Buying Guide: Key Purchase Considerations
- Fuel type and availability: Decide between propane and natural gas based on existing hookups and fuel efficiency. Propane offers portability, while natural gas provides a steady supply if a line is already available.
- Heat output and coverage: Choose BTU ratings aligned with your garage size. Larger spaces typically require higher BTU models, but consider insulation and ceiling height to avoid overheating.
- Thermostat control: Look for adjustable High/Medium/Low settings to maintain a comfortable temperature and save fuel costs.
- Ventless design and safety: Ventless units simplify installation but require proper clearance and vent-free operation guidelines. Ensure the heater includes shutoff features and adequate clearance from combustibles.
- Mounting options: Wall-mounted versus floor-standing (base feet) configurations affect space planning and ease of access for thermostat controls and maintenance.
- Durability and warranty: Heaters designed for garage use should feature robust construction and reputable warranties. Consider corrosion resistance and ease of serviceability.
- Noise and airflow: Infrared models focus heat on objects and occupants with less ambient airflow, while blue flame models distribute heated air more broadly—evaluate which pattern fits your space.
- Installation considerations: Some units require venting or compliance with local codes. Verify installation requirements before purchasing and ensure proper venting coverage if needed.
