But, its shortcoming just becomes so obvious in the occasion that uses more frequently, because the mode of hot water supply of gas water heater of prior art is to heat while using. If you turn off the gas water heater in the middle of bathing (the gas water heater is usually turned off when using soap), and when you turn it on again, a small amount of hot water will flow out, and then the water temperature will cool down rapidly. It will take a long time for hot water to flow out again. In order to make the hot water flow out as soon as possible, the user often adjusts the hot water to the maximum, and in this case it is very easy to cause accidental burns, and this situation often occurs in winter.

A heat exchanger 9 is respectively provided on both sides of the shell 22 , and one end of the leg 2 b extends out of the shell 22 and is mated with the corresponding heat exchanger 9 . Such an arrangement enables the heat exchanger to transfer heat to the water pipe through the legs and the heat exchange strip faster when the heat exchanger is heated, thereby accelerating the increase of the water temperature in the water pipe. At the same time, the fine sand can also be heated. When the gas water heater is turned off, the fine sand can keep the water stored in the water pipe warm. The water temperature in the tank will not be too low.

A burner 7 is connected to the bottom of the combustion chamber 8, and the combustion port on the top of the burner 7 extends into the combustion chamber 8, so that the serpentine water pipe in the combustion chamber 8 and the heat exchanger thereon are heated.
