Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed products and single out the most convincing ones. (You can learn more about our rating system and how we pick each item here.)

And while we’ve written about lots of practical home goods — including dish racks, clothes steamers, and microwave ovens — here, we’ve rounded up the best space heaters, as praised by the most enthusiastic reviewers on Amazon.

Best-rated space heater

Lasko Ceramic Space Heater
$52

Many folks who love this heater already own one of Lasko’s well-reviewed tower fans. “It moves (rotates) like those moving fans,” says one happy customer, adding, “It has a built-in thermostat, so it keeps the room to a steady temperature. It works. (We used it in the bedroom when it was 15 degrees outside and it kept the bedroom to a nice 75 degrees.)” One comprehensive reviewer says of this oscillating ceramic space heater, “Even though most electric ceramic heaters are mostly rated at the same (1500W), this one differentiates itself by being able to move air in a wider cone due to the oscillation feature, which I almost always leave on. I use this in my master bathroom and it’s stopped me from shivering after showers due to the ability to create a difference of 10 degrees Fahrenheit between my bathroom and adjoining bedroom under 15 minutes (68 to 78 Fahrenheit).”

Best-rated (less expensive) space heater

OPOLAR Mini Ceramic Heater with Infrared Human Sensor Feature
$17

“Looks can be deceiving because this heater is the size of a portable desk speaker,” one reviewer writes, and even though it “looks more like a ‘hand warmer,’” lots of reviewers think that it is more than powerful enough to heat their small spaces. “At my desk it keeps me warm and helps to loosen up my achy fingers,” one writes, while another says, “This heater really surprised me by heating my bathroom up just enough for me when I get off from shower.” It comes with a safety tip-over feature as well as a body sensor, so there’s less of a chance of forgetting to turn it off. “The person sensor does a good job of keeping it running only when motion is sensed,” one reviewer explains, while another notes, “The person sensor reminds me to get up and move. So, it’s good for your health.”

Best oscillating space heater

Lasko Oscillating Ceramic Tower Heater, 16-Inch
$39

Don’t be fooled by the size: This is “much more powerful/useful than you’d imagine a space heater to be,” writes one reviewer who was particularly impressed by how well this heater warmed up their one-bedroom apartment with vaulted ceilings. “Within minutes of plugging this baby in, the room was nice and toasty,.” More than 10 percent of reviewers believe that his heater’s oscillating feature is what helps it heat up spaces so quickly. In one users 2,000-square-foot home, “It got down to 46 degrees last night and with this running in the living room, oscillating, the bedrooms were at 71 and the rest of the house was at 75.” Another reviewer says it’s powerful enough to heat their 17-by-15-foot living-slash-dining room: “Visitors to my apartment, when they step in, tend to remark that it feels like the Caribbean in there.” And while plenty of users use it for direct heat, one user who calls the oscillation mode “underrated” thinks the heater “works more efficiently when I oscillate the heater in comparison to when I choose not to.”

Lasko Designer Series Ceramic Space Heater
$46

Reviewers sang the praises of this stylized space heater, with one writing that it “looks much nicer than a typical space heater.” Another says, “The style is so lovely, our company hardly notices it’s a heater.” However, good looks don’t mean this space heater is wimpy: “Do not be fooled by the small size of this heater. It takes the chill out of the air within ten minutes and warms comfortably our 27-foot travel trailer within 20-30 minutes.” One reviewer was so impressed by this heater, they bought it again and again: “After my first order, I ordered two more of these Lasko ceramic heaters.” Another reviewer says, “The gentle operating hum is tolerable and the oscillating movement glides. I have had many heaters but this one is the best. Lasko delivers again!”

Best space heater for large spaces

AmazonBasics Portable Eco-Smart Space Heater - Wood
$90

This space heater claims to heat rooms up to 1,000-square-feet, but there’s lots of five-star reviewers who say this has no problem heating spaces even larger than that. “My house is approximately 2,000 feet but if you put this thing on full blast, it keeps the main floor and the basement warm enough,” one writes, while another uses this to heat their basement and garage. “This space is ~1,400 square-feet. We have been very impressed with how much of this large space is heated by this little guy.” One customer says this heater is so powerful, it “warms my living room up sometimes too much.” But there are also lots of different settings to be able to dial it in to the most comfortable temperature. “The heating element is located in the base of the unit, a fan blows across the element and pushes heat out of the port vent on the face of the unit,” one reviewer explains, and this, in turn, “keeps the outside of the unit safe to touch, and there is no exposed elements for little fingers or pets to accidentally touch.”

Best compact space heater

OPOLAR 1500W Ceramic Space Heater with Adjustable Thermostat
$40

“Do not be deceived but the compact design of this heater,” writes one reviewer who uses it to heat a game room for their teenage grandkids, noting, “If they close the door it can become a sauna in there!” A majority of five-star reviewers reiterated that for its size this heater is a powerhouse. “It actually heats the entire upstairs. This past week it was -50 with windchill and our furnace was having trouble keeping up. We brought this heater down to the living room in the morning and by noon it was up to 72,” one customer writes. And another reviewer who likes to use it on camping trips says, “On the low setting it warmed the tent up in just a few minutes. It is very quiet and we love the compact size. Now we are looking forward to camping in the cooler months knowing we can sleep in comfort.”

Best personal space heater

Lasko Model 100 MyHeat Personal Space Heater
$15

With over 3,500 five-star reviews, this personal space heater from Lasko is lauded by many as a great little heater. That does mean it’s got some limitations, as one reviewer points out: “This is meant to be by your side or aimed at your hands/feet. This is not going to sit five feet away and keep you warm unless you keep the door closed for an hour or more.” But still, they continue, “This has been the perfect solution to keep my extremities warm without having to heat my entire office up. I even use this in the summer when the rest of the office has the AC set at a low temperature.”

Another reviewer writes that it “gets the job done” at keeping their hands warm in an over-air-conditioned office but won’t heat a full cubicle. A third uses it to cope with their family, explaining, “My brother is a cheap jerk who keeps the heat, if you can call it that, at 66 degrees when it is 15 degrees outside in the dead of winter. I smuggle this heater into his house and use it in the bedroom whenever I stay over, which is not often. It is very small and quiet. It heats the room just enough so that I am not freezing my balls off at night.”
