An electrical heating device is disclosed that is suitable to vaporize air treatment chemicals from an impregnated substrate. The device is provided with a PCT heater held between electrical contacts and a spring that is compressed between the housing of the heating device and one of the electrical contacts to maintain pressure thereon in spite of thermal expansion of the housing, ensuring good electrical contact between the PCT heater and the electrical contacts. La présente invention concerne un dispositif de chauffage électrique apte à la vaporisation de produits chimiques de traitement de l'air provenant d'un substrat imprégné. Le dispositif est équipé d'un réchauffeur PCT maintenu entre des contacts électriques et un ressort qui est comprimé entre le boîtier du dispositif de chauffage et un des contacts électriques pour maintenir une pression sur celui-ci malgré la dilatation thermique du boîtier, assurant un bon contact électrique entre le réchauffeur PCT et les contacts électriques.
