[0002] With the continuous advancement of science and technology and consumers' constant pursuit of quality of life, gas water heaters, as an indispensable device in family life, are increasingly concerned about their performance and quality. In this context, the space occupancy rate of the water circuit device of the water heater and the noise generated internally during operation are increasingly attracting people's attention. In the existing water circuit device installation structure of the water heater, the water pump is mostly installed on the side wall, resulting in the need for a wider installation space.
