Running the numbers for chlorine maintenance costs.
Would someone please check this? I'm making some generalizations...

23000 gallon pool
Jun-Sept : 2 ppm per day = 240 ppm
Oct-May : 1 ppm per day = 240 ppm
480 ppm per year

1 ppm (my pool) is .191820 pounds - (23000 * 8.34 / 1000000)
480 ppm = 92.0736 pounds Cl

10% Cl has .834 lbs/gal
480 ppm = 110.4 gallons

$4.49 / gal of HDX at my Home Depot -> $495 per year.

Initial purchase price for an SWCG is similar to 2-3 years of liquid chlorine for my pool.

Thnx,
Bill
Minor adjustment. 10% chlorine weighs approximately 9.8 lbs per gallon.

You can into your local area to see if any company that will "lease" you the product with no money down.

We charge a flat monthly fee based on the size of your pool, we install the SWG and replace the cell as long as you remain on the program.

No upfront cost at all, maybe even cheaper than buying chlorine.

I think I've convinced myself that the purchase price is worth it. I'm going to do some re-plumbing this winter and will probably add an SWG then.

That’s the perfect time to redo anything or everything. I redid mine from the filter on.

There are a few other factors for the equation like the incremental electricity for the SWG and bags of salt but they don't change the outcome that the ROI is better with the SWG.

There are *other* factors as well. For example, I ruined ZERO clothes in 8.5 seasons with SWG. I’m a big clumsy oaf, my entire wardrobe would be polka dots with liquid chlorine.

I think for something that provides so much convenience and peace of mind, any discussion of return on investment is a fools’ errand.

I came here to say this. A pool is a hole in the ground where we throw money, time, and effort. Of course it's important to control costs, that's why we came here instead of helping to keep the pool stores in business. Any minute of the day I spend on maintenance is a minute I can't spend enjoying the pool or something else in my life. That's the only currency that matters to me.

I already waste too much time obsessing about my pool's chemistry and coming here and mis-reading people's posts and typing long replies to questions nobody asked... So I'll answer this one:
Would someone please check this? I'm making some generalizations...

Generalizations are good and all, but I don't think it's cost that should be the determining factor for installing an SWG, not even the pool volume breakpoint calculation. There's no such thing as ROI on a hobby because the other nonmonetary benefits can't be generalized away or ignored. If you've got the money in the checking account to buy a SWG, it's my mathematical opinion that just like the rest of us YOU'LL FRIGGIN LOVE IT and wish you hadn't done the math because it doesn't matter. Oh wait, that's not math. Okay, Math: It's different for everyone because volume, sun exposure, latitude, everything is different, so do some measurements on your pool now while it's a seasonal change. You and I are at very similar latitudes and my latest test indicates around 0.4ppm FC lost because SWG created 0.9ppm for a net 0.5 increase. It's fair to assume we'll be swimming less and the sun will fall further behind the trees in the coming weeks, so my SWG use is dropping drastically. I prefer taking the conservation of mass approach: Take two FC measurements at the same time each day. FC(yesterday) - FC(today) = FC(gen) - FC(lost). There's any number of ways algebra can make that equation fit into my head, just depends on the day.

Very well said, like this what kind of car do you drive or want?? Well a 1976 Pinto will also get you to work and back. I can pick on Pintos because I had one. Had to back in because reverse didn’t work when it was cold

@trivetman We are a B&M small pool service company in NC (not a nation wide chain that you would know). The equipment lease (mainly SWG and VSP) started a few years back and we work with many small business (a lot of one or two man operation) in the nearby state. Lease is based on the pool size (gallons) per month, customer agree to a fixed fee + chemical cost. We (or the pool man) would service the route, replace the cell (if needed cleaning or dying). Customer pays nothing down, we supply the all the equipment (cell or the whole system) to the partner (they get an installation fee + monthly service fee). Usually we require customer sign a 3 year min lease (as we do not make any profit first 2 years). If customer have a working system (say aquarite) , installer are required to add our wifi module to it, so we know the performance daily. Each partner have a dashboard they can view all their customer, and suggest what needs to be serviced (priority). They are given advanced warning (like we know a cell is getting a lot of build up on the plates).wifi aquarite.png

@rj45 - Say I had some spare time and just don't get my fill of maintenance from my pool and want to hang out at other ppl's pool for beer money - have you considered partners in states farther away?

Honey wake up. Its 1am and some guy is outside taking your SWG apart..

@ccbill We are considering expanding our program to all lower 48 states, but it will take some time (maybe next year)
This is really for people in the business, as you need a min number of customer for us to be profitable starting in the third year.
We typically invite the potential partner to come for a one day presentation, so they are all within driving distance.
Again I do not know how many other ppl's pool you plan to take care of.
Setting up a web portal for you with only couple of "other people" is pool is not going to make financial sense.
There is a fixed cost associated with a back end database to give you the SWG.CCBILL.COM with live customer data and route planning.
And there could be customer that is in "RED" status and require you to service immediately or their pool can turn green.
Shipping you a large box of Chemical (most of them only come in one size) according to the system prediction and you may not be able to use up in a year.
All those could be potential problems.
Now if you know a local pool man (or company) that have hundreds of existing account they are already maintaining, we can certainly work with them when we expand.
We have presentation already, and we can do training over computer. Install is very easy.

Don't forget to include the cost of muriatic acid. Since I've switched to my SWG, I traded in my task of pouring chlorine for pouring in muriatic acid. Although I'm not having to pour quite as much muriatic acid as I did chlorine, nor as often.
