A seat heater (10) with a heating element (12) connected between a first (14) and a second (16) nodes comprises a third (18) and a fourth (20) node operatively connectable to a first and a second terminal, respectively, of a power supply. A first electric component (22) providing a controllable first conductance is connected between the first and the third nodes. A second electric component (24) providing a controllable second conductance is connected between the second and the fourth nodes. A control network (26) is connected to the electric components to control the respective conductances and has a mode of operation in which it applies an oscillating signal to the heating element by modulating the first and second conductances in such a way that a voltage drop variation between the third and first nodes is opposite to a voltage drop variation between the second and fourth nodes.
