Choosing the right SWCG

[CarolD]

I've been doing research on which SWCG to buy to convert my pool from liquid chlorine. I have all Hayward equipment and automation right now. I've read where I should size the SWCG at twice the size of my pool, so minimum 42,500 gallons. I saw a previous post where someone suggested going even higher (a 60,000 gallon unit for a 25,000 gallon pool) to increase the lifespan of the unit.

Am I correct in thinking that purchasing a Hayward SWCG would enable the best use of my existing automation? Is there interoperability between SWCG and automation manufactured by different vendors? And if Hayward is the best choice, it appears that the largest unit they make is 40,000. Is that large enough for my 21,250 (including spa) pool?

Thanks so much for any help you can provide!

Carol,

With automation, it is almost always best to go with the same brand of SWCG.. A 40K SWCG in a 21K pool will work just fine.

Thanks,

Jim R.

Thanks, @Jimrahbe for your response! For my own education, assuming I had a much larger pool (say 45,000 gallons) and Hayward automation, what would I do then for the SWCG, since the 40,000 Acqurite looks to be Hayward's largest unit?
