FAQ
- What size heater do I need for a 300 sq ft garage?
– A heater delivering 3000W-4000W can be effective in a well-insulated garage of that size, or use multiple units to share the load. - Is a 240V heater necessary for large spaces?
– For very large spaces or frequent cold starts, a 240V unit can provide higher and more stable output, but ensure electrical capacity and outlet availability. - Are infrared heaters safer for outdoor use?
– Infrared heaters are suitable for outdoor use when rated IP-protected and used with appropriate clearance, but always follow manufacturer guidelines. - Do these heaters require special maintenance?

– For large spaces, space heaters are typically supplementary. Consider insulation and building heating needs to avoid over-reliance on portable units. - What safety features should I look for?
– Look for tip-over switches, overheat protection, cool-touch exteriors, and auto shut-off after prolonged use to reduce risk in busy areas.
