The utility model is used to provide instant hot water. Therefore, the utility model sets the above-mentioned convection barrel 50 as shown in Figures 7 to 9, and its outer diameter is set slightly smaller than the inner diameter of the heating tube 40, so that the convection barrel 50 is connected to the inner diameter of the heating tube 40. The flow channel space 80 between the heating tubes 40 shrinks (the spacing is about between 5-8mm), and the height (length) of the convection bucket 50 is about the length heated by the electrothermal film 43 in the heating tubes 40. Therefore, the utility model is heating The design of the convection barrel 50 inside the tube 40 enables the formation of a thinner channel space 80 inside the heating zone 42, reducing the internal water storage capacity of the channel space 80, thereby reducing the heat transfer distance and achieving the purpose of rapid heating.
