I am looking for a new pump/filter for our pool. I keep reading about the energy savings of a 2 speed versus 1 speed. Aren't all pumps measured the same as far as volume of water they pump though? Am I missing something as I feel like I could run a 2 speed on low a lot, or a 1 speed on high with a timer for far less time. Wouldn't it work out to be similar in electric cost if they both filter about the same amount of water?
looking at either:
Hayward CC15093S Xstream Full-Flo 150-Square-Foot 1.5 Horsepower Filtration Filter
Hayward CC150932S 150 Square Feet XStream Above Ground Full-Flow Cartridge Filter System with 2 Speed Power-Flo Matrix Pump
thanks for any help!
