call me skeptical. I am not saying it can't be done. but how practical is it. the guy in the video on their website sounds like a snake oil salesman. in the video the guy goes on and on about how efficient it is but says it needs a 120v 20amp circuit to run it. excuse me but that is not efficient. that's generator or a Jimindenver size solar set up. I don't even know if his system could do 120v 20amps. the heating of the water and the UV purifier are energy intensive. granted like he touts over and over that you heat the water less because it's being recirculated but you are still heating it and then maintaining that heat. also how much does it cost nowhere on the website could I find a price. possible yes, practical? highdesertranger
