Buying Guide
- BTU range and space size: Choose a heater with BTU output appropriate for the area you intend to heat. Larger spaces may require 12,000–18,000 BTU or more, while smaller patios can be comfortable with 6,000–9,000 BTU.
- Indoor vs. outdoor ventilation: Propane heaters burn fuel and release combustion byproducts. Only use in well-ventilated areas or outdoors, and heed manufacturer guidance about indoor use as some models are designed for ventilated indoor spaces.
- Safety features: Look for oxygen depletion sensors (ODS), tip-over switches, automatic shut-off, and heat shields. These features improve safety in high-traffic or mixed-use spaces.
- Portability and setup: If you plan to move heat around a property, consider models with integrated handles, wheels, or compact profiles. For emergency use, a self-contained cabinet design with the tank integrated can simplify storage.
- Fuel source and tank compatibility: Ensure you have access to standard 20 lb propane tanks and that hoses and regulators are included or readily available. Some units include regulator hoses, while others require separate purchases.
- Run time and fuel efficiency: Check listed run times at different BTU settings. Longer runtimes are beneficial during outdoor gatherings or power outages when refueling opportunities may be limited.
- Durability and weather resistance: Outdoor units should withstand wind, rain, and cold temperatures. Look for weather-resistant coatings and secure bases to prevent tipping in breezy conditions.
- Noise and comfort: Some models operate quietly, while others produce noticeable fan-like sounds or burner noise. Consider the environment and tolerance for noise in occupied spaces.
- Maintenance: Regularly inspect hoses and regulators for signs of wear. Clean the vents and ensure the ODS sensor functions correctly to maintain safe operation over time.
