I currently have a 1 hp single speed filter pump and a 3/4 hp booster pump to run our Polaris cleaner. Both pumps use about 1.1 kW. I live in CA, and the electricity rates are pretty high -- up to $0.33/kW -- so I am considering replacing these pumps with more energy efficient pump(s).
Is there a way that I can replace the two pumps with a single, variable speed pump?
The suction for the booster currently comes off the return line for the filter pump. Any thoughts or ideas would be appreciated.
