The best type of garage heater is a propane or electric heater, as they provide efficient, powerful heating suitable for large spaces and varying temperatures.
Shivering in your garage while working on projects? Struggling to keep tools warm or prevent pipes from freezing? A chilly workspace kills productivity and comfort.
The right garage heater can transform your space into a year-round haven. In this guide, we’ll compare infrared, forced-air, and electric models, plus share pro tips for installation. For maintenance insights, check our guide on heater upkeep.
Key Takeaways
- Infrared heaters heat objects directly, reducing heat loss in drafty garages
- Forced-air units warm spaces quickly but work best in insulated areas
- Propane models offer portability but require ventilation
- Ceiling-mounted designs save floor space in crowded workshops
Infrared vs. Forced-Air: Which Heater Type Wins?
Infrared heaters emit radiant heat that warms objects and people directly, similar to sunlight. Unlike traditional models that heat the air (which escapes when doors open), infrared maintains warmth on tools, floors, and workbenches. Tests show infrared raises ambient temperatures by 12°F within 30 minutes in 600 sq ft garages.
Forced-air heaters blow heated air through ducts or vents. While they heat spaces faster initially, they lose efficiency in uninsulated areas. The Remington Forced Air Heater with thermostat is ideal for quick warm-ups but consumes more energy long-term.
| Type | Best For | BTU Range |
|---|---|---|
| Infrared | Drafty spaces, spot heating | 5,000–30,000 |
| Forced-Air | Insulated garages, fast warm-up | 10,000–80,000 |
Propane Heaters: Portable But Require Care
Propane models like the Mr. Heater Big Buddy deliver intense heat without electricity—crucial during outages. However, they must be used in well-ventilated areas to prevent carbon monoxide buildup. Always install a CO detector when using fuel-based heaters.
Installation Tips for Maximum Efficiency
Ceiling vs. Wall Mounting
Mounting heaters overhead (like the Comfort Zone Ceiling Mount) keeps them away from tools and vehicles while improving heat distribution. Ensure at least 18 inches of clearance from flammable materials.
Power Requirements
Electric heaters need dedicated circuits—most 240V models require 30-amp breakers. For wiring guidance, see our electric heater installation tutorial.
FAQ
Are garage heaters safe?
Yes, when properly installed. Look for tip-over switches, overheat protection, and certifications from ETL or UL.
How many BTUs do I need?
Calculate garage volume (length × width × height) and multiply by 5 (for insulation) or 10 (uninsulated). Example: A 20’x20’x8’ garage needs 32,000 BTUs if uninsulated.
Can I use a space heater in my garage?
Standard space heaters lack power for garages. Opt for heavy-duty models rated for 500+ sq ft.
Final Recommendation
For most users, infrared heaters offer the best balance of efficiency and comfort. The Briza Infrared tops our list with its 1,500W output and silent operation. Pair it with a smart thermostat for automated climate control.
