Editor's Note: I recently had a child and fell in love with an instant hot water dispenser. When my daughter cried for her bottle at 2:15 am, it never let me down. It effortlessly dispensed plenty of water with the touch of the lever. 

I have since moved and the new one is not hooked up. So when the baby cries, there is a 3 minute lag time between heating and feeding, an eternity in baby time. I am sure you have bigger challenges in your renovation than mine. However, you can buy one fairly inexpensively, so consider it. This article will talk about the different instant hot options, but first lets describe what it is.

Instant Hot Water Dispenser ("Insta Hot")

An Instant hot water dispenser consists of a faucet, which there are many styles, and a hot water tank. It uses roughly the same energy as a 40-watt light bulb according to InSinkErator, a company who specializes in hot water kitchen sink products.


Different Styles

I have been selling instant hot water devices for decades now and boy, have things changed! First of all, they have gotten much better looking. The original Instant Hot, I think it was called "The Hot One" was pretty stodgy yet effective...sorry but it was. There were no choices of finish or style. Do you want to see one? Here it is.


Today, we have endless choices of style and finish! Modern and traditional in finishes to match most of the faucets for kitchens. Many different brands make their own versions such as InSinkErator, Franke, Rohl, Everpure, and Waterstone, to name a few.

They come with one or 2 handles. The hot and cold versions are most popular as the cold is filtered (not to be confused with chilled) water.

The heating tank is small enough to put under most kitchen sinks. They hold under a gallon of water but will produce 60-100 cups of water that is just under a boil per hour. They range in temperature according to what brand you buy, from 140 degrees to 210 degrees farenheit. Note that water boils at 212 degrees farenheit or 100 degrees celsius. 


Different Uses

So what do we use them for? Why would I want one? I began my research and was amazed at what I found out. I used to sell them based on the obvious uses like...

The Ubiquitous Ramen Noodle cup:


Baby food and warming baby bottles:

A perfect cup of tea and Instant Oatmeal for breakfast:

Then it started getting interesting... I talked to people who used them for cleaning without any chemicals. People were using them to clean:

  • Marble and granite kitchen counter tops
  • Baby binkies
  • The mouth piece on a trumpet or trombone
  • The inside of their refrigerator

All chemical free!

Or how about the extreme luxury of simply warming your coffee cup so it stays as hot as possible?


A Master Bedroom Kitchenette is a great place to use an instant hot water dispenser. You could use this for a French Press in the morning or a cup of Sleepy Time tea before bed.


Here are a few sleek instant hot water dispensers to consider:


  • Waterstone 1100HC $530.00-$590.00 depending on finish plus hot tank and filtration


  • Waterstone 1400HC $465-495.00 plus hot tank and filtrationrohl-insta-hot-kit.png
  • Rohl makes this kit in many finishes and includes hot tank and hot filter $1,500.00


The conclusion to my investigation is that instant hot water dispensers are much more useful than years ago. Think of hot water that is just under a boil for sterilization without the use of chemicals, warming your cup before a hot beverage is served, or quick cooking ideas.

Sure you can always use a burner or your microwave, but instant hot dispensers are faster and more accurate than any other appliance.

A few review sites have placed this at the bottom of their articles. So here is our take: Our mission is to find reliable products for you to buy. Other review sites may say this as well.

However, we don’t love every product. Quite frankly, it costs us way too much money in repair costs to support less reliable brands.

In fact, we sell fewer brands than most appliance stores. Here is why:

We feel it is our responsibility to repair your appliances after you buy them.

We now have 30 service technicians, each averaging 8-10 calls a day Monday through Friday, plus another 110 on Saturday. That's over 30,000 service calls logged in one year.

The labor rates of fixing an appliance do not come close to the true cost in any product’s warranty period.

That is why no major retailer has a service department. It costs too much labor, money and time.

Our Blog is a bit different than most others you will read. We cannot write glowing reviews of unreliable products.

Hopefully, the bloggers and organizations who write such glowing product reviews for every brand consider servicing these products first. Only then they will understand the consequences of their marketing.
