Abstract

L'invention concerne un appareil offrant un chauffe-eau à bras latéral de condensation présentant un rendement amélioré. L'élément de bras latéral de condensation recycle les gaz d'échappement pour chauffer la partie plus froide d'un réservoir de chauffe-eau en recourant à l'effet de thermosiphon (ou de flottabilité) dans une configuration à contre-courant, augmentant ainsi le rendement du chauffe-eau.
