PreferablyBuying advice for instantaneous water heaters under the sink

In this section, we discuss some of the important parameters to consider when purchasing an undercounter water heater.

the one size

The first thing that comes to mind when buying a high efficiency undercounter water heater is definitely the size.

You must be very conscious of the greatness you are aiming for.

In simple words, if you know how much space a drive takes up and how much space you have available, you will definitely face fewer problems.

Do not buy a model without checking its dimensions and whether it fits well under the sink.

This way you reduce the risk of ending up buying a device that is too big for the space you have.


Well, if you choose a device with a reservoir, think about the amount of water that the device can store.

We reviewed a few models that come with tank size options.

Look for a larger tank if you have a medium to large sized home.

Kaudal (GPM)

In all honesty, the flow rate is measured in gallons per minute.

Simply put, the higher the flow rate of a water heater, the faster it can heat water.

For example, 1 GPM means the device can heat approximately one gallon of water per minute.

Even if your hot water needs are huge, you should look for a higher GPM.

Most instantaneous water heaters have flow rates from 0.5 to 2.25 GPM.

Heat output in kW

Well, heating power simply means the amount of energy it would take for the device to heat the water.

Units with a lower kW rating cannot heat large amounts of water quickly.

Simply put, how many kW you need depends entirely on what temperature level you want to heat the water to.

You can expect a greater temperature rise and faster heating of the water if you choose the higher kW unit.

What I have discussed so far relates to instantaneous water heaters.


Voltage is nothing more than the electrical requirements needed to operate the device.

It is your sole responsibility to ensure that the socket outlets you use are suitable for the voltage of the water heater.

In fact, most devices can be easily plugged into 120V outlets.

However, I will not deny that there are models that require 220V.

My point is that you may need to make adjustments to your recordings.

energy efficiency

Well, under counter heaters are more energy efficient compared to other models because they don't waste much heating energy and they store a large amount of water.

Simply checking a device's energy efficiency class will give you a rough idea of ​​its efficiency.

In fact, most devices offer energy efficiency ratings of 96 to 98 percent, which simply means they reduce a significant amount of energy loss.

recovery rate

The recovery rate is nothing more than the gallons of water that a given unit can heat.

If I'm not mistaken, the standard typically increases the temperature by 90 degrees Fahrenheit within an hour of being fully drained.

The recovery rate is measured in gallons per hour.

In simple terms, if the recovery rate for a 90 degree Fahrenheit temperature rise is 6.8 GPH, this simply means the device can heat 6.8 gallons at 90 Fahrenheit in one hour.

Put simply, the higher the recovery rate, the faster the hot water is replenished.

This is only used for water heater models that come with a tank.

security features

In all honesty, almost all of the devices we tested come with security features, making these devices safer and easier to use.

In addition, some devices come with a built-in thermostat that makes regulating the water not only easier, but also less time-consuming.

Another important safety feature is modulation, which simply means that the device can easily change the heating output in response to the flow of water passing through the device.

The advantage of this is that the water temperature remains better regulated regardless of the flow rate.

A pressure relief valve is another important safety feature to consider to prevent damage from excessive water pressure.

When the pressure is very high, the valve relieves the pressure, making it safer to use.

installation and maintenance

It goes without saying that different types of units require different types of installation and maintenance.

Some models simply plug into an outlet and are ready to go, while others require more electrical or plumbing work to get up and running.

You can also install most units.

However, my advice would be to hire a certified professional if you plan on buying a complicated model.

It goes without saying that you should read all installation and maintenance requirements before and after your purchase.


It goes without saying that price is an important factor in the purchase of any product, not just under the sink heater.

Always look for products that not only meet your needs but also fit your budget.

Believe me, the most expensive aren't always the best and the cheapest aren't always the worst.


The longer the warranty period, the better.

Always look for products that come with a wider range of warranties.

There are many, many units that offer a tangible warranty length.

However, you can require the unit to be professionally installed for the warranty to be valid.

What are undercounter water heaters?

Well, under-sink water heaters are those that are small, compact, and elegant in design, and are usually mounted under the sink to deliver hot water straight to the faucet.

They are also popularly referred to as point-of-use water heaters.

There are basically two types of kitchen sink heaters, the former that heat the water flowing through the unit and the latter that store a small amount of hot water in the tank that comes with the unit.

Trust me, you don't always need an undercounter water heater, that's for sure.

So the question becomes when to buy it, right?

If the main water heating system is far from a particular faucet, resulting in a good time to supply hot water through that faucet, you can eliminate the waiting time by installing an under-sink heater.

Another scenario is when the hot water demand is greater than the capacity of your heater and you don't want to upgrade to a larger, more powerful unit, then the additional load can be efficiently handled by the undercounter water heater.

In other words, installing these little animals will help you save money on your energy bills and reduce energy consumption.

Types of hot water systems under the sink

There are mainly two types of undercounter water heaters, namely tank and tankless systems.

Let's take a quick look at each of them.


A first option is a tank-based unit that pre-heats a small amount of water and stores it for later use.

Most tank models hold water in the 2.5 to 7 gallon range at a time.

It's definitely a great option if you want instant hot water.

On the other hand, it also helps reduce water consumption since you don't have to open the sink to wait for the hot water.

You can just plug these devices into a regular outlet and they are definitely easy to install.

This type of model can be ideal if your tap is far from central heating.

Or places where you need instant hot water in small batches.

without a tank

Another option we have is a water heater.

The best thing about instantaneous water heaters is that you don't need to store hot water, so the queuing losses would be negligible.

In fact, in the water heater, electrical filaments heat the water as it flows through the units.

And best of all, you have effortless, unlimited hot water at your fingertips.

The heater consumes energy only when it detects the passage of water.

On the other hand, a conventional water heater works constantly to keep the water tank hot.

Of course, the tankless version is small and compact, taking up comparatively less space due to its slim design.

At the same time, however, the device requires a little more setup than a tank heater.

You need to make sure you connect the wiring and connect it correctly to the existing plumbing to ensure it works properly.

Once installed, it will definitely reduce your water heating costs without sacrificing efficiency.

Benefits of an undercounter water heater

Well, there are some advantages to using an undercounter water heater.

Let's take a quick look at each of them.

compact size

As mentioned above, undercounter water heaters are small and compact.

In fact, such units do not take up much space and can be installed under the sink.

Of course, these little creatures are much smaller than conventional water heaters.

easy installation

To be honest, you don't need much electronics or plumbing knowledge to set up the unit.

Whether you are a beginner or a seasoned pro, it doesn't take much time to install.

Additionally, almost all the devices that we have reviewed in this post come with easy-to-follow instructions and guides that make the whole installation process less time-consuming and hassle-free.

Fast warm-up time

You don't have to wait for hot water because these devices can heat water quickly and instantly.

In most cases you will not notice any time delay between turning on the faucet and the water flowing.

In other words, you don't have to use the sewer by running it until it gets hot.

Constant hot water supply

You don't have to worry about running out of hot water when you use an undercounter water heater.

Therefore, these units are the preferred choice for showers, bathtubs and kitchen sinks.

energy efficient

The system will help you reduce your home's energy consumption as it requires less energy to heat the water.

Of course, they don't constantly work to maintain a large volume of hot water.

Servicing the water heater under the sink

It goes without saying that you must keep your under counter water heater in pristine condition to get the maximum benefit.

As with any other water based appliance your under counter heater is at risk of limescale build up so it is always recommended that you wash your heater at least once a year if not MORE.

Let's take a quick look at some of the routine maintenance tasks you should perform.

  • Flushing your undercounter water heater regularly
  • Regular checking of the pressure relief valves
  • Also, check for leaks regularly.
  • Check if thermostats and controls are working properly or NOT
  • Make sure all connections are tight and secure.

Although this is your first purchase, you can perform these maintenance checks yourself.

However, if you are short on time, I would suggest hiring a professional to do the work for you.

How to install a water heater under the sink?

As we've already discussed, installing an undercounter water heater largely depends on the type of model you've decided on.

For example, installing a tank-based water heater would be slightly different than installing a tank-based water heater.

In general, however, installing a POU water heater is relatively easy and quick.

You can install it yourself or even hire a professional to do it, whichever is more convenient for you.

However, unless you are used to or familiar with electrical and plumbing work, I recommend hiring a professional.

At the same time, you should also take into account that some companies only offer guarantees if the installation process has been streamlined by a certified professional, so you should act accordingly.

Installation of the tank water heater

  • First of all, you need to make sure that there is enough space under the sink to install the water heater.
  • Shut off the water supply to the sink.
  • Mount the device on the wall, on the shelf or even on the floor, depending on your needs.
  • The next step is to access the hot water connection under the sink by connecting the pipe from a heater to the pipe that goes to the faucet.
  • Plug the device into an electrical outlet

Install flow heater

  • First you need to mount the device on the wall.
  • Connect the water source to the inlet side of the device
  • To go further, you need to connect a hose to the output port of the device.
  • Also, you need to make sure that all the pipes are properly connected before proceeding with electricity and running water.
  • Depending on the device type, you need to make sure that the wiring is correct.
  • Connect the cables to the device and then connect the other end of the cables to the circuit breaker.

Note: Especially for tankless units, the installation process can be speeded up by itself if you have an idea of ​​the installation.

However, hiring a professional would indeed be a better option.

frequently asked questions

In this section, I answer undercounter water heater review questions to help you make an informed purchasing decision.

So, without further ado, let's get started...

Do I need a licensed plumber to install an undercounter water heater?

Well, it's not necessary, but if you don't want to speed up the installation process yourself, you should definitely consult a certified professional.

Additionally, some devices require professional installation to qualify for warranty use.

How does an undercounter instantaneous water heater work?

An undercounter water heater is located near a water outlet, e.g. B. a faucet, so that you get hot water immediately.

When you use an undercounter water heater, you have hot water saved for your use.

On the other hand, if you bought a tankless device, it will heat the water as it flows through the device.

How Reliable Are Kitchen Sink Water Heaters?

These little critters are definitely dependable and you can trust them blindly when it comes to your hot water needs.

How do I adjust the amount of hot water under the sink?

First you need to turn off the water in the sink.

Then locate the water control valves under the sink.

The valve on the right controls the hot water.

Turn the knob clockwise to increase the amount of hot water or counterclockwise to decrease the amount.

What kind of amp break would be needed?

In simple terms, the type of breakout amp you need really depends on the type of model you choose.

For example, if your maximum amp draw is less than 40, you only need a 1 x 40 amp breaker.

If the maximum current draw of the amplifier is 150, you will also need 4 x 40 amp circuit breakers.

Simply put, it is your responsibility to ensure that the full amperage breaker can handle the maximum amperage of your appliance.

Where is the best place to buy an undercounter instantaneous water heater?

Honestly, the best place to buy an undercounter water heater is or any other ecommerce site that you trust.
