The energy-saving preheating structure provided by the utility model is aimed at allowing a user to set the single circulating preheating water quantity, so that invalid and unnecessary repeated preheating are avoided.
The use mode is as follows:
And 1, opening the furthest-end tap, simultaneously pressing a button on an operator, starting timing (t 0) in the water heater, and monitoring the current water flow in real time.
And 2, when the furthest tap starts to discharge hot water, the button on the operator is pressed again, and the timing is finished (t 1).
And 3, calculating the water quantity L flowing in the time period t 0-t 1, namely the water quantity from the point A to the point B in the water pipe, according to the time length and the real-time water flow meter, and memorizing the result in the MCU.
And 4, when all the taps are in an unopened state, and when a temperature sensor in the water heater detects that the water temperature in the pipeline is lower than a certain value below a set temperature, automatically starting a circulation mode to heat the water in the pipeline.
And 5, automatically stopping heating after the water with the L flow is heated. Therefore, energy sources such as fuel gas consumption and the like for heating the water quantity from the furthest tap in the pipeline to the water return pipe (C point, D point and E point) can be saved.
