A space heater is a portable heating device designed to warm a specific area or room rather than an entire building. They come in various types, including electric, gas, and propane models, and are often used to provide extra warmth during cold weather. Space heaters are popular for their convenience and energy efficiency, as they allow users to heat only the spaces they occupy. Most space heaters feature adjustable temperature settings and safety features like automatic shut-off to prevent overheating. They are commonly used in homes, offices, and workshops, making them a practical solution for localized heating needs. Proper usage and maintenance are essential to ensure safety and efficiency.
