My motor went out on my pump two years ago during a real hot spell so I just went to the local pool store and replaced it with the same single speed motor even though I had been wanting to replace it with a two speed motor. I am now thinking of upgrading to a two speed motor to lower my electric costs and keeping the single speed as a back-up but don't know if I really would save enough to make it worth my time.
What I have:
20*40 Liner pool with spill over spa and electric cover
Pump is a Hayward SP2610X15 1.5 HP (Pump is 5' from pool with no hills)
RPM 3450 18.6/9.3 210 Volt
Jandy Purelink with PDA (Salt System with Automatic Jandy Valves)
Use a robotic pool cleaner
I am confused what I pay "Total" per Kilowatt so here is my bill says
Power Supply Energy 544 KWH @ 0.06726 $36.59
1181 KWH @ 0.08136 $96.09
Distribution 1725 KWH @ 0.04195 $72.36
Energy Optimization 1725 KWH @ 0.002538 $ 4.38
Questions I have:
1. Where can I get the best price for a two speed motor ?
2. My SPA jets don't have as much pressure as I would like so would a 2HP motor increase the pressure?
3. Can my Jandy be wired to change the speeds of the pump ? Go to high speed when the SPA is turned on vs walking to the pump and hitting a switch ?
4. I run my pump about 12 hours a day so how much could I save with two speed pump considering the energy cost ? (Live in Michigan so pool is open only 7 months a year)
I read a lot of the existing posts on this subject and am still very confused so any specific information you can give me would be helpful.
