The invention discloses a control method of a liquid heater and the liquid heater. The control method comprises the steps that the heating requirement of a whole vehicle heat management controller is received; determining the output power of the liquid heater according to the heating requirement; and the corresponding number of IGBT switches are controlled to be started according to the output power, so that the cooling liquid is heated. In the application, the liquid heater outputs the fixed power corresponding to the heating requirement, so that the influence caused by current fluctuation is avoided.
