I remember one particularly bitter winter in our old house. We had a finished attic that served as my home office, but it was an addition with notoriously poor insulation and no direct line to the central thermostat downstairs. My only weapon against the biting cold was a trusty 1500-watt space heater. The problem? The heater’s built-in thermostat was a joke. It had two settings: “off” and “blast furnace.” I was constantly locked in a frustrating cycle: turn it on, work for 30 minutes until I was sweating, turn it off, and then shiver for an hour until my fingers went numb. My productivity plummeted, and my electricity bill soared. This wasn’t just an inconvenience; it was a constant, comfort-robbing distraction. I needed a way to make my “dumb” heater smart enough to maintain a stable, comfortable temperature without my constant intervention. This search for a simple, effective solution is what leads many people, including myself, to products like a plug-in external thermostat.

What to Consider Before Buying a Plug-In Thermostat
A plug-in thermostat is more than just an item; it’s a key solution for reclaiming control over your personal environment. It empowers you to add thermostatic regulation to any plugin heating or cooling device, from portable space heaters and window air conditioners to greenhouse fans and circulation pumps. The primary benefit is twofold: comfort and efficiency. By automatically switching your appliance on and off to maintain a desired temperature, it prevents the wild temperature swings and energy waste associated with devices that are either always on or require manual operation. This simple device can transform a drafty corner, a chilly bathroom, or an RV into a consistently comfortable space while simultaneously curbing excessive energy consumption.
The ideal customer for this type of product is someone facing a specific temperature control challenge in a localized area. This includes renters who can’t modify their home’s central HVAC, homeowners with rooms that are temperature outliers, RV owners, garage and workshop enthusiasts, or even gardeners managing small greenhouses. It’s for the pragmatist who needs a straightforward, non-permanent solution for a single appliance. Conversely, it might not be suitable for those who need multi-zone control, complex scheduling, or smart home integration. If you’re looking to manage your entire home’s climate system with precision and remote access, a hardwired smart thermostat is a far better investment.
Before investing, consider these crucial points in detail:
- Dimensions & Space: These devices plug directly into a wall outlet, but their physical size can be a surprising issue. Many, like the model we’re reviewing today, have a bulky design that can completely block the second outlet in a standard duplex receptacle. Before buying, consider where you’ll plug it in and whether losing access to the adjacent outlet is an acceptable trade-off.
- Capacity/Performance: This is arguably the most critical factor. You must ensure the thermostat’s maximum wattage rating exceeds that of the appliance you’ll be using. Most standard space heaters run at 1500 watts, so a thermostat rated for 1800-1875 watts provides a safe margin. Also, consider performance in terms of accuracy; analog dials are notoriously imprecise and may require a “trial and error” period to find the setting that corresponds to your desired room temperature.
- Materials & Durability: The housing is typically made of plastic, which should be robust and heat-resistant. Pay close attention to user reports regarding durability. Signs of poor construction, such as rattling internal components, or more serious issues like overheating, melting plastic, or electrical burning smells, are major red flags that indicate a potentially unsafe and unreliable product. Safety certifications like ETL or UL are a must-have baseline.
- Ease of Use & Maintenance: The appeal of a plug-in thermostat is its simplicity. The best models are true “plug-and-play” devices. However, check for clear indicators (e.g., power on/off lights) and intuitive controls. For analog models, readability of the dial is important, though as noted, its accuracy is often a separate issue. Long-term care is minimal, but the device’s lifespan and reliability are paramount, especially if used for critical tasks like preventing pipes from freezing.
Keeping these factors in mind, the EconoHome Adjustable Thermostat for Space Heaters stands out in several areas, particularly its high capacity and simple operation. You can explore its detailed specifications here.

First Impressions: Stripped-Down Simplicity
Unboxing the EconoHome Adjustable Thermostat for Space Heaters is a no-frills affair. It arrives in a simple box containing just the unit and a small user manual. The device itself is a minimalist white rectangular block of plastic, about the size of a large power adapter. The dominant feature is the large, analog jog dial on the front, marked with temperatures ranging from 41°F to 86°F. Below it sits a power switch and a single LED indicator light. It feels lightweight yet solid enough, though it lacks the premium feel of more advanced digital climate controllers.
Our initial inspection immediately brought to light some of the discrepancies noted in online listings. Despite some product details mentioning Wi-Fi or complex control methods, this is unequivocally a simple, analog, plug-in device. There is no screen, no app, and no connectivity. On the back, we found the small, recessed Heat/Cool switch, a feature that promises versatility but has been a point of contention for many users. Plugging it into the wall confirmed another key design characteristic: its width completely obstructs the second outlet. This is a significant design choice that users must be aware of before purchasing.
Key Benefits

- High power rating (15A, 1875W) safely handles most space heaters and AC units.
- Versatile use for both heating and cooling applications (on functional units).
- Provides basic thermostatic control to non-thermostatic appliances, saving energy.
Potential Drawbacks
- Temperature dial is highly inaccurate, requiring significant trial-and-error calibration.
- Bulky design blocks the entire wall outlet.
- Widespread reports of poor quality control and serious safety issues (e.g., melting, failure).
A Deep Dive into the EconoHome Thermostat’s Real-World Performance
A product this simple lives or dies by how well it executes its one core job: turning an appliance on and off to maintain a temperature. To find out, we put the EconoHome Adjustable Thermostat for Space Heaters through extensive testing in a variety of scenarios, from regulating a panel heater in a bedroom to managing a fan in a stuffy workshop. Our findings revealed a device with a straightforward promise but a deeply flawed execution.
Simplicity vs. Practicality: The Setup Experience
In theory, the setup is the pinnacle of user-friendliness. You plug the thermostat into the wall. You plug your heater into the thermostat. You turn the dial to your desired temperature. That’s it. There are no menus, no pairing, no complicated instructions. This is its greatest strength, and for users who are intimidated by technology, it’s a massive selling point. We found this process to be as simple as advertised, and within a minute, we had our 1500W ceramic heater connected and ready to go.
However, this is where the simplicity ends and the practicality begins to crumble. The primary user interface—the temperature dial—is wildly inaccurate. This isn’t a minor calibration issue; it’s a fundamental flaw. In our testing, we placed a separate, reliable digital thermometer in the center of the room to get an objective reading. To achieve an actual room temperature of 68°F, we had to set the thermostat’s dial to approximately 76°F. This experience was mirrored precisely by numerous user reports. One user noted, “Mine is set to 72, which keeps my appropriately sized bedroom at about 66°.” This means the numbers on the dial are, at best, a vague suggestion. The setup process evolves from a 30-second plug-in affair into a multi-hour (or multi-day) process of nudging the dial, waiting, measuring the result, and repeating until you land on a setting that produces the ambient temperature you desire. Once you find that sweet spot, it’s best to take a marker and draw your own line on the device, because the printed numbers are functionally useless.
Temperature Regulation and Consistency: Hitting a Moving Target
Once we completed the lengthy calibration process, we focused on its core function: could it consistently maintain the temperature we’d finally achieved? In this regard, the performance was better, albeit with caveats. The device successfully cycled our space heater on and off to keep the room’s temperature relatively stable. We observed a temperature swing of about 3-4 degrees, which is acceptable for a simple mechanical thermostat. When the room cooled to about 66°F, the relay would engage with an audible “click,” the indicator light would turn green, and the heater would power on. It would then run until the room reached about 70°F, at which point it would click off and the light would turn red.
That audible click is a feature worth mentioning. We found it to be a reassuring confirmation that the device was working. As one user in an RV trailer commented, the click is “about the same noise level as the heater and doesn’t bother me.” However, for a light sleeper using this in a bedroom with a silent panel heater, the sound could potentially be disruptive. While the consistency was adequate for general comfort, the initial inaccuracy of the dial makes it a poor choice for applications requiring precision, such as protecting sensitive plants or preventing pipes from freezing in a space where a few degrees can mean the difference between safety and a burst pipe disaster. You’re putting a lot of faith in a device that struggles with its most basic measurement.
The Elephant in the Room: Overwhelming Safety and Durability Concerns
This brings us to the most critical aspect of our review. While our specific test unit functioned without catastrophic failure during our evaluation period, we cannot in good conscience ignore the alarming volume of user reports detailing serious safety and quality control issues. A product that handles 1875 watts of electricity must be, above all else, safe and reliable. The evidence suggests the EconoHome Adjustable Thermostat for Space Heaters frequently fails this fundamental test.
We encountered numerous accounts of units being dead on arrival, with the indicator light stuck on red and no power passing through to the outlet. Others described units that worked for a few weeks or months before failing completely—a terrifying prospect for someone relying on it to keep pipes from freezing, as one user disastrously discovered. More disturbing are the multiple, credible reports of the device dangerously overheating. One user stated, “Came back after 4 hours to smell strong electrical burn smell,” accompanied by a picture of a melted and scorched unit. Another simply said, “Worked great, then almost caught fire.” We also found reports of internal components coming loose and rattling around inside the casing, indicating shoddy assembly. While the product is ETL listed, which provides a baseline assurance of safety testing, the sheer number of real-world failure reports suggests a significant gap between design certification and manufacturing consistency. This is not a minor flaw; it is a critical risk that any potential buyer must weigh heavily. Given these issues, we found it impossible to trust the device for any unattended or long-term use. For those considering this thermostat, we strongly advise you to carefully review the user feedback regarding its long-term safety before making a decision.
What Other Users Are Saying
Synthesizing feedback from a wide range of users reveals a starkly divided opinion, split between those for whom the product “just works” and a significant portion who have experienced critical failures. On the positive side, many users praise its simplicity and effectiveness for niche applications. One user found it “perfect” for controlling the pump on an outdoor wood boiler, allowing them to easily maintain a consistent 78-80°F in their home. Another successfully used it in an RV, noting that it “easily handles the 1500 W of the heater and doesn’t get warm during operation.” These success stories highlight the thermostat’s value proposition: a cheap, simple controller for non-critical comfort.
However, the negative feedback is severe and cannot be overlooked. One customer detailed how their unit went “dead” after just four months, nearly causing pipes to freeze. An even more alarming account comes from a user who returned after a few hours to a “strong electrical burn smell,” discovering the unit had begun to melt and warning others to “definitely avoid this product!!” Other common complaints reinforce our own findings, with one reviewer stating the temperature on/off is “horribly inaccurate… at least 7-10 degrees off,” and another lamenting that the “huge flaw” is that it covers both outlets. These reports paint a picture of a product with serious quality control and safety issues lurking beneath its simple exterior.
How Does the EconoHome Thermostat Compare to the Alternatives?
The EonoHome Adjustable Thermostat for Space Heaters occupies a very specific niche: portable, plugin, analog temperature control. The alternatives are often in entirely different categories, serving different needs. Understanding these differences is key to choosing the right product.

The Honeywell offers a color touchscreen, Wi-Fi connectivity for remote control via an app, complex scheduling, and precise digital temperature control. It’s for the homeowner looking to upgrade their entire home’s climate system for maximum efficiency and convenience. Someone would choose this over the EconoHome if they need whole-home, programmable, and remote-access control, and are willing to undertake a more involved installation process (including the need for a C-wire).
2. Cadet F Series BTF2W Double Pole Thermostat
- RANGE: This thermostat has a temperature range: 45º - 80ºF (7ºC to 27ºC) with an easy to use large, adjusting twist dial
- COMPATIBLE: This thermostat has been made for Cadet F series electric baseboard heaters only (sold separately)
The Cadet BTF2W is a built-in thermostat designed specifically for hardwired electric baseboard heaters. This is a permanent, integrated solution, not a portable one. It’s a simple, reliable mechanical controller that gets wired directly into the wall and the heating unit. A user would choose the Cadet thermostat if they have electric baseboard heaters and want a clean, permanent, and dedicated controller for that system. It offers no portability and is not a plugin device, placing it in a completely separate category from the EconoHome, which is designed for versatility with any plugin appliance.
3. Honeywell TH115-AF-GA/U Programmable Thermostat with Floor Sensor
- Brand: Honeywell
- Product number: TH115-AF-GA
This Honeywell model is another specialty device, designed for controlling 120/240V radiant floor heating systems. Its key features are a floor temperature sensor and built-in GFCI protection, which are critical for this specific application. It is programmable for energy savings and offers precise digital control over floor temperature. A homeowner installing or upgrading an electric heated floor would choose this product for its specialized safety and performance features. It cannot be used with a standard plugin space heater, making the EconoHome the only viable option among this list for someone needing a portable, universal solution for a standard outlet.
The Final Verdict: A Simple Idea Marred by Unacceptable Risk
The EconoHome Adjustable Thermostat for Space Heaters is a product we desperately wanted to love. It promises a simple, affordable solution to a very common problem. For those who receive a well-manufactured unit and are willing to endure the frustrating calibration process, it can function as a basic “set it and forget it” controller for a space heater or fan in non-critical situations. Its ability to handle high-wattage appliances and its sheer operational simplicity are commendable.
However, the praise must end there. The profound inaccuracy of the temperature dial moves it from “convenient” to “cumbersome.” The bulky design that blocks an entire outlet is a notable inconvenience. But most importantly, the widespread, credible, and severe user reports of complete failure, overheating, and potential fire hazards make it impossible for us to recommend. While any product can have occasional defects, the pattern of failure reported for this device is too significant to ignore. The potential savings in energy or initial purchase price are not worth the risk to property or safety.
If you’ve decided the EconoHome Adjustable Thermostat for Space Heaters is a risk you are willing to take for a simple, low-cost application, you can check its current price and purchase it here. However, we strongly urge buyers to consider alternatives and to never, under any circumstances, leave this device operating while unattended.
