So is this 1/4 HP reduction = 1/8th (13%) electrical consumption reduction rule true?
I am looking at the Hayward EC50 with the 1 HP Matix filter system for an 18x33 54" deep AGP. I know this filter is oversized for this pool (good, right?) but I think the 1 HP is oversized too. I want to keep electrical consumption to a minimum even though our rates are $.085 per kilowatt.
I was leaning towards the hayward 2-speed 1HP so I could run in low mode. Will this save money?
Or should I just drop to a 3/4 HP on this filter and skip the 2-speed?
Other motor recommendations are appreciated. If there is a reasonably priced, high efficiency model that everyone likes, let me know.
Would upsizing to the EC65 be worth it for the larger filter area and flow rates?
