How do I heat a smaller pool?
I have an Intex 10' X 30" "frameless" pool. Even though I live in "Sunny" South Fla, it is often not sunny, or I like to take a dip after work at 2am to de-stress. The pool will be ice cold half the time. I looked online at heaters, but they cost twice if not three times the cost of my pool, and I gather that they are meant for larger pools. Is there any thing out there I can try? A friend suggested putting half concrete blocks in the oven and then throwing them in the pool, but I hope he was joking.
