I recently bought a St Louis 1972 home with a diving pool. I am step by step working on the house and the pool is one of the major projects. But heavy work is down the list as its functional now. So looking for power savings, noise reduction, and auto chlorination for now. Original to the house, it has no spa or any water features:
- 28-30,000 gal open "L" pool 8 ft dive end 4ft shallow with original plaster
- AO Smith B855 motor pump that runs 24/7
- Single 2" return and 1.5" discharge line to pool (line from ground is 2" both ways but the lines from Filter to Heater, and heater to ground return are 1.5")
- 2 skimmers and bottom drain (I assume they all pipe together back the single return at pump)
- Raypak 2100 heater - Faulty LCD (otherwise functional)
- Pentair NSP72 - Diatomaceous Earth Filter
- Pressure on filter reads ~25psi (not sure if they back washed yesterday so I will check again after a backwash)
I plan to replace the motor with a B2983 per B855 Motor Discussion
Add timer Intermatic 1353ME with case 2T2502GA
Add Hayward CL220 offline chlorine feeder
Eventually replace board on heater (works fine, just can not read display) We use rarely so not in a hurry to spend the $300ish to fix
At $.08 kWh I am spending just under a $1K currently running for 7 months of the year.
Between the timer and 2 speed pump I calculated a saving of ~$600 a year compered to the status quo assuming a run time of 12 hours each day
It needs coping replacement, deck work (concrete), and a new resurface. But the pump should pay for itself in a year with a timer and new motor " I think". Can anyone check my thought processand let me know if my plan is right? (pups, run times, etc)
Thanks for any help!
