I've noticed I can get a Hayward 21" Sandfilter with 1.5HP Powerflo Matrix pump new for less than $200 right now.
Next season's plans are to upgrade, but I was planning to get a 1HP pump. I wanted to get a pump big enough to run 140 SQ FT or so of solar panels on top of a 1 story garage, but not break the bank to run 8+ hours a day when the panels are in the sun. I do plan to eventually upgrade the pool to a hard walled 21' or 24' round AGP, but realisticly not for another 2-3 seasons, or until the Intex fails.
I was trying to avoid a 2-speed or VS right now, I wanted to keep this simple and inexpensive.
How much more energy would the 1.5HP use over the 1HP? 1-1/2 times? 3 times? I barely notice the Intex 3/4HP on the utility bill.
Would the additional 0.5HP be really worth the added operational cost? I'm just starting to research pump curve, head, etc, is the 1.5HP pump's power over the 1HP really noticeable (or needed) when vacuuming, or running solar like I describe?
Thanks in advance!
