Infrared heaters, also known as IR heaters, use a quartz heating element to directly warm people and objects, rather than heating up the air like a ceramic heater. The heaters stay relatively cool to the touch, making them a safer choice in households with pets or kids.
"The most important things to consider when shopping for an infrared heater are whether it's rated for the size of the space you're trying to heat," says Mallory Micetich, vice president of corporate communications at Angi and an expert in consumer protection and small home living. We've confirmed this after hours of researching and testing popular infrared heaters.
The higher the watt output rating, the more heat you get from the infrared heater. If the heater is the room's primary source of warmth in a room, you’ll want a higher watt rating (closer to 1,500 watts) for bigger rooms. Heaters with a low setting usually allow you to switch between 1,500 and 750 watts and are best suited for smaller spaces.
We rated the heaters for heating performance, design, safety features, and value. We also carefully noted characteristics such as noise output, and the temperature and humidity ratings in the rooms being heated to help you find the best option for your space.

What We Don't Like
Remote instructions could be clearer
If your home doesn't have a built-in fireplace or you want something more functional than a faux fireplace, this charming infrared heater is the next best thing. We've tested the Duraflame stove in our lab and at home, and it earned our top spot as our favorite infrared heater.Its sleek design, comprehensive safety features, and customizable settings for heat and lighting make it an exceptional choice.
It's designed to look like a wood stove, with a flickering flame effect complete with fake logs and embers. During testing, we were impressed by how realistic the glow was able to replicate the appearance and ambiance of a real firebox. Not only does this feature add a touch of elegance to any room, but it also enhances the product's overall aesthetic.
Assembling it was a breeze; all we had to do was screw on the legs. This heater operates at a noise level of only 56 decibels, which is similar to that of a dishwasher, making it a relatively quiet option.
As for the heating, we were thoroughly impressed with how well it worked. With 5,200 BTUs, it can heat spaces of up to 1,000 square feet. It's worth noting that BTUs are used to measure heat output, and the higher the unit, the greater the heating capacity. So, it's safe to say that this heater packs quite a punch and is perfect for those cold winter nights.
The heater has an adjustable digital thermostat and auto-shutoff protection for added safety. The best part is that you can use the space heater with both lighting and heat or just the lighting effect to create a cozy atmosphere all year round. To avoid the hassle of tangled cables, the heater has handy hooks on the back that can corral the cord when you aren't using it.
The heater also has multiple settings for brightness and temperature that can be adjusted using the included remote control. Although we were able to use the remote, we wish the instructions had been written more clearly. Besides all the great features, the heater has also been tested by the Underwriters' Laboratory (UL), which Micetich says is an important consideration.
What An Expert Says
"Both UL and ETL [Electrical Testing Laboratories, also called Intertek] are nationally recognized energy testing standards, and if your heater has one of these certifications, that's a great thing. All in all, this effective infrared heater is an excellent addition to your home that seamlessly blends in with your decor." — Mallory Micetich, Vice President of Corporate Communications at Angi.
How It Performed Long-Term
After putting this space heater through six months of testing, we are still absolutely blown away by how well it heats up any room. One of our favorite features is the ability to control the heat and flame settings independently, which means we can enjoy the cozy glow of the flames without overheating the room.
The timer functionality is also incredibly convenient, as it eliminates any concerns we had about accidentally leaving the heater on. Overall, we highly recommend this heater to anyone who wants the ambiance of a fireplace without any hassle.

What We Like
Wheels make it easy to relocate
Multiple safety features
Unique design
What We Don't Like
Timer only works with remote
If you're in the market for a space heater, don't overlook the importance of portability. If you want to bring warmth to any room easily, heaters with wheels are the perfect solution. This portable, UL-certified heater is designed to heat rooms up to 1,000 square feet, like our best overall pick. We originally tested this box-shape model at home but have since tested it in our lab along with 43 other space heaters.
The unit uses two types of space heating technology to warm up any room effectively. The first is quartz infrared, while the second is PTC (positive temperature coefficient) — a self-regulating feature that adjusts based on the room's air temperature. The heater boasts high and low modes and an eco mode, which uses a mix of high and low to determine the most environmentally sound way to heat the room.
Although the heater works well if you're right next to it, we found that it doesn't warm the room as effectively as we had hoped. We weren't too discouraged as this is a common characteristic of infrared heaters, which emit waves of warmth to heat you and nearby objects directly rather than solely warming the air like electric heaters.
During testing, we found that our body temperature increased by almost 5 degrees when the heater was set on high and 1.4 degrees when it was set on low. A digital control pad on the front of this infrared heater makes it easy to adjust the target temperature within a range of 50 and 86 degrees
The safety features of this heater are impressive, with both tip-over and overheat protection. During our testing, we found that the tip-over protection worked effectively, shutting off the heater immediately. However, it is worth noting that the heater does not turn back on once it is upright again. Additionally, the unit is quite sturdy thanks to its wheels, making it difficult to overturn in most cases.
One potential issue we encountered is that the timer can only be set with the remote, which could be problematic if it is ever lost. We recommend storing it somewhere safely or in a remote organizer. There is also no way to turn on the heater from bed on a chilly morning because you can not use a remote.Despite these shortcomings, we believe this is a solid choice given the handy wheels, reliability, and attractive profile that doesn't look like a tower fan.

What We Like
Not too noisy
Great for smaller spaces
Washable filter
What We Don't Like
Feet seem a bit flimsy
If you are contemplating whether or not to install an electric wall heater, this slim heater, which is ETL certified, gives you the option to mount it on a wall or set it up on the floor, thanks to its removable feet. It's compact and thin, so it doesn't take up much space, making it a great pick for small rooms. During testing, we didn't notice much warmth while using the low setting, however, the high setting definitely kept us toasty (we saw a two-degree increase in body temperature).
While we didn't have the opportunity to mount the heater during testing, we used the heating on the floor with the included feet. Even though we had no issues with the heater tipping over, we noticed the feet weren't the most durable. Like our best overall pick, this heater is not too noisy at just 55 decibels on low. This heater offers convenient features such as a washable filter and a front grill that stays cool to the touch, making it ideal for households with young children.
However, during our lab's tip-over test, we found that although the heat shut off as expected and displayed an error message, the fan continued to run. We also found the included remote a bit small and had to push the buttons several times to get the heater settings to change. Despite this, we value the convenience of being able to control the heater with a remote.
How It Performed Long-Term
After six months of constant use, we found that this heater still meets our standards. We relocated it to a room with poor circulation, and our dogs enjoy lounging in the warmth. The remote control is very convenient, making it easy to turn the heater on and off from a distance. Overall, this is a great option for those seeking a wall-mounted heater that blows warm air downward.

What We Like
Heats up space quickly
Easy to move with carrying handle
Can change brightness levels
What We Don't Like
Griddle becomes extremely hot
Despite looking like a toaster, this space heater can produce up to 5,200 BTUs of heating power from its four quartz heating elements, making it an excellent choice for a large, open floor space. The temperature can be adjusted anywhere from 60 to 99 degrees Fahrenheit throughout its three primary settings (low, auto, and high). It also has a temperature lock and three brightness levels for the display to ensure it won't disturb your sleep at night. During testing, we noted a substantial change in the air being pushed out and the temperature while switching between these levels.
We set the heater at its maximum setting (99 degrees). Although the temperature never rose above 88 degrees Fahrenheit on the thermostat, the room became pretty hot, so we didn't feel it needed to be higher. The heater produced a consistent white noise during our test that was neither loud nor distracting.
It is small and light, making it simple to transport from one place to another; the top handle can be used to move the unit and stow away the accompanying tiny remote control. However, we discovered that the remote only functions within a four-foot range and only when you are directly in front of the heater.
This model, like the others on our recommended list, is loaded with safety features meant to keep you safe while you're using the heater. Overheat protection uses an inside sensor to keep things from becoming too hot, and a child lock function prevents children from changing the temperature.
During our tests, we noticed that the heater's body and sides did not get hot. However, we do not advise using this heater unattended around children or pets because the griddle from which the heat emanates gets extremely hot. Despite this, we think it's a great space heater to use in a larger space or even a garage heater.

Buttons are hard to see when sitting
If you're looking for an outdoor infrared heater to keep you warm, this oscillating heater is perfect for you. It is IP54 certified and has a weatherproof rating, which means it can withstand all weather conditions.We tested this patio heater in our lab and were impressed by how much it heated our bodies. Before turning on the heater, we recorded a core body temperature of 49.8 degrees Fahrenheit.
However, our temperatures quickly rose by 6.5 degrees with the heater on low and by another 6.6 degrees with it on high. When we tested, we only felt the heat on high up to a distance of 3 feet. It's worth mentioning that the outdoor temperature was 30 degrees.
Setting up the heater was incredibly easy. It's a single unit that snaps onto the base with absolute ease. The heater also has a remote and holder, so you'll never have to worry about losing them. We loved the oscillating feature and found that it did not affect the heating capability in the slightest. The heater is 30 inches tall, but it's pretty stable and barely budged during our tip-over test.
The unit's buttons are designed for maximum legibility, with large and tilted buttons that are easy to press with your fingertip. However, we found that they are even more easily readable from a standing position than when sitting. Like most of the heaters on our list, this model also has overheating protection and a timer setting. With four available options, you can confidently select a time and avoid the worry of forgetting to turn off the heater.

This electric heater is certified by ETL and boasts an innovative positive temperature coefficient (PTC) heating element made of copper that never requires replacement. You can choose between high or low mode, and a convenient remote control is included for easy operation.
At nearly 24 pounds, it's a bit of a beast if you need to bring it from one level of your home to another. However, it's worth noting that this electric heater includes a washable lifetime filter, like our best wall-mounted pick, that can be cleaned using warm water and mild dish soap. With 5000 BTUs, this heater is suitable for heating small to large rooms.
It also comes with safety features such as tip-over protection, overheat protection, and auto reboot, which helps it recover in the event of a power outage or surge. The entire exterior stays cool to the touch, making it a nice option for families with young children. All in all, it checks off a lot of boxes when it comes to features and key considerations for infrared heaters.

Final Verdict
We gave the Duraflame 3D Infrared Electric Fireplace Stove our best overall accolade thanks to its adjustable thermostat and brightness, safety features such as auto shutoff, and cozy good looks. If you're looking for something easy to move around, the Dr. Infrared Heater Portable Space Heater has convenient wheels, a funky retro profile, and the bonus of having a slightly lower price than the Duraflame.
Other Options We Tested
LifeSmart LifePro Infrared Tower Space Heater: After putting this heater to the test, we discovered a few flaws. The control panel icons were unclear, and the heater mode button options were too dim. This made it tough when trying to select the right setting. We also noticed that the Eco LED light only comes on when the temperature drops below 68 degrees, which might not be helpful for those who like it warmer. While the oscillating function was great for directing air flow, the heating itself wasn't as strong as we had hoped. We think there's definitely room for improvement in the design and functionality of the heater.
Briza Infrared Electric Patio Heater Indoor/Outdoor Heater: This heater is impressively versatile in terms of design. You can choose to mount it on a wall, ceiling, or tripod that extends up to 7 feet high. However, the heater is top-heavy, so it is important to be careful when placing it near small children and pets. We also weren't really able to feel much warmth unless we were closer than two feet from the heater.
How We Tested the Heaters
We put 23 electric heaters and 43 space heaters to the test in The Lab in Des Moines, Iowa, and in our homes, assessing them on a variety of factors:
- Assembly: Our team was meticulous in assembling each heater, noting the time required to assemble, the tools needed, and the clarity of instructions. We then put each space heater into an outlet fitted with a P3 Kill a Watt meter to determine how much power they actually required.
- Heating Performance: To evaluate heating performance, we utilized two infrared thermometersand monitored changes in the ambient temperature as well as the relative humidity. We took readings after testing each heat setting and again 30 minutes later. We also took note of how each heater affected our core body temperature and how toasty we were.In our most recent tests, we recorded the temperature changes of a chair positioned 4 feet away from the heater and another one that was placed 8 feet away. We also put the thermometers to use by checking the interior and exterior temperatures of the heater from top to bottom and front to back. We measured these same areas of each space heater once they had been switched off for 15 minutes.
- Design: Once we tested all the heat settings, we took a look at the added features. For oscillating heaters, we turned them on to their highest setting and evaluated their range. For heaters with app control options, we assessed how easy it was to connect the heater to Wi-Fi and set up the app and if the in-app controls were user-friendly. For remote-controlled heaters, we not only evaluated its ease of use but also the range of the remote. We tested the remote from a distance of four and eight feet away from the theater.
- Safety Features: Safety is very important to consider when shopping for an infrared heater, so we also conducted a tip-over test by gently nudging the unit over while it was on its lowest setting. We then recorded whether the unit automatically shut off or remained on after 30 seconds.
- Overall Value: After evaluating all of the heaters' features and performance, we compared them to other heaters we have tested, determining if the price is reasonable for the quality of the heater.
After conducting a comprehensive analysis of product scores and insights and extensive research, we have compiled a list of the best infrared heaters. We then put these heaters to the test in our homes across the country, evaluating their long-term performance.
What to Look For in an Infrared Heater
Size
Some IR heaters are designed for tabletops or small spaces (like our best portable heater, the Dr. Infrared Heater Portable Space Heater); others are larger and must be placed on the floor (like our best splurge pick, the EdenPURE CopperSMART Electric Space Heater). It’s always a good idea to measure the location where you plan to put your heater, so you can be sure to buy one with the right dimensions.
Some units can also be mounted on a wall or the ceiling such as our best wall-mounted pick, the Heat Storm Phoenix Infrared Space Heater. Measure those areas, and note the electrical outlet locations.
Safety Features
When buying a space heater, it's worth going above and beyond in terms of safety and testing because these products have a certain amount of risk associated with them—it's almost like when you're buying products for children," says Micetich.
- ETL- and UL-Listed: If your heater of choice has either UL or ETL certification, like our best portable heater, the Dr. Infrared Heater Portable Space Heater, it means it's been subject to rigorous safety tests at an independent laboratory.
- Tip-Over Shutoff: Many heaters come with tip-over shutoff, including our best budget pick, the Comfort Zone Infrared Radiant Tower Space Heater, which means the unit turns off if it's flipped on its side, thus reducing the risk of fire. Some buyers note that certain devices are highly sensitive and power down even when the device is tipped only about 10 degrees.
- Overheat Shutoff: This safety feature causes the device to turn off if it starts to overheat, which could happen if dust or something else (a blanket dropped by a toddler, for example) blocks the airflow. Our favorite pick for large rooms, the Heat Storm Portable Infrared Heater, has this helpful feature.
- Cool-Touch Exterior: A huge benefit of infrared heaters is the outside never becomes overly hot, though you should keep your fingers away from the grill, and watch children carefully at all times when they're around one. "Just because it's cool to the touch doesn't mean the risk isn't there," Micetich says. "But if a kid bumps it or a pet runs into it, it's not going to cause an immediate burn."
- Ingress Protection Code (IPC): This code is expressed as a two-digit number that shows how well a product, such as an outdoor heater, fares when exposed to the elements. The first digit refers to the product's resistance to solids, while the second is its resistance to liquids. Our top pick for an outdoor heater, the Westinghouse Electric Standing Patio Heater, has an IPC of 54, meaning it can withstand dust and sprayed water, but should placed indoors or in a covered area during heavy rainfall.
Noise Level
The sound of a heater becomes important when using a heater for hours on end. Heaters on average produce 60 decibels of sound, which is equivalent to rainfall or a friendly conversation.
All of the options on this list were relatively quiet, but still produced a bit of white noise. Our best overall pick, the Duraflame 3D Infrared Electric Fireplace Stove, operated at 56 decibels, which is comparable to a running dishwasher.
FAQ
How does an infrared heater work?
Unlike a convection heater, which warms the air in a room, an infrared heater uses radiation to directly warm people and objects; the feeling is comparable to being warmed by sunlight. "It's important to know that when you have an infrared heater, you need a clear line of sight between you and it—you can't have something big, like an ottoman [between you], or you're going to heat the ottoman and not feel much," says Micetich. She notes that shoppers might want to consider the heater's aesthetic since it may need prominent placement in the room.
Do infrared heaters use a lot of electricity?
Infrared heaters are more energy efficient than electric space heaters. They still use electricity to run, however, and while your bill might be lower, energy use depends on the size of your machine and how much power it uses. This means some infrared heaters can use as much electricity as conventional heaters.
"Relatively speaking, radiant space heaters are fairly efficient, but any electric heating unit is not the most efficient," says Micetich, who notes that several factors may play a role in your final bill. "It costs approximately 30 cents an hour to run an infrared heater," Micetich adds, "but this also depends on where you live and the unit size. If you're using it as a primary heat source, you're going to need more than one, which of course will require more electricity."
Does an infrared heater heat a room?
Infrared heaters, therefore, do not heat the air in a room the same way conventional space heaters do; nonetheless, they raise the temperature slightly. Many manufacturers give square footage guidelines for specific models. Note that infrared heaters often don't work as well in draftier areas such as screened-in porches, or rooms with vaulted ceilings. "An infrared heater wouldn't be the best choice to heat up a large room," says Micetich, "but they're great for spaces like a small kitchen or bedroom, office, or breakfast nook." That said, you may also find when reading reviews that some models do a good job making a large room feel cozier, despite the manufacturer's recommendations.
Why Trust The Spruce?
