PROBLEM TO BE SOLVED: To provide a water heater with a mist function capable of appropriately executing a mist operation and a hot water filling operation.SOLUTION: A water heater with a mist function includes a control section 11 for controlling a mist operation and a hot water filling operation by switching a target temperature of hot water generated by a heat source machine between a mist hot water supply temperature for the mist operation and a hot water filling hot water supply temperature for the hot water filling operation. When the execution of the mist operation is requested and the execution of the hot water filling operation is not requested, the control section 11 sets the target temperature to the mist hot water supply temperature to execute the mist operation, and when the execution of the mist operation is not requested and the execution of the hot water filling operation is requested, the control section sets the target temperature to the hot water filling hot water supply temperature to execute the hot water filling operation. When the execution of the mist operation is requested and the execution of the hot water filling operation is requested, the control section sets the target temperature to the hot water filling temperature to execute the hot water filling operation and puts the mist operation in the stand-by state without executing the mist operation.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】ミスト運転及び湯張り運転を適正に実行可能なミスト機能付給湯装置を提供する。【解決手段】熱源機で生成する温水の目標温度を、ミスト運転用のミスト給湯温度と、湯張り運転用の湯張り給湯温度とに切換えてミスト運転および湯張り運転とを制御する制御部11を備え、制御部11は、ミスト運転の実行が要求され且つ湯張り運転の実行が要求されていないとき、目標温度をミスト給湯温度に設定してミスト運転を実行し、ミスト運転の実行が要求されておらず且つ湯張り運転の実行が要求されているとき、目標温度を湯張り給湯温度に設定して湯張り運転を実行し、ミスト運転の実行が要求され且つ湯張り運転の実行が要求されているとき、目標温度を湯張り温度に設定して湯張り運転を実行するとともに、ミスト運転を実行せずに待機状態にする。【選択図】図1
