I have an inground system currently with a whisperflo 1.5hp pump. DE filter, heater+Jandy Aqualink RS system
It has to drive a caretaker system, a fountain (four deck jets) and a SWG.
I was working the math and it seems like the energy savings might be worth it.
Instead of running the Caretaker and pump on full for 10 hours or so,
I was thinking
2 hours at 60GPM, essentially full speed for the Caretaker (only return is caretaker and fountains)
8 hours at 30GPM, min flow for the SWG - uses 1/4 energy as full speed - run fountains at this time (2pm-10pm) - some flow will pass through caretaker also.
14 hours at 15GPM for circulation - uses minimal energy.
If I do the math, this saves me about 1/2 on electric and should give better mixing, etc.
However, I am concerned about running the Caretaker too little and having to run 30GPM for the SWG to work requiring flow that minimizes any advantage from the VS pump.
Thoughts?
