Kerosene heaters can also efficiently heat large spaces, including garages, studios, and other areas where you don’t have an electric outlet.

Since you’ll find many options on the market, we have reviewed some of the best kerosene heaters. The most crucial factors to consider before selecting a heater are coverage area and heat output.

You want to make sure the heater can produce enough heat to keep the room at your desired temperature. We’ve gone into more details in the buying guide.

How Much Space will a Kerosene Heater Heat?

Kerosene heaters, like natural gas and propane-burning heaters, can provide adequate warmth in areas that are as large as 4,000 square feet. This heating capacity is higher than that of standard electric space heaters.

Kerosene heaters can warm large areas because they have fans. The fans serve the critical function of spreading the heated air across large areas.

Because of this characteristic, kerosene heaters can be beneficial in heating large outdoor spaces, including garages, small sporting areas, and workstations.

How Big of a Kerosene Heater Do you Need?

The size of a kerosene heater that you need depends on the space that you would like to heat. The number of BTUs that you need to warm any indoor or outdoor space is directly proportional to the size. You will need large amounts of BTUs to heat big garages with kerosene heaters and less BTUs for small indoor spaces.

Kerosene heaters come in different BTUs from 10,000 to 200,000. To select the right size of a heater for your space, first, measure the area in square feet. If your garage measures 20 by 20 feet, then its size will be 400 square feet.

Once you have the area of the space that you would like to heat, multiply the figure by 20. A general rule of thumb is that one requires 20BTUs to heat every square space.

If your garage has 400 square feet, then the total amount of BTUs needed to keep it warm will be 12,000. However, you may have to consider other factors before settling on a kerosene heater’s right size.

If the garage has many open spaces that allow warmed air to escape quickly, you may consider getting a heater with a higher BTU level than 12,000. This capacity will help you address the unique heating requirements of the space.

How Long will a Kerosene Heater Run?

The length of time that a kerosene heater runs depends on the amount of fuel in the tank. A kerosene heater is designed as a highly efficient source of supplemental heating for outdoor and indoor spaces.

The most efficient kerosene heaters are more economical than electric space heaters because the kerosene price is lower than that of electricity. It will cost you less to keep a kerosene heater burning as a source of supplemental heat in your home than using any electric space heater.

The fuel tanks of kerosene heaters that are available on the market are of various sizes. Standard kerosene heaters come with fuel tanks that can hold up to 1.2 gallons or 4.5 liters of kerosene. When such heaters are used to provide warmth with full fuel tanks, they can run for up to 14 hours.

Remember that your kerosene tank’s actual fuel consumption rate depends on the level of heating at which it runs. If you maintain your heater at a high-temperature level, it will consume the kerosene faster than when you keep it at a lower temperature.

Is it OK to Use a Kerosene Heater Indoors?

Kerosene heaters produce different gases, including carbon monoxide, Sulphur dioxide, and nitrogen dioxide. Whereas some of the gases may produce foul smells, some, such as carbon monoxide, are entirely odorless yet very poisonous.

If you use a kerosene heater in the house, you will have to assume the gas risks. Carbon monoxide has been known to cause many deaths due to asphyxiation.

However, when enough amounts of oxygen are supplied, then the production of carbon monoxide subsides. When enough oxygen is provided, the carbon monoxide is quickly converted to the less deadly, carbon dioxide form.

The logic of using a heater that burns kerosene or any other type of hydrocarbon fuel indoors is to ensure that there is enough supply of oxygen. This strategy helps minimize the amount of carbon dioxide produced when the heater burns the fuel.

If you decide to use the quietest kerosene heater indoors, ensure that the room is adequately vented. When there is an adequate supply of oxygen across the room, no carbon monoxide will be produced.

Kerosene Heater Safety

Although it is necessary to observe general safety rules when using any heater, this need becomes urgent when using a kerosene heater.

Having a kerosene heater around your home or anywhere else poses many dangers. The heaters produce a lot of moisture when operating. Excess humidity may cause significant problems if you are using them to provide heat in closed spaces.

Also, using kerosene heaters means that you have to assume the risk of fires. If the heaters are used in environments that are full of flammable vapors, then explosions can occur at any time.

Moreover, the surfaces of the heaters become very hot after a long time. If the surfaces come into contact with highly combustible materials such as papers and fabrics, they may cause fires.

To prevent fire hazards and gas poisoning when using kerosene heaters, follow the following simple safety tips.

  • Use a carbon monoxide detector to help you know when the gas levels get to dangerous levels. This will eliminate the risk of carbon monoxide poisoning when you use the heater in indoor spaces.
  • Keep the wick of the heater wholly immersed in the kerosene. This will ensure that the wick keeps burning and that nasty fumes do not evaporate into the atmosphere. We have a troubleshooting guide for a kerosene heater wick that won’t raise
  • Do not leave the kerosene heater unattended to. Always switch it off if you are leaving the room even for a few minutes.
  • Keep all combustible materials away from the heater. Because the heater’s surface becomes typically quite hot, it can easily ignite any flammable material that comes into contact with it.

How Do you Neutralize the Smell of Kerosene?

The best way is to deal with the causes of the foul odor. Primarily, the bad smell of kerosene occurs when the vapors of the fuel escape into the air. If you can keep the vapors from evaporating into the atmosphere, you would have effectively dealt with kerosene’s foul odors.

One way of doing it is ensuring that the heater always runs at high temperatures. Typically, if the heater runs at low temperatures, the amount of fuel available for burning exceeds the heater’s capacity. This leads to foul odors as the unburnt kerosene escapes into the air.

Another way is to light the heater outside. Before heaters reach the perfect temperature, the ratio of fuel and air is relatively high. Thus, a small amount of kerosene always escapes into the atmosphere when the heater is starting. If you light it from outside, then the bad smells will not permeate the room.
