[0021] In this embodiment, if Figure 1As shown, a monitoring device for a hot water system includes a control module 9, the output end of the control module 9 is electrically connected to the air source heat pump 1 and the gas water heater 6, and the input end of the control module 9 is electrically connected to the terminal. Further, the terminal includes a mobile phone terminal and a computer terminal, and the mobile phone terminal and the computer terminal are both electrically connected to the input end of the control module 9. The air source heat pump 1 and the gas water heater are both connected to the hot water tank 2 through corresponding pipelines. The hot water tank 2 is provided with a water supply pipe 4. Preferably, the water supply pipe 4 is provided with a solenoid valve c3, and the solenoid valve c3 is electrically connected to the control module 9. A plurality of liquid level sensors and temperature sensors 5 are provided in the hot water tank 2, and the liquid level sensors and the temperature sensors 5 are both electrically connected to the control module 9. The hot water tank 2 is provided with a water pipe 12, which is connected to the water inlet end of the water-using equipment, and the water outlet end of the water-using equipment is connected to the hot water tank 2 through a return pipe 7. First, the temperature change in the hot water tank 2 is detected in real time by the temperature sensor 5. When the temperature is lower than the set temperature, the terminal sends an instruction to the control module 9. The control module 9 controls at least one of the air source heat pump 1 or the gas water heater 6 to start, heat the water in the hot water tank 2, and stop heating when the set temperature is reached, so as to facilitate the use of hot water by the water-using equipment, replace the personnel to go to the equipment point to observe one by one for manual control, so that the hot water system can run automatically and improve the user experience; secondly, the liquid level change in the hot water tank 2 is detected in real time by the liquid level sensor. When the liquid level is lower than the set liquid level, the terminal sends an instruction to the control module 9. The control module 9 controls the solenoid valve c3 to open, and the water supply pipe 4 is connected to the municipal water supply, and then water is added to the hot water tank 2 through the water supply pipe 4 to avoid water shortage. In this embodiment, the liquid level sensor and the temperature sensor 5 are both existing products, and they have not been improved, so they will not be described in detail.

[0022] Furthermore, the water inlet of the air source heat pump 1 is connected to the hot water tank 2 through the water inlet pipe a10, and the water inlet pipe a10 is provided with a solenoid valve a, and the solenoid valve a is electrically connected to the control module 9, and the water outlet of the air source heat pump 1 is connected to the hot water tank 2 through the water outlet pipe a11. Further, the water inlet of the gas water heater 6 is connected to the hot water tank 2 through the water inlet pipe b13, and the solenoid valve b is provided on the water inlet pipe b13, and the solenoid valve b is electrically connected to the control module 9, and the water outlet of the gas water heater 6 is connected to the hot water tank 2 through the water outlet pipe b14. Specifically, when the temperature is lower than the set temperature, the mobile phone or computer sends an instruction to the control module 9, and the control module 9 controls the air source heat pump 1 to start and opens the solenoid valve a. The water in the hot water tank 2 enters the air source heat pump 1 through the water inlet pipe a10, and is heated by the air source heat pump 1 and then flows back to the hot water tank 2 through the water outlet pipe a11. This cycle heats the water in the hot water tank 2. When the temperature reaches the set temperature, the control module 9 controls the solenoid valve a to close, and the air source heat pump 1 enters the standby state. If the water temperature in the hot water tank 2 still does not reach the set temperature after the air source heat pump 1 is started, the control module 9 controls the gas water heater 6 to start and opens the solenoid valve b at the same time. The water in the hot water tank 2 enters the gas water heater 6 through the water inlet pipe b13, and is heated by the gas water heater 6 and then flows back to the hot water tank 2 through the water outlet pipe b14, thereby performing auxiliary heating to make the temperature reach the set temperature. When the temperature reaches the set temperature, the control module 9 controls the solenoid valve a and the solenoid valve b to close, and the air source heat pump 1 and the gas water heater 6 enter the standby state. In this embodiment, there are two air source heat pumps 1 .

[0023] In this embodiment, the liquid level sensors are distributed in the upper and lower parts of the hot water tank 2. Specifically, the liquid level sensor located at the lower part of the hot water tank 2 is used to detect the lowest liquid level, and the liquid level sensor located at the upper part of the hot water tank 2 is used to detect the highest liquid level. When the liquid level is lower than the lowest liquid level, the mobile phone or computer sends a command to the control module 9, and the control module 9 controls the solenoid valve c3 to open. Since the water supply pipe 4 is connected to the municipal water supply, water is added to the hot water tank 2 through the water supply pipe 4. When the liquid level in the hot water tank 2 reaches the highest liquid level, the control module 9 controls the solenoid valve c3 to close and stop the water supply.
