Best Overall: Duraflame 3D Infrared Electric Fireplace Stove with Remote Control

With a lifelike 3D display, the Duraflame Infrared Quartz Electric Stove combines this timeless sensation of nestling beside the fireplace with modern technology. The item has easy-to-use digital temperature control and, at 5,200 BTU, it can heat a space of roughly 500 square feet.

And with five color options, ranging from classic black to bronze, cream, cinnamon, and French grey, you can find the perfect shade to fit your living room, den, or bedroom. The vast majority of customers give the product five stars, with added praise for durability, strength, and easiness to assemble. Some remark the heater emits a fairly loud hum, similar to white noise, while in use.

"While the Duraflame unit shouldn’t be used as a primary heating method in a home, it did a remarkable job warming up smaller cold rooms in our Rocky Mountain home and added a nice ambiance for visitors in our guest room." — Justin Park, Product Tester

Best for Large Spaces: LifeSmart Infrared Fireplace

To make a large room feel as cozy and warm as possible, you need an indoor heater that’s ultra-efficient and well-equipped to handle the task. The LifeSmart LS 6 Element Large Room Infrared Quartz Heater is the perfect pick, thanks to its ability to heat up to 1400 cubic feet with 5100 BTU’s. It measures 13 x 16.25 x 17.5 inches and can be moved from room to room thanks to the easy-glide casters.

This LifeSmart heater boasts six superior quartz infrared elements, which is why it’s able to produce such an abundance of (quiet and efficient) heat. Built with convenience in mind, it comes with a remote control so you can easily switch to one of three different heat settings. The digital display and raised buttons are also a cinch to use.

If you're worried about how this large heater will look in your home, the LifeSmart Infrared Heater has an attractive wood display. The stylish wood cabinet works well in a variety of decors, but especially in traditional-looking homes.

"The LifeSmart has several welcome safety features that helped us feel comfortable running the unit for longer periods of time." — Justin Park, Product Tester

Best for Small Spaces: Vornado VH200 Personal Space Heater w/ Vortex Circulation Technology

Despite its diminutive stature, the Vornado VH200 Whole-Room Heater packs a punch. It provides warmth up to 300 square feet, suitable for anything from a bedroom to an office to a garage. Three heat settings grant users control over room temperature, and the item’s over-heat protection ensures that it’s safe even when you leave the room. Customers rave about how quiet the heater is, saying it subtly blends into the background noise. Vornado also offers a 5-year warranty, which many customers say is about the length of time that the item will work.

Best Splurge: Dyson Pure Hot + Cool

Thanks to innovative technology and distinctive design, Dyson has established itself as one of the premier household appliance manufacturers. And the HP01 Hot+Cool Purifying Heater and Fan exemplifies why the company is so trusted and so beloved. This bladeless heater-and-fan combo, which measures 24.9 x 8.7 x 8.7 inches, can warm rooms up to 400 square feet or be converted to a pleasant cooling fan during the summer months. One feature that really sets the HP01 apart is that it purifies the air quality as it runs, removing 99.97 percent of allergens, like pollen, mold, and dust. Its many other features can be operated without having to leave your bed or sofa, as the item comes with a handy remote control. Top-quality comes at top dollar, however, as this is one of the more expensive space heaters you’ll see on the market.

Best Budget: Lasko 754200 Ceramic Portable Space Heater

According to the Department of Energy, space heaters can, at times, be more cost-effective than central heating, primarily when used to heat a single room or a small space. That’s why this ceramic heater from Lasko is an unbeatable budget pick. It saves money at the register, thanks to an affordable price tag, and it’s ideal for smaller spaces, providing 300 square feet of warmth. Many customers attest that their electric bill decreased after purchasing. But the Lasko 754200 is not just energy-efficient; the heater is also recommended because of its top performance. The item comes fully assembled and is equipped with a number of convenient features, like a dial with three noise settings and an adjustable thermostat with 11 heat settings. Keep in mind that it does not come with a timer or auto shut-off feature, however.

Best Energy Efficient: Dr Infrared Heater Portable Space Heater

Infrared space heaters typically consume less energy than the more-common convection type, consequently making them more cost-effective too. This comes from the fact that infrared heaters don’t actually pump heat into the air; instead, they carefully transfer heat into cooler objects, whether it be a wall, sofa, or even a person’s body. If you want to read more about infrared heaters, check out our guide.

Along with keeping your footprint green—and keeping more green in your wallet—the Dr. Infrared Original Heater is powerful enough to warm spaces of up to 1,000 square feet. Customers add that it’s extremely quiet, easy to clean, and fitted with several handy features, including a 12-hour timer, remote control capabilities, and easy-to-use temperature adjustment.

Best Ceramic: De'Longhi TCH8093ER Digital Flat Panel

A space heater to stave off the cold, a soothing fan for the summer months—this heater-and-fan combo from De’Longhi is the best of both worlds. While the product drifts toward the pricier end, it has all the amenities you could ask for: remote control capabilities, a 24-hour timer, and an ECO mode that reduces energy output by 20 to 40 percent. Three power modes and an adjustable thermostat give you complete temperature control, and the item’s motorized oscillation ensures that heat or air reaches every corner of the room. The sleek design, measuring 27 x 10.75 x 10.5 inches, along with the digital touch controls make this a stylish addition to any bedroom, living room, or office—perfect for year-round use.

Best Design: Mill CUS1500MECWA PTC Ceramic Fan Heater

With their signature black-and-white aesthetic and slim design, Mill prides itself on producing space heaters that combine function and style. The Norwegian-born company manufactures a wide array of heaters, including ones that are wall mountable or controlled through Wi-Fi, so make sure to check out their other products depending on your heater needs. The PTC Fan Heater is a great place to start, as it is one of Mill’s smallest and most affordable items. At 9.8 x 5.3 x 9.8 inches, it isn’t the strongest heater on the market—recommended use varies from rooms of 100 to 300 square feet—but its minimalist design looks great in any bedroom or office, and larger models are easy to find.

Best Baseboard: Cadet 240-Volt Electric Baseboard Heater

Many customers, especially homeowners, prefer baseboard heaters because of their combination of subtlety and strength. If you want more information about baseboard heaters, take a look at our guide.

Cadet’s electric baseboard heaters check all the boxes: durable, affordable, and powerful enough to keep any room in your house toasty. You can find the item in a number of sizes ranging from 24 to 96 inches long and choose between 208 and 240 volts. Aside from its high-quality performance, the heaters are easy to install and whisper quiet. One important note, however: a separate thermostat will need to be purchased to operate the heaters.

Final Verdict

The Duraflame Infrared Quartz Fireplace Stove is our top choice for space heaters because it’s compact, attractive, and provides an impressive amount of heat. If you’re on the fence about spending that much money, though, go with the Lasko 754200 Ceramic Heater (view at Walmart). It comes equipped with a number of convenient features, like an adjustable thermostat with 11 heat settings.

What to Look for in a Space Heater

Type There are many types of space heaters, but the most common, least expensive, and safest models are compact space heaters with fans. Other relatively safe compact space heaters have ceramic plates or coils. Models with ceramic plates are self-regulating to avoid overheating. Models with coils are often exposed and get very hot, posing a safety risk, especially to those with children and pets. Some floor standing space heaters run off infrared heat or oil. Infrared heats up very quickly but does not stay hot. Oil models are very effective, but large, heavy, and more expensive.

Watts Nearly all 120-volt space heaters are rated up to 1,500 watts at the maximum setting, which is suitable for approximately 150 square feet. Avoid models with less wattage — the price is often comparable and they are much less effective. To heat a larger room, you’ll need to purchase multiple space heaters or consider a larger, more professional-grade heater.

Safety Look for models with automatic shut-offs or temperature regulators, particularly if your space heater will be running frequently or overnight. Always buy models that meet U.S. safety standards. Look for labels that indicate the unit has been tested by recognized labs like UL, ETL, or CSA. And never use an extension cord with an electric heater — choose a model with a longer power cord if proximity to an outlet is an issue.
