Kerosene heaters have a very high energy efficiency, and blowers help by improving their heat distribution and air circulation for the whole room. Thus, for kerosene heaters with blowers, rooms heat up faster than those without.
Kerosene heaters are portable and cost-effective appliances for indoor use. The two types of kerosene heaters are convection and radiant heaters. The radiant heaters produce less than 10,000 British thermal units with heat projected in one direction, while convection heaters produce over 22,000 BTUs using omnidirectional heat distribution. Although kerosene heaters provide instant directional heat without electricity, they pose safety hazards such as dangerous soot and carbon monoxide, and the risk of a fire with contaminated fuel.
