Buying Guide: Indoor Heating Without Electricity

What fuel type should you choose?

Propane heaters provide clean, quick heat with easy fuel management but require ventilation in enclosed spaces. Kerosene heaters offer longer run times and can function well in larger areas, but kerosene handling and odor management are important. Choose propane for indoor main heat in well-ventilated rooms; choose kerosene for longer off-grid sessions or when camping away from power.

Where will you place the heater?

For indoor use, prioritize units with clear safety shut-offs, tip-over protection, and proper ventilation. For outdoor or semi-enclosed spaces, rugged outdoor-rated models with wind resistance are beneficial. Always keep heaters away from flammables and ensure stable placement on a flat surface.

How much area needs heating?

Smaller spaces up to about 200 square feet are typically well-covered by 4,000–6,000 BTU units. Larger rooms or garages may require 8,000–9,000 BTU or higher, depending on insulation and climate. If you anticipate frequent use, opt for a model with adjustable heat output to balance warmth and fuel consumption.

Safety and setup considerations

• Ensure adequate ventilation when operating in enclosed spaces
• Store fuel safely away from heat sources and children
• Use on stable, non-flammable surfaces with clearances from walls and curtains

Fuel availability and maintenance

Check local availability of propane and kerosene in your area. Regularly inspect fuel lines, regulators, and ignition components. Have a plan for refueling to avoid running out during a cold spell.
