I have a quick question on Variable vs 2-speed. I currently have a whisperflow pump WFE-6(with a rather oversized 1.5/1.47 SF = 2.2HP motor on it for my pool) and am looking to either jump into a Variable or 2-speed replacement (modestly sized for my smaller pool).
I have two motors I am looking at:
2-speed 1HP/1.65SF = 1.65HP A.O. Smith Pool Motor Square Flange 1 HP Full Rate Dual Speed w/ Digital Controller (B2982T) - INYOPools.com
$340
Variable speed 1HP/1.65SF = 1.65HP A.O. Smith 1.65 HP Variable Speed Pool Pump Motor Square Flange - ECM16SQU - INYOPools.com
$399
Both are AO Smith Motors, both same specs HP wise, They will be placed into a pump that is obviously made for a larger motor (so no problems with impeller replacement to size up).
I have always been under the impression that Variable speed is significantly more expensive, yet not so much the case here. Am I missing something? I know that appropriate surge protection is needed for variable morethan 2speed/singles, but everywhere I am reading thus-far states that Variable pumps take significantly longer to make-up the cost of them.
My Power here in phoenix is a rather odd .06/kW from 1900-1200 and .24/kW from 1200-1900 so having the ability to really slow down the pump to 1-200 watts during peak time will save a ton. As it stands right now I simply run the pump on offpeak power time.
Any & all thoughts are appreciated. Seems strange to "only" see a roughly $60 in price diff from 2-speed to variable.
