Abstract
The invention relates to an electric fluid heating device (1) comprising: at least one fluid inlet (7), at least one fluid outlet (11), at least one heating element (13), at least one first temperature sensor (21) for measuring the temperature of said at least one heating element (13), and a control module (15) of the at least one heating element (13). According to the invention, the device (1) comprises at least a second temperature sensor (23) for measuring the temperature of the fluid at the at least one outlet (11), and the control module (15) comprises at least one processing means (17, 19, 35) for: using the temperature information (T21, T23) from the temperature sensors (21, 24), and for generating a command for the at least one heating element (13) according to the temperature information (T21, T23). The invention also relates to an associated heating circuit and method for managing the temperature.
