The best fan heaters do a quick job of shooting plenty of warmth around a room in your home, getting you up to a comfortable temperature in half an hour or less.

Fan heaters are typically light, portable, easy to set up and handy for speedy heating. 

Our tests found some much better than others, though. The worst fan heater we've tested warmed up our test room by less than half as much as the best. 

Discover which are the best fan heaters and how much each costs to run below.
