Dreo Smart Wall Heater WH719S Review: a compact wall unit that actually heats like a real heater

I’ve been using this Dreo Smart Wall Heater (WH719S) for a few weeks in a medium-sized bedroom and a bit in a home office, and I’ll be straight: it’s not miracle heating, but it’s a pretty solid wall unit that actually puts out real warmth. I bought it mainly to avoid having a bulky space heater on the floor and to be able to control the heat from my phone and Alexa. On those points, it does what it says.

In day-to-day use, the first thing that stood out is how fast it starts blowing hot air. It’s a PTC ceramic heater, so within a minute or two you actually feel warm air, not just lukewarm airflow. I used it as the main heat for a roughly 180–200 sq ft room, and as a booster in a larger living room. As a primary heater in a small to medium room, it’s fine; in a big open space, it’s more of a helper than a full solution.

The smart side is not just a gimmick. The app control and scheduling are actually useful, especially if you hate walking into a cold room. I’ve set it to warm up the bedroom 30–40 minutes before bedtime and then drop a few degrees overnight. That part works well once you get the hang of the app. Voice control with Alexa also works reliably for basic stuff like on/off and temperature changes.

It’s not perfect though. ECO mode can be a bit annoying with the clicking on/off behavior, and the temperature reading is not always spot on. Also, you still have to respect the usual 1500W heater reality: it won’t magically heat a badly insulated big space. But for what it is—a wall-mounted 1500W smart heater—it gets the job done and feels more convenient than the usual floor heaters I’ve used before.

Price-wise, this sits well above a basic $30–$40 space heater and more in line with higher-end smart heaters or panel heaters. So the real question is: are you paying just for looks, or do the features justify the extra cost? After using it, I’d say the value depends heavily on whether you’ll use the smart control and the wall-mount setup. If you just want a heater to throw under a desk, this is overkill. A cheap one will heat just as much, because 1500W is 1500W.

Where the value makes sense is if you want something more permanent and convenient. Being able to schedule heating, turn it on remotely before you get home, and adjust it by voice is genuinely useful. I used the app a lot more than I expected. Setting up day/night programs, especially for a home office or a bedroom, can help you avoid running it nonstop and might save some electricity over time. The ECO mode is a bit annoying, but even without it, just having precise temp control and timers already helps.

Compared to other heaters I’ve owned (oil-filled radiators, cheap tower heaters, and one older wall unit), this one feels more thought-out. The wall mount frees up floor space, the oscillation spreads the heat better, and the auto-dimming screen makes it more bedroom-friendly. Those are small things, but together they justify paying more than bottom-of-the-barrel prices, at least for me. If you’re just trying to keep a garage warm occasionally and don’t care about apps or looks, you can probably do it cheaper with a basic unit.

So in terms of value: I’d call it good, not mind-blowing. You’re paying for convenience and integration, not raw power. If you’re into smart home stuff, want a cleaner wall-mounted look, and plan to use it every winter, the price makes sense. If you just want cheap heat and don’t care about any of that, there are better budget options and this will feel a bit expensive for what it is.

Design-wise, it’s pretty straightforward: a white wall-mounted bar with a front grille and a small display. It doesn’t scream “industrial heater,” which I appreciated in a bedroom. It’s more like a chunky soundbar than a radiator. If your walls are white or light-colored, it blends in decently. It’s not some fancy decor piece, but it doesn’t look cheap or out of place either. I’d call it clean and functional rather than stylish.

The controls are duplicated in three places: on the unit, on the remote, and in the app. That’s handy because if you misplace the remote (which I did on day two), you’re not stuck. The buttons on the heater are touch-style, and the display shows the set temperature, mode, and Wi‑Fi status. The auto-dimming display is actually one of my favorite details—at night it doesn’t blast light across the room, which is an issue I’ve had with other heaters that keep a bright LED on all the time.

As for the oscillation, it’s vertical, so the louvers push air up and down through a 120° range. In practice, that means it can send hot air toward your feet and higher up in the room instead of just blasting one fixed height. You can set different oscillation ranges or disable it. For a wall unit, this helps a lot because the heater isn’t on the floor; you want that air moving to avoid a hot bubble near the unit and cold spots elsewhere.

On the downside, the design does have some compromises. You need a free piece of wall with enough space around it, and you have to think about where the cord will go. It’s not hardwired; it’s a plug-in unit, so you’ll have a visible cable unless your outlet is directly below. The body itself stays reasonably cool to the touch, which is good for kids and pets, but you still need to respect clearances and not pile stuff under it. Overall, I liked the design: it’s simple, practical, and doesn’t dominate the room, but you do need to plan a bit where to put it.

In terms of comfort, I’d break it into three things: noise, airflow, and how it feels to live with it day and night. Noise first: the fan is noticeable but not intrusive. On low, it’s a soft hum that fades into the background pretty easily. On high, you hear it clearly, but it’s still less annoying than those cheap little box heaters that scream at you. I could work, watch TV, or sleep with it on low or medium without feeling bothered. If you’re insanely sensitive to noise, you’ll notice it, but for most people it’s acceptable.

Airflow is actually one of its strengths. Because it’s on the wall and has vertical oscillation, you don’t get that single hot blast at shin level like with floor units. The heat feels more spread out, especially if you let it oscillate. Standing a few feet away, you feel a steady warm flow, not scorching heat in one spot. I didn’t get that burnt-dust smell you sometimes get with older heaters after the first short burn-in. After one or two uses, the smell went away and then it was just warm air.

For sleep, the auto-dimming display is a big plus. In my bedroom tests, once the lights were off, the screen dimmed enough that it didn’t light up the room. That sounds minor, but if you’ve ever had a heater or AC with a bright blue LED staring at you all night, you know it matters. The main comfort issue at night was, again, ECO mode’s clicking. When it was aggressively cycling, it woke me up once or twice. Switching to a fixed power setting solved that.

Day-to-day, the comfort of not having a heater on the floor is underrated. No tripping over it, no kids kicking it, no pets lying directly on it. The unit’s body stays relatively cool, and the safety features (tip-over isn’t relevant since it’s on the wall, but it has overheat protection) give a bit of peace of mind. Overall, for comfort, I’d say it’s pretty solid: warm air feels good, noise is manageable, and with a couple of settings tweaks, it works fine even in a bedroom.

On build quality, the Dreo doesn’t feel like a flimsy plastic toy. The casing has a decent heft, the grille feels sturdy, and the mounting bracket is not some paper-thin metal. When you tighten it to the wall, the unit doesn’t wobble around like it’s about to fall off. I’ve installed cheaper wall heaters before where you’re scared to touch them too hard; this one gives a better impression. Nothing rattles when the fan is running, which is usually a good sign for durability.

I’ve run it quite a few hours per day on cold days, switching between modes, oscillation, and Wi‑Fi control, and so far no weird behavior: no random shutdowns, no burning smell after the first initial run, and no error messages. The fan starts and stops cleanly, and the oscillation mechanism hasn’t made any grinding noises or stuck in one position. The reusable filter is easy to pull out and clean, which should help keep dust out of the internals over time.

That said, it’s still an electronic device with moving parts and a heating element, so long-term wear is always a question. The main things I’d watch over months or years would be: does the fan start making noise, does the oscillation get loose, and does the ECO mode or thermostat get more erratic. Some users mentioned the clicking and ECO behavior even after updates, so it doesn’t seem like a pure software bug that will magically vanish. But nothing in the physical build screams “this will die in a year”. It feels better built than the bargain-bin heaters I’ve used before.

If you plan to use it daily through winter as a primary heater in a small room, I’d at least clean the filter regularly and avoid blocking airflow. It’s still drawing 1500W at full tilt, so respecting basic heater care matters. From what I’ve seen so far, durability seems decent, but I’d call it “confident but not proven for 5+ years yet.” The build gives me more trust than most cheap space heaters, but I wouldn’t treat it like a permanent hardwired baseboard either.

On pure heating, this thing does what a 1500W heater should. In my roughly 200 sq ft office with decent insulation, it took about 20–30 minutes to bring the room from 64°F to around 70–71°F on high. Once it reached temp, it cycled enough to keep things stable without blasting nonstop. In a bigger 300+ sq ft living room that opens into a hallway, it helped, but you can’t expect it to heat the whole area by itself, which is fair for 1500W. It’s more of a strong booster in that context.

The thermostat accuracy is decent but not perfect. The heater’s reading was usually 1–3°F off compared to a separate thermometer placed across the room. That’s normal for many space heaters, but it matters if you’re picky. You can adjust the ambient temp in the app, which helps a bit, but it doesn’t fully solve the slight mismatch. For comfort, I just set it a degree or two higher than what I actually wanted and it felt about right.

Where performance stumbles a bit is ECO mode. Like some reviewers mentioned, ECO tends to click on and off frequently when the temperature is near the set point. You can hear the relay or internal switching as it jumps between power levels or toggles off and on. It’s not super loud, but in a quiet bedroom at night, the repeated clicking can get annoying. I noticed it more when the room was already near the target temp and the heater was trying to fine-tune it. If you’re a light sleeper, this can be a problem.

My workaround was simple: in the bedroom, I stopped using ECO mode at night and just set it to a fixed low or medium power with a target temp and timer. That cut down the clicking and still kept the room comfortable. During the day in the office, ECO was fine because I didn’t care about the occasional click. So, performance overall is pretty solid: quick warm-up, good airflow, and stable heat. Just don’t expect silent, ultra-precise ECO regulation. It’s good enough, but not flawless.

Out of the box, you get the heater body, a remote, mounting hardware, a drilling template, and the manuals. No weird surprises. The unit itself is about 20 inches wide, 13 inches high, and under 5 inches deep, so it doesn’t stick out like an AC unit. It weighs a bit over 9 pounds, so it’s light enough to handle alone but heavy enough that it doesn’t feel cheap. Power-wise, it’s a standard 120V, 1500W heater pulling about 12.5 amps, so you want it on a decent circuit without a million other things plugged in.

In terms of features, it has three power levels (900W, 1000W, 1500W), an adjustable thermostat from 41°F to 95°F, a 24-hour timer, ECO mode, and 120° vertical oscillation. The oscillation is vertical, not side-to-side, which helps spread heat from low to high in the room. There’s Wi‑Fi control through the Dreo app, plus Alexa and Google Home compatibility. The LED panel auto-dims in low light, which is actually nice at night. Noise-wise, it’s quieter than a typical box fan heater but not silent—you’ll hear the fan, but it’s more of a background whoosh.

I mainly used it in three scenarios: as the main heater in a 200 sq ft office, as supplemental heat in a 300+ sq ft living room, and briefly in a bathroom during cold mornings. In all three, the heater behaved like a real heating appliance, not a toy. In the smaller office, it could hold temp by itself as long as it wasn’t freezing outside. In the bigger room, it made the space more comfortable but didn’t replace central heat. That lines up pretty well with the 200 sq ft primary / 750 sq ft supplemental coverage they claim.

What I like is that it’s clearly designed as a semi-permanent solution. This isn’t a $20 plastic desktop heater you toss under a desk. It mounts to the wall, has a reusable filter, and the design and features feel like something you plan to leave in place for a few winters. Just be aware you’re buying an electric 1500W heater with smart features, not a full-blown heating system. If you go in with that mindset, the overall package makes sense.
