Kerosene is a much cheaper fuel source than electricity. If you use a kerosene heater, you’ll likely spend $70 less to operate it during the winter season than electric heaters.
While kerosene units are more efficient than electric models, not all of them are created equal. Some will be feature-packed than others, some will produce more heat than others, and some will be more efficient than others.
If you want to save even more money while heating your home, you must find the most efficient kerosene heater. According to Department of Energy projections, these kerosene units can help you save between $100 to $600 depending on your room’s size and geographic location.
Check out these kerosene heaters and pick one depending on your needs.

Are Kerosene Heaters Efficient?
Kerosene heaters are more efficient than electric space heaters and other types of heaters. Kerosene is cheaper than electricity. You will pay higher amounts for using an electric heater as a supplemental heat source in your house than when using a kerosene heater.
Besides, kerosene heaters tend to have higher heating capacities than electric heaters. The inbuilt fan in kerosene heaters ensures the effective distribution of heat across large indoor and outdoor spaces.
Therefore, the relatively high heating capacity and the low operational and maintenance costs of kerosene heaters make them more efficient than electric heaters.
How Long will a Gallon of Kerosene Burn?
Although kerosene heaters have different sizes of tanks, the larger types can hold 1.2 liters when full. A 1.2-gallon fuel tank can keep a heater running for up to 14 hours.
This means that 1.2 gallons of fuel can be used to provide warmth for 14 hours. Therefore, one gallon of kerosene can keep a heater on for 11.6 hours.
Remember that the rate at which a heater burns fuel depends on the settings. If you keep the heater at a high-temperature setting, then the quality of consumption of fuel will be correspondingly high.
Always use high-quality kerosene for maximum efficiency. Using 1K-grade fuel is more efficient than utilizing lower-grade types that retail at low prices.
Here are small kerosene heaters for maximum efficiency
Is It Safe to Leave a Kerosene Heater On All Night?
It is not safe to leave a kerosene heater on all night. Ideally, do not leave a kerosene heater unattended even during the day. This is because when you use the heaters, you assume a certain degree of risks, including fires, explosions, and even carbon monoxide poisoning.
Although it is possible to take all safety precautions when using a kerosene heater indoors, it always advisable to turn it off at night before going to bed. Failure to do so may expose you and everyone else inside a room to the risks of using kerosene heaters.
Does Kerosene Burn Cleaner than Diesel?
Kerosene burns cleaner than diesel because of its properties. Kerosene is designated as the number 1 fuel because it is lighter than other types, including diesel.
Because of its light nature, kerosene produces much less energy than diesel when burned. A gallon of kerosene produces 135,000 BTUs of energy while that of diesel produces 139,000 BTUs.
Furthermore, kerosene produces less soot and other byproducts of the combustion process, including Sulphur dioxide and carbon monoxide gases than other fuels.
Its chemical composition is less complex than that of other fuels, including diesel. The difference in the weight and level of chemical complexity are the reasons why kerosene burns cleaner than diesel and different types of fuels.
A kerosene heater is an important type of space heaters to include in your winter heating plan. The most efficient kerosene heater will not only reduce your heating bills but also helpful during power outages.
If you use them as per the manufacturer’s guidelines, kerosene heaters are safe and will help keep your home comfortable and your energy costs lower.
