Kerosene heaters are better suited to diesel #1, but diesel #2 can be used with an additive
Kerosene heaters are designed to run efficiently on 1K kerosene and burn cleanly if properly maintained. Kerosene is a lighter and thinner fuel that ignites at a lower temperature than diesel. Diesel, on the other hand, works best when sprayed in a fine mist from a nozzle under pressure. As a result, diesel #1 can be used as a substitute for kerosene in heaters, as long as it has an additive such as isopropyl alcohol.
However, diesel #2 is not recommended for use in kerosene heaters as it is thicker and can clog the injector. It also burns less cleanly, producing more soot and potentially harmful fumes. If you attempt to use diesel #2 in a kerosene heater, you may experience issues with the wick, which can become coated in hardened creosote and difficult to shut off.
To mitigate these issues, some people have suggested adding more of an additive to diesel #2, such as blending or cutting the diesel with gasoline to thin it. Others have recommended periodically performing a dry burn, allowing the heater to burn completely out of fuel to burn off any char on the wick.
While it is possible to use diesel #2 in a kerosene heater with these modifications, it is important to prioritise safety. Ensure proper ventilation and consider investing in a carbon monoxide detector. Additionally, always refer to the manufacturer's instructions for your heater, as using the wrong fuel may pose health and safety risks.

Kerosene is harder to find and more expensive than diesel
One way to save money on kerosene is to buy it in bulk. For example, purchasing 55-gallon drums from a local fuel supplier can significantly reduce the price per gallon. However, this option may not be feasible for everyone, especially those who do not require such a large quantity of kerosene.
In contrast, diesel fuel is more widely available and generally cheaper than kerosene. This price difference is particularly notable when comparing the cost of diesel to the retail price of kerosene sold by the gallon at hardware stores.
The high cost of kerosene is one of the reasons why some people consider using diesel fuel in their kerosene heaters. While diesel may be a viable alternative in certain cases, it is important to note that it is not the recommended fuel for kerosene heaters and may cause issues such as wick hardening and increased soot and crust buildup.
Therefore, while diesel may be more readily available and affordable than kerosene, it is important to carefully consider the potential drawbacks and take necessary precautions if choosing to use it in a kerosene heater.

Diesel may be harder to ignite in a kerosene heater
While diesel fuel can be used in a kerosene heater, there are some important differences between the two fuels that can make diesel harder to ignite.
Firstly, diesel is less volatile than gasoline, which means it has a higher flash point. The flash point is the minimum temperature at which a liquid can produce enough vapours to form an ignitable mixture with air near the surface of the liquid. In other words, diesel requires higher temperatures to ignite compared to gasoline. This is because diesel has many more straight-chain hydrocarbons, which are less susceptible to vapourisation and ignition.
Secondly, diesel engines operate differently from gasoline engines. Diesel engines use compression to ignite the fuel mixture, rather than a spark. This means that diesel engines require intense pressure or sustained flame to ignite the fuel. In contrast, gasoline engines use spark plugs to ignite the fuel, which is why gasoline has a lower flash point and is more volatile.
Additionally, diesel tends to be thicker than kerosene, which can clog the injector of a kerosene heater. This can make it harder for the diesel to ignite properly, as the heater may not be designed to accommodate the thicker fuel.
Furthermore, using diesel in a kerosene heater may lead to the production of more soot and carbon buildup on the wick, which can hinder ignition. The wick may need to be cleaned or replaced more frequently when using diesel fuel.
Overall, while it is possible to burn diesel fuel in a kerosene heater, it may be harder to ignite due to the inherent properties of diesel and the design of kerosene heaters. It is important to exercise caution and ensure proper ventilation when burning diesel to avoid any potential health risks associated with incomplete combustion.

Kerosene burns cleaner than diesel
However, diesel is more readily available and can be cheaper than kerosene. Kerosene heaters are also harder to find in some places, such as north of Boston, and in certain states like Massachusetts, they are illegal.
Some people have reported using diesel in their kerosene heaters without issue, but others have noted that it can be challenging to clean afterward. Diesel also tends to produce a strong smell.
If you do choose to use diesel in a kerosene heater, it is important to ensure that it burns hot and that the wick height is adjusted correctly. Additionally, you may need to periodically perform a dry burn, letting the heater burn completely out of fuel, to remove any char from the wick.
Overall, while diesel may be more accessible and affordable, kerosene burns cleaner and produces less soot and smell.

Kerosene heaters can be safely used with diesel, but it may not be the best option
Kerosene heaters can be safely used with diesel fuel, but it may not be the best option. While some people have used diesel in their kerosene heaters without any issues, others have reported problems with wicks getting clogged and hardened, making it difficult to turn off the heater. To mitigate this, it is recommended to do a dry burn every three gallons, allowing the heater to burn completely out of fuel, preferably outdoors, to remove any char from the wick.
Additionally, diesel fuel tends to produce more soot and smoke, which can be messy and require additional cleaning. It may also be challenging to ignite diesel fuel in a kerosene heater, and it might not burn as cleanly as kerosene, especially if it is diesel #2, which is less refined. Kerosene heaters are designed to run efficiently on 1K kerosene and burn cleanly with proper maintenance. Using diesel fuel may also result in increased fumes and a stronger odour, although this can be somewhat improved by using ultra-low sulfur diesel fuel.
When considering the use of diesel fuel in a kerosene heater, it is essential to prioritize safety. Kerosene heaters may not be approved for indoor use with diesel fuel due to potential health risks. It is recommended to use well-ventilated areas and invest in a carbon monoxide detector to mitigate potential hazards. It is also crucial to follow the manufacturer's instructions and only use the recommended fuel type for your specific heater model to ensure optimal performance and safety.
While diesel fuel can be a viable option in certain situations, such as when kerosene is unavailable or more expensive, it is generally advisable to use kerosene in kerosene heaters whenever possible. Kerosene is designed to burn very cleanly and efficiently, especially in wick-type heaters, and it is crucial to consider the potential trade-offs in terms of performance, maintenance, and safety when opting for diesel fuel.
In conclusion, while it is technically possible to use diesel fuel in a kerosene heater, it may not be the optimal choice. Kerosene heaters are designed for kerosene, and using diesel fuel may lead to operational challenges, increased maintenance, and potential health and safety concerns. Therefore, it is recommended to prioritize using kerosene whenever feasible to ensure the best performance and minimize risks associated with alternative fuel types.
