Abstract

La présente invention concerne un chauffe-eau électrique écologique instantané à accumulation comprenant un réservoir d'eau, un tube d'arrivée d'eau, un tube de sortie d'eau, un élément chauffant, un thermostat de régulation de la température de l'eau, et un coupe-circuit anti-surchauffe, ainsi qu'une soupape de sûreté en cas de surchauffe ou surpression. Le fond du réservoir d'eau est équipé d'un collecteur de chaleur de rayonnement, d'un tuyau absorbant la chaleur de rayonnement, un tube d'injection directe d'eau chaude, une buse d'injection directe d'eau chaude, ainsi qu'un raccord universel. Etant donné que le chauffe-eau n'a pas besoin de préchauffage, comme dans le cas d'un chauffe-eau instantané, le chauffe-eau peut fournir de l'eau chaude dès qu'iI est alimenté, sans perte d'énergie thermique, et peut améliorer le rendement énergétique, et jouer un rôle positif dans la protection de l'environnement de la société. Une fois que le chauffe-eau est préchauffé, la quantité d'eau chaude disponible augmente d'au moins une fois par comparaison avec celle de chauffe-eau conventionnel. La présente invention met à mal le concept que les rendements structurels et les utilisations des chauffe-eau instantanés et des chauffe-eau à accumulation, avec une histoire de presqu'un siècle, doivent être pris séparément les uns des autres. L'invention vient à bout également des inconvénients selon l'état antérieur de la technique, ce qui fait que la présente invention modifie les critères permettant d'affirmer que les chauffe-eau électriques instantanés ne peuvent s'utiliser que dans des systèmes d'alimentation électrique de grandes dimensions.
