Novel gas water heater

The utility model discloses a novel gas water heater which comprises a shell, a combustor, a gas pipeline and other components, the combustor, the gas pipeline and the like are arranged in the shell, the gas pipeline and the combustor are arranged adjacently, through the structural design mode, gas can fully exchange heat with heat generated by the combustor in the flowing process of the gas pipeline, the temperature is increased, and the heat exchange efficiency is improved. It is ensured that fuel gas can be fully combusted after entering the combustor, the stability of fuel gas combustion is improved, a large amount of toxic pollution gas generated due to insufficient combustion is reduced, the use safety performance is improved, meanwhile, the energy utilization rate of fuel gas combustion is increased, and the phenomenon of pipeline frosting is not likely to happen. In addition, a supporting plate is further arranged in the shell, on one hand, the combustor can be supported and fixed through the supporti
