I am doing a pool refresh to fix some cracks at the waterline and it has me thinking about redoing the pump and filter... May as well just bite the bullet.
For a while, I was not able to run the pump and I noticed the robot did a decent job keeping the pool clean all by itself. I am trying to figure out what it would look like to run the most energy efficient pool set up.
I have a plaster pool, 20k Gallons. 2" pipes and a short distance to the pump and filter pad, call it 10 ft. Nothing fancy, one valve for surface, one for bottom suction, pump, filter, back to the pool (no spa), all on one discharge header. Clean, simple.
My thought is a 400 sqft cartridge filter to minimize head loss. Low power variable pump to do one cycle per day, running at about 25 GPM for 12 hours a day. I think that's like 150W with the Intelliflo at speed 1... Like $6/month. Run the robot at that time to stir up and clean the bottom, for something like $2/month...
Seems like the cost to operate the pump would approach negligible... Am I missing something obvious? Saving that much money per month, would pay back pretty quickly in Texas where I run about 8 months a year.
Why am I wrong here?
