I would be careful upsizing an SWG. The recent crop of them have had shorter than expected lifetimes and so the ROI isn’t as good. Sure, they have higher output and so you run them less which theoretically translates into a better ROI …. IF, and it’s a big IF, the unit ACTUALLY lasts for 10,000 hours. There are definitely failure modes that can kill the SWGs much sooner than that and usually just outside the 2-3 year warranty period which then completely tanks the ROI.
I would say that 2X the volume is a ceiling more than a floor and would rather pay less up front in the chance that you get a shorter than expected lifetime. If you take the plunge on the larger unit, you’re buying a whole lot of “theoretical chlorine” that may never materialize into “actual chlorine” ….
In short, an IC40 is fine … my first cell was an IC40 and it went the distance and lasted almost 8 years. My replacement IC60 is dying and only lasted 3 years.
Good insight. Thanks for the info!
