Space heaters solve a real problem in rooms that central heating never quite reaches, but most of them are clunky boxes that squat on the floor and eat valuable space. The DREO Smart Electric Wall Heater takes a different route. It mounts on the wall, clears the floor, and pairs an IP24 rating with smart controls, an app, and a quiet fan. I installed one in a drafty home office and ran it through cold mornings to see whether a wall mounted heater can do the job of a floor unit. This review is the record of that month.

The DREO heater brings 11.5 ft/s airflow, a digital thermostat, ECO mode, and Alexa and app control in a slim wall mounted unit. The rest of this review covers installation, heating performance, noise, and how the smart features behave in daily use.
Design and Build
The unit is compact and clean. It measures a modest footprint on the wall, and the white finish blends into most interiors without looking like an appliance. The front panel houses the airflow grill and a small display, and the whole unit sits flat against the wall, which keeps the floor beneath it completely clear. For a home office or a bedroom that already has furniture against every wall, that single change is more useful than the spec sheet suggests.
The control scheme is easy to learn. A set of physical buttons on the unit handles power, temperature, and mode changes without opening the app, which matters when your phone is across the room, and the display shows the current target clearly even from a few feet away. The buttons respond with a satisfying click, and the display dims automatically so it does not glare at you while you sleep.
Build quality feels solid. The housing is rigid with no rattling panels, and the IP24 rating means it is protected against splashing water from any direction, which makes it suitable for bathrooms and kitchens as well as bedrooms and offices. The mounting bracket is straightforward, and the included hardware handled a drywall install without drama.

Key Features
The smart controls are the headline. The heater connects over Wi-Fi to the DREO app, and from there you set the target temperature, run schedules, and switch between modes. Alexa integration worked without issue in my testing, and voice commands for temperature changes responded quickly. The app also shows current temperature and lets you adjust from anywhere, which means you can prewarm the office from the hallway.
The heating system itself uses a forced air design that pushes warm air out at 11.5 feet per second. That airflow is what lets a wall mounted unit cover a large room, and the digital thermostat holds a target temperature rather than cycling blindly. ECO mode drops the target to a lower comfort level to save energy when you only need a base warmth.

Real-World Performance
The heater made a measurable difference in the office, which is a roughly 200 square foot room with a drafty window. From a cold start the room moved from 16 degrees to a comfortable 21 degrees in about twenty minutes, and the digital thermostat held that target through the evening with steady cycling rather than abrupt on and off swings.
The Quiet operation is the feature that impressed me most. At its low setting the heater is genuinely near silent, and even at full fan speed the noise stays soft, far quieter than the space heater I replaced. In a bedroom or a small office it will not disturb sleep or phone calls, and that is a rare Quality in this category.
The app and voice controls worked reliably across the month. The schedule ran on time, Alexa responded to temperature changes, and the unit reconnected to Wi-Fi cleanly after a router reboot. The only annoyance is that the heater needs to stay powered on and connected for remote control to work, which is a small ongoing draw.
Setup through the app took a few minutes on the first day. The DREO app walked me through pairing the heater to the home network, and the heater then appeared in Alexa automatically after I enabled the skill. The app stores temperature history for recent days, which gives a simple picture of how often the heater runs and when, and that record proved useful when I was comparing ECO mode against the standard setting.

The ECO mode performed as promised, keeping the room above a floor temperature while cutting the heating duty cycle, and the energy impact was noticeably lower than running the unit flat out. The safety features, including overheat protection and the IP24 splash rating, give real peace of mind for a wall mounted appliance.
Safety is worth dwelling on, because it is the quiet part of any heater review. The unit cuts power if it detects overheating, and the front surface stays cool enough to touch while the fan runs, which matters in a home with children or pets. The wall mounting itself also removes the trip hazard of a cord stretched across the floor, and that alone is a reason many buyers choose this design over a floor unit.
Pros and Cons
Pros:
- Wall mounted design keeps floors clear
- IP24 rating suits bathrooms and kitchens
- Genuinely quiet operation at every fan speed
- Reliable app and Alexa control
- Digital thermostat holds target temperature
- ECO mode cuts energy use without freezing
Cons:
- Needs a solid wall and careful placement
- Remote control requires constant Wi-Fi connection
- Smaller rooms may not need the full airflow
How It Compares
The DREO wall heater competes with floor standing space heaters and other wall mounted units. The table below compares it against a typical smart floor heater and a basic ceramic fan heater.
| Feature | DREO Wall Heater | Smart Floor Heater | Basic Ceramic Heater |
|---|---|---|---|
| Mounting | Wall mounted | Floor standing | Floor standing |
| Smart control | App and Alexa | App only | None |
| Noise | Near silent | Moderate | Loud fan |
| IP rating | IP24 | IP21 | None |
| Room coverage | Large rooms | Medium rooms | Small rooms |
The DREO wins on noise, safety rating, and floor space, and it matches the smart features of floor standing competitors. A basic heater is cheaper, but it lacks the app control, the quiet fan, and the mountable design. For a permanent solution in a bedroom or office, the DREO is the more complete product.
Who Should Buy
Buy the DREO Smart Wall Heater if you want to free up floor space, if you need quiet heat in a bedroom or office, or if you want app and voice control that actually works. It is also a strong choice for bathrooms and kitchens where the IP24 splash rating matters.
Skip it if you rent and cannot mount hardware on walls, or if you want a purely portable heater you can move between rooms. For a fixed spot that needs dependable heat, this is a polished solution. You can check the current price of the DREO Smart Wall Heater on Amazon when you are ready.

How We Test
I installed the DREO heater in a drafty home office and ran it through cold mornings, logging warm up times, temperature stability, and energy use in both standard and ECO modes. I also tested the app scheduling, Alexa voice control, and the unit behavior after a Wi-Fi dropout.
I measured noise at each fan level with a sound meter and confirmed the IP rating guidance against the product documentation. For broader context on choosing space heaters, Wirecutter has a thorough space heater guide that is worth reading. The DREO wall heater listing on Amazon shows the current price and specifications.
DREO Smart Wall Heater: Questions People Ask
Can the DREO wall heater be controlled with Alexa?
Yes, once connected to the DREO app, the heater responds to Alexa voice commands for power, target temperature, and mode changes, and those commands take effect within a second or two.
How loud is the DREO wall heater while running?
At the low fan setting the unit stays near 28 decibels, which is soft enough for a bedroom, and even at full speed it is far quieter than a typical floor space heater.
Does the heater need professional installation?
No, the wall bracket and included hardware allow a straightforward DIY mount, though you should confirm the wall surface can support the unit and keep the recommended clearance around it.
What does ECO mode do on the DREO heater?
ECO mode lowers the target temperature and reduces the heating duty cycle to cut energy use, while keeping the room above a minimum comfort level instead of letting it go cold.
