When the cold weather rolls around, your heating system may need a little extra help to warm up your space. If you’re tired of chattering teeth or want to save money by heating just a portion of your space, the best small space heaters are a quick and effective way to boost the temperature in your chilly home or office. But before you buy a space heater, there are a few factors to consider, especially if you’re shopping for a more compact room.


When thinking about the space heater that is best for your needs, pay attention to the size of the unit. If you’re looking to heat up the area just around your desk at work, for example, then you’re going to want to pick a space heater that has a pretty small footprint (probably 6 inches or less). And if you’re looking to warm a slightly larger space (like a whole room), be on the lookout for a unit that can handle a more substantial area. I also included a tower-style heater on this list, which mainly takes up vertical space without impeding too much on your horizontal square footage.


A heater that puts out 1,500 watts max (on high heat) should work fine in most small rooms. I included one pick here that puts out a lower wattage, but it’s still a nice option for providing a little extra heat under your desk.


Space heaters, when used improperly, can be dangerous. That’s why it’s really important to avoid risky space heater mistakes and look for units that have safety features like overheat protection (which automatically turns the unit off if it gets too hot). Don’t worry, though — all of the picks listed here have the basic safety functions.

Additional features

Some space heaters are quite simple; the unit may have just an on/off switch or basic heat settings. Others boast some cool features, like a timer or remote control.
