An electric heating boiler is a boiler equipment that utilizes electrical energy to convert it into thermal energy, which is then converted and outputted as steam, high-temperature water, or organic thermal carriers with certain thermal energy through the boiler. There are three types of heating methods for electric heating boilers: electromagnetic induction heating, resistance (electric heating tube) PTC ceramic semiconductor heating, and resistance heating. The resistance heating method is further divided into stainless steel heating tube electric boilers and ceramic heating tube electric boilers. The resistance heating method uses resistive tubular electric heating elements for heating, while the semiconductor type uses oxide semiconductor ceramic plates, ensuring complete separation of water and electricity.
