Zusammenfassung:To provide a water heater which can stabilize hot water supply even when water pressure is low.SOLUTION: A process that a water heater performs includes the steps to: detect that hot water supply with the water heater is stopped (S510); read out a set temperature for the hot water supply from a memory (S520); calculate a target opening of a total water volume servo on the basis of the read set temperature (S530); transmit a command to set an opening of a flow passage, from the total water volume servo to a heat exchanger, to the target opening to the total water volume servo (S540); and rotate a stepping motor of the total water volume servo in response to the command (S550).SELECTED DRAWING: Figure 5 【課題】低水圧時においても給湯が安定する給湯装置を提供する。【解決手段】給湯装置が実行する処理は、給湯装置による給湯が停止していることを検知するステップ（Ｓ５１０）と、給湯の設定温度をメモリから読み出すステップ（Ｓ５２０）と、読み出した設定温度に基づいて、トータル水量サーボの目標開度を算出するステップ（Ｓ５３０）と、トータル水量サーボから熱交換器に流入する経路の開度を上記目標開度にするための指令を、トータル水量サーボに送るステップ（Ｓ５４０）と、トータル水量サーボのステッピングモータが、当該指令に応答して移動するステップ（Ｓ５５０）とを含む。【選択図】図５
