To give you an idea of the space heater choices out there, I rounded up expert-recommended options at various price points.
This space heater comes recommended by NBC Select SEO editor Nikki Brown, who loves how quickly it warms up. “This heater is small but it packs a punch. On the highest level, it heats up a large room in under an hour,” she says. “There’s also a mechanism on the bottom that can gauge if it’s sitting on a flat surface or not. If it’s not, it will automatically turn off, which I love.” The heater is made of flame-resistant material and can heat a room up to 200 square feet, according to the brand.

Wiseman recommends this portable infrared model for its dual heating system and built-in thermostat that ranges from 50 to 85 degrees Fahrenheit. The energy-saving space heater offers 1,500 watts and is powered through an electric cord with 120 volts, which can evenly heat a 150-square-foot room, he said. It also has an automatic 12-hour shutoff timer.

The nice thing about this lightweight, compact space heater is that it can either be mounted on the wall or set on the floor. It also comes with wheels so you can easily move it from room to room. It packs a powerful punch with 1,500 watts of heat and has an adjustable thermostat and multiple heat settings so you can personalize for your comfort, according to the brand.
Type: convection | Safety features: auto shut-off | Testing: n/a | Warranty: 1 to 2 years
Van Tuijl recommends this wall-mounted, convection space heater, which has a temperature-controlling thermostat and the brand’s Wall-Sens technology, which cuts out the power for safety when the unit is removed from the wall, according to the brand. The unit, which Envi says heats rooms between 130 and 150 square feet, is just 2 inches thick and can automatically dim the power light in dark rooms.
Type: convection | Safety features: temperature-controlling thermostat | Testing: UL | Warranty: 3 years
This Lasko space heater has a bladeless design at a more affordable price than similar brands, like Dyson. Lasko says it’s equipped with a slew of safety features, including a safe touch surface and an automatic 8-hour shut-off switch. With its quiet oscillating mode, this tower can evenly distribute heat in rooms up to 300 square feet, according to the brand.

Van Tuijl recommends this convection space heater from Dreo due to its easy-to-use touch screen panel, strong heat output and remote control capabilities. This model has three heating modes and a digital thermostat that ranges from 41 degrees to 95 degrees Fahrenheit. It also has a timer that automatically shuts off after 12 hours, and the remote lets you turn the unit off from up to 26 feet away, according to the brand.

The bladeless Dyson Pure Hot + Cold is a remote-controlled combination heater, fan and air purifier all in one, according to the brand. The remote-controlled fan can oscillate up to 350 degrees and offers different modes, including a backward airflow mode that diverts air through the rear of the space heater, continuing its purifying effect without the draft, according to the brand. It also includes a nighttime mode with a dimmed display, according to Dyson. Wiseman noted this space heater is “substantially quieter” than many other models and can regulate indoor air quality: using a HEPA-style filter, it can capture 99.97 percent of particles that are 0.3 microns in size, says the brand. The unit can also connect to Wi-Fi so you can control your machine remotely and schedule when your air purifier is on, using the Dyson Link app.
Type: combination electric | Safety features: n/a | Testing: UL | Warranty: 2 years
The most affordable option on this list, the portable Lasko Oscillating Ceramic Heater, is a worthwhile option if you’re on a budget. Lasko says this space heater can heat rooms up to 300 square feet and offers two heat levels — low heat and high heat — along with a cool air fan setting. You can also use the thermostat knob to both turn on the unit and have it shut off automatically once a certain temperature has been reached (though the knob itself doesn’t list actual numbers), according to the brand.

Once you’ve decided that you want a space heater, factor in the aspects below to choose the exact one that’s best for your space and situation.
Decide on a type
Choose between a radiant, convection or combination space heater. Depending on your living situation, one may be better for you than the other. If you have a small space, choose a radiant heater and if you have a large space to warm up, a convection may be best. Additionally, if you don’t mind the noise, a combination space heater is good for families with small children since they’re less of a safety hazard, according to our experts.
Consider where you’ll put it
In addition to the type of space heater you want, you should consider where you’ll put it, which will determine what size and shape is best. Plus, if you’re only getting one to heat a small room, this will further make it easier to decide on a type.
Noise level
Some space heaters tend to make a lot of noise, some more than others. Keeping this in mind, I made sure to include units from brands that mention minimal to moderate noise. units are louder than others. If you’re shopping for a bedroom or home office, that’s something to keep in mind. One resource for finding devices that are especially quiet is Quiet Mark, which tests and awards products based on their noise output.
Take energy efficiency into account
Space heaters are generally more energy efficient than central heating since you’re only heating up the room and some space heaters are also more energy efficient than others. Since space heaters don’t have Energy Star ratings — which independently certifies a product’s energy efficiency — the easiest way to determine if your unit conserves energy is by checking whether it has features like an adjustable thermostat and auto shut-off option that can maintain a certain temperature and prevent a room from overheating, according to the Department of Energy.
The U.S. Consumer Product Safety Commission estimates more than 25,000 residential fires are associated with the use of space heaters every year, and an estimated 6,000 people go to the emergency room for burn injuries associated with contacting the hot surfaces of heaters.
To prevent fires and injuries, many experts recommend looking for space heaters that are tested by independent safety laboratories, like Intertek (ETL) and Underwriters Laboratories (UL). Joel Hawk, principal engineering manager for small appliances at UL, tells us that these laboratories test space heaters based on nationally recognized safety standards, and add that space heaters can be very safe as long as they’re used per the instructions.
While the features that can certify products as “reasonably safe” vary from one space heater to the other, Hawk says his engineers typically look at whether the product adequately responds to overheating conditions or a malfunction (and if it permanently shuts down in unsafe conditions) and whether there are features that prevent electric shock, like suitable insulation and heat-resistant cords. Another important attribute that’s tested is what Hawk calls “personal injury” — UL tests to ensure the unit won’t catch fire and that there aren’t surfaces hot enough to cause a thermal burn or moving parts that may cause injury if they’re touched.
While independent testing and built-in safety features from the manufacturer can mean a space heater is functionally safe, our experts note that common sense also plays a big role in safety. The CPSC recommends the following safety tips to minimize the risk of fire:
To prevent electrical shocks, always keep electric heaters away from water, and never touch an electric heater if you’re wet.
