    • A water heater is provided in which neutralization process of drain is not required and an excellent heat efficiency is achieved. A route of exhaust gas which is passing through the main heat exchanger 18 is divided into a first exhaust gas chamber 23 having a secondary heat exchanger 19 and a second exhaust gas chamber 24 having a drain evaporator. Because of this, hot exhaust gas which is passing through only the main heat exchanger 18 flows into both the secondary heat exchanger 19 and the drain evaporator 100. Therefore, in the secondary heat exchanger 19 exhaust gas heat can be efficiently recovered by utilizing the hot exhaust gas, and in the drain evaporator 100 drain can be evaporated efficiently by utilizing the hot exhaust gas.
    • 提供一种热水器,其中不需要排水的中和过程并获得优异的热效率。 通过主热交换器18的废气的路线被分成具有二次热交换器19的第一排气室23和具有排水蒸发器的第二排气室24。 因此,仅通过主热交换器18的热废气流入二次热交换器19和排水蒸发器100.因此,在二次热交换器19中,可以通过利用热量有效地回收废气热 废气,并且在排水蒸发器100中,通过利用热废气可以有效地蒸发。
