Portable heaters are compact devices designed to provide warmth in specific areas of a home or office. They come in various types, including electric, propane, and infrared models, allowing users to choose based on their heating needs and preferences. These heaters are easy to move from room to room, making them ideal for spot heating in spaces that may not have central heating. Many portable heaters feature safety features such as tip-over protection and overheat shut-off to prevent accidents. They are often used during colder months to supplement existing heating systems or to heat small spaces efficiently, helping to save on energy costs.
