Q- How will I know how much restriction to place on the return line? Maybe a 1/4 turn?
Steve, the CL is for flow. At 1ft of headloss my return pump is rated at 700gph and my circulation pump is rated 1,100gph.  |
The problem is you don't know how much flow your chiller will be getting, and actuallly it will probably be inconsistent given ball valve's tendency to collect and release crud inside them when operated in partially closed positions.
I honestely think the best bet is to get a small submersible pump to feed these things. But what you have drawn up will work.
