Best Space Heaters Under $40 Ranked

11 space heaters at a checked price under $40.

Last updated: November 11, 2026

Under $40 buys the basics: small ceramic fan heaters and compact tower models that warm a desk, bathroom or small bedroom. Nearly all draw the same 1,500 watts at most, so heat output is similar to costlier models, but the controls are simpler and the build and thermostat accuracy are less refined.

Look for tip-over and overheat shutoff, a certified listing from a recognized safety lab, and a thermostat rather than just a high-low switch. Plug directly into the wall and never an extension cord. Check noise levels, because cheap fans can be loud, and remember that a small heater warms a small space only.
