I am thinking about the idea of replacing my current single speed Pentair Whisperflo 1HP to a variable speed pump in order to cut down electricity bill, since the utility company has an $200 incentive for a VS pump. I currently have my eye on Hayward MaxFlo VS for its low price ($615 on Amazon) and popularity. But I don't know if it is a good choice for my pool, since from what I hear it is a medium head as opposed to my current pump. My pool is about 20000 gal. It has 2" pipe and the pump is about 25 feet away from the pool. I have a spa connected to the system but I have no intention of using it.
Is MaxFlo VS going to be a good fit for my pool, or are there any other recommendations that are worth the investment? Thank you very much for your advices in advance!
