Best Space Heaters of 2025, Tested & Reviewed

Small but mighty, we found that this top-rated space heater can circulate warm air throughout a room in minutes. It features three heat settings (750 watt, 1125 watt and 1500 watt) so you can control just how much heat output you need.

We also love that it's packed with a number of safety features. The case stays cool to the touch and a wide base helps prevent it from being knocked over. If it does get tipped over (or if it starts to overheat), it will automatically shut off.

A built-in carrying handle makes it easy to take the heater with you throughout your home, and our pros love that it's whisper quiet. One customer said it's "the quietest forced-air heater I've come across." Other online reviewers loved how effectively the Vornado space heater warms up large rooms, which is impressive given its compact design and the fact that it's only advertised for medium-sized rooms.

Though some users complained of reliability issues after using the unit for years, in our testing we found Vornado's customer service to be extremely responsive and your purchase comes with a five-year warranty should anything go wrong.

This compact space heater from Dreo is a great way to stretch your wallet while keeping smaller areas of the home toasty warm — or you could pick up two units for larger spaces and still end up saving a bundle.

Despite being one of the smallest and most inexpensive options we evaluated, the Atom 316 has one of the widest feature sets — including an adjustable thermostat — and packs as much heating power as models that cost over three times as much.

During extensive Lab tests, the heater raised the temperature of a medium-sized room by 7°F in just 30 minutes on maximum power. At its maximum setting, the sound level was 47.9 decibels from 6 inches away — about as quiet as a typical home refrigerator. It’s also loaded with safety features, including cool-to-the-touch exterior, automatic timer and tip-over protection. To prevent overheating, the fan even runs for 30 seconds after the heater shuts off.

The only potential negative pointed out by testers is that the heater’s touch-sensitive buttons may be difficult for some users to locate or identify since they're not backlit and lack tactile feedback.

When our team set about developing a Good Housekeeping-branded space heater, safety was every bit as important as heat output. The result: this 30-inch oscillating ceramic space heater with all the safety stops, like overheat protection with automatic shut-off, cool-touch housing and a tip-over safety switch. “You still need to follow every safety precaution, including keeping any flammable objects at least three feet from the heater,” says DiClerico. “But when used properly, the heater will keep you safe and cozy in spaces up to 200 square feet.”

The Good Housekeeping tower space heater was also designed with convenience and usability in mind. The remote control lets you operate it from the sofa or bed, while the 12-hour timer is good for programming the machine to turn off after a set period. And while the 30-inch-tall heater throws plenty of warm air, its footprint is just 8 square inches, so it won’t take up too much floor space.

For less than $40, Lasko's little space heater — it's under 10 inches tall! — will keep a full room warm without costing a fortune. It comes with low-heat, high-heat and fan settings, and we found it to be lightweight enough, at just over 3 pounds, to carry from the bedroom to the bathroom to the kitchen and back with no hassle. Plus, there's a built-in handle to make it even easier.

Many users set this space heater up on a countertop so they don't need to bend down when they're ready to move it to another room or adjust temperature settings. Other online reviewers reported keeping a Lasko space heater at their work desk. One thing to note: This electric heater doesn't come with an auto-shut-off safety feature like some of our other top recommendations, so you'll want to keep an eye on the machine when it's on.

Though it may be the priciest unit on this list, this premium three-in-one appliance from Dyson is a space heater, a fan and an air purifier so you can use it year-round. Not only is it able to warm up cold rooms, but it can provide some much-needed breeze in the summer. Even better, it helps purify the air no matter what mode it's in. The sealed HEPA filter channels hot or cold air into the room, all while removing common allergens including dust, smoke, pollen and dander.

The heat function is controlled by a thermostat so you can choose the exact temperature you want. In the automatic setting, the fan will kick into high gear until your desired temperature is reached and then will quiet back down to maintain your ideal environment. It's also safe: The fan is blade-less, and there are no visible heating elements. Plus, the Dyson will automatically shut off when tipped over.

We also appreciate that while a remote is provided, you can use the MyDyson app to control your air quality or voice assistants such as Alexa, Siri and Google for quick, hands-free adjustments. A digital display shows you the air quality at a glance, among other settings like fan speed. Just keep in mind that at over 10 pounds, it's not the easiest space heater to move around.

This sleek and slim tower has a small footprint that easily fits into most rooms. We love the timer feature that lets you set it to run all night (or day) for up to eight hours before it shuts off automatically. Though we wish it offered more than two heat settings (high or low), we like that the exact temperature in the room is displayed on the space heater. The heat setting can be turned up or down with the included remote control.

"The heater's height and the rotation help evenly spread heat throughout the room," one online reviewer said. "It runs smoothly and quietly and the base is stable even on thick carpet." For safety, the unit stays cool to the touch and will shut itself off before it overheats, but it doesn't include tip-over protection which could become a fire hazard should the heater tip over unknowingly.

In comparison to our best overall Vornado space heater, the AVH10 features a digital display so you can see the numerical temperature reading directly on the unit. It has three settings (low, high and fan only), and the manufacturer claims it has a multitude of safety features like a cool-touch exterior, tip-over protection and automatic shut-off.

In tests, our pros were impressed by its ability to heat up medium- to large-sized rooms. Other testers noted that despite its small size, it's quite powerful and operates quietly. It's "very effective at distributing the heat throughout the room and much quieter" than other Vornado models, one online reviewer said. "The automatic temperature controller works very well and the controls could not be simpler." Although some Amazon reviewers noted the product has a short lifespan.

For a more discreet electric space heater that can blend right into a wall, look no further than this model from DeLonghi. At just 3 inches deep but 32 inches wide, it can replace a radiator to warm up a space as large as 300 square feet, like a bedrooms or basement. Just note that the air blows out the sides, so you'll need to have a little extra space around the heater for proper airflow.

You can set the space heater on the floor or use the included mounting kit to hang it up to save floor space. One online reviewer said it's the only heat source she uses to get through the winter in her South Carolina home, while others loved its attractive design, compact size and efficiency. Though it's larger and heavier than other models we've tried and doesn't come with a remote, it's a great semi-permanent solution and one that's impressively quiet. It also has a 24-hour timer so you can program it to shut off when no longer needed.

It includes safety features like tip-over protection and auto-shut-off should it overheat. We also appreciate that it'll automatically turn on if the ambient temperature dips below 41°F, to prevent pipes or plants from freezing.

This little cutie will never be an eyesore on your desktop, nightstand or floor, and it's affordable enough to give to a college kid or a work colleague who complains about being chilly. While the manufacturer says it's best for personal use in small spaces, like an office or a dorm room, online reviewers were pleasantly surprised to find that it can keep an entire bedroom cozy.

Its compact size makes it easy to move around so you can stay warm wherever you go, though we did find that it’s noisier than other space heaters. But those who like white noise and sound machines may actually enjoy that attribute. It also comes with key safety features like tip-over protection, a cool-to-touch surface and overheat protection.

We love this space heater for its vintage appeal with modern engineering that quickly and safely heats a room. This one inspired by a classic 1945 design is available in green or white and has tip-over protection should you knock it over as well as an automatic shut-off feature should it get too warm.

Though we wish it offered more heat settings, we found that this space heater is the perfect size to place by your bed or desk. The fan tips up and down so you can adjust the heat to flow right where you want it. But because it's all metal and a bit heavy for its size, it's best to choose a place of honor for it and leave it there.
