The heater is an efficient heating device that converts electrical energy into heat energy. It is mainly used for temperature regulation in local spaces and is commonly used in homes, offices, and industrial scenarios. Its core is composed of an air heater and a fan. The air is heated by an electric heating element and sent out by the fan to achieve rapid heating. The equipment is usually equipped with PTC ceramic heating elements, vortex air ducts, or spiral finned tube heaters, supporting dual-mode cooling and heating, intelligent constant temperature, and safety protection functions (such as tilting power-off, overheating protection). Users can choose from desktop, vertical, or wall-mounted styles, which are convenient to operate and combine energy saving and comfort.
