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.
