How do indoor kerosene heaters work?

Indoor kerosene heaters use a simple yet effective mechanism to generate heat and heat your living space. Understanding how these heaters work is essential to their safe and efficient operation. Let us go through the basic mechanics and components of indoor kerosene heaters: Let me explain.

All Parts Of Basic Kerosene Heater

Burner Assembly

At the core of an indoor kerosene heater is the burner assembly. It consists of a fuel tank, a wick, and a burner unit. The fuel tank holds kerosene, which is drawn through the wick to the burner unit.
