The invention relates to an instantaneous water heater (D) comprising a heating module (H) provided with at least one assembly of heating bodies (K, K1, K2), a rotatable actuator (L) for preselecting a heating power, at least one stationary electric switching system (S), and a sliding system (A) which is linearly displaceable according to a flow and actuates the switching system (S). The inventive instantaneous water heater is characterised in that the sliding system (A) is rotatable and connected to the actuator (L), the switching system (S) is provided with only one switching element (3, 4, 3') for the assembly of heating bodies and the sliding system (A) is embodied in such a way that each heating power is pre-selectable only by adjusting the rotation position of the sliding system (A) with respect to the switching system (S) and can be called by the displacement of the sliding system. |
