Not worth it. A temperature controllable kettle that shuts itself off and can keep water warm is both incredibly convenient and far more safe.

I have a temperature controllable "kettle" (tank) under my sink connected to a tap and I get water at 195F. I agree on the convenience. They are pretty common.

lots of new induction hobs have "boil detection" and auto shut off, fwiw

So I just need to upgrade my current induction stove to a newer model? That seems reasonable... ;)

But no whistle! Good point on safety though
