Compare Instant Hot Water Dispensers: InSinkErator or Waste King?

InSinkErator Instant Hot Water Dispenser(Photo Credits: InSinkErator)
If you wish to have near-boiling hot water at your fingertips for preparing quickly coffee, tea, hot chocolate, baby bottles and  hot cereal or  clean dirty pots and pans, blanch vegetables, prepare soup, etc., you might want to consider an instant hot water dispenser. No need to wait for the water to boil, no water waste, and no mess.

​Instant hot water dispensers save time and add elegance to the kitchen. They're usually made of an insulated  udersink  hot water tank connected to an elegant  faucet installed on your countertop next to your sink. They are also equipped with an easily adjustable thermostat  that allows you to select the temperature that suits you best.

​Here is how it works: Water comes up from your supply line into the hot water tank, where it’s heated. As the water is used, more water replaces it in the tank. With a fast recovery system, depending on the brand used, these systems can deliver anywhere from 50 to 100 cups of near-boiling water per hour. ​While the instant hot water dispensing faucet sits elegantly on your sink, the hot water tank sits unseen below it. 
​
Instant hot water dispensers have become a favorite among homeowners for three main reasons:
  • They speed up the preparation of meals and hot beverages.
  • Their low energy consumption saves money.
  • They save water because there is no time wasted for the water to heat up.

Various studies have shown that with an instant hot water dispenser used to provide near-boiling water can save up to 75% of the energy normally required to heat water to near-boiling temperature.
​

This article will compare InSinkErator Involve H-Wave and Waste King (Anaheim) H711-U instant hot water dispensers. These were not just the most popular among Amazon customers at the time this article was written, but they had also received excellent reviews from most Amazon buyers.

  • InSinkErator also makes the F-1000S filtration system designed for use with the InSinkErator hot water dispensers.
