Best Kerosene Heaters of 2023

Have you ever been told you’re burning the midnight oil? Before electric lights became common, oil lamps were really the only option for illumination after dark—but these weren’t terribly efficient since they produced only weak limited light. That all changed circa 1846 when Canadian geologist Abraham Gesner began experimenting with coal. He figured out that solid coal could be distilled into a liquid lamp fuel that burns much more brightly than regular oil. And so kerosene was born. Gesner patented the distillation process and sold it. Kerosene would eventually become the fuel used most widely to light North American homes in the 1860s—and enjoyed that status until electricity generation. The kerosene heater, though, never went away.

In many places, indoor kerosene heaters remain popular for routine heating in homes. People who usually rely on electricity or natural gas for indoor heat benefit from portable heaters as supplementary or backup heating. Kerosene heaters will warm a home during a power outage or blackout. They’ll also heat a zone that doesn’t get much heat from a central heating unit, heat spaces like garages or workshops that aren’t connected to the main heating grid, and provide heat during an outdoor activity (think camping or fieldwork) where a small heater can take the chill off.

The best kerosene heater now does the same thing kerosene did way back when: It provides reliable, efficient fuel to make people’s lives more comfortable.

This accessory converts a kerosene camp stove (or any stove) into a safe, efficient mini kerosene heater.

What to Consider When Choosing a Kerosene Heater

Convection or Radiant Heat

There are two basic ways that kerosene heaters pump at that sweet heat, and the most energy efficient heaters will match their function to the user’s needs.

Radiant kerosene heaters heat objects in front of them (think of a radiator in a home). For this reason, these are usually better for smaller areas or applications where you don’t need 360-degree coverage.

Convection kerosene heaters heat the air. These are best for large areas or for placing in a central spot and heating multiple rooms.

BTUs

BTUs are British thermal units or the amount of energy required to raise one pound of water one degree Fahrenheit. If you’re thinking this is weird because the Brits use neither pounds nor Fahrenheit to measure things, you’re not alone. Apparently, the BTU was designated in 1876 way before Great Britain adopted the metric system. (Whew, glad we cleared that up.)

The BTUs listed on a kerosene heater will tell you how much energy the heater uses to produce heat and corresponds to the size of the space that will be heated. Most kerosene heaters will convert BTUs to square footage on the packaging, but if not, the math is easy. Multiply the square footage by 20 to figure out how many BTUs you need to heat the space. For example, if you’re heating 500 square feet, you’ll need a 10,000 BTU space heater. At the other end of the spectrum, if you’re tasked with heating a 6,000 square foot worksite, the best kerosene heater for the job will be rated at a whopping 120,000 BTU.

Fuel Type

There are safety considerations when it comes to filling a kerosene heater. It’s important to use pure 1-K grade kerosene, which will be colorless. Impurities like bits of gasoline change the color of kerosene, pose a fire risk and release pollutants into the air. 

When filling the kerosene heater, always take it outside for maximum ventilation. Wait until the unit is cool to touch and only fill to the fill mark. This leaves room in the tank for the fuel to expand without spilling over.

Some kerosene heaters are designed for use with either kerosene or diesel fuel. That can be convenient if you don’t have access to a kerosene retailer or are bringing the heater to an area and don’t want to transport kerosene with you.

Capacity

It’s always important to follow the manufacturer’s guidelines and use common sense safety precautions when using a space heater. This is especially true for indoor kerosene heaters.

First, remember that burning kerosene will give off a small amount of carbon monoxide, so it’s important to only use kerosene heaters in well-ventilated places. Some units will have a carbon monoxide detector built into the heater, but the best practice is to install a separate carbon monoxide detector when using a kerosene heater indoors. (It’s always a good idea to install a carbon monoxide detector, so this is a great reason to make sure yours is functioning properly, or upgrade!)

Make sure the indoor kerosene heater has a removable fuel tank. This makes it simple to lift out the fuel canister for filling outside or in a garage.

When the indoor kerosene heater is in use, place it carefully to ensure that walkways, hallways, and entrances are kept clear. Never place a heater close to furniture, curtains, or textiles.

Indoor kerosene heaters often have specialized safety features for maximum security. Look for a unit with push-button ignition, a one-touch shut-off, and automatic shut-off if the unit tips over or overheats.

When Gesner invented kerosene, he was taken with how much more brightly the fuel burned compared with regular lamp oil. Today, kerosene heaters leverage that bright burn to heat a wide variety of spaces: indoors and outdoors, from small rooms to massive warehouses and job sites. By paying careful attention to the BTU rating and specific features, it’s simple to find the best kerosene heater for any application.
