Abstract: The system mainly use wall-mounted gas boiler and give priority in use of solar energy in order to maximize the utilization of solar resources. The excess heat will be added to domestic water when the heat for floor radiant heating is enough. The PLC of Siemens is set as slave computer in the monitoring system and it is used to collect thermal parameters such as temperature, flow rate, etc. by temperature sensors, pressure sensors and flow rate sensors. WinCC is set as the host computer to monitor the operating conditions of the entire system. Real-time tracing, monitoring and alarming function can be achieved based on the SQL database, which has realized archive management of the date. The system has been debugged after the whole experiment platform is completed, and the running state of the system shows that this system has high reliability and good stability
