Thanks. Best I can see @ the 1/2 HP level is this: Pentair uses 10% more power than the Hayward, but will push more water (for my 25 GPM design point, we are talking 50 ft dynamic head vs 35 ft) and costs, best price I can find, 70 bucks more. The Hayward worked just fine, as I noted earlier, so I don't see much point in a higher purchase price with a higher electric bill, for the same number of runtime hours - note that my runtime hours are really tied to the solar heat, rather than filtration... Sooo, a new Hayward looks like the right answer for me.
