Buying Guide: How To Choose A Portable Propane Space Heater
Choosing the right portable propane heater depends on how you plan to use it. Below are key purchase considerations to evaluate before buying.

Heating Output And Coverage
BTU Rating Indicates Heat Output. Lower BTUs (4,000–9,000) Fit Small Tents And Campers. Mid-Range Units (10,000–18,000) Suit Garages, RVs, And Patios. High-Output Forced-Air Models Serve Large Job Sites But Are Less “portable” for casual use.
Heating Type: Radiant Vs. Forced-Air
- Radiant Heaters Directly Warm People And Objects; Efficient For Spot Heating And Outdoor Use.
- Forced-Air Heaters Move Warm Air And Can Heat Larger Volumes Faster, But They Tend To Be Louder And Use More Fuel.
Fuel Source And Runtime
Most portable units run on disposable 1 lb. cylinders or standard 20 lb. tanks. Tank-top designs mount directly to a 20 lb. tank for simplicity. If you need extended runtime, choose models that connect to larger tanks or support dual-tank setups.
Portability And Setup
Consider weight, handle design, and whether the heater requires hoses or regulators. Tank-top units minimize accessories, while some variable-output models need additional hoses for larger tanks. For travel, smaller units and those using 1 lb. cylinders can be more convenient.
Safety Features
- Tip-Over Shutoff: Prevents operation if knocked over.
- Low-Oxygen Shutoff (ODS): Important For Indoor Or Enclosed Use To Detect Unsafe Oxygen Levels.
- Pierzo Igniter Or Matchless Start: Simplifies ignition and reduces the need for external lighters.
Intended Use And Approved Locations
Check Manufacturer Guidelines For Indoor Vs. Outdoor Use. Some “indoor-safe” radiant heaters are approved only for ventilated spaces such as campers with ventilation; forced-air high-output models are often for outdoor or well-ventilated job sites only.
Noise And Comfort
Forced-air heaters can generate significant noise, while radiant units are typically quieter. If noise matters for your setting, prioritize radiant or quieter forced-air models.
Durability And Weather Resistance
For permanent outdoor setups or frequent use in rough conditions, look for corrosion-resistant materials and a stable base or mounting options. Tabletop and portable units are generally less weatherproof and should be sheltered during inclement weather.
Size And Coverage Comparison
| Aspect | Small Radiant (4k–9k) | Mid Radiant (10k–18k) | Forced-Air / High Output |
|---|---|---|---|
| Best For | Campers, small tents | Garages, patios, RVs | Large workspaces, outdoor events |
| Coverage | Up To ~225 sq. ft. | Up To ~450 sq. ft. | Large open areas; moves air |
| Portability | Very high | High | Moderate; heavier |
Maintenance And Parts
Regularly inspect hoses, regulators, and connections for leaks. Piezo igniters generally require less maintenance than electronic starters. Replace worn seals and keep the reflector and burner areas clear of debris to maintain efficiency.
