Customer Reviews
Customer Review: “In mid winter our master room stopped putting out heat. We called for service, but they were weeks out so I started looking for heaters and saw a review for DREO. They’re all similar and I chose this one for the safety features. I am super impressed with this one! It works very well!”
Customer Review: “Love this heater – so quiet, small and puts out great heat. 3 settings from low to high and you can put temperature desired. Also oscillates. Remote is great. My husband had purchased a Vornado heater from Lowes that was awful – cheap switches, no remote, more expensive and loud. Returned and got this instead.”

Customer Reviews
Customer Review: “Central heat/ac went out few years ago, so I’ve gotten very familiar with different heating sources and window/portable a/c units. This is one of the best heaters I’ve used, aside from ventless propane—which I’m hesitant to use when I’m not home. My house is a basic brick, rectangle, about 1200 sq ft.”
Customer Review: “Oh boy, we love this little heater. We have it in our small camper, about 20 feet long. It does a great job of heating the camper and the eco mode, where you specify the set temp, works great. One of the best things about this heater is how you can specify how it should move and, it is quiet.”

Frequently Asked Questions
Q: What size space heater do I need for a cold room?
A: For most bedrooms or offices (up to 300 sq ft), a 1500W heater is ideal. Larger rooms may need higher wattage or multiple units. Always check the manufacturer’s room size recommendation.
Q: Are space heaters safe to leave on overnight?
A: Yes—if they have safety features like tip-over protection, overheat shutoff, and ETL certification. All three Dreo models we reviewed meet these standards and are safe for overnight use in ECO mode.
Q: Do space heaters use a lot of electricity?
A: A 1500W heater uses about 1.5 kWh per hour. Using ECO mode or a timer can significantly reduce consumption by only heating when needed.
Q: Can I use a space heater in a bathroom?
A: Only if it’s specifically rated for bathroom use and placed away from water sources. Most indoor space heaters are not designed for damp environments.
Q: What’s the difference between ceramic and oil-filled heaters?
A: Ceramic heaters heat up faster and are more energy-efficient, while oil-filled models retain heat longer after turning off but take longer to warm up. Ceramic is better for quick, targeted warmth.
