• Which size pipe should I use, DN12 or DN16?

    DN12 is recommended for a single solar thermal panel.

    DN16 is recommended for two or more solar thermal panels.

  • I am confused about the terms FLOW and RETURN pipes. Are they different?

    Yes.

    The flow pipe carries hot water from the solar thermal panel(s) to the cylinder. It is fitted with the temperature sensor cable which links to the digital controller.

    The return pipe is used elsewhere in the circuit and carries cold water.
