Buying Guide

Now that you’ve seen our instant hot water dispenser reviews and know more about some of the best instant hot water dispenser models on the market, it’s time to take a closer look at what these devices really do and how to choose between them. Read on through our buying guide and FAQ section to learn all about what hot water dispensers do, what advantages they offer over kettles, and what factors you need to think about in order to find the perfect model.

What the instant hot water dispensers for?

5 Best Instant Hot Water Dispensers - When There Is No Time To Wait

First of all, before you invest in an instant hot water dispenser, it helps to know exactly what these products are used for and what kinds of benefits they can offer. As the name suggests, an instant hot water dispenser is able to provide instant hot water. Unlike a kettle, which takes time to heat water up, an instant dispenser can give you hot water in a matter of seconds at very high temperatures, even going above and beyond 200 degrees F.

Naturally, one of the most obvious uses of an instant hot water dispenser is for preparing hot drinks. Instead of having to wait around to prepare some coffee or tea, you can simply activate the dispenser and prepare your drinks immediately. This can save you a lot of time in day to day life, and there are many other amazing uses of an instant hot water dispenser too.

Families can get a lot of use out of an instant hot water dispenser for things like warming baby bottles, making Jello, or making hot chocolate. It can also be super effective for cleaning purposes, helping you to clean up greasy pans and plates in an instant or clean up containers before placing them in the recycling. Stubborn stains can vanish in an instant with some super-hot water and soap applied.

On top of all of this, an instant hot water dispenser also has many applications for cooking. You can use it to clean fruits and veggies while preparing dishes and desserts, or for making soup. You can also use it to get a head start on preparing noodles, pasta, and other dishes involving hot water. It can be great for boiling eggs, hydrating dried foods, thawing meat, warming up syrups and jams, melting butter, blanching vegetables, and much more besides.

Instant hot water dispensers vs kettles

A lot of people hesitate between getting an instant hot water dispenser and a kettle. It’s easy to understand why this is such a common comparison, as both devices perform similar functions. They’re both used to provide hot water for things like coffee, tea, and more, but when it comes to hot water dispensers vs kettles, there’s only one clear winner.

Instant hot water dispensers have a lot of advantages over classic kettles, beginning with the obvious fact that kettles need time to heat up the water, while instant hot water dispensers can offer super-hot water in a matter of seconds or even instantaneously. Some kettles need several minutes to heat just a single liter of water, but instant hot water dispensers can do the job in a fraction of the time.

This means that instant hot water dispensers are generally way more convenient and useful to have around the home than kettles. Whenever you feel like you want a cup of coffee, you can have it instantly with a hot water dispenser, saving you a lot of time. Plus, the speed and practicality of hot water dispensers makes them so useful in many other ways.

For example, as stated above, instant hot water dispensers are perfect for many uses like heating up noodles or pasta, melting some chocolate for pouring over a dessert, heating up a baby’s bottle, and more. To do these same things with a kettle would be very time consuming and frustrating.

In terms of energy usage, there really isn’t much difference between kettles and instant hot water dispensers. The exact results can vary depending on the model in question, but in general, they use roughly the same amount of energy to heat the same amount of water. However, a lot of water heated by kettles goes to waste, because you don’t usually use every single drop inside the kettle, and this helps hot water dispensers to be more efficient overall.

 

Features to consider while choosing an instant hot water dispenser

Before you decide to buy any instant hot water dispenser, you should think about a variety of factors. Be sure to read through an instant hot water dispenser review of your chosen model and consider a range of factors, including the tank capacity, the dimensions, the ease of installation, the warranty, and the temperature range of your chosen hot water dispenser.

These factors can all have an influence on how satisfying and useful the model actually turns out to be in practical use, and it’s important to think about which factors matter the most to you. Someone who likes to have protection for their purchases, for example, will favor a model with a long warranty, while someone living in a large household will probably favor a model with a big tank capacity and high number of cups per hour.

Tank capacity and number of cups per hour

5 Best Instant Hot Water Dispensers - When There Is No Time To Wait

One of the most important factors you should think about first of all when reading under sink instant hot water dispenser reviews or comparing different hot water dispenser models is the tank capacity and number of cups per hour. This basically tells you how much water the dispenser can store in the tank and dispense throughout the day.

The higher the tank capacity, the more hot water you and your family can enjoy from the instant hot water dispenser. It’s always wise to think about how many people are in your household and how often you have guests over in order to find a model that works for you.

 

If you tend to make lots and lots of hot drinks for friends and family, you’ll need to invest in a model with a high capacity and plenty of cups per hour, like the Westbrass D271H-12, for example. However, if you live in a smaller house or don’t tend to use too much hot water, a lower capacity may be more than enough for you.

Faucet

All of the best instant hot water dispensers come with faucets, and you’ll need to think about various aspects of the faucet design when choosing the right instant hot water dispenser for you.

Some instant hot water dispensers come with faucets in various colors, metals, and finishes, like the solid brass plated faucet of the Westbrass HotMaster DT1F271-07, for example. Faucets can also be found in different sizes, like the chrome faucet of the InSinkErator H-CONTOUR-SS.

It’s important to think about the overall design and aesthetic style of your kitchen when trying to choose the right instant hot water dispenser for you. It’s always better to find a faucet that matches up with your kitchen’s style and doesn’t look out of place.

You should also think about the size and shape of the faucet in your instant hot water dispenser and be sure that it can fit perfectly above your sink without touching any cabinets or interfering with any other parts of your kitchen’s design.

Temperature range

The whole point of an instant hot water dispenser is to provide hot water instantly to the user, so the temperature range of each model can be a very important factor to think about. You see, not all instant hot water dispensers are able to reach the same temperatures. Some of them can get a lot hot than others, like the Ready Hot RH-200-F560-CH, which is able to go up to 200 degrees F.

The wider the temperature range, the better your instant hot water dispenser will be at helping you make lots of hot drinks and perform various other tasks around the home related to cooking, cleaning, and more. It’s always good to find a model that can hit very high temperatures, as super-hot water can be very helpful in so many situations.

If you can find an instant hot water dispenser with a broad temperature range, this gives you the most flexibility. You can turn the water down to a cooler setting for certain tasks, like heating a baby’s bottle, for example, and then crank it up to a higher temperature when you need to scrub some tough grease stains out of a pan or prepare some piping hot coffee to share with your friends. The wider the temperature range, the more versatile your dispenser will be.

Tank dimensions

5 Best Instant Hot Water Dispensers - When There Is No Time To Wait

Another big thing to consider when reading any best instant hot water dispenser review or shopping for your next hot water dispenser is the size of the water tank. Typically, a hot water dispenser will come in a kit with two main parts: the faucet and the tank. The faucet sits on top of the sink and dispenses the hot water out wherever you need it, while the tank is mounted under the sink and connected to plumbing and electrical connections to provide hot water.

Tanks for instant hot water dispensers can come in a range of shapes and sizes, and it’s so important to think about where you’re going to install the tank and check that it will fit just right in your chosen area.

 

It can be a real disaster if you take the time to invest in an instant hot water dispenser and then realize you don’t actually have enough space for the tank to be properly installed.

Some of the best instant hot water dispensers out there have quite compact tanks that are still able to offer impressive capacities and cups per hour ratings. The InSinkErator H-CONTOUR-SS, for example, has quite a compact and convenient tank that is really easy to install and still capable of storing 2/3 gallons of water and offering up to 60 cups per hour of hot water for you, whenever you need it.

Price

One more factor you definitely can’t ignore when shopping for any instant hot water dispensers is the price. It’s always important to think about how much you want to spend when buying pretty much anything in life and setting out a budget that works for you. Interestingly, the prices of instant hot water dispensers can vary quite a lot, and you don’t always have to pay big bucks to get a great quality model.

There are some very expensive models of instant hot water dispensers out there, including some units that go above the $500 mark. However, it’s also possible to find a lot of great hot water dispensers for less than $200, like the Waste King H711-U-SN and the InSinkErator H-CONTOUR-SS, for instance.

Warranty

Be sure to consider the manufacturer warranty of your chosen model whenever you shop for an instant hot water dispenser too. This can really help to provide a lot of peace of mind for you when using your instant hot water dispenser each day, as well as keeping you covered in terms of repair and replacement costs if ever your faucet or tank breaks down and needs to be fixed.

When it comes to instant hot water dispensers, some manufacturers are much more generous than others in terms of the warranties they provide. There are many models that only come with a single year of coverage, which isn’t a lot, but other units, like the Ready Hot RH-200-F560-CH, for example, come with three whole years of protection from the manufacturer, ensuring that they’ll be the ones to handle repairs and replacements, should you need them.

More features

Last but not least, one final thing you should consider when shopping for instant hot water dispensers is the presence of any additional features or extras included with each kit. These little bonus features can actually make a big difference to the overall functionality and efficiency of your chosen dispenser, making it more fun and enjoyable, as well as more useful.

The Westbrass HotMaster DT1F271-07, for example, comes with digital functionality, six preset temperature settings, and even a filter to clean and purify the water as it is dispensed via the faucet. The InSinkErator H-CONTOUR-SS, meanwhile, offers tool-free connections on the tank for super speedy and easy installation, as well as truly instant hot water dispensing.

How to install your instant hot water dispenser system

5 Best Instant Hot Water Dispensers - When There Is No Time To Wait

Once you decide to buy the best rated instant hot water dispenser for you, you need to think about how exactly you’re going to install it. The exact specifications and steps to follow will vary from model to model, and many of the best hot water dispenser manufacturers will always be sure to include instruction manuals in the box that show you exactly what to do. In general, you should follow these simple steps to get your instant hot water dispenser up and running with ease:

  • Turn Off The Supply – The first thing to do when installing your hot water dispenser is to turn off the water supply. This ensures that you won’t have to worry about any potential leaks or other issues occurring due to the water running during the installation phase.
  • Unpack Everything – Next, be sure to unpack all the different components of your instant hot water dispenser kit from the box. Check that everything is there and read through the instructions provided to get an idea of how to install your unit and how it should work when it’s all set up.
  • Mount The Faucet – The next step of hot water dispenser installation is to install the faucet itself. This is a key part of the procedure and needs to be done with care. Be sure that the seal is properly placed on the dispenser and that it fully surrounds the mounting hole to avoid any kind of leak when the faucet is turned on. Next, tighten the faucet in place from underneath.
  • Mount The Tank – Once the faucet is all set up, you’ll need to focus on mounting the hot water tank, which is one of the most important parts of your instant hot water dispenser and responsible for heating the water. Be sure to install the tank in a vertical position and keep it level. Place it somewhere where the plumbing and electrical connections can easily be made to provide the tank with water and power.
  • Finish Off – To finish off the installation process, you’ll need to connect the plumbing and tubes to your tank, as well as fitting a filter system, if you have one. You shouldn’t plug the unit into an electrical outlet until the tank has been filled up with water to test that all the connections are watertight and nothing will leak. Then you can finally plug everything in and switch it on.

FAQ

This really depends on the model you buy. There are many different hot water dispensers out there and the noise levels of each model can vary quite a lot.

It’s always a wise idea to hook your instant hot water dispenser up to a filter system if you want to drink the cleanest and purest water possible, as filters work to remove impurities and improve the flavor and odor of water in your home.

Yes, it is possible to install an instant hot water dispenser like the Waste King H711-U-SN in your RV, but there are a few things for you to be aware of before going down this road.
