Many people are unaware that standard hot water heaters concentrate minerals, too, and are not intended for drinking water. My parents and in-laws fill their water kettles from the hot water tap, even though filtered water is available.
- tgb 9y agoWow, I was sure you were wrong when I read this but it looks like you're right. Though the reasoning here is a little different from how I interpreted your comment. It's not that the heaters concentrate minerals by, say, evaporating some of the water, it's that hot water simply dissolves lead from pipes more easily than cold water.https://mobile.nytimes.com/2008/01/29/health/29real.html https://mobile.nytimes.com/2008/01/29/health/29real.html

- seszett 9y agoI thought it was common knowledge that hot water from the tap wasn't drinkable, but here in France the reason I have always heard is that bacteria tend to develop in the hot water storage tanks (which are set to around 60°C usually, not hot enough to prevent their development).
