In the controller 70, the total time length used by each wall-hanging stove 11 and the fault condition are recorded, and options at each start are adjusted according to the records to ensure that the service time of each wall-hanging stove 11 is basically equal, and meanwhile, the fault products are removed so as not to be started.

In the embodiment shown in fig. 4 to 6, the gas heating and water supply system 100 includes a heat source body 10, a water supply device 20, a heat supply device 30, a heat exchanger 42, a water storage container 50, a second water inlet pipe 60, and a controller 70.

When heating is needed, the central control part judges whether heating is needed or not, estimates the total heat load needed, determines the number of the wall-hanging furnaces 11 needing to be opened according to the estimated total heat load, and opens the wall-hanging furnaces 11 to perform heating circulation. At this time, the opened circulation pump inside the wall-hanging stove 11 drives water flow to continuously circulate and heat in the heating circulation, and then the water of the heating device 30 is exchanged with the heat through the heat exchanger 42, so as to promote the water of the heating device 30. While the wall-hanging stove 11 is heating, the controller 70 will also continuously adjust the number of the wall-hanging stoves 11 that are turned on, the heat load of each wall-hanging stove 11 and the outlet water temperature according to the change of the water flow and the temperature change, so as to ensure the outlet water temperature to be constant.

When hot water is needed, the central control part judges whether hot water heating is needed or not, estimates the total heat load needed, determines the number of the wall-hanging furnaces 11 needing to be started according to the estimated total heat load, and starts the wall-hanging furnaces 11 to perform hot water heating circulation.

The water supply circulation pump 13 circulates the heated hot water to the water storage tank 50, and at the same time, brings the cold water in the water storage tank 50 back to the wall-hanging stove 11 to be heated. When the temperature of the water in the water storage container 50 reaches a certain temperature, the water pump 23 is started to operate, so as to bring the hot water to each water supply part 201, thereby ensuring that the hot water is instantly boiled. When the water supply part 201 is used, the second water inlet pipe 60 connected to the water storage container 50 will synchronously add water into the water storage container 50, so as to ensure that the water level in the water storage container 50 is constant. While the wall-hanging stove 11 is heating, the controller 70 will also continuously adjust the number of the wall-hanging stoves 11 that are turned on, the heat load of each wall-hanging stove 11 and the outlet water temperature according to the change of the water flow and the temperature change, so as to ensure the outlet water temperature to be constant.
