Some fan heaters are designed for bathroom use and are equipped with safety features like splash-proof casings. However, always check the product specifications to ensure it's suitable for bathroom use.

Fan heaters are a type of space heater. The primary difference is that fan heaters use a fan to distribute heat, while other space heaters may use different methods like radiant heating.

To clean a fan heater, unplug it, and wait for it to cool down. Use a soft brush or compressed air to remove dust and debris from the heating element and fan blades. Clean the exterior with a damp cloth.

It's generally not recommended to leave a fan heater unattended or running overnight, as this can pose safety risks. It's best to turn it off when you're not in the room or when you go to sleep.

Fan heaters are generally not the most energy-efficient heating options for large spaces. However, they can be extremely efficient for spot heating in smaller areas when used selectively.
