I have a pool in France, 80m3 (20000 USG), SWG, glass media filter, 1HP fixed speed pump that draws 4.5A @ 230V & runs for 12 hrs a day during the summer, costing about $1.50 per day, $270 per season on cheap rate electricity. Pool cleaner is electric.
Am considering changing to a more efficient pump such as Pentair Intelliflow but not sure that I need variable speed since I don't vacuum clean. However, I do need to backwash every few weeks.
Is the Intelliflow a cost effective choice for me or would you recommend something else?
Thanks for any advice,
