Detailed Description

In order to better understand the purpose, structure and function of the present invention, a strong pumping type gas water heater of the present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the strong pumping gas water heater of the utility model comprises a shell 1. A gas channel and a hot water channel are arranged in the shell 1. The gas channel is used for allowing gas to enter and combust to generate high-temperature flue gas; the hot water channel is used for feeding cold water, and heat exchange is carried out between the hot water channel and the gas channel, so that the cold water is heated, and hot water is discharged.

Specifically, the gas channel includes a burner 2, the burner 2 is provided with a gas inlet 11 extending from the bottom of the housing 1, and the gas entering from the gas inlet 11 is combusted in the burner 2 to generate heat.
