Buying Guide: How To Choose A Convection Kerosene Heater

Heating Capacity And Coverage: Compare BTU ratings and the manufacturer’s stated square-foot coverage. For open living areas or workshops, look for units in the 23,000–24,000 BTU range to cover ~900–1,000 sq. ft. Smaller spaces can use lower BTU models for efficiency.

Fuel Tank Size And Run Time: Tank capacity (commonly 1.1–1.9 gallons) affects runtime. Larger tanks deliver longer operation between fills. Consider how many hours of run time you need during outages and the fuel storage logistics.

Ignition Type: Wick-only systems rely on manual lighting and wick maintenance. Models with electronic or push-to-start ignition simplify startup and may require batteries. Choose based on user comfort with maintenance and available supplies.

Safety Features: Look for automatic shut-off, tip-over protection, and protective guards. Confirm UL or similar safety listings if available. Remember that safety interlocks reduce risk but do not eliminate the need for proper placement and ventilation.

Indoor Use Considerations: Kerosene combustion produces moisture and combustion byproducts. Ensure adequate ventilation and carbon monoxide detection when operating indoors. Follow clearance recommendations to prevent fire hazards and surface damage.

Portability And Placement: If you plan to move the heater between rooms or use it in a garage or workshop, consider weight, handle design, and stable base. Convection heaters benefit from elevated placement in colder basements to distribute warm air upward.

Maintenance And Consumables: Wick systems require periodic trimming or replacement and use clean kerosene for best results. Electronic ignition units may need battery replacements. Check availability of replacement wicks and user-serviceable parts.

Emissions And Indoor Air Quality: Even well-maintained kerosene heaters emit combustion byproducts. Use only recommended fuel, maintain the unit per instructions, and run in ventilated spaces. Combine with a carbon monoxide alarm and follow local regulations.

Noise And Heat Distribution: Convection heaters are typically quiet compared with forced-air units. Assess how evenly a model distributes heat in mock setup scenarios; larger convection units work better in open areas, while smaller models can be effective in zoned heating.

Redundancy And Emergency Planning: For emergency preparedness, consider having a smaller backup unit and extra fuel stored safely. Confirm how long a unit can run unattended with its safety features and plan placement near exits for convenient refueling if necessary.

Warranty, Support, And Certifications: Review manufacturer warranty details and available customer support. Certifications such as UL listing or similar third-party safety approvals provide additional assurance regarding construction and safety standards.
