The choice of the diameter of the hydraulic lines between the DualSun panels and the technical room directly influences the hydraulic pressure drops.
We have defined charts for the different possible applications with DualSun Spring panels: flow rates per application are recommended to optimize heat exchange.
1 - Individual Solar Water Heating Application (ISWH)
The nominal flow rate is 32 L / h / panel, and we recommend to install multilayer pipes for their ease of implementation.
2 - Individual Solar Water Heateing Application (ISWH) with Thermal Discharge
The nominal flow rate is 100 L / h / panel, and we recommend to install multilayer pipes for their ease of implementation.
3 - Direct solar pool heating application (without heat exchanger)
The nominal flow rate is 200 L / h / panel and the pipes must be PVC pressure.
