Some quietly warm a whole room, while others are cheap personal heaters for a desk or a quick blast of warmth. Here are our five favorites and who each one is for.

Frequently Asked Questions
Are space heaters safe to leave on?
Modern heaters with tip-over switches, overheat protection and cool-touch housings are much safer, but you should still never leave one running unattended for long periods or overnight without supervision. Keep them on a hard, flat surface away from flammable materials and plug them directly into a wall outlet, not a power strip.
Which type of space heater is most efficient?
For a person or small area, a focused ceramic or personal heater is most efficient because it heats only what you need. For an entire room, a heater with a thermostat and good circulation, like the Vornado models, maintains warmth more efficiently than one that runs at full blast constantly.
How big a room can a space heater heat?
Most 1500-watt space heaters can comfortably warm a room up to about 150–300 square feet. For larger or drafty rooms, choose a model with strong circulation and a thermostat, and remember space heaters are meant to supplement, not replace, central heating.
