We've had an instant hot-water dispenser (by Insinkerator) in our kitchen for many years. It is a very convenient way of having near-boiling water for tea, or other uses, without the time-delay that it takes to fill a kettle and wait for the water to boil.
When our last one wore itself out, we learned that it wasn't repairable, and the model and style (and colour) was discontinued. We had to find a dispenser that we could get that was white. And there weren't too many options. So we went with this one. It was ordered from a local plumbing company, and they supplied and installed it.
It works well, looks good, and we're very happy with it.
