However, since the heat-insulating effect of the circulation pipeline of the user's home is inconsistent, there are two states of good heat-insulating effect and poor heat-insulating effect. When the heat preservation effect is good, the water temperature in the circulating pipeline of the water heater is reduced slowly, the temperature sensor in the water heater detects low water temperature, so that the zero cold water circulating function is started, but the water temperature in the actual circulating pipeline is higher, so that heat energy is wasted, water in the circulating pipeline flows circularly, and heat dissipation is accelerated; when the heat preservation effect is poor, the temperature in the circulation pipeline is reduced faster, the temperature sensor in the water heater detects high water temperature, and the starting condition of the zero cold water circulation function is not reached, but at the moment, a user can feel that the water temperature is insufficient when using hot water.
