常に清潔に貯水を確保することが出来る。Since the present invention is configured as described above, when the water heater is not used for a long time, the electric drain valve 7 is automatically opened to drain water by counting the unused time, and the electric water supply valve 6 is automatically opened to supply water. Since this is a system that automatically replaces new water, there is no need for manual intervention, and even if the tank 1 is absent for a long time, the hot water in the tank 1 will not spoil and a clean water supply can always be ensured.
また、この清潔さ、タンク１の容量その他の事情に応じ
て自動入れ替えを行う未使用時間、排水時間及び給水時
間を自由に設定することができる。Further, depending on the cleanliness, the capacity of the tank 1, and other circumstances, it is possible to freely set the unused time, drain time, and water supply time for automatic replacement.
更に、温水の消費１に応じて給水され常に所定量の貯水
