Fan-Forced Heater

A Fan-Forced Heater is the simplest electric heat sold: a nichrome resistance coil, a fan behind it, a bimetal thermostat and a plastic or steel shell. The coil glows near 1,300 degrees F and the fan throws that heat straight out, so a small bathroom becomes tolerable in two or three minutes. These sell for 20 to 40 dollars and weigh two or three pounds.

Refinement is what the low price buys away. Set against a Ceramic Heater, the exposed coil scorches dust in the air. That means these smell strongest on their first run, and bare wire at that temperature is a genuine ignition source if fabric reaches it. The fan is louder too, often above 55 decibels. An Oil-Filled Radiator or a Micathermic Heater keeps a room comfortable for hours after shutdown, while this one is comfortable only while it blows. Utility versions put the same mechanism in a steel case with a cage guard and a carry handle.

Bathrooms, entryways, a laundry room, a shed and any errand lasting ten minutes are where it works best, provided a bathroom model is marked by its maker for that use and plugged into a GFCI outlet. Do not run it as a room's main heat through a winter, and keep it away from sawdust, hay, solvent vapor and anything fabric, since an open glowing coil ignites what touches it. Anyone who needs quiet should look at a different style entirely.

Study the guard, then the switches. A closed grille that a small finger or a curtain edge cannot reach through is the main safety feature. A wide cage over an open coil is not that. Tip-over protection matters more here than on any silent design. A thermostat, even a crude dial, is worth the few extra dollars, because without one the heater runs flat out until you unplug it. Weight helps as well: a two pound unit walks across a smooth floor on its own vibration.

Clear dust and lint from the grille every few weeks, since lint resting against a glowing coil is how these fail badly rather than quietly. Give it a proper look before each winter and retire it at any sign of a browned housing, a stiff cord or a warm plug. Replacing one at five years is a sensible habit at this price.
