Abstract

L'invention concerne un ensemble réservoir d'eau d'un dispositif de chauffage, et un dispositif de chauffage. L'ensemble réservoir d'eau comprend un corps de réservoir (10). Un premier ensemble de plaques latérales (17) définit des premières boîtes à eau (131), et un second ensemble de plaques latérales (18) définit des secondes boîtes à eau (141). Une entrée d'eau (132) est mise en communication avec une première boîte à eau (131), et une sortie d'eau (133) est mise en communication avec une première boîte à eau (131). La pluralité de premières boîtes à eau (131) et la pluralité de secondes boîtes à eau (132) sont mises en communication au moyen d'un ensemble de tubes d'échange thermique principal (20) et d'un ensemble de tubes de condensation (30). L'ensemble de tubes d'échange de chaleur principal (20) comprend des premiers tubes d'échange de chaleur (21). Le premier tube d'échange de chaleur présentant la température d'eau la plus élevée parmi la pluralité de premiers tubes d'échange de chaleur (21) comporte une section transversale de forme circulaire sans déflecteur.
