You've been drinking hot water from the tap your whole life?

[lowercased]

as opposed to...? Are you meaning just "hot" without heating it up further somehow (kettle, microwave, etc)?

I'm not GP but what I do is

    cold tap water -> filter pitcher --> kettle
                                     `-> drinking glass

I occasionally drink cold water straight from the tap but it tends to taste bad so I try to avoid it.

Of course, there's the issue that most kettles are made of plastic or at least have some plastic components so how do you keep it microplastics-free?

There's no winning, I guess. :D
