To prevent the occurrence of boiling in a hot-water heater of a work machine during a reduction in the flow amount.SOLUTION: The work machine includes a machine body, a work device provided on the machine body, an operator seat provided in the machine body, and the heating system for heating an area around the operator seat, the heating system having a heat generation part for generating heat with electric power, and a hot water circulation part for circulating water hotted by the heat generation of the heat generation part, the hot water circulation part having a flow control valve for controlling the flow amount of hot water with a change in the opening. The heat generation part changes the heat generation amount according to the change in the opening of the flow control valve.SELECTED DRAWING: Figure 7 【課題】作業機の温水ヒータにおける流量減少時の沸騰の発生を防止する。【解決手段】作業機は、機体と、前記機体に設けられた作業装置と、前記機体に設けられた運転席と、前記運転席の周囲の暖房を行う暖房装置と、を備える。前記暖房装置は、電力によって発熱する発熱部と、前記発熱部の発熱により温められた水を循環させる温水循環部と、を有する。前記温水循環部は、開度の変更により温水の流量を調整する流量調整弁を有する。前記発熱部は、前記流量調整弁の前記開度の変更に応じて、発熱量を変更する。【選択図】図７
