台灣是日照量相當充足的國家，即使在緯度較高的北部，依然可以使用太陽能熱水器，但是第一代傳統型熱水器儲水桶與第二代改良型熱水器儲水桶的設計並不理想，當我們使用熱水時，一邊消耗熱水的同時會一邊補入冷水，造成儲水桶內熱水溫度明顯下降，必須另外使用電能輔助器進行加熱，因此提高其他能源的耗用。針對市售前二代儲水桶的缺點，我們設計第三代智慧型太陽能熱水器儲水桶來改善，我們在桶內部增加一可移動的「分隔圓盤」，幾乎可完全隔離熱水與冷水，洗澡時水溫不會下降，可以有效解決冷、熱水混合問題，使整個儲水桶的熱水接近100%完全被利用。

Taiwan is a country with quite adequate amount of sunlight; even at the northern highlands solar-powered water heater will still be usable. However, the first generation conventional storage water heater and the second generation improved storage water heater design are not an idea. When hot water is being used, the tank refills itself with cold water, and, thus, resulting in the decrease of water temperature inside tank. This will cause the heater to have an additional heating cycle, also to increase consumption of energy sources. As for the disadvantage of the second generation storage water heater, we have designed the third generation storage water heater, the smart solar water heating tank with a movable ＂partition disk＂ inside the tank, to improve and effectively resolve problem of mixing hot and cold water so that the hot water can be fully utilized.
