Buying Guide: How To Choose The Right 20 lb Propane Tank Heater
- Space size: Larger areas benefit from higher BTU ratings (e.g., 30,000–45,000 BTU). For small patios, 9,000–15,000 BTU may be sufficient.
- Heat type: Infrared models provide immediate warmth on contact, which is useful in outdoor settings with little airflow. Radiant models also perform well in windy conditions when properly shielded.
- Portability: Tank-top designs are typically easy to transport, but consider dual-head or trolley options if you move the heater frequently.
- Safety features: Look for tip-over switches, automatic gas shut-off valves, and sturdy guards to reduce risk in high-traffic areas.
- Fuel and compatibility: Ensure the unit is designed for standard 20 lb tanks and replaceable propane cylinders for easy fuel management.
- Setting and maintenance: Check for simple assembly, minimal assembly time, and maintenance requirements like cleaning guards and checking hoses.
