    I am in the process of buying kit for a solar system installation and am now looking at the pump station, I see there are single line and twin line...Can anyone tell me what is it that the two do different or why would you have a twin line as oppose to a single line?

    Cheers

    The twin line one usually incorporates an air vent for extracting air from the system. This is useful for DIY but not necessary if you have a filling trolly to filling and removing air from the system. It also includes a second non-return valve (on the flow side), and depending on your circuit, this may help to prevent heat rising in the pipe at times when the pump is off.

    Many professional installers also prefer the twin line because they use flexible pipework from the panel to the cylinder and this can be more easily cut and connected to the pump station, which may then connected on to the cylinder in rigid copper.
