I built a heat pipe from a video on youtube and placed it in the sun for only one hour and the stub of the pipe was too hot for me to hold!! very impressive

Outstanding! – Great product, Great price, Swift FREE shipping – SOLID 5 Stars!


So much fun. I used white dry sand to absorb the heat energy and the ran tubing to heat water. Works really well. We heated our mid sized pool over summer with two of these. Bonus in the fall and winter you can boil water with nothing but the sun in a couple of hours. It would be AWESOME if the include silicone plugs because I had to make my own.
