Kerosene heaters are illegal in Massachusetts and California
Kerosene heaters are illegal in Massachusetts due to the increased risk of fire and carbon monoxide poisoning. The State's Fire Marshal's Office has stated that kerosene heaters cannot be sold or used in places of residence. The use of such heaters is punishable by a fine of $100 or more.
The National Kerosene Heater Association, Inc. ("NKHA"), challenged the constitutionality of the Massachusetts laws banning the sale and use of unvented liquid-fired kerosene heaters. However, the court ruled that the ban was not preempted by the Consumer Product Safety Act ("CPSA").
Massachusetts first enacted statutes regulating kerosene heaters in 1962, addressing the risks associated with old-style heaters that had a high center of gravity, making them prone to tipping over. Over time, safety features were added to heaters, including low centers of gravity, tip-over switches, shut-off devices, and fuel storage limits. Despite these advancements, the use of kerosene heaters remains prohibited in the state.
In California, the use of kerosene heaters is also illegal. While specific details about the regulations in California are not readily available, it is clear that both Massachusetts and California have taken steps to ban the use of kerosene heaters due to safety concerns.
Regarding the use of diesel fuel in kerosene heaters, it is important to exercise caution. Some sources claim that using diesel fuel can cause excessive soot buildup and even ruin the heater. However, others have reported successfully using diesel fuel in kerosene heaters, especially in older-style "jet" heaters or in shop settings. It is recommended to use kerosene heaters only with the fuel they are manufactured for and to prioritize safety when operating these heaters.

Kerosene heaters are designed to run on 1-K kerosene
Using the correct fuel type is crucial for the safe operation of kerosene heaters. The National Kerosene Heater Association, the American Petroleum Institute, and the Consumer Product Safety Commission all recommend using only 1-K kerosene in these heaters. Using other fuels, such as diesel, can be dangerous and may result in a fire or explosion.
Diesel fuel, even when supplemented with isopropyl alcohol, is not recommended for use in kerosene heaters. While some people have used diesel fuel in their kerosene heaters without immediate issues, it is not the correct fuel and can cause problems over time. Diesel fuel tends to generate more soot and carbon monoxide, which can be hazardous to health and require frequent cleaning of the heater.
Additionally, the use of impure fuel in kerosene heaters can lead to clogging of the wick, affecting the heater's performance. Kerosene heaters with dirty wicks may experience incomplete combustion, producing carbon monoxide, which is a colorless and odorless gas that can be deadly. Therefore, it is essential to use only the specified 1-K kerosene fuel and to regularly clean and maintain the heater according to the manufacturer's instructions.
In summary, kerosene heaters are designed to run on 1-K kerosene, and using other fuels, such as diesel, can pose safety risks and performance issues. It is crucial to follow the manufacturer's instructions and take the necessary precautions to ensure the safe and proper use of kerosene heaters.

Using diesel in a kerosene heater may cause smoke and soot
While there are some suggestions that diesel can be used as a substitute for kerosene in heaters, this is not recommended. Kerosene heaters are designed to run on 1-K kerosene, which has been refined to burn cleanly and efficiently. Using diesel in a kerosene heater may cause smoke and soot, which can be a health and safety issue.
Several people have reported that using diesel in their kerosene heaters resulted in a build-up of soot inside the heater, causing a mess and making the room smoky. One person reported that using diesel in their kerosene heater caused smoke and soot, requiring them to take the heater apart for cleaning. Another person reported that using diesel in their kerosene heater made the room so smoky that it made their eyes sting.
Diesel is thicker than kerosene and may clog the injector of a kerosene heater. It is also more difficult to ignite, as it requires a fine mist of fuel under pressure to burn efficiently. Kerosene, on the other hand, burns cleanly and does not require vaporization to ignite.
While some people have reported using diesel in their kerosene heaters without issue, it is important to note that this is not the intended fuel for these heaters and may cause damage or health issues. It is always best to use the correct fuel type specified by the manufacturer to ensure optimal performance and safety.
To find kerosene for your heater, try contacting your local fuel distributor or searching for a bulk fuel distributor in your area. Some rural gas stations may also have kerosene available, and it can sometimes be found in hardware stores in the paint department.

Kerosene is more expensive than diesel
Kerosene heaters are illegal in some places, such as Massachusetts, which may be why some people are unable to find kerosene at fuel stations. Kerosene is also more expensive than diesel, with prices ranging from $11 to $15 per gallon at department stores and retail stores.
However, some people have found cheaper options by buying kerosene in bulk from a local fuel distributor or a gas station with a kero pump. For example, one person reported finding kerosene for less than half the price of Lowe's $5 gallon cans at a Hess Station. Another person found kerosene for $4.19 per gallon, compared to $3.95 per gallon for diesel at the same station.
The price difference between kerosene and diesel may be due to the federal road tax on diesel, which is $.248 per gallon in the United States. Kerosene, on the other hand, does not have this tax included, which may make it a more cost-effective option for some people, despite its higher retail price.
While some people have successfully used diesel fuel in their kerosene heaters, it is not recommended as it can cause a lot of smoke and soot, and may damage the heater over time. Therefore, it is important to consider the potential costs of repairing or replacing a heater damaged by using the wrong type of fuel.

Kerosene is easier to find in rural areas
Kerosene is a combustible hydrocarbon liquid derived from petroleum. It is a widely used fuel for aviation, cooking, lighting, and heating purposes. Kerosene is also used as a cleaning liquid, on bike chains and rims to remove lubricants. In some countries, it is the predominant fuel for cooking, lighting, and heating, especially in rural areas with limited access to electricity.
In rural areas, kerosene may be easier to find due to its widespread use and availability. In Japan, Chile, the United Kingdom, Ireland, and Nigeria, kerosene is commonly used for heating and cooking, particularly in areas without access to gas pipelines or the national grid. In these regions, kerosene can be readily purchased at filling stations or delivered directly to homes.
In the United States, kerosene was historically the primary commercial end-use for petroleum refining until it was surpassed by motor fuels in 1909. Today, kerosene is still used in the US, particularly in rural areas, for lighting, heating, and cooking. Some states, like Massachusetts and California, have restrictions on kerosene heaters, which may impact its availability in certain regions.
To find kerosene in rural areas, individuals can search for bulk fuel distributors or contact local fuel stations to inquire about kerosene availability. In some cases, kerosene may be purchased from a nearby gas station or obtained from a bulk fuel distributor at a lower cost than buying it by the gallon.
While kerosene is accessible in many regions, it is important to note that it has detrimental environmental and health impacts. As such, it is advisable to explore renewable energy sources and energy-efficient alternatives to reduce reliance on kerosene, particularly in rural areas.
