Buying Guide
- Heat coverage: Match BTU output to space size. Larger spaces benefit from higher BTU units, while smaller garages may do well with mid-range models.
- Thermostat control: Prefer adjustable thermostats for consistent warmth and fuel efficiency. Verify that the thermostat is integrated with the unit or compatible with an external control.
- Run time and fuel source: Consider 20 lb tank compatibility and expected runtime at different settings. Longer runtimes reduce tank changes during projects.
- Ventilation and safety: Ensure proper ventilation in enclosed spaces. Look for auto shutoff, tilt safety, and flame-out protection for safe operation.
- Portability vs. durability: Heaters with heavy-duty housings and built-in handles suit job sites, while lighter models fit small workshops or temporary setups.
- Hose and regulator: A long hose (10 ft or more) helps reach tanks, especially on larger jobsites. A regulator ensures stable gas flow.
- Noise level: Quiet burner technologies reduce noise; consider your work environment and whether noise is a concern.
FAQ
