Control method and device of water heater, computer equipment and storage medium

The invention relates to a control method and device of a water heater, computer equipment, a storage medium and a computer program product. The method comprises the steps that the upper temperature of the water heater is obtained; whether the upper temperature is larger than a first temperature or not is determined, if yes, the heat pump heating system is closed, and electric auxiliary heating control is started; the lower temperature of the water heater is obtained; determining a comparison relationship between the lower temperature and a preset threshold value; and according to the comparison relation, the electric auxiliary heating system is started or closed. By means of the method, the water using requirement of a user can be met when the temperature difference between the upper portion and the lower portion of the water heater is large, and the energy-saving effect can be achieved. 本申请涉及一种热水器的控制方法、装置、计算机设备、存储介质和计算机程序产品。所述方法包括：获取所述热水器的上部温度；确定所述上部温度是否大于第一温度，若是，关闭所述热泵加热系统，开启电辅热加热控制；获取所述热水器的下部温度；确定所述下部温度与预
