L'invention concerne un chauffe-eau (500) thermodynamique, notamment d'une capacité de 400 litres, comprenant un circuit caloporteur formant pompe à chaleur, comportant : a. un circuit basse pression comprenant un évaporateur (508); b. un circuit haute pression comprenant un condenseur (100) en contact avec la cuve (502) dudit chauffe-eau, caractérisé en ce que ledit condenseur comprend : bi. deux plaques superposées et plaquées l'une contre l'autre, l'une des plaques comprenant un bossage continu formant, en coopération avec l'autre plaque, un conduit réalisant un circuit de condensation selon des canaux parallèles ; bii. une entrée (110) du fluide frigorigène, en phase gazeuse, selon un canal unique suivie d'une zone (111) de distribution comprenant une pluralité de bifurcations de division, répartissant chacune le fluide véhiculé d'un canal de section courante dans deux canaux de même section courante ; biii. une sortie (120) selon un canal unique du fluide frigorigène en phase liquide, laquelle sortie est précédée d'au moins une zone de regroupement comprenant une pluralité de bifurcations de concentration, ladite zone de regroupement regroupant N canaux de même section courante en ([N/2]+ 1) canaux de même section courante. The invention relates to a thermodynamic water heater (500), in particular having a capacity of 400 litres, including a heat-transfer circuit forming a heat pump, comprising: a. a low-pressure circuit including an evaporator (508); b. a high-pressure circuit including a condenser (100) in contact with the tank (502) of said water heater, characterised in that said condenser includes: bi. two vertically adjacent plates pressed against one another, one of the plates including a continuous boss forming, in engagement with the other plate, a duct forming a condensation circuit along parallel channels; bii. an intake (110) for the refrigerant fluid, in gaseous phase, along a single channel, said intake being followed by a distribution area (111) including a plurality of dividing bifurcations, each distributing the carried fluid from a channel having a current cross-section into two channels having the same current cross-section; biii. an outlet (120), , for the refrigerant fluid, in liquid phase, along a single channel, said outlet being preceded by at least one grouping area including a plurality of concentrating bifurcations, said grouping area grouping N channels having the same current cross-section into (I) channels having the same current cross-section.
