A water heater is controlled by an electronic system that initiates the operation of the heater when a flow detector sends a demand signal for hot water flow to the electronic card, which ignites a burner as function of a temperature programmed by the user. The burner is lit gradually by an electrical spark emitted by a spark plug connected to the electronic card, which in turn controls gas feed to the burner. As soon as the burner is lit, the electric current generated by the first spark plug is transformed by the ionization effect, changing the polarization of the current, which is detected by another spark plug that emits the change signal to the electronic card for further control of the heater. The heater operates without a permanently lit pilot light.
