In the case of a water heater used in a vending machine for hot cup beverages such as hot coffee, the suction port of the hot water pipe is placed near the surface of the water, where the temperature rises quickly in the hot water storage tank, in order to be able to start selling immediately after the power is turned on. It is fixed, and when a hot water supply signal is received, it drives the hot water pump or opens the hot water supply electromagnetic valve to heat the hot water near the water surface in the hot water storage tank. The water level in the hot water storage tank is maintained within a certain range by using a ball tap or a level switch to open and close the water supply solenoid valve.
