I know that really pure water is actually corrosive and will do it's

current will cause an etching or eroding effect of the materials in the

I will changing? out the water.? Could be after only 10 hours of use, or
it may be 100 hours and the cooler may rot out in no time.


Just wondering out loud... I'd bet some cars have either all-plastic radiators, or, maybe plastic heater cores for the A/C. Maybe that would remove the issues of metal ions from the heat-exchanger. Undoubtedly less efficient at removing heat from the water than metal, but size cures a lot of ills.
