1. Principle of electromagnetic boiler: It works by induction of AC electromagnetism through internal coil. When the alternating magnetic field passes through the closed conductor, it will induce current, which will generate heat to achieve the purpose of cooking.

2. Principle of electric boiler: Using electric power as energy source, using resistance heating or electromagnetic induction heating, when the heat medium water or organic heat carrier (heat transfer oil) is heated to a certain parameter (temperature and pressure) through the heat exchange part of the boiler, the heat energy of a rated working medium is output for heating.

Second, the application of the two is different:

1. Application of electromagnetic boiler: used for cooking food in daily life.

2. Application of electric boiler: This kind of boiler is widely used for domestic hot water and heating in hotels, villas, factories, office buildings, government agencies, colleges and universities, hospitals, military units and other places with high appearance requirements.

Third, the structure of the two is different:

1. Structure of electromagnetic boiler: equipped with control panel, functional PCB board, induction coil, temperature sensor, etc. The shell is internally provided with a positioning heat insulation board with matching shapes. The glass plate is placed at the concave bottom of the positioning heat insulation plate and supports the pot body, and the edge of the positioning heat insulation plate is turned outwards to guide the liquid overflowing from the pot body out of the shell, and the bottom of the pot body is in contact with the temperature sensor.

2. Structure of the electric boiler: The main body of the electric boiler consists of a steel shell of the electric boiler, a computer control system, a low-voltage electrical system, an electric heating pipe, water inlet and outlet pipes and a detection instrument.
