13 key benefits of under sink water heaters

There are many benefits of under sink water heaters. We want to share with you thirteen reasons why you should consider getting your own.

What Is A Point Of Use Water Heater

Under sink water heater systems are also called point-of-use water heaters. That’s because you install such systems at the location you plan to use them or where you need them the most. You may also hear them referred to as:

instant water heater systems
on-demand water heater systems
under counter
hot water booster systems.

Where To Install Point-of-use Water Heater

The best place for under sink on demand water heaters is at far away from central water heating systems.

It takes longer for hot water to reach these faraway fixtures. So, you spend a lot of time waiting for the heated water to arrive. And during that wait, you also waste quite a bit of water while flushing out the cold water in the pipes.

Types Of Point-of-use Water Heaters

You can find a small under counter water heater in both tank and tankless models. But these devices are electric. They do not come in gas models.

Tank vs Tankless Under Sink Heater Comparison

About Tank/Storage Water Heaters (Under Sink)

- Heats small amounts of water at a time.
- Stores heated water so you can use it later.
- Comes in different sizes

Sizes range from 2.5 gallons to 7 gallons.

- Easy installation process

It is easier to install these systems than the tankless system. All you need to do is plug them in.

Drawbacks Of Under Sink Water Storage Tank Water Heaters

The capacity of these systems is limited. Once you use up the hot water, it will need to heat another fresh supply of cold water.

About Under Counter Tankless Water Heater Systems

- These systems cannot store hot water. They are not built to do so.
- They heat water on-demand when you turn on the tap.

So long as you have the water running, you will have a continuous stream of hot water.

- More energy-efficient than storage-tank water heater systems.

They only use energy to heat water when the water runs. Having this feature ensures these systems are not working continuously.

Drawbacks Of Tankless Under Sink Water Heater

These systems are small, but they are a bit more difficult to install than tank water heater systems.

This takes us right into our first benefit of getting under sink hot water heater systems.

Hot Water On Demand

An under sink on demand water heater cannot replace your whole house water heater. But, installing point-of-use water heater systems gives you hot water whenever you turn on the hot water tap.

Get Hot Water Faster

Whether you have a tank or tankless system, you will get hot water faster. The heating process is quick. You do not have to wait more than a few seconds for hot water.

Never Run Out Of Hot Water

You can install small under counter water heater systems:

- showers
- bathtubs
- kitchen sinks
- Or in any place that you use hot water regularly.

They provide a constant supply of heated water. So, you never run out.

Easy Installation Process

It won’t take you more than a few minutes to install an under sink water storage tank water heater system. Tankless systems may take a few more minutes, but it is still an easy process. All you have to do is follow the instructions in the manual your system comes with.

Some of the more high-end products may be a bit more complicated. If you have basic skills in electrical and plumbing works, you should be able to handle it yourself. Those who are excellent at following instructions may only need some DIY instructions.

For those of us who are not too savvy in these areas should hire the help of a professional.

Energy-efficient

Using a mini water heater for sink and shower purposes saves on energy because you do not need to:

wait long minutes for hot water to heat up
wait long minutes for hot water delivery

These systems also save on energy use because they:

use a lot less energy to heat water.
do not heat a large amount of water.
do not need to keep large amounts of water hot

Low Impact On The Environment

You use less energy with under sink water heater systems. Because of that, these water heaters are better for the environment.

Saves You Money

We all love cost-cutting deals, and that’s what an under sink water heater system does for you. Because of energy efficiency, these systems reduce energy costs by up to 50%.

Saves You Time

Getting a mini water heater for point-of-delivery saves you time. You no longer have to wait those one or two minutes for your whole house water to deliver heated water to you.

No More Wasting Water

While waiting for hot water delivery, the cold water has to be flushed out of your pipes. That’s money flowing down your drain pipe. But instant hot water under sink systems takes care of this problem. You have hot water whenever you turn on the tap for the heated water.

Safety Features

Some under sink water heater systems have features that make them safer for home use. These features include:

- thermostats
- heat control buttons/dials
- flow rate modulation

Sometimes, depending on the flow rate of the water, the hot water temperature changes. If the flow rate is not quick, the water becomes scalding hot. You may suffer third-degree burns. But with a flow rate modulator, the temperature remains constant. Even when the water pressure is low, the water will not get too hot.

Compact Size

A small instant hot water under sink system is sized for convenience. These devices fit in tight spaces like cabinets with ease.

Cost

Under sink water heater systems have different pricing ranges. There are some as low as US$60. But, some systems cost a few hundred bucks.

The high-end products fall in the upper hundreds. Do not despair. There are cheaper products that are still reliable. And with regular maintenance, you can get these systems to last a long time.

Easy Maintenance

Like your whole house water heater system, an under sink water heater also has a shelf life. You can ensure it works the way it should for as long as it should. The way to do that is with regular maintenance.

Lucky for us, these systems are easy to clean and maintain.
