I've read a lot of threads and looked a bunch of tables... just confused. Trying to figure out flow rate on low speed (Whisperflo, AO Smith 1Hp 2 speed, 3450/1725), 48 sq. ft. Pentair DE filter (20psi/4psi), 2" pipes, 30-40' to pool, 1' above pool. Buying a 110BTU heat pump rated at 25-80gpm, optimal 50gpm. I know higher flow is better, but if my Low is 40 gpm or so, I'd rather run on low 12 hrs per day.
Also getting a 3gpd variable Stenner pump (pool takes 25-40 oz. chlorine per day), plan on injecting slowly over 6-8 hr day. Be nice to run everything on low from 8 AM to 8 PM. Will need to upgrade timer if heat pump won't work on low. Sorting out what I need to buy.
