Buying Guide: How To Choose A Propane Outdoor Heater
Heat Output (BTU) And Coverage
BTU rating indicates maximum heat output. Smaller tabletop or portable units commonly range from 4,000–18,000 BTUs, suitable for targeted or close-range heating. Standing patio heaters and commercial units typically range from 40,000–50,000 BTUs for broader coverage. Choose based on the area you need to heat and whether you need directional or ambient warmth.
Type Of Heater
Three common types are:
- Portable Radiant Heaters: Provide direct, sun-like warmth to people and objects—efficient for close seating.
- Standing Patio Heaters: Use a reflector to spread heat over a wider area—better for groups and larger patios.
- Tabletop Heaters: Compact for small gatherings or where floor space is limited; lower BTU output.
Fuel Options And Tank Compatibility
Most outdoor propane heaters use 1 lb. disposable cylinders or standard 20 lb. tanks. Some units support larger 40 lb. tanks via an accessory hose. Consider runtime, convenience, and whether you want portability (lighter tanks) or longer continuous use (larger tanks).
Safety Features
Essential safety features include tip-over shutoff, flame failure/oxygen depletion sensors (especially for partially enclosed areas), and sturdy bases to resist tipping. For public or commercial use, ETL or CSA certification indicates compliance with recognized safety standards.
Portability And Installation
Wheels and lighter construction improve mobility. Portable radiant models are ideal for moving between locations; standing units often require assembly and a stable surface. Consider storage footprint and whether the heater needs to be anchored for safety in windy areas.
Durability And Materials
Look for corrosion-resistant materials like stainless steel or powder-coated steel, and protected burners or mesh in higher-use environments. Commercial-use heaters benefit from heavier gauges and protective covers to extend service life.
Ignition And Controls
Piezo or electronic ignition systems allow matchless starts. Variable knobs permit adjusting heat output to manage fuel consumption. One-touch ignition and simple control layouts are useful for frequent on/off use in hospitality settings.
Coverage vs. Wind And Outdoor Conditions
Open-air conditions reduce effective coverage. Radiant units perform better in breezy conditions because they heat objects directly, while ambient radiant standing heaters may be less effective in strong wind. Consider windbreaks, overhead covers, and arrangement of seating when planning heater placement.
Maintenance And Cleaning
Periodic cleaning of reflectors, burners, and air intakes helps maintain efficiency. Stainless or coated materials simplify maintenance. Verify availability of replacement parts such as valves, hoses, regulator kits, and mesh guards to extend product life.
Application Scenarios
- Small Tabletop Areas: Compact tabletop heaters (4k–11k BTU) for intimate seating.
- Medium Patios: Portable or mid-output standing units (18k–46k BTU) for family patios.
- Large Or Commercial Spaces: High-output models (46k–50k BTU) designed for restaurants and event spaces.
Comparing specifications—BTU, coverage, fuel type, safety certifications, and construction materials—helps match a heater to the intended outdoor use while accounting for wind and layout. Choose units with appropriate safety features and durable construction for long-term outdoor exposure.
