on this test comparison.

I found it interesting they chose to vinegar wash the tankless, between tests, due to hard water!

Also that the warranty states below 11 grains on these tankless. Wonder how many installers know to check this and how much it can effect heat exchange and longevity.

Also check out the article on copper brazing, Dan, and Siggy.

Nice work on this issue PMEngineer staff :)
