Buying Guide
- BTU requirements: Match the unit’s BTU rating to your garage size, insulation, and climate. Larger spaces benefit from higher BTU units, but oversizing can lead to inefficiency and uneven heating.
- Fuel type and availability: Determine whether natural gas or propane is more practical for your locale and existing hookups. Propane units are versatile for detached spaces, while natural gas offers ongoing fuel supply if your home has gas service.
- Ventilation and venting options: Ceiling-mounted units often require venting; choose vertical or horizontal configurations based on space layout and building code compliance. Powered exhaust models can ease vent routing.
- Mounting and installation: Ceiling mounting requires sturdy supports and proper clearances. Check available brackets, required clearances from combustibles, and electrical connections (voltage and amperage).
- Efficiency and continuous operation: Look for units with solid efficiency ratings and reliable ignition systems. Self-diagnostic controls help monitor performance and reduce downtime.
- Maintenance and serviceability: Accessibility of service ports, thermostats, and gas connections influences maintenance ease. Some models provide easier outside access for components like thermostats.
- Safety features: Ensure units have proper shutoff mechanisms, adequate ventilation, and compliance with local codes. Installation should follow manufacturer instructions and building codes.
- Space planning: Consider ceiling height, air distribution, and whether you need additional fans or ducting to improve warm-air spread.
- Warranty and support: Review warranty terms and the availability of parts or service technicians in your area to minimize downtime.
