Household appliance for heating liquid

A method for manufacturing a household electrical appliance for the heating of liquid having a tank intended to contain the liquid to be heated, said tank having a heating element including an electrically insulating plate, said method comprising:

• producing a resistive track by silk-screening onto said electrically insulating plate;
• coating of said electrically insulating plate with at least one protective layer;
• producing a control device having a plurality of electronic components amongst which are at least one thermometric component, a switching component capable of opening or closing the power supply circuit of said heating element and a control component controlling said switching component in accordance with signals output from said thermometric component, said electronic components being connected by electrically conductive tracks whose production is also automated;
• wherein at least said thermometric, switching and control components are located on said electrically insulating plate within a single area free of resistive track, said area being surrounded by a peripheral zone free of resistive track and of electronic components.
