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 a cool-to-the-touch exterior, an 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,” said 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.

The Lasko Artisan Series offers a smart blend of style and performance. With its sleek black ceramic tower and light wood base, it looks more like a decorative piece than a typical space heater. It’s compact, easy to place in any room, and designed to warm up larger spaces like bedrooms, home offices, and living rooms. Despite its small footprint, it delivers powerful, consistent heat thanks to its 1500-watt output and widespread oscillation.

In lab testing, this model stood out for how quickly and evenly it warmed up a room. It includes key safety features like overheat protection, tip-over protection, and a cool-touch housing, all of which meet the safety standards our experts look for. One tester noted how quickly the unit reached the set temperature and appreciated the built-in thermostat, saying it could help reduce heating costs during colder months by maintaining the right level of warmth without running constantly.

The controls are straightforward, with a large digital display and two comfort heat settings that are easy to adjust. A six-function remote makes it even more convenient, letting you control everything from across the room. Testers also liked that the unit comes fully assembled and is easy to move from one space to another. Such a stylish unit would look great in other colors, but it's only available in black.

With reliable performance, useful features, and a look that complements modern decor, this heater is a strong option for anyone looking to warm up their space without relying on central heat.

The Lasko Ellipse Ceramic Heater is a strong performer in a compact, lightweight frame. Weighing just over three pounds, it’s easy to move from room to room and fits neatly on a table, desk, or shelf. Its curved design feels more intentional than most small heaters, and the wide grill paired with 120-degree oscillation allows it to push heat evenly across a medium-sized room. During testing, our engineers noted that this model “packs impressive heat output in a compact housing,” making it a great pick for bedrooms, home offices, or smaller living spaces.

Testers appreciated how quickly it starts up and how simple it is to control. The top-mounted buttons are intuitive and visible from above, which makes setup and adjustment more user-friendly. One tester shared, “It starts up and gets hot immediately. The oscillation is a great feature.” Another noted, “It’s compact, reasonably attractive, lightweight, and effective. I like that it has three heat settings and two fan settings.” In addition to the customizable heat options, the unit includes a 12-hour timer, AutoEco energy-saving mode, and a seven-function remote control with onboard storage.

Safety and quiet operation are also key benefits. The heater runs under 40 decibels, so it won’t disrupt sleep or work. It includes overheat protection, a tip-over switch, a child lock, and cool-touch housing for added peace of mind. While this model scores high in performance and features, its small size means it’s not intended for heating large rooms.

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 bladeless, and there are no visible heating elements. Plus, the Dyson will automatically shut off when tipped over.

We also like 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.

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 bedroom 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 appreciate that it'll automatically turn on if the ambient temperature dips below 41°F, to prevent pipes or plants from freezing.

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.
