Convection heaters are devices that warm up a space by circulating air. They work by heating the air around them, which then rises and creates a flow of warm air throughout the room. This process is known as convection, where warm air moves up and cooler air moves down to be heated, creating a continuous cycle. These heaters can be powered by electricity, gas, or oil, and are often used in homes and offices for efficient heating. Convection heaters come in various forms, including baseboard heaters and portable units, making them versatile for different heating needs.
