I am setting up to plumb my heat-pump loop and would like to build-in a spot for a future solar/alternative inlet and outlet. From looking at other designs, it appears that the solar outlet returns to the line before entering the heat-pump inlet to increase the water temperature prior to going into the heat-pump. Question, if I want to setup up just to run the solar loop, do I need a bypass around the heat-pump? Or, do I just run one solar outlet and allow it to run through the heat-pump plumbing even when the pump is off?
Thank you.
Thank you.
