Heating Oil vs Kerosene: Which Is Better for Your Home?

Choosing the right fuel for your home heating system plays a major role in comfort, efficiency, and long-term running costs. Two of the most common liquid fuels used for domestic heating are heating oil and kerosene. While they may appear similar, each fuel has distinct characteristics that can affect how well it performs in your home.

At Kenny Fuels, we supply both heating oil and kerosene and regularly help customers decide which option best suits their heating system and household needs. This guide explains the key differences, benefits, and considerations so you can make a confident and informed choice.

 

Understanding Heating Oil and Kerosene

Heating oil and kerosene are both petroleum-based fuels used in boilers, furnaces, and some space heaters. However, they differ in composition, viscosity, and how they burn.

Heating oil is thicker and heavier, which means it burns slightly slower and is often used in systems designed specifically for oil-fired heating. Kerosene, on the other hand, is lighter and more refined, allowing it to ignite more easily and burn cleaner.

Although both fuels can effectively heat your home, the type of system you have and your heating priorities will influence which option is more suitable.

 

Heat Output and Efficiency

One of the main concerns for homeowners is the amount of heat a fuel produces and how efficiently it does so.

Kerosene generally:

  • Burns hotter than standard heating oil
  • Reaches operating temperature more quickly
  • Provides a consistent and stable flame

Heating oil:

  • Offers strong, steady heat output
  • Is well suited for traditional oil boilers
  • Performs reliably in systems designed for heavier fuels

If your system is compatible with both, kerosene may provide slightly better efficiency, particularly in newer or high-efficiency boilers.

 

Cleanliness and Maintenance

The cleanliness of a fuel affects not only indoor air quality but also the condition of your heating system.

Kerosene burns more cleanly, producing:

  • Less soot
  • Fewer carbon deposits
  • Reduced risk of burner clogging

This can lead to fewer service call-outs and potentially longer equipment lifespan.

Heating oil tends to produce more residue during combustion, which may require more frequent servicing and cleaning of burners and filters. However, when properly maintained, systems using heating oil still perform very well.

 

Cold Weather Performance

Cold temperatures can impact how fuels flow through pipes and filters.

Kerosene remains fluid at lower temperatures, making it:

  • Less likely to thicken or gel
  • More reliable in colder climates
  • Better suited for outdoor tanks

Heating oil can become thicker in very cold conditions, which may affect fuel flow if tanks and lines are not well protected.

For homes exposed to colder weather, kerosene is often the preferred option.

 

Cost Considerations

Price is an important factor for many households.

Heating oil is usually:

  • Less expensive per litre
  • More economical upfront

Kerosene typically:

  • Costs slightly more per litre
  • May offer savings over time through improved efficiency and lower maintenance

The best choice depends on whether you prioritise a lower purchase price or long-term performance benefits.

System Compatibility

Not all heating systems are designed to run on both fuels.

Before choosing, you should:

  • Check your boiler or burner specifications
  • Confirm manufacturer recommendations
  • Speak with a heating professional or fuel supplier

Using the wrong fuel can reduce efficiency or cause damage, so compatibility is essential.

 

Which Fuel Is Best for Your Home?

There is no one-size-fits-all answer.

Heating oil may be ideal if:

  • You have a traditional oil boiler

  • You want a lower-cost fuel option

  • Your system is specifically designed for heating oil

Kerosene may be better if:

  • You have a modern or high-efficiency boiler

  • You want cleaner combustion

  • You experience cold weather conditions

  • You want reduced maintenance needs

The right choice depends on your system type, budget, and heating goals.
