Self-adaptive heating control method and device of water heater

The invention discloses a self-adaptive heating control method and device for a water heater, and the method comprises the steps: judging whether the real-time water outlet flow of a water outlet pipeline is smaller than a first water outlet flow threshold value or not when the water outlet pipeline of the water heater is discharging water; if yes, a first heater on a heating pipeline of the water heater is controlled to work so that the first heater can heat a heat transfer fluid medium flowing through the heating pipeline, and the heating pipeline is used for connecting the heat exchanger and a storage container storing the heat transfer fluid medium so that a circulation loop can be formed between the heat exchanger and the storage container; and a power pump on the heating pipeline is controlled to work, so that the power pump drives the heated heat transfer fluid medium to flow through the heat exchanger and transfer heat to tap water of the water outlet pipeline through the heat exchanger. Therefore, th
