Most people I know have an electric kettle here in the US. Every office I've been to has had one in the break room. Anyone who drinks tea or eats a lot of ramen or drinks anything but drip coffee will have a kettle.

It's really more that historically Americans have been fine with drip style coffee makers instead of drinking pour overs or tea.

I think that has more to do with Americans not drinking a lot of hot tea.

I had an instant 195 F (90.5 C) faucet in my previous kitchen which worked well for the rare times I made tea. Worked fine with a 120V circuit.

This is popular in the Netherlands (the only country in Europe where I saw this)

They're becoming more popular as word gets out. Stovetop tea kettles used to be popular.
