out or damaged wick can lead to poor combustion, which can produce harmful fumes and soot. It can also cause the heater to overheat, which can be a fire hazard.
The frequency with which you need to change the wick will vary depending on the type of kerosene heater you have and how often you use it. However, most manufacturers recommend changing the wick every one to two months. If you notice that the flame is burning yellow or orange, or if the heater is producing smoke or soot, it is time to change the wick.
