[0028] The combustion chamber assembly 40 includes a combustion shell 41 and a heat-insulating outer shell 42 wrapped around the outside of the combustion shell 41; an insulation region is formed between the heat-insulating outer shell 42 and the combustion shell 41; a first ventilation structure 421 is provided on the shell wall of the heat-insulating outer shell 42, and a second ventilation structure 411 is provided on the shell wall of the combustion shell 41; outside air can enter the interior of the combustion shell 41 through the first ventilation structure 421, the insulation region, and the second ventilation structure 411;

[0029] The fire bar burner 50 is arranged at the bottom of the combustion shell 41 . An ignition needle 51 and a sensing needle 52 are provided at a position of the combustion shell 41 close to the fire bar burner 50 .

[0030] In the present invention, the heat exchange component 30 is replaced with a flat heat exchange pipe 32 and heat exchange fin 33 structure, which saves the height space of the heat exchange water tank on the one hand, and utilizes the height space to arrange the combustion chamber component 40; on the other hand, the heat exchange pipe 32 and heat exchange fin 33 made of stainless steel can effectively improve the corrosion resistance of the heat exchange component 30, thereby increasing the service life of the gas water heater; and, the elevated combustion chamber component 40 replaces the space of the heat exchange copper water tank with its outer shell, reducing the material cost of copper and the manufacturing cost of the coil processing technology of the heat exchange copper water tank, thereby reducing the production cost as a whole; at the same time, the heat insulation area formed between the thermal insulation outer shell 42 and the combustion shell 41 can reduce the noise of combustion in the combustion chamber and the heat transfer to the outside, thereby improving the silent heat insulation performance of the burner.
