Abstract

Appareil de chauffage de fluide servant à chauffer un fluide et méthode d'utilisation de l'appareil. L'appareil de chauffage de fluide comprend un élément chauffant servant à chauffer le fluide qui l'entoure et un circuit de commande relié à l'élément chauffant et pouvant être relié à une source d'énergie. Le circuit de commande comprend un trajet de courant allant de la source d'énergie jusqu'à l'élément chauffant et de nouveau vers la source d'énergie. Le circuit de commande comprend aussi un interrupteur relié au trajet de courant et un capteur de courant. La méthode comprend le déclenchement d'un mode chauffage dans l'appareil de chauffage de fluide, le déclenchement d'un mode de non-production de chaleur dans l'appareil de chauffage de fluide, la mise en tension de l'élément chauffant en mode de non-production de la chaleur, la détection d'un courant de fuite de l'élément chauffant pendant la mise en tension et la détection de la dégradation de l'élément chauffant selon le courant de fuite détecté.
