Buying Guide
- Fuel type: Decide between propane or natural gas based on available connections, running costs, and convenience. Ventless models offer flexibility but may require adequate ventilation in some spaces.
- Installation: Consider wall-mount vs. floor-mounted options. Garages often benefit from wall-mounted units to maximize floor space and ease of access to storage.
- Heat distribution: Blue flame and infrared options heat air or objects efficiently. For open layouts, a higher BTU and proper placement reduce cold spots.
- Space coverage: Verify the approximate square footage coverage and match to your garage size. Additional insulation improves overall efficiency.
- Thermostat control: Models with adjustable thermostats help maintain a steady temperature and save energy when not needed.
- Ventilation and safety: Ventless units require proper clearance and carbon monoxide considerations. Ensure installation follows local codes and manufacturer guidelines.
- Maintenance: Look for easy filter access, cleanable surfaces, and clear service instructions in the event of issues or seasonal storage.
- Reliability and warranties: Check manufacturer warranties and available replacement parts for long-term support in garage environments.
