Recommendations for Belgium: do not drink the hot water

For Geneva: you can drink the hot water

For France: you can drink the hot water but it is disgusting

All of them talk about the same effects (fisdolved oxygen, piping ,...) and come to different conclusions.

My take on that: nobody questions the potability of cold tap water so I will use that one, there is nothing to gain (possibly a shorter time to boil? that trumps the extra cost?)
