I Tested Dozens of Space Heaters. These Are the Best in 2025


Frequently Asked Questions

Are Large Heaters More Powerful Than Small Ones?

Nope! It may seem counterintuitive, but large heaters don’t necessarily heat any better than small ones.

Whatever their physical size, most space heaters in the US and Canada deliver about the same amount of heat. Space heaters top out at 1,500 watts, which is the highest safe operating load for a 15-amp household circuit. And aside from some low-power personal heaters here and there, most space heaters you’ll find on the market are 1,500-watt heaters.

What’s more, electric space heaters are all pretty much 100 percent efficient in converting that electricity to heat. Whether directly or indirectly, nearly all of that energy will eventually become heat.

So if space heaters are the same power and the same efficiency, why are some 1,500-watt heaters advertised for small rooms and some for large rooms? This likely has as much to do with marketing as science. Pretty much every ceramic, electric-coil, or PTC heater has about the same amount of juice and thus the same ability to heat a room … at least eventually.

What differs among heaters is how and where the heat gets distributed and how fast. All other things being equal, the efficacy of a heater is mostly about whether it puts the heat where you want it to go.

What Are the Different Types of Space Heaters?

Basically all electric space heaters do the same thing: They take electricity off the grid, usually 1,500 watts of it if you’re in the United States, and turn that power into heat.

The vast majority of space heaters, including ceramic heaters and PTC heaters, are electric resistance heaters. This means they run an electrical current through something that creates resistance: maybe an electric coil or maybe a specially designed ceramic. This quickly turns electricity into heat.

Most space heaters use a fan to disperse this heat out into the world, where we all live. These forced-air convection heaters tend to be the fastest at quickly raising the temperature of the surrounding air. The air then heats you. And so while this variety heats quickly, it can take quite a bit of electricity to heat up a whole room.

Oil-filled radiators, in contrast, heat up oil that circulates inside the device, which then emits heat to the surrounding room. These tend to heat up slower but offer even and lasting heat and are very quiet. These radiators operate on the same principle as steam radiators in buildings with a boiler room. And just like steam radiators, they can get really, really hot to the touch.

Radiant heaters, such as infrared heaters, operate much like the sun or a campfire: Rather than heat the air, they heat objects or people directly by radiating energy toward them. Infrared devices heat the air only indirectly, via the objects it heats— much the same way the sun’s heat radiates off baking city streets. The glow is immediately palpable as warmth, but you’ll need to be in the path of the radiation to feel it, and the thermometer might not immediately register the warmth you perceive. Infrared heaters tend to be best at making an individual in front of the heater feel a little warmer without using a lot of energy, making them a more common decision in large and lofty spaces or outside on a patio.

Though they deliver heat differently, both infrared and oil-filled heaters are subject to the same wattage limitations, and have about the same efficiency, as electrical resistance heaters.

The same cannot be said for heat pumps, a newer technology that’s expected to provide the next generation of household heat. Heat pumps don’t use energy to create heat. Instead, they move heat energy from one place to another. Accordingly, they require far less energy than other forms of heater. But household systems cost thousands to install. And while more affordable window and portable heat pumps are ramping up, they’re not yet broadly available.

Yes, but also definitely no.

Space heaters are much safer than they used to be. Modern space heaters are heavily regulated, especially regarding exposed heating elements and automatic shut-off switches to prevent overheating. But all heating devices require caution, and so do all devices that pull a lot of energy over long periods.

The vast majority of residential heating fires start with actual fire—specifically in fireplaces and fuel burners. But space heaters accounted for more than a thousand fires in the US each year from 2017 to 2019, according to the US Fire Administration. Though this accounted for just 3 percent of heating fires overall, these led to more than 40 percent of fatalities, in part because portable heaters tend to be placed precisely where people are and because the resulting fires are far more likely to be unconfined.

So treat your space heater with the caution and wild skepticism that it deserves. See WIRED’s Guide to Space Heater Safety for a full rundown about how not to start fires or cause othr hazards. Our guide follows recommendations from federal experts at the the USFA and the Consumer Product Safety Commission (CPSC), as well as the Association of Home Appliance Manufacturers (AHAM).

But for the short version:

Don’t leave a space heater unattended. “Unattended” includes sleeping, y’all! Might we suggest a wonderful down comforter instead? When possible, safety experts also recommend you don’t leave a portable heater running unattended in a room with a baby, nor a person with mobility issues. The risk isn’t just fire but hyperthermia.

Plug your heater directly into the outlet. Don’t use extension cords or power strips with space heaters, lest you build up too much electrical load and risk a fire.

Don’t plug another appliance into the same outlet or circuit as the space heater.

Place a space heater only on the floor, on a level surface. Heat rises. You don’t need to prop up a heater on an unstable chair or table.

Keep your heater at least 3 feet from flammable objects. This includes bedding, drapes, furniture, clothes, papers, books. All of that.

Keep space heaters away from water and dampness, whether in bathrooms or in moist basements prone to dripping or flooding.

Read the manual. Manufacturers have good advice.

How We Tested and What We Tested

When it comes to testing space heaters, there are a few main questions: How safe is it? How loud is it? How quickly and evenly can it heat a room?

During intensive testing of dozens of space heaters, I lived for weeks in a home with the thermostat set to a chilly 65 degrees Fahrenheit.

I tested how well and quickly each device heated a medium-size room (14 by 14 feet), and also how well it heated a small seating area in a larger, open-format space. To test each heater’s thermostat and also measure the evenness of heating, I placed thermometers at three or more locations in each room, including behind the heater.

I tested the loudness of each device with a decibel meter at 3 feet away and verified power usage with a wattmeter. To see whether the heater’s exhaust put out painful levels of heat, I used an infrared thermometer to gauge precise surface temperatures. When in doubt, I put my own fingers on the line.

Finally, I tested safety features and basic durability. I looked at independent safety certifications, of course. But I also rudely knocked over each device to verify how the device’s tip-over protections functioned, if at all, and verified that the device started working again when set back on its feet.

To test overheat protection, I smothered each device with an old sheet to see whether the device shut itself off or whether it adjusted its power output to keep internal temperature low. After the device shut itseld off, I then checked how soon it could turn back on, if it ever did. (Some heaters gave up, in permanent complaint!)

If any device fails the tip-over or overheat tests, we don’t recommend it. If it’s significantly louder than 50 decibels at 3 feet, we don’t recommend it. If the heater breaks during routine operation, we don’t recommend it. Maddening rattles and squeaks are also disqualifying.

We keep on testing our favorites through the cold season and beyond, to see how they hold up over time. And, of course, we continually subject more heaters to our testing regimen to see if other devices can oust our current faves.

More Space Heaters I Recommend

Vornado AVH10 for $100: Vornado has an unholy variety of models that look quite similar but have different levels of loudness and different feature sets. Some are built in America, some in China. In general, the models I’ve liked best are the ones that advertise “vortex action,” a fancy name for spinning a fan into a spiral grate oriented opposite to the action of the fan. This leads to a mostly quiet and nigh-undetectable column of warm air, directed out to the back of the room, where it scatters. The TAVH10, which is basically this model but with a timer and remote, is my current favorite, though if you need neither, you can save $30 and get this.

Vornado MVH+ for $75 and Vornado VH240+ for $70: These two devices are very nearly the same device. And the previous year’s non-digital MVH was my favorite model before getting displaced by a couple newer models of Dreo and Vornado. It remains among the most silent, the most even in its heat, and among the most reasonably priced. This said, the TAV10 got a little quieter and the MVH got a little louder, and the addition of a remote and a timer makes it more attractive. This said, there are reasons to favor an analog device. Because they’re analog, the MVH and VH240 can also be regulated by a temperature-controlled power outlet in order to get the most accurate version of a thermostat.

De’Longhi Slim-Style Portable Panel Heater for $210: This electric panel heater is an interesting hybrid, with dual heat exhausts on each side but also a broad radiant heat panel. This makes for a middle ground between radiators and resistive fan heaters—heating a room much faster than a classic radiator would but still maintaining warm radiant heat over time. This said, it shares a radiator’s main fault, which is that it’s painfully hot to the touch across a large surface—but still issues the same amount of fan noise as a fan heater. Still: It may be your choice if you need to heat up a space quickly and evenly and maintain that heat over time.

Dreo MC706 for $170: New this year, Dreo’s innovative 2-in-1 fan/heater won top marks in our fan guide for its auto-shift positive temperature coefficient (PTC) technology, which moves the heater’s ceramic element aside to allow full fan airflow. Its 1,700 ft/m wind speed is a rarity among tower fans, let alone tower fan/heater combos. It’s not the strongest space heater, but it is sufficient, with five settings, 120-degree oscillation, and tip-over protection. Note that though there is a remote, there are no smart features, and it does not work with Dreo’s app.

Dreo Bathroom Heater for $60: Like Dreo’s smart wall-mounted model I far prefer, this ceramic heater comes with an ALCI plug for safe use near water. I prefer to keep bathroom heaters away from the floor, but not all bathrooms have mountable wall space. This remains a possible, though not ideal alternative, with a somewhat janky thermostat.

Not Recommended

Pelonis 16-Inch Space Heater for $65 and Pelonis 23-Inch Space Heater for $70: Both of these towers heated up quite quickly. Both were also enormously hot at the surface of their vents, with relatively little shielding from the visible heating elements. The 23-inch was significantly quieter than the 16-inch, however.

Vornado VMHi600 for $200: This large cube was about as quiet as the AVH10, staying below 60 decibels, but its vent got quite hot—about 130 degrees Fahrenheit. Other Vornado models perform far better at a far lower price.

Vornado Velocity Cube 5S for $100: This cube’s outer housing stayed quite cool, and the fan functionality is welcome. But its surface vent got a little hot, and the fan was a bit on the noisy side compared to other Vornados.

Vornado Velocity 5R Whole Room Heater for $125 and Vornado VHEAT for $160: Our top pick MVH from Vornado is one of the quietest space heaters I’ve tested. These were two of the loudest. The 5R topped 70 decibels. The vintage-looking VHEAT is quite lovely, but it’s also a bit of a noisemaker.

Lasko MyHeat Mini for $40: This little thing looked cute, and I thought it would be a nice desktop or under-table personal heater. But even with its low output at 400 watts, the vent got way too hot to want it anywhere near your laptop or papers.

Lasko 22-inch Oscillating Tower With Remote for $80: This one failed our tip-over test when we knocked it over, blasting heat endlessly into the rug until it overheated and sent a burnt-plastic smell into the air. It did restart hours later, meaning this shutoff was a safety feature. But this tower’s a bit too tall and tippable to risk repeating these events often.

Honeywell 2-Position Heater for $45: This compact, simple, analog heater was a nice enough idea, able to rest vertically or on its side. Lord, it’s loud when its fan is in operation, though.

Honeywell Compact Ceramic Tower for $47: This Honeywell performed well in terms of fast heat and safe surface temperature. Its fan wasn’t too loud either. But the one we received had a maddening squeak each time the tower oscillated fully counterclockwise.

Gone but Not Forgotten

Vornado Sensa Cribside Heater: I loved the idea behind this Vornado Sensa Cribside Heater when I tested it: A space heater with an external temperature sensor, with therefore accurate temperature management (hard to find among space heaters!) But it’s disappeared from Vornado’s website, and has dwindled on retail sites. It’s no longer available on Amazon, but if you see it on sale at another site, I still like it.

Also tested but discontinued: Morento 26-cm Heater, Morento 40-cm Heater, Dyson HP07, many models of Vornado before the brand’s 2025 refresh.

This Speaker I Tried From Soundboks Can Handle a Real Party

This Speaker I Tried From Soundboks Can Handle a Real Party


In addition to the rubber balls, there’s a nice physical interface on the side for adjusting volume and pairing multiple Mix speakers together if you have multiple on hand (I was only sent the single mono speaker). Setup involves installing the Soundboks app, pairing to the speaker via Bluetooth on your phone, and picking whatever you want to play. It’s all quick and painless, especially for my first-time pairing with a Samsung Galaxy S24 Ultra.

Otherwise, it’s all very pro audio. Everything reminds me very much of the Peavey PA system I have in my music rehearsal space. The top of the speaker features a built-in carrying handle and a place for a strap (an accessory you have to buy aftermarket, or you can fasten it with any strap you have that fits through the hole). There are also top-hat mounts for the speakers to slide onto traditional PA pole stands, if you wanted to use them in that way at a party or event.

The grill is replaceable, as is the massive internal battery, which means that these things are pretty much indestructible as long as the amp and speakers themselves still work—the battery is the weak point of most portable speakers in 2026.

I bounced it around my yard, dropped it off my patio, and generally beat the crap out of it during my two-week testing period, and the thing just needed a little wipe down and a charge when it ran out of juice. The claimed 40 hours of battery at reasonable volume is accurate, but you’ll get about eight hours at max volume (which is very good for the category). If you need to bring some walk-out music to your kid’s all-day Little League tournament, this a great way to go.

Soundboks calls this speaker midsize, but at 21.4 pounds and the size of a medium-size cooler, I’d still call it a large speaker. That said, the size doesn’t make it any less portable than competitors from JBL and others; you still need a car or cargo ebike to take one of these with you, so what’s a couple inches here or there? The fact that this is a rectangle actually makes it easier to strap down than many others, especially with the holes for the strap and the built-in handle to tie down through.

Affordability Doesn’t Suck With Eufy’s Newest Robot Vac

Affordability Doesn’t Suck With Eufy’s Newest Robot Vac


Where the X10 Pro Omni had rotating mop pads, the rolling mop pad on the Omni C28 continuously self-cleans to prevent spreading dirt or grime to other parts of the house. Both apply downward pressure, but neither can spot dirtier places on their own as pricier, AI-powered robot vacuums will. Still, I was happy to see that it was able to scrub away some of the large dirt smudges in my entryway, though it didn’t get all of them. It also didn’t manage to scrub away all of the cherry juice I intentionally spilled in my routine mess setup for robot vacuum testing, even after sending the vacuum to do a second mopping job on one of the spots.

Still, the Omni C28 was able to raise its roller mop high enough when it switched from mopping my floors to vacuuming my living room rug that there was no hint of dampness anywhere. The older X10 did get my colleague Adrienne So’s carpet wet, but it didn’t get mine wet, though my carpet is a fairly low pile. It did a fine job vacuuming the carpet, though I could tell the difference in suction between this and more powerful vacuums I’ve tested.

The base station is nice and compact, and includes drying fans to dry off the roller mop. That does mean there’s a gentle fan noise in the background for a couple of hours after you use this robot vacuum, which was more annoying than I expected, but you could easily place this vacuum’s base station in a less central spot in your home so you don’t hear it. You could also set up a schedule for the vacuum to run in the morning and finish its drying job before you get home.

Multi-Floor Madness

My favorite feature on the Omni C28 is that, even at this price point, it can still learn multiple maps. While it can’t climb up stairs, you can move it around your home and switch the maps in the app to the floor you’ve relocated to. This isn’t new for Eufy, as the older affordable model can do that too, but it’s nice to see the feature maintained when I’ve tried more expensive robot vacuums that don’t include it. It’s pretty simple to use; you’ll go to the maps, select “make a new map,” and then activate the robot to map. Once the map is made, you’ll switch to that map from the little map icon on the right side, which will label them with numbers in the order you created them.

‘She’s Never Going to Age’: Porn Stars Are Embracing AI Clones to Stay Forever Young


Lisa Ann technically quit the porn business in 2019, but for $30 a month you can now dream up any X-rated scenario of her on your computer.

Ann, 53, was an adult performer for three decades starting in the mid 1990s and retired because she had reached her savings goal.

But last year she had a change of heart. Ann, who considers herself an AI fanatic, signed a contract with OhChat, a London-based AI companion company, to license her likeness on its platform, essentially creating an AI version of her in every way that can be used to make sex scenes for paying customers: same voice, same physique, and same pillowy brown hair.

As issues around deepfakes intensify and questions about the future of the adult industry become more dire with the passing of age-verification laws, several AI companion platforms want to create a new standard for consent-driven AI porn. More than sexting a faceless chatbot, digital twins—also called duplicates, doubles, clones, or replicas—draw on the exact likeness, including speech and mannerisms, of your favorite performers and creators.

Ann, now a self-help author and sports radio host, represents a growing faction in adult entertainment who not only believe AI is going to reshape the sex industry but who want a say in how that change materializes. She sees the decision to partner with OhChat as a way to tap into a fountain of youth—and stay at her peak forever.

“This keeps my name alive,” she says of her digital twin. “She’s never going to age.”

For Cherie Deville, a 47-year-old performer known for shooting MILF content, digital twins are just a smart business strategy to earn passive income while the opportunity is hot. “We can either let the makers of AI take the lion’s share of the money in the sex-work space, or creators and businesses can get on board and start creating their own revenue sources through AI.”

OhChat creators, who must submit 30 images and undergo voice training with a bot, sign an agreement stating the level of sexual content allowed for their digital twin. Ann is considered a “Level 4”—the highest on the platform—which means paying members can create scenarios and chats of her that include full nudity and sex. Per the company’s guidelines, clones can be deleted at any time.

“For guys that like to say good morning or good night, they now have that access. The fact that I’m not shooting scenes anymore also allows new scenes to be created,” Ann says.

Once described by CEO Nic Young as the “love child between OnlyFans and OpenAI,” OhChat launched in 2024 and has since scaled to over 400,000 users. According to data shared with WIRED, OhChat has 250 creators, 90 percent of which are female, and has contracts with celebrities Carmen Elektra and Joe Exotic. The platform runs on a tiered subscription model—$5 a month for on-demand texts or up to $30 for unlimited adult content—and the company, like OnlyFans, takes a 20 percent cut.

Other competitors in the space include My.Club, Joi AI and SinfulX AI, the platform that adult film actress Georgia Koneva partnered with this month, saying, in a press statement, that her avatar gave her a “new way to share my voice and personality with the people who follow me.” According to SinfulX AI, it also develops “original” synthetic characters using licensed source imagery from adult performers whose content it has the rights to use. In the same statement, the company said that those AI-generated “characters” are “designed not to replicate any single individual while still maintaining the realism for which its content is known.”
