Pool water cooling

[mshumack]

When I built my pool two years ago (in central Florida) I added a heat pump to warm the water in the winter months. I have since discovered the real need is to COOL the water. My water is too hot far more often than it is too cold. From July through Sept the water temp is over 92 degrees). I like it around 85 dgrees.

I need a way to cool the water (about 10 degrees would be enough). Should I repalce the heat pump with a model that heats and cools the water? If so which brand?
Should I add an addtional cooler (for example the Glacier Pool Cooler GPC-25) which claims to cool water without freon saving electricity (its a non-heat pump device) or something else?

My pool is about 20K gallons in-ground, concrete pool, without a screen cover. I also have two waterfalls - but they add little to no noticible cooling effect.

Thanks

A fountain will work better than a water fall as it will allow more evaporation--but your pH will rise as a result.

What I do is run my solar panels at night, so they act as radiators. Unless it's like, 95, all night....

I didn't go with the solar panels because I had just replaced the roof th eyear before the pool install and my installer said that mounting panels on the roof would void the warranty (at least if the holes leaked) and some people were telling me I would/should have to remove the panels for every hurricane warning. The final reason was that that the heat pump cost $2700 and the solar panels were going to run around $6000.

Now, I just wish I'd bough the heat pump with the cool option.

Has anyone used/seen this Glacier Pool Cooler device? I can image just a fan blowing on coils or radiator would be enough to lower the water temp much.

Thanks.

A fan blowing on coils won't do anything unless the air temp is below the water temp. I suspect in Florida that is rare. How deep is the water table? I'm thinking if ground water is relatively shallow you have two choices. Use that water to cool the pool water by either burying pipe in the ground and pumping pool water through it or getting a water-to-water heat exchanger and pumping ground water through it. Ground water should be significantly cooler than the air or pool water. Usually 55 degrees as a rough number if I remember right. The flow rate for the ground water through the exchanger wouldn't have to be much at all. A couple ideas to ponder.

I own an Aquacal reverse cycle heat pump and am very please with it's performance. I am also in Florida. However, I use it only to heat since I like my water warm. I keep it at 88. The main reason I have the reverse cycle is that it will work in freezing temps and I also use it to heat my spa in the one to two months that it is too cold to swim.

Glad someone else asked this. I thought it would be something I'd get laughed off the forum for asking so I didn't, however I've been wondering about the same thing. The jacuzzi feels great hot, but 90 plus degrees in the pool is a little warmer than I'd like. It's not the end of the world but 80 or so would be so much better.

I must say I'm really surprised at how quickly water temp swings on sunny/rainy days. We had a few gloomy days last week and the water temp went from 90 to about 72. I thought it would take longer than 2 days to cool 12k gallons of water "naturally".

The pittance this forum cost for registration is probably going to turn out to be the best money I'll spend on the pool from what I can tell so far.
