variable or 2-speed pool pump
I put this on TFP, but hoping for more insight. Looks like the variable will be $550-$700 more. We have an older passive solar on our 1 story roof right near the pool. We pay up to .33 in summer and .23 in winter (ack) for PGE (we have a well pump too). I wouldn't mind going for it and buying a Pentair VF *IF* I thought if would last or had a 3 yr warentee at least. Such a gamble! Wish I knew the fail rate. Advice?
spec: 17K gal, IG, plaster, DE, flow rate 72, Hayward 1.5 HP, Booster 3/4 HP, Polaris, solar 1 story, 2 1/2" pipe, Santa Rosa CA
