Buying Guide
- Heating capacity and area: Match BTU output to the space size. Larger spaces need higher BTU units, but avoid excess heat in small rooms to prevent fuel waste.
- Ventilation and safety: Look for automatic shut-off, low-oxygen sensors, and CSA or equivalent certifications. Always ensure proper ventilation in indoor spaces.
- Fuel economy and runtime: Consider fuel efficiency and how long a tank will last. Some models run longer on a given propane cylinder, which affects operating cost and convenience.
- Ignition and startup: Pulse or electronic ignition improves reliability. Auto-on/off controls add convenience in variable environments.
- Portability vs. installation: Decide between portable units (for garages and worksites) and wall-mounted models (for long-term installations in cabins or sunrooms).
- Noise level: Some forced-air heaters can be noticeably louder. If you work in the space, prioritize models marketed as low-noise or with fans designed to minimize sound.
- Safety features: Ensure devices have tip-over, oxygen-deficiency, and overheat protections. CSA or UL listings provide additional assurance.
