Buying Guide For Garage Gas Heaters
Selecting a garage gas heater involves several key considerations to ensure efficient and safe heating:
1. BTU Heating Capacity
Evaluate the size of your garage or workshop to determine the necessary BTU output. Larger spaces generally require higher BTU heaters, such as the Mr. Heater Big Maxx at 80,000 BTU, while smaller areas may only need 30,000 to 45,000 BTU units.
2. Fuel Type Compatibility
Most garage gas heaters run on natural gas or propane. Ensure the heater matches your available fuel source. Some models come with conversion kits, but others, like the Dyna-Glo infrared heater, do not allow fuel alterations.
3. Installation Options
Consider mounting preferences — ceiling, wall, or floor. Ceiling mounting frees up floor space and may offer better heat dispersion. Verify mounting hardware is included or needs to be purchased separately.
4. Heating Technology
Infrared heaters warm objects and people directly, providing quick localized heat. Forced air models circulate warm air for more general heating. Choose based on your garage layout and heating needs.
5. Noise Level
Quiet operation is desirable for garages that are frequently occupied or attached to homes. Models like the Modine Hot Dawg emphasize silent function, while others may have fans or blowers producing some sound.
6. Safety Features and Clearances
Check for safety certifications, sealed burn systems, and ignition controls. Respect clearance recommendations around the heater to avoid fire hazards.
7. Efficiency and Operating Costs
Higher efficiency ratings (above 80%) mean better fuel economy and cost savings. Infrared heaters often score well in efficiency compared to forced-air units.
Choosing the right garage gas heater depends on balancing these factors with your specific garage size, fuel availability, and heating preferences to maintain a warm and comfortable environment all year round.
