I've been reading about the energy efficient pumps now available. I'm thinking about replacing my current pump with one of these for the energy savings as well as the noise reduction. My current pump is a 2 HP Pentair Challenger high head high flow pump. The noise from it has always bothered me, especially when we have guests over. I typically turn it off then so conversations are easier.
The pump and my pool are almost 8 years old. My pool is 15' x 30' and holds about 16,000 gallons. It has 4 return lines and 2 floor drains as well as the skimmer. I'm using a Pentair cartridge filter system. The pump is connected to 1.5" PVC piping. I use a robot for cleaning my pool instead of vacuuming with the pool pump. My energy cost here in Texas is about 10 cents/kWh.
I'm looking at three Pentair pumps; 011018 Intelliflo VS ($863), 011012 Intelliflo VF ($1,200), and the 022005 Intelliflo XF ($1,120).
Which pump would you recommend for my set-up and why?
What benefit do I get for the additional $250 - $350 if I get the 022005 or 011012 instead of the 011018?
Will I be able to install any of these pumps as a direct replacement? I.E. do I need anything else to control any of these pumps? As far as I can tell, I can just unwire and disconnect my current pump and use the same wiring and piping for the new pump.
