Abstract

La présente invention concerne un dispositif de chauffage d'eau instantané. D'après un exemple de mode de réalisation de la présente invention, un dispositif de chauffage d'eau instantané comprend : un logement creux relié à un trajet d'écoulement ; au moins une unité de chauffage disposée longitudinalement dans le logement de façon à chauffer un fluide traversant le logement ; et une unité de commande conçue pour commander le fonctionnement de l'unité de chauffage. L'unité de chauffage est d'un type enroulé en spirale dans lequel un élément de chauffage plan est enroulé plusieurs fois de manière à ce que le fluide puisse le traverser.
