10 Best Space Heaters of 2024, 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 (750W, 1125W and 1500W) 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 carry handle makes it easy to take the heater with you throughout your home, and it should be whisper quiet. One customer says it's "the quietest forced-air heater I've come across." Other online reviewers love 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 is an affordable purchase for individuals and families looking to heat up their garage, bedroom or living room without sacrificing space. The manufacturer claims the product can cover up to 260 square feet, and it has three heating modes for easy adjustability: fan only, low heat (750-watt) and high heat (1500-watt). With a 4.5 rating on Amazon and more than 33,000 five-star reviews, it's a solid choice that won't break the bank.

One of our tech experts used this space heater to keep a large room warm and appreciated how quickly it was able to heat up. She confirmed the tip-over shut-off feature works effectively, so you won't have to worry about accidentally knocking it over. Other safety features include an automatic overheat shut-off and a power indicator light to confirm when the heater is plugged in.

At just under $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 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 report 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.

This popular DeLonghi space-heating tower comes with a large digital display that lets you easily see the room's temperature, plus controls that make it a breeze to adjust. On top of being quiet, it also includes a tip-over feature, automatic shutoff if the room gets too warm, a programmable timer and a remote that lets you crank the heat up or down without getting up from the couch.

According to the brand, this heater suits spaces up to 150 square feet in size, so it should be a good fit for bedrooms, smaller living rooms and offices. We particularly liked how this tower heated small spaces efficiently with effective, adjustable oscillation that you can turn on and off with a foot pedal. Unlike other heaters on this list, this one has an ECO function that optimizes heat and power settings to be energy-conscious and help save money on your energy bill.

Though it may be the priciest unit on this list, this premium appliance from Dyson is a space heater and a fan 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 super 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. 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 to easily fit 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 height and the rotation help evenly spread heat throughout the room," one online reviewer says. "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.

We have been testing this product for months to see how well it works, and thus far we've been 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 says. "The automatic temperature controller works very well and the controls could not be simpler."

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 bedrooms or basements. 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. It includes safety features like tip-over protection and auto-shutoff 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.

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 rave about its attractive design, compact size and efficiency. Though it's larger and heavier than other models we've tried, 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.

This little cutie will never be an eyesore on your desktop, nightstand or floor, and it's affordable enough to send to a college kid who complains about being chilly or a colleague who's always shivering. While the manufacturer says it's best for personal use in small spaces, like your 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 fans of 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 1945 vintage appeal with modern engineering that quickly and safely heats a room. Like other Vornado space heaters, this classic design 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.
