摘要
A method for producing hot water and a device especially for carrying out the method are provided. The method utilizes combined heat resources of solar energy and heat pump in the manner of heating water at multiple stages and storing accumulating energy. The device comprises a solar energy collector, a heat pump, an electrical heater, a water tank and a control unit. The device also includes water-heating tanks with multiple stages. A heating means with multiple stages at different temperatures is formed either by the solar energy collector or by the collector and the heat pump. The outputting end of the two or more heating stages constituted by the solar energy collector or by the collector and the heat pump is connected through ducts to the corresponding water-heating tanks. A predetermined amount of produced water heated in multiple stages is respectively stored in the water-heating tanks. Compared with the prior art, the present invention is endowed with the performance of making use of the solar energy to the greatest extent and utilizing off-peak electricity more efficiently as a supplementary heating means. Furthermore, the arranging fee of the device is reduced and its adaptation of mounting is improved.
