The utility model provides a weather electromagnetic induction type electric heater auxiliary type solar water heating device, auxiliary heating device's energy memory is equipped with including powerdevice, conversion equipment, inside to and inductive control device. Wherein, power device conversion equipment and energy memory connects gradually, forms circulation circuit through the pipeline.With auxiliary heating device links to each other and to be equipped with inductive control device, but the weather forecast information at automatic reception night to the low ebb valence electricityintelligent control auxiliary heating device that the utilizes night liquid medium in to energy memory heats. Exactly because prior art lacks the inductive control device of this usable low ebb valence electricity intelligent control heating process, therefore it is higher to consume energy. Therefore, the utility model provides a solar water heating device is showing and has reduced the energy consumption, has realized the hydrothermal demand of lasting confession.
