It's just one tap at that sink, clearly identified, in addition to the regular hot & cold water taps. I don't run my main hot water tank at 195F, that would be dumb.

So you have an auxiliary heater at the tap? How is energy delivered to this system?

Yep, I have a separate tap at the kitchen sink which is connected to a small (about 3 liters IIRC) tank underneath. I have it set to 195F, though it can be set as high as 210F. There is a receptacle in the cupboard under the sink where it plugs in.

I'm curious, do you know how many kwh that uses in a day?

Exactly my thought. Sounds like a costly convenience.

We put one in 15 years ago and use it every single day. Sorry for the commercial link, but https://insinkerator.emerson.com/en-us/insinkerator-products... is an example. It's great to have near-boiling water on demand.
