The Kissair space heater gives you a lot of bang for your buck. You might not expect much from a portable heater that's less than 10 inches high, but shoppers confirm that it warms up a small room fast and effectively. At just $22, it's a steal — it usually costs $60. Oh, and did we mention that it doubles as a fan, so you can use it year-round?

Dreo’s Ceramic Space Heater is on sale for $75, which is 50% off the retail price of $150. An extra heater is great to have on hand when the temperature drops and shoppers love this one—it has almost 300 five-star reviews—with many often commenting on how “easy to use” the heater is and that it is “whisper quiet” when running.

So many of us rely on space heaters to keep ourselves warm during the winter months. Spots in your home where your heating system doesn't reach can be easily supplemented with a portable heater, and they can also help you save on energy bills.
