A space heater is a portable device designed to heat a small area or room. Unlike central heating systems that warm an entire building, space heaters provide localized warmth, making them energy-efficient for individual use. They come in various types, including electric, gas, and infrared models, each with different heating methods and features. These heaters are commonly used during colder months to supplement existing heating systems or to heat specific areas like bedrooms or offices. Safety features, such as tip-over protection and overheat shut-off, are important considerations when choosing a space heater to ensure safe operation in homes.
