摘要

The device has a throughflow heater (12) whose power is regulated for constant temp. at the heater outlet. The fresh water to the shower passes through a heat exchanger (8) in the shower water outlet line (5) to pre-heat it. The rated current of the throughflow heater is higher than the permitted continuous current of the electrical feed line (16) and the series protection element (17). A current limiting circuit (15) regulates the current drawn by the heater at least down to the permitted continuous current during each starting phase within a predefined period, matching the heating time constant of the electrical feed line and protective device.
