The invention provides a constant-temperature electric heating faucet. The faucet comprises a faucet body, a water flow control switch, a flow sensor, an operational amplifier, a comparator, a UC3842 controller and a flyback converter, wherein the flow sensor is arranged at a water inlet and outputs a real-time water pressure signal; the operational amplifier is connected to an output end of the flow sensor and performs power amplification on the water pressure signal; the comparator compares the water pressure signal with a reference value; a feedback end of the UC3842 controller is connected to an output end of the comparator and outputs a PWM (pulse width modulation) signal with an adjustable pulse width according to a comparison result; and a control end of a switching tube of the flyback converter receives the PWM signal, and an output end of the flyback converter is connected with an electric heating tube.
