I currently have a 1.5 HP superpump driving my filter. When I opened this year, it seemed a bit noisy starting but it calmed down. The housing fairly hot to the touch though.
I calculated my monthly electricity cost at ~$200, which is about how much I see bill rise when I open my pool.
Question: I suspect the electricity savings would pay for a new pump in a year or 2, especially if I went to a 1 HP 2 speed pump running full speed only 4 h/day.
20,000 gal pool. I have a main drain and skimmer, 25' from the pump, plumbed with 1 1/2. 1.5 return line supplying two return jets and another 1.5 line supplying 2 jets in the steps.
The pump also goes through a sand filter, a NG heater, and a SWG.
The sand filter usually reads 13-15 PSI; I backwash when the filter goes over 17.
I tried a timer running about 40% of the time last year but I had some algae outbreaks.
So...
1. Can I go down to a 1 HP , 2 speed motor?
2. 4 hours/day enough?
3. Should I just buy a new 2-speed motor, or is the SUPER II much more efficient to make it worth while to replace the entire pump?
4. I've seen a neighbour with a 3/4 HP pump on a pool of similar size. Could this be appropriate?
5. I've also been thinking of a supply side robot like the MX6? Do I need more power to drive this?
Thanks, Tim
