The performance of a geothermal irrigation preheating system can be monitored and optimized through the use of sensors, data loggers, and control systems. Temperature, flow rate, and pressure sensors can provide real-time data on the system’s operation, while data loggers can track performance over time. Control systems can adjust the system’s operation based on changing conditions, such as irrigation water temperature and flow rate. Regular maintenance and performance monitoring are essential to ensure optimal system operation and identify opportunities for improvement.
