Buying Guide
What to consider when choosing a portable LP gas heater
- Room size and heat output: Match BTU range to the area you aim to heat. Larger spaces need higher BTU like 18,000 BTU; smaller spaces fit 9,000 BTU or less.
- Ventilation: LP heaters burn propane; ensure adequate ventilation in enclosed spaces. Some units are certified for indoor use, others require outdoor or semi-outdoor placement.
- Safety features: Look for tip-over shut-off, oxygen depletion sensors, and flameout protection. These reduce risk in busy rooms or with children and pets.
- Portability and setup: Consider built-in handles, wheels, or table-top design. Also check whether you need a hose or regulator included.
- Fuel considerations: Propane cylinders are standard. Check compatibility with cylinder size (e.g., 20 lb tanks) and whether you need quick-connect hoses.
- Runtime and efficiency: Some models run longer on the same tank. Compare BTU output and fuel consumption to estimate runtime.
- Outdoor vs. indoor use: Indoor-rated units require proper ventilation and space clearance. Outdoor or garage use often allows higher BTU and more expansive heating zones.
