It won our main search and our bedroom search: a compact ceramic heater with five modes, an adjustable thermostat, a 12-hour timer and a remote. - **Large rooms:** Dreo 16-Inch Tower Space Heater for Large Rooms. It won our large-room search: a 16-inch, 1,500-watt tower heater with an adjustable thermostat, built for heating large rooms. - **Spreading heat across an open space:** Lasko 751320 Ceramic Tower Space Heater. A runner-up in our large-room search: a 23-inch ceramic tower with wide oscillation and a remote, for open spaces. - **Simple dial controls at a desk:** Amazon Basics Ceramic Space Heater. A runner-up in our main search: a small ceramic heater with simple knobs, a thermostat, and tip-over and overheat protection. Our top pick for most rooms is the **[Dreo 10-Inch Ceramic Space Heater with Thermostat](https://twelvetabs.com/reviews/best-space-heaters/#pick-1)**. It won the main TwelveTabs search we ran for this guide, "best space heater", out of 56 Amazon listings, and it also won our bedroom search. It is a compact ceramic heater with five modes, a thermostat, a 12-hour timer and a remote, and it suits a bedroom, an office or any small room. For a large room, the **[Dreo 16-Inch Tower Space Heater](https://twelvetabs.com/reviews/best-space-heaters/#pick-2)** won our large-room search. To spread heat across an open space, there is the **[Lasko 751320 Ceramic Tower](https://twelvetabs.com/reviews/best-space-heaters/#pick-3)**. And for plain knobs at a desk, the **[Amazon Basics Ceramic Space Heater](https://twelvetabs.com/reviews/best-space-heaters/#pick-4)** keeps it simple. ## How to choose a space heater The Spruce has run more than 60 space heaters in its editors' homes. Its advice, and the safety rules it passes on from the U.S. Fire Administration and FEMA, shape what to look for. Looking at oil-filled radiators instead of ceramic heaters? See our [oil-filled radiator guide](https://twelvetabs.com/reviews/best-oil-heater-radiators/). - **Size it to the room.** The Spruce says compact heaters with fans are best at warming one spot, not a whole large space. That is why we ran a separate search for large rooms, and why a tower won it. - **Heating element.** Ceramic plates regulate themselves to avoid overheating, while exposed coils get very hot, The Spruce notes. All four of our picks are ceramic. - **Power.** Space heaters should not go over 1,500 watts, which The Spruce says is the most you can safely plug into a standard household circuit. - **Safety switches.** Look for overheat protection and a tip-over switch that turns the heater off if it falls. The Spruce calls automatic shutoff one of the most important features it checks. - **A safety listing.** Buy a heater that meets U.S. safety standards: look for a UL, ETL or CSA mark on it. ## Our picks in detail ### 1. Dreo 10-Inch Ceramic Space Heater with Thermostat: best for bedrooms and small rooms **Why it made the list** - It won our main search, "best space heater", from 56 listings, and our search for "best space heater for bedroom", also from 56. - It uses fast ceramic heating made for indoor rooms and offices. - It has five modes, an adjustable thermostat, a 12-hour timer and a remote. **Drawbacks** - Its 10-inch body is made for smaller spaces. In our large-room search it lost to a bigger tower. **Skip it if** you need to warm a large or open-plan room. ### 2. Dreo 16-Inch Tower Space Heater for Large Rooms: best for large rooms **Why it made the list** - It won our search for "best space heater for large room", from 52 listings. - It is a 16-inch, 1,500-watt tower heater designed for large rooms. - It has an adjustable thermostat. **Drawbacks** - It takes more floor space than the compact Dreo. **Watch for this:** Dreo sells several similar 16-inch towers under different listings. Check the model name matches before you buy. **Skip it if** you only need to warm a small bedroom or a desk. ### 3. Lasko 751320 Ceramic Tower Space Heater: best for spreading heat across an open space **Why it made the list** - It was a runner-up in our large-room search. - It is a 23-inch ceramic tower, the tallest of our picks. - It oscillates widely to spread heat across open spaces, and it comes with a remote. **Drawbacks** - It did not win any of our searches. - At 23 inches tall, it takes the most room of our picks. **Skip it if** you want the smallest heater you can tuck under a desk. ### 4. Amazon Basics Ceramic Space Heater: best for simple dial controls at a desk **Why it made the list** - It was a runner-up in our main search. - It is a small ceramic heater with simple knob controls and a thermostat. - Its listing names both tip-over and overheat protection, and it has a lighter build than our top pick. - The Spruce also picks a small [Amazon Basics ceramic heater](https://twelvetabs.com/reviews/best-space-heaters/#pick-4), with a tip-over switch that is a button underneath. We could not confirm it is this exact listing. **Drawbacks** - It has no remote. - It has only basic high and low heat settings. **Skip it if** you want a timer, a remote or several modes. ## What we left out, and why Our three searches returned 164 listings. TwelveTabs shortlisted 30 of them, read the listing pages of 10 finalists, and named a winner and runners-up in each. We kept four heaters and left out these: - **The GiveBest Portable Space Heater**, a runner-up in our main and bedroom searches. It is a compact heater with manual dials, no remote and fewer settings, so it covers the same need as the Amazon Basics pick. - **A second Amazon Basics listing**, a runner-up in our bedroom search. It is the same heater as our pick 4. - **A second Dreo 16-inch tower**, a runner-up in our large-room search. It is the same brand and type as our pick 2. Wirecutter's top pick is the Vornado VH200. Two Amazon product lookups on September 25, 2026 turned up other Vornado heaters but not the VH200, so it is not in our table. ## Questions people ask ### Is it safe to leave a space heater on overnight? No. The Spruce's safety advice, drawn from the U.S. Fire Administration and FEMA, is to never leave a space heater running unattended, including overnight while you sleep. ### Can you plug a space heater into an extension cord? No. The Spruce says a heater plugged into a power strip or extension cord can overheat. Plug it straight into a wall outlet. ### Where should you put a space heater? On a flat, stable surface, not on a rug or carpet, with 3 feet of clear space from anything that can catch fire, such as curtains, bedding or furniture. ### What size space heater do you need for a large room? Compact heaters are best for warming one spot. For a large room, a tower like the [Dreo 16-inch](https://twelvetabs.com/reviews/best-space-heaters/#pick-2), which won our large-room search, is designed to cover more space. Keep any heater at 1,500 watts or less. ### How did TwelveTabs choose these space heaters?
