- Power independence: Propane models generally run without electricity, which is advantageous during outages or in outdoor spaces without power outlets.
- Durability and ventilation: Built-for-purpose outdoor heaters require proper ventilation and weather-resistance materials for extended outdoor use.
- Fuel considerations: Use compatible propane cylinders (commonly 20-lb) and ensure safe storage and handling to maintain performance and safety.
