Hello
I have to replace or repair my current pump so I am trying to calculate the potential savings of a variable speed pump.
My current pump, I believe, is 1.5 HP and I think it came together with the DE Filter (Hayward DE Filter DE2420 1.5hp) My pvc piping is 1.5 inch. I usually run the pump about 11 hours per day most of the year as I am in Tampa. I think this means my maximum flow rate will be about 42 gpm? Power is about .10 per kw. Another site I used calculated 1.5 hp to use 2.14 kWh and 1HP to use 1.72 kWh.
I was looking at the Hayward SP2303VSP MaxFlo VS Variable-Speed Pool Pump which is 1.65 hp and I am guessing I would run this at 1HP since my flow rate is limited? I am open to all VS pump suggestions. Below is what I have calculated but I am not sure what I might be missing.
Also had a few questions:
Using the calculator for another pump, the Tristar VS 900 https://www.hayward-pool.com/shop/en/pools/EnergyCalculatorThe savings seem huge and it seems like I would be running the pump up to 19 hours a day. Do most VS pumps run that long?
Should my goal be one turnover per day? I have a swg if that is a factor
Also, should I be looking at any other factors/variables since this may be an expensive purchase. I see low rpm settings with longer hours but I am not sure how to calculate the cost and run times.
Thanks for the feedback, I currently spend about 500-600 a year on electricity for my current pool setup.
