In the use process, the gas heating device ignites and burns gas, and the smoke generated by burning has high temperature.
Specifically, the gas heating device may include a burner and a heat exchanger (not shown in the figure), the burner may ignite and burn gas, flue gas formed by combustion enters the heat exchanger, a first heat exchange coil is arranged outside the heat exchanger, and the first heat exchange coil is communicated with cold water pipelines such as a tap water pipe. The cold water in the first heat exchange coil absorbs the heat of the smoke in the heat exchanger and then becomes hot water. The heat in the gas heating device cannot be completely absorbed by the water in the first heat exchange coil, and if the heat which is not absorbed is further transferred to the shell of the gas water heater 10, the risk of scalding exists. In particular the panel housing 11 of the gas water heater 10, the user needs to manipulate the gas water heater 10 by touching the panel housing 11. If the temperature of the panel housing 11 is too high, there is a greater risk of scalding.
Based on this, in one embodiment, as shown in fig. 1, the gas water heater 10 includes a panel housing 11, an insulated water tank 13, and the gas heating device. The panel shell 11 with the relative interval setting of gas heating device, thermal-insulated water tank 13 is located panel shell 11 with between the gas heating device.

The flue gas in the heat exchanger of the gas water heater 10 enters the flue gas heat exchange channel 1411 from the inlet of the flue gas heat exchange channel 1411. The second heat exchange coil 142 is disposed in the flue gas heat exchange channel 1411, and a channel in the second heat exchange coil 142 is the heat exchange channel 1421. The flue gas entering the flue gas heat exchange channel 1411 exchanges heat with the water in the second heat exchange coil 142, and then heats the water in the second heat exchange coil 142.
Further, the water outlet of the second heat exchanging coil 142 may be communicated with the water inlet of the first heat exchanging coil outside the heat exchanger.
