Just a thought..... We had a above ground pool with the water temperature in the 60's and our young kids begging me to jump in, I had to rethink what I had done setting up that pool.

I took a large car radiator, placed it in the attic with a fan blowing across it and pumped the cold water thru it. The pool got up to 90 degrees in about a week. Before the heat exchanger, the attic was around 130 degrees and higher. After that, the house was a whole lot cooler.

I thought I was going to be rich until I did an internet search and found that there was a patent on it already.
