Trying to do some research and some math but I’m getting confused and have some questions.
PB wants to put in a 1HP single speed pump. We will have 20k gal of water, a SWCG, a pool heater and 2” plumbing. (details in siggy line). Should I swap for a 1 HP 2 speed or 2 HP 2 speed pump? I’ve only ever had a single speed pump on previous pools.
So I assume that with a two speed pump to save money you would run the pump for example 12 hrs on low through the night and 12 hrs on high during the day (just an example as I know depending on temp, time of year, pollens, storms, bather load etc it changes). I would need to install a timer or something to switch between speeds?
What would automate speed change that is not a digital gadget? (Because cost, so many expenses when building a house)
Our PB recommends running the pool pump for 24 hrs a day because we have such hard limestone mineral rich water here in central Indiana that builds up and scales. Is this bologna? Wouldn’t proper pool chemistry combat this line of thinking?
Last but not least, math.
The 1HP pump is 8/16 amps and 230/115v
8x230=1840/1000=1.84 kWh
The 2 HP 2 speed is 10 amps and 230v. (Jandy Flo Pro 2hp 2 speed FHPM 2.0-2)
10x230=2300/1000=2.3 kWh
Average cost of electricity in Indiana as of Dec 2017 is 11.29 kWh.
Now how much would it cost to run the pump 24 hrs on low and 24 hrs on high for each pump?
Thank you for any help and any information!
