Afin d'atteindre cet objectif, le chauffe-eau à gaz de la présente invention comprend : une conduite d'eau directe (111) pour l'écoulement d'eau directe; un capteur de débit (120) qui est monté sur la conduite d'eau directe (111) et mesure le débit de l'eau directe; un échangeur de chaleur (130) qui effectue l'échange de chaleur de l'eau directe, qui traverse le capteur de débit (120), par la combustion d'un brûleur; une conduite d'eau chaude (112) à travers laquelle de l'eau chaude chauffée au niveau de l'échangeur de chaleur (130) s'écoule; une vanne de régulation du débit (140) qui est montée sur la conduite d'eau chaude (112) et régule le débit de l'eau chaude à évacuer; et une conduite de dérivation (113) raccordée à un élément d'embranchement d'eau directe (114) et à la conduite d'eau directe (111) à une extrémité latérale et à un organe de mélange d'eau directe et d'eau chaude (115) et à la conduite d'eau chaude (112) à l'autre extrémité latérale. Le chauffe-eau à gaz de la présente invention se caractérise en ce qu'une vanne d'ouverture et de fermeture (150), une pompe (160) et une vanne à trois voies (170) sont montées sur la conduite de dérivation (113), la vanne d'ouverture et de fermeture (150) régulant le débit d'eau s'écoulant à l'intérieur de la conduite de dérivation (113), la pompe (160) faisant circuler l'eau dans la conduite, et la vanne à trois voies (170) possédant une ouverture configurée de façon à raccorder deux quelconques des trois voies.
