How do instant hot water dispensers work?


There are different types of instant hot water dispensers that you can choose from. The most common ones are the under-sink hot water dispensers and the countertop standalone ones.

The under-sink units need to be connected to the cold water supply line and have their own faucet, which will provide you with instant access to hot or near-boiling water.

They have hot water tanks and heating elements which heat up the water to the temperature you have set and maintain it at that temperature.

Once you start using the hot water, the device will automatically add more water to the tank, which will be heated.

These units have thermostats and are very convenient because you don’t have to wait for the water to heat up, and you can have access to the hot water you need at any time.

The negatives are that they require that your sink or countertop has a hole for the faucet and can be more expensive than the countertop ones.

The countertop instant hot water dispensers are standalone appliances that do not need to be connected to a water source and can be placed anywhere.

They have different capacities and will heat up the water and maintain its temperature a tad slower than the under sink ones, but they are a perfect choice if you don’t want to drill holes on your kitchen countertop or sink or if you want a more portable and affordable solution for your home, office or other space.

These standalone hot water dispensers do need to be refilled manually.

What are the benefits of owning an instant hot water dispenser?

You may think that buying an instant hot water dispenser could be a bit of an overkill, but the truth is, there are many advantages of owning such an appliance, some of which you may not be aware of.

Here are some of the benefits of owning an instant hot water dispenser:

It saves energy and thus saves money

Even though some of the premium quality instant hot water dispensers are pretty expensive, in the long run, they can actually help you save money for electric power bills.

If you tend to use an electric kettle, microwave, or an electric stovetop to boil water for your tea, coffee, or other needs, you are probably using quite a lot of electricity.

Instant hot water dispensers are energy efficient and will use up minimal electricity to heat up and maintain the temperature of the water.

Plus, you won’t have to turn on the kettle or stove for every single cup of tea you are making with one of these dispensers in your home or office.

You will have near-boiling water at any given moment

This is a serious advantage, especially if you live or work in an environment where there are a lot of people drinking tea, coffee, making soups, oatmeal, or other beverages and meals.

With an instant hot water dispenser, you can make a steaming hot cup of tea at any moment, without having to wait for it to heat up and boil and without switching on a kettle or stove.

You can use the hot water from the dispenser for numerous purposes

Apart from preparing hot beverages and instant soups and breakfast, you will find that the near-boiling hot water can come in handy for various other purposes, including:

  • Soaking and washing greasy pans, trays, and utensils without using harsh detergents
  • Heating up the water to the desired temperature with precision
  • Warming your baby bottles
  • Opening stuck jar lids
  • Removing stickers and labels from bottles, jars, and others
  • Cleaning and disinfecting your home
  • Washing food products
  • Help kick start your cooking and food prep by using the hot water for boiling, steaming, and cooking

It can help you stay properly hydrated

If you find it tiresome to start the kettle every time you want a cup of tea with an instant hot water dispenser, you will not have this problem anymore.

This can help you drink more tea or other hot beverages and thus stay hydrated throughout the day.

It has a large capacity

If you are entertaining guests, or working in a large office, or have a big family, you may find that the electric kettle is not sufficient to prepare hot beverages for everybody per one filling of the kettle.

With an under-sink instant hot water dispenser, which is connected directly to your cold water line, the tank will be topped-off immediately when you use some water so that you will have access to sufficient quantities of hot water at all times.

It can save space

If you choose to buy an under-sink unit, you will save a lot of countertop space in your kitchen or office.

This is good news for those of you with limited space and for those looking for ways to minimize the clutter in your kitchen.

Features to look for when buying an instant hot water dispenser


If you are still not sure how to choose the most suitable instant hot water dispenser for your specific needs, here are the main features and the factors to keep in mind to make the right choice:

The material of the water tank

The material used for the tank, as well as for the heating elements and other essential parts of the dispenser, is crucial for several reasons. The first is your safety, and the second is for financial reasons.

Even though hot water dispensers with stainless steel tanks and elements are more expensive than those with rubber tanks, they are much more durable and will serve you for longer.

Also, stainless steel is corrosion-resistant, and also is food safe, so you don’t have to worry about your water being contaminated with harmful metals, chemicals, and other pollutants.

The power and capacity of the dispenser

Nearly all instant hot water dispensers have tank capacities of 1/3 to 2/3 gallons of water. And their power is from 500 up to 1,300 watts.

The more the power of the dispenser, the more cups of hot water per hour it can produce.

Choosing the appropriate power and size of the dispenser depends on your hot water usage.

If your household is small and you will not be using the dispenser excessively, you may want to save money and buy a smaller capacity and less powerful unit.

On the other hand, for large homes and for offices, it makes sense to invest in a more powerful unit with a larger capacity, which will be able to satisfy your needs for hot water.

The ease of use and ease of installation

If you want the easiest to install a hot water dispenser, then you may want to opt for a countertop unit. These do not require any plumbing or drilling, but they do need to be refilled manually.

As for the under-sink units, we have picked the ones which are the easiest to install and easiest to set. Most of them come with everything you will need for connecting them to your cold water line.’

Also, they are easy to use and have user-friendly dials and controls for setting the thermostat.

The spouts or faucets

If you are planning on buying an under-sink instant hot water dispenser, you should consider the design and type of faucet or sink top spout it comes with.

Some units come with faucets for hot and for cold water, and others come with just hot water.

Keep in mind, that you will have to drill a hole on the countertop or sink in order to install the faucet. If you have a 3-hole sink, then you can install it without the drilling needed.

The safety

Having instant access to near boiling hot water can be dangerous, especially if you have children, or tend to be a little clumsy. This is why it is important to choose a hot water dispenser that has safety features, like a faucet that locks, or needs to be lifted, pressed, or held when in use.

Some of the instant hot water dispensers have safety valves, as well as automatic shut-off functions that switch them off if the tank is empty.
