A portable heater is a compact heating device designed to provide warmth in specific areas of a home or office. Unlike central heating systems, which heat an entire building, portable heaters can be easily moved from room to room, making them convenient for targeted heating. They come in various types, including electric, propane, and infrared models, each with different features and heating capacities. These heaters are often equipped with safety features such as tip-over protection and overheat shut-off to prevent accidents. Many portable heaters also have adjustable thermostats and timers, allowing users to control the temperature and energy consumption effectively. Popular brands include Dyson, Lasko, and Honeywell.
