Good morning Jim,
THX for the feedback... this pool thing is new to me... lots to learn!
I may need to modify my sig line slightly... I was told by the seller the pool is 40K gal... after measuring it repeatedly and doing the math... it comers out closer to 35K (including the SPA). Also... the solar arrangement is on a 2 story high roof... I am estimating the lift up 2" PVC and to the top of the slope of the roof is close to 30 ft. Finally... the pool is not really indoors... rather it is a metal/fiberglass enclosure over it... need to figure out how to post a cell phone pic... it is an ingenious custom built arrangement, with 6x 8ft square skylites that open!
The reason I posted all this information... is when I tried to calculate the TDH (head) and GPM...
I am getting a head of 70 and GPM in the 65 range...
Now if I remove the ~30 extra ft of head for not running the solar... I have a head back in the ~40 range... which seems more realistic.
I was looking at pump charts... and this is pushing the edge of performance data...
It would appear that running the VS pump with the solar engaged... would require to run the pump close to 3000 RPM's...
I am kinda hesitant to buy a $1000+ pump, designed to run at partial RPM's, and load it down to 80-90%+ of its rated operating ability... especially when the manufacturer is not gonna give me any warranty (DIY)...
Do you have any suggestions as to where to go with this...
Maybe use a VS pump for the pool and a booster pump for the solar?
THX for your input...
Perhaps I should start a new thread for this... it may get involved.
THX again... learning...
