Pros and Cons of Kerosene Heaters

It’s a naturally portable, Kerosene-fueled, unvented space heater. 

It’s the primary source of heat in most countries. However, in the United States, it’s considered an emergency heat during a power outage

Ideally, power outages inevitably hit every winter. Many homeowners find themselves without a source of heat, which is why investing in this heater is a good idea.

Kerosene, propane, and natural gas heaters are usually the best options during power outages. 

Although saving energy with kerosene heaters may seem predictable, questions about health and safety haven’t been settled to many people’s satisfaction. 

Before purchasing a kerosene heater, consider making safety a priority. Further, check for protection grills and fuel gauge to prevent burns or to overfill.

If you face any problems using a kerosene heater, always ensure to follow the guidelines provided by the manufacturer.


  • Portable
  • No chimney required
  • Minimal maintenance
  • High combustion efficiency
  • Low initial investment


  • Risk of burns from hot surfaces
  • Some areas restrict sale or use

Propane vs. Kerosene Garage Heater

Working in your garage during the colder months for hours could be devastating, and kerosene and propane heaters may help keep you warm. While they come in diverse sizes and shapes, they offer dozens of portable heating options.

Kerosene or propane heaters are affordable, reasonably standard products that can be easily chosen to accommodate the space you need to warm. 

Although they are both perfect for indoor use, we’ll start by discussing what makes them different. 

Propane heaters for garage are majorly considered as the cleanest, most eco-friendly way to keep your garage warm during winter.

Although it’s slightly costly than Kerosene, it’s widely available. Kerosene heaters, on the other hand, are in high demand because of their incredible heat output. They are designed to give out more heat than most space heaters.

In a nutshell, if you’re more conscious of how much you spend on fuel, consider going for propane since it’s more efficient. Besides, it burns so cleanly, lasts longer, and doesn’t create any smoke.

Nonetheless, a portable kerosene heater will bring your garage to temperature in a flash. With Kerosene, your garage will warm up more quickly, and you’ll heat square footage with a single unit.

Are Kerosene Heaters Safe to Use in a Garage?

When it comes to using a kerosene heater indoors in your garage, your safety majorly depends on how you maintain, operate, and locate it. Always take time to know and understand the precautions outlined in the user manual. In case you don’t understand some aspects of safe operation, feel free to ask the dealer.

Can you Leave a Kerosene Heater On All Night?

It’s never appropriate to leave even the most efficient kerosene heater run all night. Always ensure you turn it off when going to bed. Keep an eye on the tank as you refill it to avoid spillage, which may cause a fire. If you have children and pets, it’s wise to position the heater where it’s not easily reachable by them.

Do I need to Vent a Kerosene Heater?

Ventilation is of great importance when it comes to using a kerosene heater. A Kerosene heater can emit pollutants like carbon monoxide, nitrogen dioxide, or Sulphur dioxide, creating a risk to the elderly, pregnant women, and young children. Consider using a modern vented kerosene heater as a safety measure.

Here is how to vent a garage heater through the wall

Do Kerosene Heaters Give Off Fumes?

Sure, mainly when operated inappropriately. It draws in air and releases heat from the internal combustion of Kerosene. Although the combustion process may be efficient, certain toxic fumes such as Sulphur, carbon, and nitrogen oxides are released.

The building’s characteristics, the room’s size, and the type of heater all contribute to the potential build-up of toxic fumes. Ensure you operate your kerosene heater in a well-ventilated room. You can as well keep your heater clean and install smoke detectors for maximum protection.

 How Long will a Gallon of Kerosene Burn?

Well, with a portable kerosene heater, you’re more likely to make frequent trips to a kerosene dealer. One large convective heater operating 15 hours a day needs up to 14 gallons of fuel a week. 

This means that it takes over 8 hours on a full tank to burn evenly while the wick takes forever before getting the carbon spots on top.

For precautionary measures, never mix gasoline and Kerosene, don’t even attempt to use a gasoline can as a substitute for a kerosene container. A garage is preferable to the house. Resist the temptation of refueling a hot kerosene heater in a warm house.

Also, ensure you follow the siphon pump instructions and fill only about 90 percent of the tank. This is essential since cold Kerosene expands in a heater tank as it warms to room temperature and could overflow if there isn’t enough vent.

Can you Use Fuel Oil in a Kerosene Heater?

For standard basics, you must never burn an oil fuel in a kerosene heater. Manufacturers don’t recommend any other fuel to be burned in a kerosene heater other than Kerosene. But it doesn’t necessarily mean that it can’t be done.

Conversely, Kerosene is a light grade of diesel, while heating oil is heavier and less explosive than Kerosene. If burned in a kerosene heater, heating oil smokes up and emits noxious fumes.

Besides, it increases cleaning and maintenance costs since it tends to leave unburned deposits on the wick. Although it may work on a kerosene heater, it hardly seems to be worth the trouble.

That makes this kerosene heater excellent for both one-car and two-car garages because it can heat rooms as large as 380 square feet.

It has a large capacity gallon that can hold up to 1.2 gallons (4.5 liters) of fuel. That should be enough to give you warmth for 12 to 14 hours per fill. 

You can use it for emergencies as well as everyday supplemental heating. Even if you have another heating source, it’s good to have a kerosene heater just in case your primary heat source fails (for instance, if there is a power blackout)

If your garage is larger than 380 square feet, this heater won’t do. Some two-car garages are 20 x 20 feet (400 square feet) and 20 x 22 (440 square feet). This heater is only effective up to an area of 380 square feet.

2. Dura Heat DH2304S 23,800 BTU Indoor Kerosene Heater

No products found.

This heater produces more heat than the Sengoku above (which does 10,000 BTUs). This one provides 23,800 BTUs. It projects heat in a 360-degree radius, so every corner of the room will be heated equally since the heater is distributing heat all around.

Dura Heat DH2304S design considers safety. It’s easy to burn your fingers when you are operating a heater. To protect you from that, the heater’s design features a protective grill that encircles the hot surface areas.

It, however, does not last as long per fill as the Sengoku heater above (which lasts 12 to 14 hours). This one does between 8 and 12 hours per tank of fuel. That’s still a lot of time, though, especially in times of emergency.

One noticeable con is that there is a kerosene odor. The odor is not so extreme that it is overwhelming, but it is still noticeable.


  • Easy assembly
  • High heat output
  • Projects heat in 360 degrees
  • A protective grille ensures you don’t burn your fingers


  • Has a noticeable kerosene odor

Wrap Up

Kerosene heaters play a significant role during power outages. If it’s well-designed, it emits no strong odor or smoke during regular operations.

However, you’re more likely to notice a faint kerosene odor when you enter the house. Misuse of kerosene heaters could replace room oxygen with carbon monoxide, resulting in death by asphyxiation.

Therefore, it’s crucial to have adequate ventilation in your house as a source of fresh air. What’s more, read and understand the user manual and ensure you remember all the safety and operating features. Good luck!
