Best Radiant: Dr. Infrared Heater 1500W Original Portable Space Heater

Our top choice for the best radiant space heater will warm you up in a hurry while taking the chill off a room. This popular model combines quartz infrared heating elements with ceramic technology for a dual approach to warming up a room. While the infrared heat warms people and objects, a blower assists in distributing warm air to raise the temperature of the room. According to the manufacturer, this unique design allows the unit to heat 60 percent more efficiently than many other space heaters available.  

Reviewers find that the unit's built-in thermostat does an excellent job of cycling the heating elements on and off to maintain the set temperature. This heater is rated for use in up to 1,000 square feet and many people have found it able to keep their living room, kitchen, and other frequently used areas warm without resorting to turning on the whole-home furnace. 

However, keep in mind that since this radiant heater also incorporates ceramic heating technology, it may cause the humidity levels in your home to drop more than a typical infrared heater. Some reviewers were disappointed to find that the air was drier than expected, so if maintaining humidity during a dry winter is your top priority, than you may be better off with a conventional radiant heater.

Best Radiant, Runner Up: Lasko 1500W Cool-Touch Infrared Portable Heater

Radiant space heaters offer focused heating, rather than warming the air in a room. If you want to feel the warmth right away or want to snuggle up on a warm sofa, then an infrared heater like this model is your best bet.

This 1,500-watt radiant heater uses quartz elements to generate infrared heat, which warms up objects and people, rather than their surrounding air. It can be used to warm your bedroom or living room, even if there isn't much air circulation to move the warm air around. It’s also incredibly useful in areas where it’d be nearly impossible to raise the overall temperature of your surroundings, like in a garage or on a patio. 

Users also love the fact that this space heater stays cool to the touch and isn’t a safety hazard if children or pets happen to bump into it. It offers several different heating modes, including a ‘save-smart’ mode that will keep the unit within three degrees of the target temperature. While a few reviewers find this Lasko radiant space heater to be a little noisy, most are very satisfied with its warming abilities and efficient operation.

Best Convection: DeLonghi 1500W Ceramic Tower Electric Space Heater

If you’re looking for a convection space heater to warm up a room, then this 1500-watt model from DeLonghi is the best option. The tower design allows the heater to oscillate, spreading the warmth more evenly and effectively throughout the room. It offers three heat settings to dial in your perfect comfort level and is recommended as a supplemental heater in rooms up to 300 square feet.

Like most convection space heaters, the DeLonghi 1500-Watt Ceramic Tower model includes a tip-over switch for safety, along with an eco-mode for energy conversation. What sets this convection space heater apart is its oscillation feature, along with the convenience of remote control operation. It even has a fan-only setting, so you can keep it out year-round to help you feel cooler in the summer months, as well.

Best for Large Rooms: Lasko Bladeless Ceramic Heater with Remote Control

While radiant space heaters are great for heating people and objects in relatively close quarters, a convection space heater warms the air in a room, which is a better option for large rooms. 

Measuring just over 2 feet tall, this convection space heater doesn’t have a grill covering a heating element. Instead, the center of the ceramic heater is open space, with an internal fan that blows the hot air from inside the unit out into the room. This open-air channel is designed to blow the warm air further than other conventional space heaters. 

Users have had good success using this convection heater in bedrooms, living rooms, and basements. It is rated to heat rooms up to 300 square feet in size. The bladeless design is also quieter than some other convection space heaters, and this model includes two “quiet heat” settings for warmth you’ll feel—but won't hear!

Best for Office: NewAir Portable 400W Space Heater with Energy Efficient Operation

Stay warmer at work with a personal space heater for the office. The slim dimensions and low wattage of the New Air Portable Space Heater make it a top option for tight spaces. With a simple on-off switch and a variable temperature dial, you can crank this heater up as high as you need to or choose gentle warmth to take the chill off while you're at your desk. 

This portable space heater is only recommended to heat about 40 square feet—perfect for your office or under the desk. Inside the slim profile of this space heater (it only measures 2 inches wide!) is diathermic oil that conducts heat especially well. The result is a toasty warm glow to keep your feet warm, even after the heater has been turned off.

Best Energy-Efficient: Heat Storm Wi-Fi Infrared Heater

Incorporate an energy-efficient space heater into your home for comfort that conserves energy. The Heat Storm Wi-Fi Infrared Heater can be wall-mounted or simply rest on the floor. It puts off 1,500 watts of power or 750 watts in eco-mode, using quartz infrared bulbs. It’s a great option for drafty rooms since it will warm people and objects in its path, regardless of whether or not that nearby window is leaking cold air!

Perhaps the best thing about this energy-efficient heater is the fact that it’s compatible with Amazon Alexa and Google Home. It’s a great match for smart homes and can be scheduled via an app or even remotely turned off. This comes in handy if you leave home and want to make sure you’re not risking a safety hazard or wasting energy by operating a space heater while you’re gone. 

Best Budget, Radiant: Comfort Zone 1500W Infrared Radiant Tower Heater

Reap the benefits of a radiant space heater without spending a fortune, thanks to the affordable Comfort Zone Infrared Tower Heater. Inside the tower-style space heater are two quartz heating tubes that produce infrared heat to warm people or objects in front of the unit. There’s no digital display on this budget radiant heater, but you can opt for a low or high setting and then use the adjustable dial to select a temperature that is just right for you.

It’s a great choice if you need a compact heater to keep one or two people warm in a room or if you have drafts or tall ceilings and don’t want to crank the heat up in your whole home.

Best Budget, Convection: Lasko 1500W Electric Ceramic Heater

This model is frills-free but offers basic heating functions without breaking the bank. Users are consistently pleased with the steady heat output of this space heater, especially at its relatively low price point.

This Lasko heater offers 1,500 watts of power and adjustable settings to get the temperature just right. You can choose from three fan settings including high, low, and a fan-only option for circulation without heat. An adjustable dial lets you select from 11 different temperature settings. It's hard to beat this model if you're looking for a cheap, functional space heater without added frills.
