How Do Instant Hot Water Dispensers Work?

Obviously, the tank of the hot water dispenser is constantly connected to the sink’s cold-water supply. The tank is usually mounted under or on the edge of the sink, depending on the available place.
The hot water tank dispensers will start heating water, keeping it at a near-boiling temperature as soon as it enters the tank itself. Then, when you use some of the water stored inside the tank, the system will begin to replace the lost water with cold water that is quickly heated inside the tank.

Naturally, the tank is equipped with a thermostat that monitors the temperature of the water and, thus, guides the heating element inside it. It is considered the best alternative to hot water supplies and systems as you don’t have to manually fill the tank with water.

Why Do You Need an Instant Hot Water Dispenser?

instant hot water dispenser reviewsWell, instant hot water dispensers come with a lot of advantages. They provide you with hot water constantly, right? Of course, this is not everything that an instant hot water dispenser can do for you. First of all, you save a lot of time, whether you have one installed in your workplace or at home.
You can say goodbye to kettles and to waiting for the microwave to heat up your tea water. Moreover, the best instant hot water dispensers are built to be energy efficient – they always use a lower level of energy in order to keep the water warm. Naturally, the use of a microwave or of a kettle every time you need hot/warm water can prove itself a lot more expensive than an instant hot water dispenser.

Furthermore, the capacity of the tank is quite a benefit – with a kettle, for example, you can heat up only a limited amount of water. However, an instant hot water dispenser always comes with a tank that can fill at least a couple of gallons of water. Therefore, when you need warm/hot water, you’ll probably never have to wait for the tank to refill itself and heat up water. Of course, since most instant hot water dispensers out there provide you with near-boiling water, you will always have a cup of water that’s just perfect for making tea or coffee and drinking it straight away.

best instant hot water dispenser

Now that we finished the list of the best instant hot water dispensers we could find, it’s time to provide you with the promised information – namely, everything you should know in terms of hot water dispensers.

Instant Hot Water Dispenser Buying Guide

In the following lines, we have compiled a buying guide for you so that you’ll know what to look for when buying instant hot water dispensers – it’s important that you take notes, as a hot water dispenser system can be used for a very long time; therefore, you’ll want to buy the one that fits you and your kitchen the best.

What to Consider When Buying an Instant Hot Water Dispenser

When it comes to instant hot water dispensers, the models you can find on the market don’t vary that much. You have a compact unit that holds the interior tank and via a heating element, it heats the water at the desired temperature.

They also have a control dial/switch on the outside that allows you to control the temperature of the water or turn off the instant hot water dispenser. Of course, the thermostat is one of the main parts of such a product, as it is the one that’s in charge of turning off the heating element when the water reaches the desired temperature.

The thermostat is reportedly also the element that is most likely to fail – you can’t really make your choice based on the thermostat inside the tank, but most manufacturers out there will fix the issue or provide you with a replacement if something goes wrong.

Tank Material

The most common material used for instant hot water dispenser tanks is stainless steel. Naturally, it is also the material that lasts the most, especially when compared to the rubber bladder tanks.
It’s true, the tanks made of rubber bladder will usually cost less than the stainless-steel ones, but they are more likely to give out within the first year of purchase – that’s why we recommend having a stainless-steel tank for your instant hot water dispenser.

The Size and Power of the Tank

Most instant hot water dispensers out there come with a tank that can hold up to 1/3 or ½ gallons of water. In terms of power, it ranges from 500, to 750, and to 1300 watts. For example, a 750-watt and ½-gallon tank will produce around 60 cups of hot water per hour. Naturally, tanks with more power can even produce up to 100 cups of hot water per hour – when it comes to this, preferences matter the most. If you are usually using a lot of hot water during the day, then you might want to choose a bigger tank or one that can produce more hot water cups in a day.

Faucets – aka Sink-Top Spouts

Most instant hot water dispensers don’t come equipped with a faucet – however, our list of products does contain more than a few dispensers that come with a classy faucet as well. Again, this depends on your preferences – for example, you might want to have a faucet for cold water and one for hot water. So, you may have a faucet connected to a water cooler. Thus, you’ll want one more for the instant hot water dispenser.

Now that you know what to look for in an instant hot water dispenser, it’s time you learn some things about the installation process as well.

How Do You Set Up an Instant Hot Water Dispenser?

In order to install an instant hot water dispenser, first, your sink top must have a hole that can receive the spout of the instant hot water dispenser. Therefore, most hot water dispensers are usually installed during the remodeling of the kitchen, when you are yet to buy a sink.

However, you do have some alternatives in case your sink doesn’t have an extra hole – for example, if your sink has a sprayer you could remove that and use its hole for the instant hot water dispenser. If you are desperate and still haven’t found an available hole, you could ask a plumber to drill a hole in porcelain or stainless steel, depending on the sink.

After you have everything you need, just follow the next steps.

  1. The dispenser spout has to be inserted through the sink’s hole and tightened in place from underneath with the help of a large nut.
  2. Then, the tank has to be mounted under the sink or onto the cabinet wall, depending on the model.
  3. The tank then has to be connected to the water supply pipe – a saddle valve can be clamped on the cold-water pipe in order to tap into the tap water supply. Then, you can connect the appliance to this valve using ¼ inches of copper tubing and compression fittings.
  4. Finally, the spout has to be connected to the tank; usually, the spout comes with two plastic tubes that deliver water from the tank – one is red for hot water and one is blue for cold water. Their connectors have to be plugged at the top of the tank.

The Bottom Line

Now you now know everything about these products – from the information provided by our list of instant hot water dispenser reviews and the complete buying guide. You also know the benefits that come with an instant hot water dispenser – namely, the time and money you can save if you decide to install such a gadget in your kitchen.
