Summer is upon us and that means it's time to open the pool. However, I don't have a pool heater, or the desire to spend thousands of dollars on one. After surfing the net I found a solution I liked: the so called lily pad passive pool heaters, and made it better!
Why Lily Pads?
- They heat- by attracting and keeping more solar energy in the water
- They slow evaporation- by forming a barrier between the air and the water
- They are easy to use and store- just push them aside or stack them on the deck
- They're safe- no solar blanket to get tangled in or caught under
- They're cheap- ten for $35 (Pro versions will run you $25 each!)
- They're green- they use no gas or electricity to heat, conserve water, and can last several seasons
We'll be making ten 4.77' (about 4' 9.25") lily pads. That's a combined surface area just shy of 180 square feet. That should cover a good chunk of just about any residential sized pool.
This project involves hot irons, please be careful.
