The invention relates to a visual remote monitoring system for hot water of a solar air source heat pump. The visual remote monitoring system comprises a monitoring computer, a PLC (programmable logic controller), an RS (remote sensing) 485 communication line, a monitoring sensing system and a control performing system. The visual remote monitoring system has the advantages of combining the monitoring computer and the PLC, providing a good HMI (human-machine interface) and a remote monitoring function for the system by using the monitoring computer, and enabling the operation to be more convenient and visual; the PLC is used, so that the automation degree and control precision, functionality, anti-interference performance and reliability of the whole system are stronger. The human-machine interface and the remote monitoring function are combined, so that a good using effect is achieved in the control system.
