FAQ
- What size heater do I need for a 1,500 sq ft garage?
– A heater in the 7,000–10,000W range is commonly suitable for well-insulated spaces of about 1,000–1,500 sq ft. For faster warm-up, 10,000–15,000W can cover larger or poorly insulated zones. - Do these require professional electrical work?
– Yes. Most units must be hard-wired to a 240 V circuit by a licensed electrician, with proper circuit breakers and wiring in accordance with local codes. - Can I install a ceiling-mounted heater myself?
– Some basic ceiling mounts are possible, but many models require secure mounting, electrical connections, and clearance from combustibles. Follow the manufacturer’s installation instructions. - Is a thermostat essential?
– A thermostat helps maintain a stable temperature, reduces energy use, and prevents overheating. Digital thermostats offer programmable settings for convenience. - Are these heaters safe for garages?
– Yes, when used as directed and with proper clearances, overheat protection, and ETL or equivalent certification, they are designed for garage environments. - What is the difference between wall and ceiling mounting?
– Ceiling mounting saves floor space and distributes heat downward, while wall mounting offers flexibility and easier access for some layouts.
