The invention provides an instant water heater. The instant water heater comprises a shell and a heating module. The heating module comprises a cold water channel, a hot water channel and a hot water tank; the cold water channel is connected with the tap water source; a water inlet of the hot water channel is communicated with a water outlet of the hot water tank, and a water outlet of the hot water channel is connected with a water inlet of the hot water tank; heat exchange is realized between the cold water channel and the hot water channel; and a heat exchange starting device for starting the heating module on the basis of water flow in the cold water channel is further arranged. The invention further provides a control method of the instant water heater. Through the structure and the method, control over the hot water outlet flow of the hot water tank is achieved through the method, the actual hot water temperature requirement is met, and regulation and control over the outlet water temperature of the ins
