Top 10 Best Space Heaters (2021)

There’s no need to turn up the thermostat for the entire house when you have one of the best space heaters by your side. You’ll appreciate its usefulness this winter. Space heaters can raise an individual room’s temperature, provide direct heat, dry out singled-out areas, and prevent pipes from freezing—all without running up the electric bill.

Space heaters come in many sizes and styles, and we’ve reviewed plenty, from electric stoves with faux flame effects to oscillating towers. Many space heaters run on electricity and plug into the wall, while natural gas or propane tanks power most other models. You’ll also come across energy efficient models, ultra compact tabletop designs, and units with extra safety features.

We want to help you find your perfect fit. Here’s our list of top 10 bestselling space heaters:
