In a hot air heater, heating wires 3a and 3b are wound around an insulating fire-resistant substrate such that electric current running through the heating wires 3a and 3b travels in opposite directions to cancel out electromagnetic waves generated by the heating wires 3a and 3b, thereby reducing the electromagnetic waves emitted from the hot air heater.
Chauffage d'air chaud comprenant des fils chauffants (3a, 3b) enroulés autour d'un support résistant au feu isolant de manière à ce que les courants traversent en sens inverse les fils chauffants (3a, 3b) pour compenser les ondes électromagnétiques engendrées par les fils chauffants (3a, 3b), réduisant ainsi les ondes électromagnétiques.
