Hello. I am a new member from TX. I bought a house that has a nice pool, but it consumes quite a bit of energy. There are 12 pumps on the system, but 4 of them consume the bulk of the energy each month. The rest are accessory pumps for water slides, waterfalls, etc. I spoke with a few local pool companies about variable speed pumps, but I was not impressed with their knowledge and pump selection process. None of them asked me how many gallons are in the pools, and none of them were able to provide payback calculations. Hence, I created a couple spreadsheets to work through the process myself. There are 3 cartridge filter pumps on the system, but the spa pump doesn't seem to run enough hours to warrant an upgrade to a VS pump. However, since this the first time I have owned a pool, I would like to get some advice on the pump selection process. Please review the attached spreadsheets and let me know if you have any suggestions. In summary, I am planning to replace the main pool filter pump and the catch pool filter pump. On the latter, it looks like there are too many turnovers with the current schedule, but I'm not sure if this pump was originally sized to also run the in-floor cleaning system. I would also like to cut down on the power consumption of the main pool's in-floor cleaning system, but I'm not sure how many GPH this system requires. It probably would be easier to simply run the in-floor cleaning system fewer hours per day.
I appreciate any help and/or insights into this process!
Thanks!
