I Tested And Reviewed 10 Best Indoor Electric Heaters For Large Rooms (2023)

After conducting extensive research and testing various electric space heaters, particularly the PTC/Ceramic type, I have compiled a list of essential factors that I consider crucial in selecting a heater. Based on these criteria, I have found a heater that meets all my requirements.

Firstly, one of the most important factors for me is the noise level of the heater. The heater I have chosen is remarkably quiet, and the advertised decibel rating is accurate.

Secondly, I prioritize a heater that maintains a tight temperature swing, and this unit excels in this aspect. It consistently keeps the desired temperature without significant fluctuations.

Furthermore, it is crucial for the fan to completely stop or turn off when the set temperature is reached. This heater meets this requirement, unlike some units that continue to run between off/on cycles, resulting in cooler air being blown out.

Another essential feature for me is the ability of the heater to retain the set temperature in its memory even after being turned off and then back on. This heater successfully retains the set temperature in its memory, except when unplugged, which is expected and reasonable. However, for those who prioritize memory retention even when unplugged, I recommend considering the Dreo line of heaters.

Moreover, it is important for the display to be readable from a distance. This heater's display is more than acceptable in terms of visibility.

In terms of odor, this unit initially had a minor odor, but it dissipated with regular use. Therefore, it can be considered relatively odor-free.

Controlling the wattage draw is another crucial factor for me. This unit initially draws close to 1700 watts when first turned on in high or in ECO mode with the set temperature 2-3 degrees above the ambient temperature. However, the wattage quickly reduces to just under 1500 watts as the set temperature is reached. In low mode, it draws 900 – 950 watts, which is ideal for my needs.

Additionally, the remote control's operation depends on the transmit/receive field of the heater. In this regard, this heater has a wide transmit/receive field, ensuring efficient remote control functionality.

Furthermore, heating performance is a key consideration, and the Sunnote heater excels in this aspect as well. It provides effective heating, particularly in a closed or mostly closed off space. However, it is important to note that the effectiveness of 120 volt electric space heaters is greatly reduced or nullified when there is even one open doorway. Therefore, it is recommended to use this heater in a completely closed or mostly closed off space. In my case, I use it in my 14' x 21' closed off family room, and it functions well, even as a primary heat source with outside temperatures as low as 20 degrees. However, during windy and colder conditions, its effectiveness diminishes. It is important to note that these units are not intended to be used as the sole primary heat source but rather as a secondary one. Personally, I set my forced air heating system to 62 degrees, close off my family room, and the Sunnote heater performs admirably.

It is worth mentioning that this unit offers timer features, although I haven't utilized them yet. The timer can be set to turn off after a period of up to 24 hours, or it can be set to turn on after a specific time interval. This feature can be highly beneficial for many users.

Another noteworthy aspect is the 15-second countdown when turning off or when the set temperature is reached. Most heaters typically have a 30-second countdown for heating element cool down, which can result in a cold air blast for the last 10 – 15 seconds. Therefore, the shorter 15-second countdown provided by this heater is greatly appreciated.

As a side note, I compared the wattage draw of this heater to that of my forced air gas furnace. The furnace's motor draws around 8.9 amps when running, which equates to approximately +/- 1030 watts on a 120 volt circuit. Once my area is adequately warmed up, I will be using the Sunnote heater on low, which consumes 900 – 950 watts. Given the skyrocketing natural gas prices in Michigan, I believe this heater can help me save a few dollars.

The heater in question is highly effective in generating heat, making it suitable for use in smaller rooms. It is easy to operate, with a simple on/off switch and adjustable heat levels. The isolation feature ensures that heat is evenly distributed throughout the room. Additionally, the timer feature allows for automatic shut-off based on the user's preference.

One notable aspect of this heater is its portability, thanks to the built-in handle. This feature makes it convenient to transport from one room to another. Furthermore, the auto shut-off feature ensures safety by immediately turning off the unit when it falls or gets bumped.

The inclusion of a remote control adds to the convenience of using this heater. However, initially, finding a storage space for the remote may seem challenging. Fortunately, there is a designated storage area located at the back of the unit, near the handle, making it easy to keep the remote secure and accessible.

For those who enjoy camping or traveling in a trailer, this heater is a fantastic addition. It provides an efficient alternative to a gas furnace and effectively combats the chill on cold mornings. Overall, this heater receives high praise for its quick heating capabilities and user-friendly controls.

Another user highlights the suitability of this heater for multi-level homes. With no individual room thermostats, it becomes wasteful and costly to heat the entire house. However, this heater allows for targeted heating, making it possible to keep occupied rooms warm while maintaining a lower HVAC thermostat setting.

The ECO mode mimics the functionality of a home thermostat, automatically turning off the heater when the desired temperature is reached. Additionally, the fan-only function provides a cooling option. The oscillating feature helps distribute heat evenly throughout the room, while the tip-over and auto shut-off functions ensure safety.

The timer is easy to set, and the heater has a stable base with a built-in handle for ease of movement. The remote control mirrors the functions and icons of the control panel on the unit itself, making it convenient to operate.

In terms of heating capabilities, this heater performs exceptionally well, quickly and effectively warming up the space. After shutting off, a 30-second LED timer initiates to cool the unit down before powering off completely.

To maintain safety, it is recommended to unplug the heater when not in use or when away from home. Additionally, periodically vacuuming the air inlet vents and front heater screen helps eliminate dust accumulation, reducing the risk of fire.

The Portable Heater with Humidifier is an excellent choice for those in need of a compact and efficient heating solution. Despite its small size, this heater packs a punch when it comes to generating heat. It quickly warms up the room, ensuring a comfortable and cozy environment in no time.

One of the standout features of this heater is the inclusion of a built-in humidifier. This innovative addition helps to combat dry air, ensuring a healthier and more comfortable living space. The fire light only activates in humidifier mode, adding a visually appealing element to the heater.

The rotation function of this heater allows for even distribution of heat throughout the room. This eliminates any cold spots and ensures that every corner of the space is kept warm. Additionally, this heater operates quietly, so you won't be disturbed by any loud noises while enjoying its warmth.

The convenience of the remote control cannot be understated. With just a few clicks, you can easily adjust the temperature from the comfort of your sofa. This not only saves you the hassle of constantly getting up to make temperature changes but also helps to save energy by allowing you to heat only the specific room you're in, rather than the entire house.

In terms of design, this heater is sleek and attractive. It seamlessly blends into any room decor, making it a stylish addition to your living space. Furthermore, its lightweight nature makes it easy to move around, allowing you to enjoy its warmth wherever you go.

I am currently living in a 28-foot RV or travel trailer and I have been pleasantly surprised by the performance of this heater. Despite the cold weather outside with about 32 degrees, my trailer maintains a comfortable room temperature of 60°. I have taken measures to insulate my trailer further by covering the single pane windows with insulated styrofoam, similar to the material used on roll-up garage doors. Additionally, my trailer comes with the Northwest package, which provides some insulation, but it is not enough to keep the interior temperature above freezing without the use of a heater.

I have been using a single heater on high, which periodically turns on and off to maintain the warmth in the room. This heater has been effective in compensating for the use of propane, which can be expensive and affects my SSI budget. I want to address the issue of overheated wall plugs that some users have experienced. In my experience, this is usually caused by loose-fitting wall plugs that are overused or by running the heater continuously at a high temperature. However, by allowing the heater to shut off occasionally, I have not encountered any problems with overheating.

I am so pleased with the performance of this heater that I have decided to purchase a second one. My plan is to place it in the front half of the trailer and run both heaters on low. With this setup, I anticipate being able to maintain a comfortable temperature of around 70 degrees throughout the winter. The addition of the second heater has already proven to be effective, as I woke up this morning to a temperature of 61 degrees indoors while it was only 12 degrees outside.

I highly recommend this heater for anyone in a similar situation, living in a trailer or RV. With some preparation and proper insulation, these heaters work exceptionally well. It's important to note that the heating capacity of the heater should not be exceeded based on the square footage of the room. If the heater is designed for a thousand square feet, it will not effectively heat a space larger than that.

In a recent update, I wanted to mention that I have tested the heaters in even colder temperatures. With the outside temperature dropping to three degrees, I have kept the interior temperature between 65 and 67 degrees by running two heaters on low or eco mode. This approach has allowed me to conserve propane and rely more on electricity, which is cheaper in my area compared to the high cost of propane. I used to go through four 30-pound propane bottles in a month, but with these heaters, I have only used three bottles in two months.

The heaters have been performing admirably during this major storm, with temperatures reaching as low as 12 degrees below zero. I have only needed to turn off the heaters briefly and rely on a propane heater to supplement the heat. The heaters have been running at 68 degrees, maintaining a comfortable temperature in the trailer.

I have been using the Dreo space heater for some time now and I must say that it has been incredibly efficient and powerful. In the past, my wife and I have had similar-sized space heaters with oscillation, but we always noticed that it took a long time for the room to reach a comfortable temperature, especially when there was a cold draft. However, with the Dreo heater, this is not an issue.

One of the standout features of this heater is how quickly it heats up the room. In no time at all, our 20x35ft room is back to a nice and comfortable temperature. Additionally, the LED display allows us to easily see the temperature it is set to, without being too bright when all the lights are off.

The remote control that comes with the heater is also a great convenience. It is especially useful when we are in bed and don't want to get up in the cold to turn on the unit. Furthermore, the ability to set the desired temperature and have the heater automatically turn on and off to maintain that temperature is a feature that I find both useful and energy-saving.

While there are many positives about this heater, there are a couple of minor drawbacks. The manual could provide clearer directions, especially for more tech-savvy users. Additionally, the beeping sound when touching the buttons can be a bit annoying, as it alerts everyone in the vicinity that you are adjusting the heater.

One other small inconvenience is that the countdown timer is set to 15 seconds. When leaving the house, I prefer to quickly unplug all space heaters for peace of mind. However, having to wait 15 seconds has caused me to forget to unplug the unit on a few occasions.

I recently purchased this small heater and I must say, it exceeded my expectations. The heat output is impressive, as my husband could feel the warmth even from the other side of the couch. It's perfect for those cooler fall days when you don't want to turn on the central heating just yet.

One of the standout features of this heater is the remote control and timer. I love the convenience of being able to adjust the settings from a distance, and the timer function allows me to set it to turn off automatically after a certain amount of time. This is especially handy when using it in my kids' room, as I can ensure their safety and prevent any accidental burns.

Speaking of safety, this heater is designed with child safety in mind. The exterior stays cool to the touch, so there's no risk of little hands getting burned. This gives me peace of mind knowing that my kids can enjoy the warmth without any danger.

In terms of size, this heater hits the sweet spot. It's not too big and not too small, making it easy to place in any room. I personally use it in my kids' room when the temperature drops, and it provides them with that extra warmth they need. The fact that it requires no set up is a bonus, as I can start using it right away.

The sleek design adds a touch of elegance to the room, and the overall build quality is excellent. It's sturdy and durable, ensuring that it will last for years to come. Additionally, the heat output is impressive, providing ample warmth even on the coldest of nights.

I particularly appreciate the ability to set the desired temperature. This allows me to customize the heat level to my liking, ensuring maximum comfort. The eco mode is also a great feature, as it helps to conserve energy while still providing sufficient warmth.

I am giving this space heater a 4-star rating because while it does what it claims to do, there are some features that could be improved. Let's start with the positives. The heater has a sleek and slender design that is aesthetically pleasing. It operates quietly and the oscillation feature works well without causing any disturbance. The remote control, although it does not come with batteries, functions perfectly once a battery is installed. The heater offers two heat levels and the option to use only the fan. Additionally, it has a temperature selection feature that allows you to set the desired temperature in increments of 5 degrees. It also includes a 12-hour timer, which is a useful feature.

However, there are a few drawbacks in my opinion. One of them is the inability to set the temperature to a precise degree. It only allows for selection in increments of 5 degrees, which may not be ideal for some users. Another downside is that the heater does not display the current room temperature. While this information can be obtained from other thermometers, it would have been more convenient to have it displayed on the heater itself. The display also turns off automatically, which may not be preferred by some users who would like to keep it on. Furthermore, considering the additional features that other heaters offer at a similar price point, this heater seems slightly overpriced.

I recently purchased this heater for my bedroom, which measures 12.5ft x 10ft, and I am extremely satisfied with its performance. Within the first hour of using it on full blast, it effectively warmed up my chilly room from 55°F to a comfortable 75°F. The safety features of this heater work flawlessly, and the instructions provided are clear and direct, making it easy to set the temperature to the desired level. I initially thought that I would have to manually turn it off and on, but to my surprise, the min and max dial actually functions as a temperature setting, automatically turning off the heater once the room reaches the set temperature.

Although I did encounter a cosmetic issue on the top of the heater, it does not affect its functionality in any way. Additionally, while the heater does emit some noise, it is not overly loud and is actually quieter than an air conditioner.

In fact, when our furnace malfunctioned in September 2022, we purchased two of these heaters to serve as our sole source of heat in the living room and bedroom. Despite day highs of 40-45°F and overnight lows of 15-23°F, these heaters have been able to keep our rooms comfortably warm. We typically set them to full power during the day and switch to low power at night while we sleep. They have been running constantly without any issues of overheating. By closing off unused rooms and using the heaters strategically, we have been able to maintain a comfortable temperature in the living room where we spend most of our time. It's been nearly four months now, and we are pleasantly surprised at how comfortable and cost-effective this solution has been. Our heating bill has noticeably decreased since using these heaters. Additionally, we invested in a transparent insulated door curtain to separate the kitchen, which is typically cold, and the difference it has made is remarkable. We are confident that we could continue living this way for an extended period if necessary.

I purchased this heater on sale last year, and even though I have only used it a few times this year in March, I am highly satisfied with its performance. It quickly warms up the room and maintains the temperature for an extended period. The compact size makes it easy to store and put away. It is perfect for mid-sized rooms and is still effective in larger rooms, although it may take slightly longer to warm up. One of the standout features is its energy efficiency, which has resulted in savings on my electricity bill. The heater has three heat levels, and it automatically controls the temperature to prevent overheating. It also has a security button underneath that ensures it turns off if moved while connected unless it is placed on a stable surface. I highly recommend this heater due to its affordable price, quick heating capabilities, and energy-saving features. Switching to this heater instead of using the house's AC has been a great decision, and I am amazed by its performance so far.
