What is the main consequence of insufficient preheating of the oil?

Higher flow rate
Increased efficiency
Difficulties in pumping and atomizing the oil
Decreased oil pressure

The correct answer is: Difficulties in pumping and atomizing the oil

Insufficient preheating of oil significantly impacts its viscosity, making it thicker and more difficult to pump. When oil is not adequately preheated, it does not atomize properly in the burner. Atomization is crucial for efficient combustion, as it allows the oil to mix with air effectively. If the oil does not atomize well, it can lead to incomplete combustion, resulting in increased smoke emissions, potential fouling of the burner, and overall inefficiencies in the heating system. Choosing to preheat oil to the appropriate temperature ensures it flows easily, allowing for a smooth operation of the heating system, reducing maintenance issues and enhancing overall performance.
