Why You Need a Garage Heater
A garage heater is essential for maintaining a comfortable workspace, protecting your tools, and preventing freezing temperatures from affecting your vehicle. Choosing the right garage heater depends on several factors, including garage size, insulation, fuel type, and safety features. The right garage heater will efficiently warm your space while keeping energy costs manageable.

Factors to Consider When Choosing a Garage Heater
1. Garage Size and Heating Capacity
The first step in selecting a garage heater is determining your garage size. A heater’s power is measured in BTUs (British Thermal Units) or watts. Larger garages require higher BTU output, while smaller garages can be warmed efficiently with a lower BTU garage heater.

1-Car Garage (150-300 sq. ft.) – A garage heater with 4,000 to 9,000 BTUs or 1,500 watts is sufficient.
2-Car Garage (300-600 sq. ft.) – A garage heater with 12,000 to 20,000 BTUs or 3,000-5,000 watts is ideal.
3-Car Garage (600+ sq. ft.) – A garage heater with 30,000+ BTUs or 6,000+ watts provides optimal warmth.
2. Types of Garage Heaters
Choosing the right garage heater also depends on the type of heating technology and fuel source.

Electric Garage Heaters
Electric garage heaters are easy to install and require no fuel storage. They provide clean, consistent heat and come in portable, wall-mounted, or ceiling-mounted designs. These garage heaters are ideal for well-insulated garages.

Propane Garage Heaters
A propane garage heater offers high BTU output and portability, making it great for garages without electrical access. However, proper ventilation is required to prevent carbon monoxide buildup.

Natural Gas Garage Heaters
For long-term heating, a natural gas garage heater is a cost-effective solution. These heaters connect to an existing gas line and provide powerful, steady heat, making them ideal for large garages.

Infrared Garage Heaters
Infrared garage heaters use radiant heat to warm objects instead of air. This type of garage heater is energy-efficient and works best in drafty garages where maintaining air temperature is challenging.

3. Installation and Mounting Options
Depending on your space, you may need a portable or mounted garage heater.

Portable Garage Heaters – Best for small garages or temporary heating needs. Easy to move and store.
Wall-Mounted Garage Heaters – Save floor space and provide consistent heating in a fixed area. For further details, visit: https://tranecanadamidwest.com/
Ceiling-Mounted Garage Heaters – Ideal for large garages, offering widespread heat distribution without taking up workspace.
4. Safety Features
Safety is crucial when selecting a garage heater. Look for these features to prevent accidents:

Overheat Protection – Automatically shuts off the garage heater if it gets too hot.
Tip-Over Shutoff – Turns off the heater if knocked over (essential for portable models).
Oxygen Depletion Sensor (ODS) – Detects low oxygen levels and shuts off propane or gas garage heaters.
Cool-to-Touch Exterior – Prevents burns when touching the garage heater.
5. Energy Efficiency and Cost
Energy-efficient garage heaters reduce operating costs. Look for:

Adjustable Thermostats – Helps maintain a steady temperature.
Eco Modes – Lowers energy consumption when heating is not needed at full power.
Timer Functions – Allows automatic shutoff to prevent unnecessary use.
6. Climate and Insulation
If your garage is poorly insulated, a high-BTU garage heater may be necessary. Well-insulated garages retain heat better, allowing a lower BTU garage heater to work efficiently. Consider adding insulation to your garage walls and doors to enhance heater performance.
