Plug-in heaters vs. portable floor heaters

Floor heaters have cords that can be a trip hazard and take up floor space. Wall-plug heaters are smaller and stay out of the way, but are meant for smaller rooms. If you mainly need warmth in a bedroom, bathroom or office, a plug-in model is often the tidier choice.

Using it safely

Plug it straight into a wall outlet — never an extension cord or power strip — and keep about 3 feet of clear space in front of it.
