Kerosene heaters are a popular choice for those seeking an affordable heating solution, especially during power outages or in locations with poor insulation. However, the challenge of sourcing kerosene fuel has led some to consider using diesel fuel as a substitute. While it is possible to burn diesel in certain kerosene heaters, it is not recommended as a long-term solution due to the potential for increased smoke, soot, and carbon monoxide emissions, as well as reduced efficiency and unpleasant fumes.

What You'll Learn
Kerosene heaters are illegal in some places, like Massachusetts
Kerosene heaters are illegal in some places, including Massachusetts. A local fire department in Massachusetts has warned residents not to use kerosene heaters in their homes, as they are a fire hazard. The state fire marshal's office has also reminded residents that kerosene heaters are not allowed in Massachusetts, even though they can be legally purchased in neighbouring states.
Using a kerosene heater in Massachusetts can result in a fine of up to $100 per day. This law applies to "space heaters", including portable space heaters, parlor heaters, cabinet heaters, and room heaters. It also includes any similar heater with a barometric-fed fuel control and its fuel supply tank located less than 42 inches from the centre of the burner.
The law is in place due to safety concerns. Kerosene heaters can be dangerous if not used correctly, and there are safer alternatives available, such as electric heaters with safety features like an anti-tip automatic shut-off mechanism.
While kerosene heaters may be illegal in some places, it is still possible to purchase them in other states. Some people may be tempted to use diesel fuel in their kerosene heaters as it is cheaper and more readily available. However, this is not recommended as it can cause a lot of smoke and soot, and may not be safe.
If you are considering using a kerosene heater or alternative fuel, it is important to check the local laws and regulations to ensure you are complying with safety standards.

Diesel can be used as a substitute for kerosene if it has an additive
While kerosene is recommended for use in heaters, diesel can be used as a substitute if it has an additive. Kerosene burns cleaner and is more refined than diesel, so it is generally the preferred option for use in heaters. However, some people choose to use diesel in their heaters due to its wider availability and lower cost.
If you are considering using diesel fuel in a kerosene heater, it is important to note that it may not be suitable for all heater types. Some sources suggest that diesel can be used in fan blast heaters or torpedo heaters, while others advise against using diesel in wick-type kerosene heaters as it may cause excessive sooting and smoking. It is always recommended to refer to the manufacturer's instructions or specifications for your specific heater model before attempting to use diesel fuel.
When using diesel as a substitute for kerosene, it is important to add an additive such as isopropyl alcohol. This additive helps improve the performance of the diesel fuel and can reduce potential issues such as smoke, odours, and fumes. It is recommended to mix diesel with unleaded fuel or gasoline in a ratio of 4:1 (diesel to gasoline) to achieve optimal results.
Additionally, it is worth noting that diesel fuel may not be suitable for long-term use in kerosene heaters. While it may work temporarily, kerosene is still the recommended fuel for prolonged periods. Kerosene heaters are designed specifically for burning kerosene, and using diesel as a substitute may impact the efficiency and performance of the heater over time.
Before using diesel fuel in a kerosene heater, it is essential to exercise caution and conduct thorough research. While some sources suggest that diesel can work as a substitute, others have reported mixed results. It is important to consider the potential risks, such as increased soot, smoke, and fumes, and make an informed decision based on your specific circumstances and the availability of alternative fuel options.

Kerosene burns cleaner than diesel
Kerosene is a lighter diesel oil than #2 diesel, which is why it is designated as #1 diesel. The lighter weight means it contains slightly less energy—approximately 135,000 BTU per gallon compared to 139,000 BTU for a gallon of #2 diesel. Kerosene burns drier and has less lubricity than #2 diesel, which can cause strain on fuel pumps and other engine parts.
Kerosene has a lower concentration of aromatic compounds, which are typically found in #2 and heavier diesel fuel oils. This is one of the main reasons why kerosene burns cleaner than diesel. Kerosene is also added to diesel during the winter to prevent it from thickening and solidifying in cold temperatures.
While kerosene burns cleaner, it is important to note that it has lower BTUs than diesel, which can reduce the power and efficiency of engines. Kerosene is also generally cheaper than diesel due to the road taxes added to the price of diesel fuel.
Some people choose to use diesel fuel in their kerosene heaters, especially in regions where kerosene is difficult to find or more expensive. However, it is not recommended as it can cause excessive smoke and soot buildup, making it a less desirable option.
In summary, kerosene burns cleaner than diesel due to its lower aromatic compound concentration and lubricity. It is also useful for winterizing diesel fuel and is generally more affordable. While kerosene has lower energy content, it is still a preferred choice for heaters and engines due to its cleaner burning properties and cost-effectiveness.

Using diesel in a kerosene heater may generate more carbon monoxide
Using diesel fuel in a kerosene heater is not recommended, as it can produce excessive amounts of carbon monoxide (CO) and soot, posing health and safety risks. While some people have used diesel in their kerosene heaters without issues, others have reported significant sooting and clogging, requiring tedious cleaning.
Kerosene heaters are specifically designed for kerosene fuel, which burns much cleaner than diesel. Using diesel can result in the release of higher levels of carbon monoxide, a colourless, odourless, and toxic gas. Exposure to carbon monoxide can be dangerous, causing symptoms such as headaches, dizziness, weakness, confusion, nausea, and even death in severe cases. Therefore, it is essential to prioritize the use of the correct fuel type to maintain a safe indoor environment.
The use of diesel #1, also known as Kerosene #1, as a substitute for kerosene in heaters has been suggested by some sources. However, it is recommended to supplement diesel #1 with an additive like isopropyl alcohol to ensure safe and effective use. It is important to exercise caution when considering this option, as improper use may lead to hazardous situations.
To ensure the safe and efficient operation of your kerosene heater, it is advisable to follow the manufacturer's instructions and use the specified fuel type. While diesel may be more readily available and cheaper, the risks associated with its use in kerosene heaters, such as increased carbon monoxide emissions and sooting, outweigh the potential benefits. Always prioritize safety and refer to reliable sources for guidance on fuel usage.
Although diesel engines are known to be more efficient than gasoline engines, emitting lower levels of carbon dioxide, their emissions can include harmful substances such as nitrogen oxides, soot, and fumes. Therefore, it is crucial to consider the specific context of using diesel in a kerosene heater, as it may lead to the generation of higher levels of carbon monoxide and other undesirable byproducts.

Kerosene is harder to find and more expensive than diesel
Kerosene is harder to find because it is a low-volume product. A user on a forum mentioned that the same station that sells hundreds of thousands of gallons of diesel may only sell a few hundred gallons of kerosene. Only a handful of stations sell kerosene at all, making it a low-volume product. This means that dealers have to charge more to make money, and there is not much competition to drive costs down.
Kerosene is also more expensive than diesel because it is a more refined fuel with fewer impurities. It is derived from petroleum and has a lower boiling point than diesel, which is why it is extracted first. Kerosene is also colourless, while diesel is reddish.
In some regions, kerosene is cheaper than diesel. For example, a user from Mississippi mentioned that kerosene is 20 to 30 cents less than road diesel in their area. However, this is not the case in most places, especially during the winter when kerosene is in higher demand. Typically, kerosene is around 40 cents more than diesel fuel, though the premium can vary from 20 cents to $1.
