Buying Guide: How To Choose A Portable Gas Heater
1. Heat Output (BTU) And Coverage: Match BTU to the space size and insulation. Lower BTU (4k–9k) suits small tents and campers. Mid-range (9k–18k) covers garages and larger tents. High-output units (30k+) are best for open patios and directional outdoor zones.
2. Fuel Type And Runtime: Most portable gas heaters use propane (LP). Consider whether you want compatibility with 1 lb. cylinders for transport or adapters for 20 lb/40 lb tanks for longer runtime. Fuel availability and transport restrictions should factor into selection.
3. Indoor Use And Ventilation: Not all gas heaters are indoor-safe. Look for models explicitly rated for indoor use and observe CO monitoring and ventilation requirements. Use only in well-ventilated spaces and follow manufacturer guidance for enclosed areas.
4. Safety Features: Key safety components include tip-over shutoff, flame failure/thermocouple protection, and automatic gas shutoff. Audible or visible safety indicators and robust guards reduce burn/tip hazards.
5. Ignition And Controls: Piezo or push-button ignition avoids matches; multi-stage control knobs provide finer temperature control. Simpler controls reduce complexity for rapid outdoor setups.
6. Portability And Build: Weight, handle design, and dimensions determine transport ease. Rugged construction and weather-resistant finishes benefit worksite and outdoor use.
7. Directional Heating And Design: Radiant vs. convective output matters: radiant heaters warm people/objects directly and work well in drafts, while convective heaters warm the air and suit enclosed spaces.
8. Attachment And Accessory Options: Check for optional hoses, filters, or adapters that permit use with larger tanks or extend runtime. Some models accept top-mount tank attachments for quick setup.
9. Maintenance And Longevity: Look for accessible burner areas, replaceable igniters, and corrosion-resistant coatings. Regular inspection of hoses, fittings, and seals is essential for safe operation.
10. Use Case Comparison:
- Camping/Tent Use: Prioritize compact, lower-BTU, indoor-safe or well-ventilated-rated models with reliable igniters.
- Garage/Workshop: Mid-to-high BTU with tilt or directional features and stable bases are desirable; ensure ventilation for combustion products.
- Patio/Outdoor: Larger BTU tank-top or double-burner units deliver broad coverage; match/light or manual ignition may be acceptable outdoors.
- Job Site/Industrial: Heavy-duty forced-air heaters for large volumes are best; confirm fuel type (natural gas vs. propane) and rugged build.
11. Regulations And Safety Practices: Follow local laws for fuel transport and use. Never leave gas heaters unattended, and always keep combustible materials at safe distances. Use carbon monoxide detectors where combustion occurs near occupied spaces.
12. Warranty And Support: Compare warranty length and manufacturer support for parts and diagnostics—especially important for commercial or frequent-use buyers.
