A coiled heater is a type of electric heater that uses a coiled wire to generate heat. The coiled wire is usually made of copper or other metal and is heated by an electric current. The heat generated by the coiled wire is then transferred to the surrounding air, providing warmth to the room. Coiled heaters are often used in residential and commercial settings, as they are an efficient and cost-effective way to heat a space. Coiled heaters are also often used in industrial settings, such as factories, where they can provide a more efficient way to heat large areas. Coiled heaters are generally considered to be a safe and reliable source of heat, as they are designed to prevent overheating and other safety hazards.
