Diesel / Kerosene Space Heater Buying Guide
Assess Heating Capacity (BTUs)
BTU Ratings: Diesel/kerosene space heaters are rated in British Thermal Units (BTUs), which measure their heating capacity. For example, a 70,000 BTU heater can heat up to 5,338 sq. ft. (496m3), while a 215,000 BTU model can handle up to up to 16,145 sq. ft. (1500m3)
Sizing Your Heater: Match the BTU rating to your space size and insulation level. Larger, less insulated areas require higher BTUs. Overestimating is preferable, as it allows for quicker heating and less strain on the heater. All heaters are equipped with a thermostat to prevent over heating the area.

Model | BTU Output | Heating Coverage (sq.ft.) | Heating Coverage (sq.m.) |
Hyundai HY70DKH | 70,000 BTU | Up to 5,338 sq. ft. | Up to 496 sq. m. |
Hyundai HY125DKH | 125,000 BTU | Up to 9,688 sq. ft. | Up to 900 sq. m. |
Hyundai HY215DKH | 215,000 BTU | Up 16,145 sq. ft. | Up to 1,500 sq. m. |
Consider Fuel Type and Availability
- Diesel vs. Kerosene: The Hyundai space heaters can run on either diesel or kerosene, but some other brands have to be adjusted for one fuel over the other. Diesel is generally more affordable and readily available, while kerosene burns cleaner, producing less odour and emissions.
- Local Availability: Ensure the fuel you choose is easily available in your area. Diesel is typically easier to find.
Portability and Design
Wheels and Handles: If you’ll need to move the heater frequently, look for models with built-in wheels and ergonomic handles. Larger units can be heavy, so portability features are essential and will also help in moving the heater to heat different areas as well to.
- Size and Weight: For smaller areas or intermittent heating needs, a compact heater might suffice. Larger heaters, while heavier, are ideal for large, open areas. As space heaters are usually used in the colder months, ensuring you have a portable and easy to transport space heater is important.

Safety Features
- Automatic Shut-off: This feature shuts down the heater if it tips over or overheats, protecting users and property from potential hazards.
- Flame-Out Sensors: These sensors detect if the flame goes out and will automatically turn off the fuel flow, preventing fuel leakage.
- Overheat Protection: This feature prevents the heater from operating at unsafe temperatures, extending its lifespan and keeping your space safer.
Heating Duration and Fuel Tank Size
- Fuel Tank Capacity: Larger tanks mean longer heating times without refueling. Look for a fuel tank that balances your need for continuous heat with the inconvenience of frequent refueling.
- Run Time: Heaters vary in efficiency; compare models for fuel consumption rates, typically stated as hours per liter A higher runtime per liter can mean significant savings over long-term use.
Ignition Type
- Electronic Ignition: Heaters with electronic ignition provide quick and reliable startup and are easier to use, particularly in cold conditions.
- Manual Ignition: Generally less expensive, but requires a bit more effort to ignite, especially in low temperatures.
Ventilation and Air Quality Considerations
- Proper Ventilation: Diesel and kerosene heaters emit carbon monoxide and other byproducts, so they must be used in well-ventilated areas. Look for models that are safe for your ventilation setup and avoid using them in confined spaces.
- Odor Control: Kerosene generally produces less odor than diesel. However, heaters with advanced combustion technology or built-in air filters can help reduce odors further.
Thermostat Control and Temperature Settings
- Adjustable Thermostats: Heaters with thermostats allow you to set a specific temperature. This maintains a comfortable level of heat, conserves fuel, and reduces the need for frequent adjustments.
- Multiple Heat Settings: If you need flexibility, look for heaters with multiple heat levels. This can help you manage fuel consumption and match heat output to your needs.
Maintenance Requirements
- Regular Maintenance: Diesel and kerosene heaters need periodic maintenance, such as cleaning or replacing the fuel filter, inspecting hoses, and clearing any fuel residues. Choose a model with accessible components for easy maintenance.
- Replacement Parts Availability: Heaters from reputable brands often have more accessible replacement parts and servicing options. This ensures your heater stays operational through multiple seasons.

Top Tips for Using Diesel/Kerosene Heaters Safely
- Only Use in Ventilated Areas: Never operate these heaters in enclosed spaces without ventilation. The risk of carbon monoxide buildup is significant.
- Monitor Fuel Quality: Using clean, high-quality fuel reduces odor, improves efficiency, and extends the heater’s life.
- Regularly Inspect and Maintain: Clean filters, check hoses, and inspect the heater for any leaks or damage. Routine maintenance ensures optimal performance and safety.
