What Is a “Power Factor” And Why Is It So Important That It Is Close to Unity?

Power factor (cosφ) is a characteristic of any electrical product. Since in the induction boiler the heat exchanger is heated in a magnetic field, some part of the magnetic field is scattered, and the other part is used for heating. A power factor of 0.98 indicates that 98% of the variable magnetic field is involved in the heating of the heat exchanger and only 2% is lost. This is an extremely high indicator of system performance.
