I don't know what temp it gets naturally, but keeping it cooler is probably going to be more difficult than warming it.some further questions: What temp does your pool naturally get? What temp do you want it? How big is your pool? If you didn't have the swamp cooler, how much would you need to run your AC?
I agree with the aforementioned mixer suggestions.
In addition, I'd recommend swimming if possible! Also, many of the robotic vacuum systems do a good job of pumping water vertically while having the obvious side benefit of cleaning the pool.
I don't know what temp it gets naturally, but keeping it cooler is probably going to be more difficult than warming it. I live in the desert--and literally listed as one of the hottest places on the planet.
If I didn't have the swamp cooler, I'd be running my A/C at least 10 months of the year. That said, I'm working with an engineer to switch over to geothermal, which is what made this device interesting. Otherwise, running the A/C is cost prohibitive even at .12/kwh.
I'm mainly interested in heating the spa. It's about 600 gallons. The pool is around 22K.
Yeah it sounds great.
So July Tampa weather of highs in the 90's and lows in the mid 70's and pool is only 74 on average? Ok
Then 2.5ton ac = 30,000btu an hour times 6 hours nets 180,000 btus. That's enough to heat a 4,300 gallon pool 5 degrees.
Those numbers are a bit suspect. We've got another member in Tampa who is actively working to cool their pool because it is close to 100 degrees. Whichnis also questionable and they probably need a new thermometer. My brother's. pool near Destin has afternoon shade and is in the upper 80s all by itself.
But, with highs in the low 90s and lows in the low 70s pool water will naturally seek the midpoint between high and low temps so it would be expected that the pool water would be in the low 80s without any solar heat gain from the sun. If the sun shines on the pool then it should be mid-80s or warmer.
How much do you run your AC in January? What temperate is it by you in January?
Yes, that is correct. The front of my house faces east, the back faces west and the pool is in the back, which means I don't get sun on the pool until the day is half over. Not only that but it is screened in with super screen. The hottest the pool ever got before we got this heater was generally in August and topped out at 78.
The pool is ~10,000 gallons with a pebble tech shell. I think 14' x 28' but I'd have to look at the schematics again.

Suspect huh? You do realize there are multiple variables in the heating of someones pool? I have neighbors that have pools 10+ degrees warmer than mine. They also aren't screened in like mine is AND their pool gets sun ALL day, mine does not.

I run my A/C here in Tampa almost 365 days a year. These last few years its been warmer and warmer in the winter. I think last year in January it was almost 85 ever day.
This thread is a treasure trove of info! Loving it.
I can see that there's a bit of controversy regarding the true nature of this "free" energy as captain points out. I'm in south florida and installing this would likely mean my pool heater would run more than the 6-8 hours I like to run it per day.
Has anyone wired it with a timer, so that you can set a particular hour range in which the FPH is allowed to operate?
For example, I'd like to limit the FPH such that it only operates between 11pm and 11am. I run my pool pump 6 hours between 12am and 6am since my electricity is cheaper at night.
Our AC runs for about 4 hours between 11pm and 11am in months april-october.
In months november-march, my TOU rates shift and electricity becomes cheaper between 10am and 6pm, so I'd run the FPH then and get about 3hrs of AC usage per day.
So I guess my question is two-fold.
1. Is this possible?
2. If possible, is it worth spending ≈5k to get an average of 4hrs of pool heating per day? My pool is 40k gallons.
@OneLoveAmaru could you provide your installer in the Tampa Bay area? Same issue many A/C folks are not familiar about the product. I already have the equipment from HotSpot, now seeking someone to perform the connections. I can send you my contact information, if your installer is interested I'm in Brandon/Riverview area. Thanks!
I purchased the Fph in April 2017. Long story short, I have spent thousands and in September had to replace my condenser. Hotspot says it's because my installers installed the valve wrong. They are not willing to help me recoup any of my expenses.
