Heating and Cooling — FAQ
Can these Dreo heaters actually heat a two-car garage?
No. All models are 1500W, 120V units designed for indoor spaces up to 400 sq ft. A typical two-car garage (500-600 sq ft) requires 5,000-10,000W of 240V heating. For two-car garages, you'd need 2-3 Dreo units on separate circuits, which is impractical. These are best for single-car garages or workshop bays.
Are Dreo indoor heaters safe for garage use?
They include essential safety features—overheat protection, tip-over shutoff, and ETL certification. However, they're not rated for dusty industrial environments. Keep them elevated, maintain 3-foot clearance from flammables, and never use extension cords. The ALCI plug model adds extra protection for damp garage floors.
Why don't these heaters use 240V like real garage heaters?
Dreo specializes in residential indoor heaters. True garage heaters require 240V circuits, permanent mounting, and industrial certifications. These 120V models offer easier installation and portability but sacrifice heating power. They're compromise solutions for hobbyists, not professional mechanics.
How high should I mount a wall heater in my garage?
Mount 6-7 feet high on interior walls, away from garage doors and vehicles. Ensure the bottom clears workbenches by at least 12 inches. Avoid mounting near sprinkler heads or storage shelves. The heater must tilt slightly downward to direct heat toward your work zone, not the ceiling.
Do smart features work in detached garages?
Only if your WiFi signal reaches the garage. Metal garage doors and walls block signals. Test your phone's WiFi at the intended mounting location before buying a smart model. Consider a WiFi extender if signal is weak. Non-smart models are more reliable for detached structures.
Oil-filled radiator vs ceramic fan heater for garage?
Oil radiators provide silent, sustained heat without circulating dust—ideal for woodworking shops. Ceramic heaters heat faster and oscillate for better distribution but blow dust onto projects. Choose oil for all-day occupancy, ceramic for quick warm-ups before short sessions.
