What is a potential consequence of not replacing the oil burner nozzle annually?

Higher energy efficiency
Increased risk of fire
Decreased heating costs
Improved system longevity

The correct answer is: Increased risk of fire

Not replacing the oil burner nozzle annually can lead to an increased risk of fire due to the nozzle's crucial role in atomizing the oil for combustion. Over time, the nozzle can become clogged or damaged, which disrupts the proper spray pattern and fuel delivery. This disruption can cause incomplete combustion, leading to the accumulation of unburned fuel in the combustion chamber. If unburned fuel ignites suddenly, it can create a dangerous situation, including a potential fire hazard. Regular maintenance, including the timely replacement of the nozzle, ensures that the burner operates safely and efficiently, reducing the risk of such incidents. This highlights the importance of maintenance practices in promoting safety and functionality in oil heating systems.
