Water Temp

[VOLDADDY]

I received the pool cooling devices today. I will try to install them tonight and see what they do. I will let you know. BTW-if you buy 2, the S&H is free.

People talking about heat pumps to cool the water got me thinking about heat pumps, and then about geothermal sources, and then about the possibilty of using a ground loop much like a GT heat pump would use to either lose, or gain heat. The kind I'm thinking of would be a well-type that would hold a U tube segment of the filtration system. No heat pump, just circulate the water into the ground where it's always 50-55 degrees. The technology's already proven. It would just need to be adapted to run pool water thru instead of coolant which would be trivial and well drillers are a dime a dozen.

We're just now rejoicing that the water temp has finally hit 80 so this isn't anything I need, just thinking out loud.

I will be interested to see if they work.

Keep us informed.

I had to go buy one of the keys to remove the pipe at the returns. I will do this tomorrow. It has been in the high 90's with heat indexes of 105+. We had a few days that weren't sweltering heat, along with some rain, and my pool came down to a refreshing 84. Now I'm sure it will be back to 90+. I will post back and let you know if this works or not.

Well, I installed the pool coolers tonight, and I must say so far so good. My water was 91 degrees tonight, and we have nothing but 95 degree days with heat indexes of 100+ ahead. As soon as I installed them and turned my pump back on, I jumped in to see what it would do. It was amazing. The water coming out of the device was about 10 degrees cooler than the pool water. You can stick your hand in the water, then immediately put it in the water being sprayed, and it is day and night difference. I left them in and running tonight and put my Aquabot in. I also had to shock as I have some algae developing. So there is a lot of stuff going on in my pool right now. I will post back and let you know the results, hopefully getting to below 85.

I am busy trying to lower the temp on my pool, since it hit 98 yesterday!

Hey CarlD, I'm assuming you mean the air temperature and not the water temperature. If that's the case, I'll trade. We've been hitting 100+ for weeks now. But, we may be a little more used to it. Our pool water hit 94 and running the fountain at night (temps in the low 80s at night) has keep the pool at 90 which is doable, but not preferred. How about a 500 lb block of ice that we could swim with, wouldn't that be fun.

Nope. Last night the air was about 85 deg, 99% humidity. The pool water was 98 deg, and, of course, 100% humidity!

This morning it was down to 92/93. Yeah, the water is THAT warm!

I'm running the solar panels at night and turning them off during the day.

shippy1973 I bought a second set of trippers for my intermatic timer and I run the pump twice a day. My theory is to let the extremely hot water on the surface sit there in the evening for as long as possible before I run the pump. The very hot water surface will radiate heat much faster than the cooler surface after I run the pump so I get more heat loss. On the other hand I have to mix in the bleach so I have the pump kick on at 8 or 9 and run for a few hours. One side benefit is that I find myself swimming around in the pool instead of watching TV and drinking beer..

I also liked the fan idea, it's usually very still around here in the evenings. I'll have to look into that. I've got a second timer, I suppose I could put some kind of outdoor blower on it. Has anybody tried this?

Well, I put the coolers on my pool Thursday night and had 91 degree water. Yesterday, it came a strong storm. Today, my pool is a brisk and wonderfully refreshing 82 degrees. I'm not sure how much can be attributed to the rain, as I know it did help, but these pool coolers do seem to work very well. If you have a problem with hot water I say give them a try. I would absolutely buy them again.
