Things to Consider Before Buying a Heavy-Duty Electric Garage Heater
1. Wattage and Heating Area
The higher the wattage, the more square footage the heater can cover. A 5,000W heater can warm up to 500–600 sq. ft., while a 10,000W+ model can heat up to 1,500 sq. ft. Choose a heater that matches the size of your space.
2. Mounting Options
Some heaters are designed for wall or ceiling mounting, freeing up valuable floor space. Others are portable and sit on the ground. Decide based on your layout and available space.
3. Voltage & Electrical Requirements
Most heavy-duty units require a 240V connection and professional hardwiring. Make sure your electrical system can support the heater’s amperage draw (some units pull over 60 amps).
4. Thermostat Control
Digital thermostats allow for more accurate temperature settings. Models with ECO mode can help conserve power.
5. Build Quality & Safety
Look for units with steel housings, overheat protection, thermal shutoff, and ETL/UL certification. These features ensure both durability and safety.
6. Noise Level
Fan-forced heaters can be louder than infrared or radiant models. If you’re working in close quarters or around sensitive projects, noise might be a factor.
Frequently Asked Questions (FAQs)
