We love our instant hot water. While updating our kitchen, I insisted that we add an instant hot. After a lot of searching, we found this one reasonably priced in a hardware store. My husband even comments on how much use we get out of it - tea, pour over coffee, quicker boiling water for the stove, the kids even use it to make Ramen Noodles.

The only thing that would make this better is if the button was to the left instead of to the right of the faucet.
