All good points and you are correct, accept one thing; it is not dependent on RODI in any way, i just used existing RODI tubing for easy hookups.
This can be used independently, just run water from cold tap through the heat exchange coil and drip back to the drain. No moving parts, one manual control valve for the flow and that's it. Simplicity = dependability and reliability

As for water wasting yes, it drips to the drain. However when it rains 20 days out of 30 and you don't have a water meter ... i am not that much concerned, and below are the reasons.

Have another look at this at a different angle:
No need for electric power to run this unit, but to produce power to run chiller it will take river water to turn the turbines , or burn coal, or get it from Nuclear plant and we all know how wonderfully "safe" the Nuclear power is, plus environmental impact of making aluminum, copper, plastics are highly toxic and this definitely will pollute the planet eventually. With that in mind my unit may be even more environmentally clean and friendly then buying running and scrapping a chiller.
