The invention discloses a control method of a water heater. The control method comprises the following steps that S1, the water heater enters a full-time heat preservation mode; s2, the standby time tb of the water heater, the program pump shutdown time ts1, the real-time outlet water temperature Toutlet, the outlet water temperature mean value and the preset heat preservation value are obtained; and S3, whether the standby time tb is larger than the program pump shutdown time ts1 or not and whether the real-time water outlet temperature T < outlet > is smaller than the difference value of the water outlet temperature mean value and the heat preservation temperature value or not are judged, if yes, the water heater is switched to the preheating working mode, and if not, the water heater is kept in the full-time heat preservation mode. Full-time heat preservation is carried out after preheating is completed, the influence of abnormal water temperature is eliminated, the water temperature comfort is ensured whe
