Buying Guide
FAQs
What should I look for in a space heater for a 600 sq ft garage?
Prioritize heaters with high BTU ratings (at least 5,000 BTU) or wattage (1,500W or more) to effectively heat the space. Look for safety features like tip-over protection and overheat shut-off, especially in a garage setting. Portability and durability are also key for easy movement and long-term use.
How do electric and propane heaters compare for a garage?
Electric heaters are easier to install and safer indoors but may struggle with very cold temperatures. Propane heaters provide more powerful heat but require proper ventilation to avoid carbon monoxide buildup. Choose based on your garage’s insulation and ventilation options.
Are infrared heaters a good choice for a garage?
Yes, infrared heaters are efficient for garages because they heat objects and people directly rather than the air. They work well in poorly insulated spaces and provide instant warmth. However, they may have a smaller coverage area compared to forced-air heaters.
What safety features are essential for a garage heater?
Tip-over protection and overheat shut-off are critical to prevent accidents in a garage environment. Look for heaters with cool-touch exteriors and sturdy bases to reduce fire risks. Always ensure the heater is rated for garage use and follow manufacturer guidelines.
How much does it cost to run a garage heater?
Running a 1,500W electric heater costs about $0.20 per hour, depending on your electricity rate. Propane heaters can be cheaper to run but require refilling tanks. Consider energy-efficient models to minimize long-term costs.
Can I use a space heater in an uninsulated garage?
Yes, but you’ll need a more powerful heater, like a propane or high-wattage electric model, to compensate for heat loss. Insulating the garage or using a heater with a fan can improve efficiency. Otherwise, expect higher energy costs and slower heating.
What’s the difference between forced-air and radiant heaters?
Forced-air heaters blow warm air to quickly heat large spaces, while radiant heaters emit infrared heat to warm objects directly. Forced-air models are better for whole-room heating, while radiant heaters are ideal for targeted warmth. Choose based on whether you need spot heating or full coverage.
How do I determine the right size heater for my garage?
Calculate the required BTUs by multiplying the square footage (600 sq ft) by the height of the ceiling and then by 10-15 for uninsulated or insulated spaces. For a standard 8-foot ceiling, aim for 5,000-7,200 BTU. Always check the manufacturer’s coverage recommendations.
