WATER HEATER OF ENDORSEMENT WITH IONIZED IGNITION AND ELECTRONIC CONTROL OF TEMPERATURE, FOR SOLAR HEATERS OF THE TYPE THERMOSIPHON

摘要

A backup water heater for a solar water heater operates by means of an electronic card that initiates the operation of the heater in response to temperature and flow signals. A burner is lit gradually by an electrical spark emitted by a spark plug connected to the electronic card, which 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 water heater.
