The invention discloses a heat pump system and a control method. A controller of the heat pump system is configured as follows: according to historical characteristic data of hot water used by a user within a preset historical duration, water use characteristic data of the user every day is determined, and the water use characteristic data comprises a water use period and the water consumption of the water use period; and in the adjacent non-water-use period before the water use period, the floor heating heating function and the water tank heating function are controlled according to the water use characteristic data, the number of indoor people and the floor heating water temperature, so that the water temperature of a water tank can be adjusted according to the water use habit of the user, the water temperature of the water tank can be controlled more accurately, the power consumption is reduced, and the user experience is improved. 本发明公开了一种热泵系统和控制方法，该热泵系统的控制器被配置为：根据用户在预设历史时长内使用所述热水的历史特征数据确定用户在每天的用水特征数据，所述用
