For years, my garden office has been my sanctuary—a quiet place to think, write, and work. But it had one persistent, frustrating problem: it was always cold. An old, clunky portable heater was my only solution, a noisy beast that devoured floor space and sent my electricity bill soaring. I’d either have to brave the morning chill for 30 minutes while it struggled to warm the room, or leave it on low overnight, wasting energy. This daily battle against the cold made me realize I needed a permanent, smarter, and more efficient solution that could reclaim my space and pre-warm my office before I even stepped inside. This search led me to explore modern wall-mounted heaters, a category where technology has made incredible leaps.

What to Consider Before Buying an Electric Wall Heater
An electric heater is more than just an appliance; it’s a key solution for creating comfort and usability in spaces that your central heating can’t quite reach. Whether it’s a conservatory, a garage workshop, a garden office, or a perpetually chilly bedroom, a good wall-mounted heater provides targeted, efficient warmth without occupying valuable floor space. The primary benefit is transforming these underused, uncomfortable areas into cozy, functional parts of your home, all while offering greater control over your energy consumption by only heating the rooms you’re using.
The ideal customer for this type of product is someone facing a specific “problem spot” in their home. They value modern conveniences like smart home integration, scheduling, and remote control. They likely have a small-to-medium-sized room (up to around 150-200 sq. ft.) that is reasonably well-insulated and want a permanent, sleek heating fixture. On the other hand, a wall heater might not be suitable for those who need to heat a very large, open-plan area or a room with significant drafts and poor insulation. It’s also not for someone who requires a portable solution they can move from room to room; for that, a traditional portable heater or an oil-filled radiator would be a better choice.
Before investing, consider these crucial points in detail:
- Dimensions & Space: A wall heater’s main advantage is being off the floor. Measure your intended wall space carefully, considering both height and width. Also, check the unit’s depth—how far it protrudes from the wall—to ensure it won’t obstruct a walkway or look too bulky. Remember that most models require a small gap behind them for air intake.
- Heating Performance & Wattage: The heat output, measured in watts, determines how effectively the unit can warm your space. A 1500W heater like this Dreo model is a common and effective standard for supplemental heating in most rooms. Look for features like a PTC ceramic heating element, which provides rapid warmth, and an adjustable thermostat for precise temperature control, which is essential for both comfort and energy efficiency.
- Smart Features & Control: Modern heaters have evolved beyond a simple on/off switch. Wi-Fi connectivity, app control, and voice assistant compatibility (like Alexa or Google Assistant) offer incredible convenience. The ability to set schedules, adjust the temperature remotely, and monitor energy usage from your phone is a game-changer for both comfort and cost savings.
- Noise Level & Safety: If the heater is for a bedroom or office, noise level is paramount. Look for models with a low decibel (dB) rating; anything under 40dB is generally considered quiet. Essential safety features include overheat protection, tip-over switches (for portable models), and flame-retardant construction materials. For potential use in bathrooms, an IP rating like IP24, indicating protection against water splashes, is a must.
Making the right choice means finding a heater that not only warms your room effectively but also integrates seamlessly into your lifestyle.

First Impressions: Sleek, Smart, and Surprisingly Simple
Upon unboxing the Dreo Smart Electric Wall Heater, my first thought was how compact and lightweight it was. Weighing just over 6 pounds, it felt incredibly manageable. The design is clean and modern, a simple white cabinet that blends into the wall rather than dominating it. Some users noted it felt a bit “flimsy” out of the box due to its mostly plastic shell, an initial thought I shared. However, that concern vanished once it was securely mounted. The package includes everything needed for installation: screws, wall plugs, and, most impressively, a cardboard mounting template with a small, built-in spirit level. This thoughtful inclusion immediately signaled that Dreo understands its customers, making what could be a tricky DIY job remarkably straightforward. The clear digital display is subtly integrated into the front panel, and the overall aesthetic is one of understated efficiency, a far cry from the industrial look of older heaters.

A Deep Dive into the Dreo Smart Electric Wall Heater’s Performance
A heater’s true worth is measured in the cold light of a winter morning. Over several weeks, I put the Dreo Smart Electric Wall Heater through its paces in my 120 sq. ft. garden office, a space notorious for its morning chill. My goal was to see if it could not only heat the space but do so quietly, efficiently, and intelligently.
Installation and Design: From Box to Wall in Under 15 Minutes
Dreo has absolutely nailed the installation process. The star of the show is the included paper template. It’s not just a piece of paper with hole markings; it has a small, functional spirit level integrated right into it. This simple but brilliant addition eliminates the need to fumble with a separate level while trying to mark your drill holes. You simply tape the template to the wall, use the bubble level to get it perfectly horizontal, and mark your spots. Several users specifically praised this feature, with one calling the fixing instructions “absolutely spot on.” The heater itself is very light, as confirmed by a reviewer who noted it “weighs less than 3 bags of sugar,” meaning it can be safely mounted on most wall types without needing to find a stud. The process was genuinely effortless: drill four holes, insert the wall plugs, screw in the mounting brackets, and hang the heater. The unit doesn’t sit completely flush against the wall; there’s a necessary gap for the rear air intake, which is a key design element for proper airflow. This thoughtful engineering, combined with the incredibly user-friendly installation kit, makes the setup accessible even for a DIY novice.
Heating Power and Efficiency: A Tiny Titan of Warmth
For such a compact unit, the heat output is startlingly effective. The moment you turn it on, the PTC ceramic element and powerful fan, which pushes air at 11.5 ft/s, get to work. There’s no long, agonizing wait for warmth. We found, as did other users, that it could take the chill off a cold room in minutes. One user was amazed that it “heated up a very cold room within 5 minutes,” and my experience was identical. In my garden office, the temperature would climb from a brisk 10°C to a comfortable 20°C in about 15-20 minutes on the highest setting.
The real magic, however, lies in its intelligent operation. The adjustable electronic thermostat, which ranges from 5°C to 35°C (41°F to 95°F), is precise. I set my target temperature to 21°C, and the heater worked diligently to reach it and then switched to a lower power or cycled off completely to maintain it. The ECO mode is particularly brilliant for this. It automatically selects the optimal power level (High or Low) to maintain your set temperature, preventing energy waste. This functionality was praised by users who saw it as a cost-saving feature. As one person noted, “once it’s up to the set temperature on eco mode it just clicks on occasionally.” However, it’s crucial to set realistic expectations. Several reviews confirmed my findings: in a well-insulated space, it’s a champion. But in a drafty extension or poorly insulated conservatory, it will struggle to keep up. It’s a powerful spot heater, not a replacement for central heating in a leaky building. You can find more about its full heating capabilities and specifications online.
The ‘Smart’ Factor: Ultimate Control from Anywhere
The smart functionality is what truly elevates the Dreo Smart Electric Wall Heater from a good heater to a great one. Connecting it to my home Wi-Fi via the Dreo app was seamless and took less than two minutes. The app itself is clean, intuitive, and powerful. From my phone, I could do everything: turn the heater on or off, change between its three modes (High, Low, ECO), set a precise temperature, and create detailed schedules.
This scheduling feature is a game-changer. I programmed the heater to turn on at 7:30 AM every workday. Walking into a pre-warmed office at 8:00 AM, instead of a freezing one, completely transformed my morning routine. This experience was mirrored by another user who loved that they could “program it to heat my garden office before I even get up.” Another reviewer used it for their garden pub, using the app “to heat it before we go down and in no time at all it is a cosy space.” The integration with Alexa was just as easy. A simple “Alexa, set the office heater to 22 degrees” was all it took. This level of remote and voice control adds a layer of convenience that feels genuinely futuristic and makes the heater an integral part of a modern smart home. For those less inclined to use an app, the included remote control handles all the basic functions perfectly.
Near-Silent Operation and Reassuring Safety
For a device intended for bedrooms and offices, noise is a critical factor. Dreo advertises a 28dB noise level, which is exceptionally quiet—equivalent to a whisper. In practice, on the lowest setting or in ECO mode once the room is warm, it’s barely audible. You can feel the warmth, but you can hardly hear it working. This was a standout feature for me during focused work sessions. One user confirmed it’s “extremely quiet,” making it ideal for quiet environments. It’s worth noting, as another reviewer did, that on the highest fan setting, it’s certainly not “whisper quiet,” but the sound is a smooth, unobtrusive hum of moving air, not the grating mechanical noise of older fan heaters.
On the safety front, Dreo has included all the necessary protections. The unit is built from V-0 flame-retardant materials and features built-in overheat protection that will automatically shut it down if it gets too hot. Furthermore, its IP24 waterproof rating means it’s certified safe for use in damp environments like bathrooms, providing protection against splashes of water from any direction. This makes it a versatile and worry-free option for adding warmth to a chilly bathroom on a winter morning, a feature that significantly enhances its value.
What Other Users Are Saying
Across the board, user feedback for the Dreo Smart Electric Wall Heater is overwhelmingly positive, confirming many of our own findings. Many users, like us, were impressed by the combination of its compact size and powerful output. Comments like “Fantastic little heater. Powerful and yet efficient” and “delivers surprisingly strong heat output” are common. The smart features are a recurring highlight, with one person noting, “The App! Plan in a schedule, connects to WiFi and I can check room temperature remotely.”
However, the feedback also provides a balanced view. A few users pointed out its limitations in poorly insulated spaces, a crucial piece of context. One wrote, “in areas like our extension where insulation isn’t great, it struggles a bit to keep the space warm.” Another common, minor critique was the length of the power cord, which at around 1.7 meters, was found to be “slightly short” by some, occasionally necessitating an extension cord for ideal placement. While there was an isolated report of a defective unit making a grinding noise, this appears to be a rare quality control issue rather than a widespread design flaw.
How Does It Compare to the Alternatives?
The Dreo Smart Electric Wall Heater excels in its niche, but it’s important to see how it stacks up against other types of electric heaters.
1. Belaco 11-Fin Oil Filled Radiator Heater 2500W
The Belaco Oil Filled Radiator operates on a completely different principle. Instead of a fan, it uses electricity to heat oil sealed within its fins, which then radiates heat silently into the room. With a higher 2500W output, it’s better suited for providing sustained, background warmth in slightly larger rooms. Its main advantages are its near-silent operation and the lingering heat it provides even after being turned off. However, it’s much slower to heat a room, lacks any smart features, and is a portable, floor-standing unit that takes up significant space. This is a better choice for someone who prioritizes silence and sustained warmth over speed and smart control.
2. Dreo 25 Inch Oscillating Ceramic Heater

- Unbreakable Safety: This room heater for indoor is fully packed to safely warm up your winter. Built with V0 flame retardant material, reinforced plug, 45° tip-over and overheat protection. An...
This is Dreo’s own floor-standing alternative. It shares the same excellent PTC ceramic heating technology for rapid warmth but is designed for portability. Its key advantage is the 70° automatic oscillation, which allows it to distribute heat over a much wider area than the wall heater’s fixed position. It also includes a remote, timer, and multiple safety features. This model is ideal for someone who wants the quick heating of a Dreo ceramic heater but needs the flexibility to move it between rooms or wants to heat a larger living area more evenly, sacrificing the space-saving benefit of a wall mount.
3. Belaco 11 Fin Oil Filled Radiator 2500W
Similar to the other Belaco model, this 11-fin, 2500W oil radiator is a workhorse for steady, quiet heat. It’s built for durability and simplicity, with manual thermostat controls and three heat settings. Users who are not interested in apps or Wi-Fi connectivity and simply want a reliable, traditional heater to maintain a constant temperature in a bedroom or living room would prefer this. It represents a more old-school approach: slower, less “smart,” but incredibly effective for silent, radiant heating and a great option for those who find fan noise distracting, no matter how quiet.
The Final Verdict: Is the Dreo Smart Electric Wall Heater Worth It?
After extensive testing, we can confidently say that the Dreo Smart Electric Wall Heater is an outstanding product that delivers precisely what it promises. It is the perfect solution for anyone looking to solve the “one cold room” problem with a modern, efficient, and intelligent device. Its rapid heating, whisper-quiet operation, and sleek, space-saving design make it a top contender in its category. The true standout feature, however, is the seamless smart integration, which provides a level of convenience and control that genuinely improves your daily comfort.
While it may not be powerful enough to heat a large, poorly insulated space, it’s not designed for that. For its intended purpose—warming bedrooms, home offices, conservatories, and even bathrooms—it excels. If you’re tired of bulky, inefficient heaters and want to step into the future of smart home comfort, this is an investment you won’t regret. For its blend of performance, design, and intelligence, the Dreo Smart Electric Wall Heater gets our highest recommendation.
