I have been looking in the pump forum and also all over the internet. And I am still not sure which pump to buy.
Our priorities and specs:
-#1: low monthly elec. bills - would like 2-3 yrs return on investment if we buy more expensive pump.
-a very distant second: quietness
-1 skimmer, 1 main drain, and they are both close to the pump house, about 20 ft, nothing goes around the pool.
-no spa, heater, etc. may get solar heater in the future, but no plans for now.
-probably only going to use pump for filtration, circulation - we will clean manually.
-electric rate is very high - .25-.35/kwh
Can we get a away with a very small 1 speed to meet our needs, will amps/watts be lower with a 2 speed on low, or is the only way to get the lowest amp/ water drawn to get a variable speed, and is that worth it compared to a 2 speed on lower setting?
I am having a hard time finding numbers to compare, and I know that that is partially because the efficiency depends on the water drawn.
Thanks for any specific help you can give.
