Abstract
A seat heater, e.g. for a vehicle seat, comprises a heating element (10) for dissipating heat when a heating current flows across it and a temperature sensor (15) for providing a temperature signal indicative of the seat temperature. The seat heater comprises a common mode choke (16) with at least three windings. The heating element is connected in series between a first (16.1) and a second (16.2) thereof so as to be operatively connectable to a power source (12) via the common mode choke. The temperature sensor is connected to a third winding (16.3) of the at least three windings in such a way that the temperature signal may be received, e.g. by a temperature controller of the seat heater, via the third winding of the common mode choke.
