8 Best Space Heaters (2026): Tested, Measured, and Mistreated
The Best space heaters are winter’s rear guard, the last line of defense against goose bumps and cold feet. Though not a great way to heat a whole home, space heaters can be indispensable for a late-evening movie night, a workbench in a chilly garage, or the home’s odd corners that refuse to stay warm. And if you live in an apartment building where you don’t control the heat, they may be your only way to feel OK in January.
Even so, these little machines do bring about serious safety and reliability concerns, along with a need to be able to parse dodgy and opaque marketing claims. (For example, no matter what the marketing specifies, large space heaters usually aren’t more powerful or more effective than small ones.) So we turned down the thermostat and tested dozens of space heaters to find the ones that’ll warm you up as quickly, quietly, and safely as possible.
Alongside naming the top pick overall—the blessedly balanced and quiet Dreo Whole Room Heater 714—we also pinpointed which heaters are best poised to suit specific needs, from the best bathroom heater and a space heater that doubles as an air purifier to an option that’ll warm your towels. For those on a tight budget, the bare-bones Honeywell 360 Surround often goes on sale.

This Dreo is the best answer to what I’ve been looking for in a space heater ever since I started testing them. I want simple things: the promise of safety, with reliable tip-over and overheat protections; quiet and effective functioning; and the ability to use the full capacity of an American outlet to heat quickly and evenly around the room. I like a remote control, but if I lose it, I still want to be able to use the heater. I also like precise digital-temperature control, with a thermostat that actually works. I also don’t want to hate how the thing looks, considering it’ll be with me all winter.
The Dreo Whole Room Heater 714 checks these boxes better than any other heater among the dozens I’ve tested in the past two years—with thoughtful design touches that make it possible to actually like the thing. It’s a nice modern update on the classic fan design, able to oscillate not just side-to-side but also up and down. The counter-spiral grill, similar to competitor Vornado’s models, creates good heat distribution around the room. And while it’s not silent, it’s still quieter than my refrigerator on high fan speeds.
The thermostat works, a strangely rare quality among space heaters. This model is successful, I suspect, largely because its bipartite design allows the temperature sensor to be isolated from the heating elements. Huzzah! Other nice touches include buttons whose beeps are mutable and digital screens that dim themselves. The housing is satisfyingly cool to the touch. The heater also remembers its settings from previous use, so you don’t have to reprogram it each time you turn it back on. Oscillation is silent, with no squeaks, and the brushless fan is whistle-free.
It’s not perfect, of course. I’d like the ability to set a shutoff timer, and the on-device controls are a bit hard to see and close to the floor. There’s also one hot spot on the exhaust grill: the exact center where the Dreo logo sits. (Vanity is a vice!) Still, this is a great little heater. —Matthew Korfhage
