PROBLEM TO BE SOLVED: To provide a mist type bathroom heating device capable of securing supply of hot water from a water heater even when the setting of atomization flow is lower than a minimum quantity of working water of the water heater, and suppressing wasteful water consumption.SOLUTION: A control means 24 controlling a flow by a main opening and closing valve 21 and an auxiliary opening and closing valve 22 restricts a flow to achieve a spray flow of more than the quantity of working water of the water heater when the spraying is started, and the restriction of the flow is released after a spray time has passed by a prescribed time from the start of spraying. The supply of hot water from the water heater can be secured, as the water heater is operated at the time of starting the spraying, and the water heater continues its operation even when the quantity of hot water supply becomes less than the quantity of water for starting the operation, once the operation is started. Further, as the spray flow is kept at the set flow after the lapse of the prescribed time, the wasteful water consumption can be suppressed.COPYRIGHT: (C)2009,JPO&INPIT【課題】噴霧流量の設定が給湯器の最低作動水量以下でも給湯器からの温水の供給を担保し、且つ無駄な水消費を抑えるミスト式浴室暖房装置の提供。【解決手段】主開閉弁21,副開閉弁22による流量制御を行う制御手段24は、噴霧開始の時点において、噴霧流量を給湯器の作動水量以上となるように流量規制を行い、噴霧開始の時点から噴霧時間が所定時間を経過した後に流量規制を解除するようにした。これにより、噴霧開始の時点に給湯器が作動し、一旦作動を開始すると、給湯量が作動開始水量以下となってもそのまま作動し続けるため、給湯器からの温水の供給は担保される。また、所定時間の経過後は噴霧流量が設定流量とされるため、無駄な水消費を抑えることができる。【選択図】図2
