Most Space Heaters Oscillate Side-to-Side. This Dreo Moves Air Upward for Better Coverage.

3 min readThe Dreo Whole Room space heater oscillates both vertically and horizontally, providing greater heating range than most other options.You can also set specific temperatures, and the device will automatically slow down and shut off once the target temperature is reached before turning back on if the temperature lowers. The child lock, tip-over protection, and safety plug ensure that the space heater won’t cause any injury or start fires. It’s been a bit chilly as the cold weather has begun to set in. In that chilliness, I’ve broken out the cable-knit sweaters and undershirts, but I can’t very well type in gloves. In order to beat the freeze in the cavernously large bullpen with high ceilings and large windows that is our office, I needed a space heater built for the moment. That space heater is the Dreo Whole Room.The Dreo Whole Room space heater oscillates both horizontally and vertically to cover larger areas of space and better distribute heat throughout a room. At the same time, the device is also extremely powerful, blasting heat at three different temperature levels and fan speeds. Particularly for drafty rooms or larger spaces, this is a space heater that not only got my attention but helped get my blood flowing.I loved the Dreo both for quick, on-demand heat as well as for more sustained use over several hours throughout the day. Even in the drafty office, there was a notable difference in temperature almost immediately, and it spread well beyond just my desk when oscillating.ProsOscillates horizontally and verticallyCustomizable temperature settingConsChild lock might need to be a few seconds longerKey SpecsTypeCeramicDimensions11.02 x 7.09 x 12.4 in.Weight6.5 lbHeat Output1,500 WCoverageUp to 269 sq. ft.The Body Rotates in Two DirectionsThe most notable feature on the Dreo Whole Room Heater is the dual oscillation. With both horizontal and vertical oscillation, the space heater is capable of spreading heat in more directions and bringing the temperature of a space up more holistically. This design choice prevents cold spots in a room and provides a more overall warmth so you don’t have to be in direct line of the heater in order to feel its effects.In my own use, the feeling is noticeable. When left on and oscillating for a few minutes in a side room in our office, I walked back into a noticeable shift in temperature. The room was nearly as warm in the far corners of the space as it was within a three-foot radius around the heater.The Multiple Heating Modes Add to Its ValueWhile the oscillation is great for heating up full rooms, there’s still a lot of additional customization available to tinker with. The space heater comes with three different heat levels as well as three fan speeds so you can choose the intensity and strength of the air. While this is great for short bursts of time, I preferred using the temperature setting.Tom PriceThe space heater has touch screen controls built onto the frame.This setting allowed me to choose a specific temperature, and the Dreo would automatically run, slowing down as it neared it, and occasionally turning back on to maintain it. If you expect to use the space heater for extended periods of time, this mode makes it easier to both not overheat and save a bit of energy. That said, the Eco mode is your best bet for cutting down on energy costs.The Heater Has Robust Safety FeaturesOnce I know that the heating power is powerful enough to be worth the money, the next concern is always safety (despite it probably deserving to be first). On this front, the Dreo Whole Room Heater is a solid choice.The space heater not only has tip-over protection and a safety plug but also automatically shuts off if overheated and has a three-second child lock to prevent them from accidentally switching settings inadvertently. My only real issue with the child lock is that the three-second time might not be enough time to prevent a kid from unlocking the features and making changes.Final ThoughtsAs far as a space heater goes, I really only want to make sure it heats well and is safe to use. On those fronts, the Dreo Whole Room Space Heater gets the job done.However, the Dreo goes far beyond what’s expected. The dual oscillation helps warm up larger spaces with greater speed and efficiency, and the safety features make me feel comfortable leaving it on when I’m out of the room for periods of time.If you have larger rooms you want to warm up without turning on your central heating, or simply want to get a fuller warmth as opposed to an incredibly localized one, the Dreo Whole Room is a good horse to back.Shop the Dreo Whole Room Space HeaterOther Space Heaters We RecommendTom Price is a reviews editor for Popular Mechanics while also contributing to Runner's World, Best Products, and Bicycling.
