But that ignores the initial cost. At $1000 initial cost to have the builder install it you're looking at an additional $100 per year for a 10 year period of ownership. Besides that, Carl's estimate was intentionally high to make his point ( I typically spend less than half that). Finally, Pat's supposition that power costs will drive bleach costs up in the long run applies more directly and at least equally to the power costs for operating the SWG.
Yes Kurt, I ignored the initial cost of the unit for a reason. That takes care of the intangibles, like going away on vacation, not having to worry too much on keeping the pH exactly between 7.2 and 7.6. It will look after itself a lot better than you think, and I am on my second SWCG, an upgrade from the first one, for that very reason. Yes I still use bleach and pucks on occasion, but overall it gives me peace of mind. I hope this answers you next statement below.
I want to believe that an SWG will pay for itself (as that would make my decision very easy) but it just ain't so.
(On the other hand, it really doesn't cost
that much more in the long run. I almost have myself talked into this; thanks Sean

.)
