The only thing that might prevent some people from buying is its size.

One of the first things we noticed while testing it was the fact it used less power than the average lightbulb. Since it’s an amazing energy saver, it will reduce your monthly bills and save your money in the long run.

But, let’s not forget to mention its included faucet. At first, it’s sleek and beautiful design looked great anywhere we installed it.

This dispenser is visually different than its peers in that it doesn’t have an overly beautiful or elegant style. Instead, it is rather plain and white, but it provides excellent quality and efficiency. Fortunately, this model also comes with a gooseneck faucet which makes it nice and easy to use.

The first thing that we noticed about this product is its higher price compared to other brands of hot water dispensers. While this can be a bit off-putting, it does provide fantastic quality for the price, which is a big plus. Like most InSinkErator dispensers, this unit also comes with a stainless steel tank of ⅔ gallons.

The unit provides instant hot water, which makes it ideal for various beverages. It’s an excellent choice for making coffee or tea in half a minute.

This unit is an excellent device if you frequently need hot water throughout your day. It comes with a beautiful chrome faucet and features adjustable temperature control. The water it provides is almost at boiling temperature, so it’s an excellent choice for coffee or tea.

Another thing that we like is how easy it is to use. The unit comes with a twist-top handle and is very simple to install.

This product improved on its older version in a few ways, including:

  • It has a tall & curved faucet,

These features make it more visually appealing, and the seller’s attention to details like including an adapter for the mainline has kept customers satisfied with this model.

There have been other issues with this product, including instances where it failed to reach proper temperature settings ( 175°).

What We Liked:
  • Good quality faucet
  • Easy to install
  • 210 Degrees maximum temperature
What We Didn't Like:
  • Warranty could be longer

Customer Reviews

The customers highlighted the following features to be the best:

  • Rating: The average rating of this product is 4.3 on Amazon.
  • The faucet: Curvy and high faucet placement. The height of the faucet allows a wider area to place a taller teacup.
  • Push lever: It has a wide push lever. Usual dispensers have a twist or are not wide enough.
  • Another favorite feature: The smooth and satin nickel finishing.

However, some of the customers complained about the sputtering of water which is typically a sign of poor welding between the copper and PVC tubes. The quality of pipes fitted under the sink is also questionable since it takes minimal force to cause 

Another frustration customers experienced was that some of the necessary fittings for installation were missing in their shipment. Some of the complaints also stated that the dispenser is noisy and that scheduling maintenance with customer support is a hassle.

When it comes to durability concerns, InSinkErator has not lived up to the mark. In some cases, customers have had to replace these dispensers with an older model of this brand several times within a short span of time.

If you do want to give this dispenser a shot, buying it from the link above may save you from fraudulent online shops.

The faucet is durable and simple to use thanks to the smooth movement of its handles and the faucet neck pivot.

There is also a safety lock on the hot waterside, which is perfect for keeping small children from getting scalded.

One possible drawback could be that the hot water tube is made of silicone and positioned right next to the cold-water pipe.

What We Liked:
  • A very nice and high-quality faucet. 
  • Inexpensive 
  • Good build quality
What We Didn't Like:
  • The instruction manual is not beginner-friendly.

The customers highlighted the following features to be the best:

  • Rating: The average rating of this product is 4.1 on Amazon
  • Installation: It only requires a single person to install it
  • Flow rate: The flow of hot water is steady which reduces the risk of hot sputters
  • 2 in 1 dispenser: Dispenses both temperatures of water at the same time, providing warm water
  • Other favorite feature: Quality-wise the product is durable

Few complaints have surfaced about some of the assembly parts being defective but the labeled hardware in the packaging could be different in the package.

It was noted that mineral residue in your water supply can affect the thermostat so it is recommended that you use filtered water when operating it.

5. Rosewill Electric RHAP-16001

  • Capacity: 4 liter
  • Automatic Temperature Settings: 140, 175, 208 degrees 
  • Timer: N/A
  • Material/Finish: Stainless Steel
  • Power Source/Voltage: Corded electric/120 volts
  • Warranty: 1 year
dual dispense speed of Rosewill electric hot water boiler
  • It is for heavy-duty work.
  • The performance of this unit varies depending upon different situations.
  • Since this is a tankless instant hot water dispenser, it requires a manual refill after use.
What We Liked:
  • Affordable
  • Easy to install & use
  • Fast boiling
What We Didn't Like:
  • The metal used in this product is rust-prone
  • Not very durable

Customer Reviews

  • Rating: Customers rated this dispenser to be 3.8 stars. Amazon ratings suggest that the product is very cost-effective.
  • Customer service: Good on account of returns under warranty.

To increase the durability of this product, use filtered water to avoid damaging mineral deposits. Rust deposits can settle under the stainless steel lid if you live in a hard water area.

While this machine is designed to provide constant boiling hot water, it isn’t overly durable. It works fine for the first 6-8 months and then starts showing minor defects. It is still considered a handy product to have at home and doesn’t require much counter space.

According to our sources, these machines last up to a year which makes their price-tag reasonable.

4. Oneinmil Countertop Water Cooler Dispenser 

Oneinmil

Specification List:
  • Manufacturer:  Aoxun
  • Capacity: Unknown
  • Automatic Temperature Settings: N/A
  • Timer: N/A
  • Material/Finish: Steel
  • Power Source/Voltage: Corded electric/110 volts
  • Warranty: 1 year
space saving hot water dispenser

This is a compact unit that you can place over a countertop easily because it requires no plumbing to set up the dispenser. You will use a 2 – 5 gallon water bottle to act as its water supply even though this countertop water cooler dispenser has two small built-in tanks. They fill up with the water flowing from the big mounted water-bottle. This unit provides hot as well as cold water and has three indicator lights that indicate heating, cooling, and power.

What We Liked:
  • Silent operation.
  • Fits in smaller spaces
  • The heating/cooling of water takes about 5 minutes.
What We Didn't Like:
  • Lower quality materials

Customer Reviews

Ratings for this product is an average 3.5 stars. Usually, countertop dispensers don’t have the capacity to hold 2-5 gallon water bottles. This capability makes it a strong quality unit to buy for your home or office and can also dispense water from 4 to 5L bottles.

Being handy and of strong capacity gives this product a performance edge compared to other models on the market today. The only negative aspect of this product is its water pressure when dispensing. It can be slow compared to other available products because filling a cup with hot water can take longer.

3. Waste King H711-U-SN

  • If used with 80-90% temperature setting can last 5+ years
What We Didn't Like:
  • Difficult installation.
  • Lower quality than earlier models.

Customer Reviews

Faucet leakage has been occasionally reported in this dispenser, and installation requires the help of a professional. The instruction guide that comes with it does not provide elaborate detail on how to assemble this product correctly. This fact is probably why it has a rating of 3.3 stars on Amazon.

Despite these initial issues, this product is very cost-effective and how a great performance for the low price. We also found that compared to similar products, this unit is very durable and may last up to five years of use. Great customer service in case of replacements or returns has also been reported.

2. Costway Instant Dispenser

Specification List:
  • Manufacturer: COSTWAY
  • Capacity: 5 liter
  • Automatic Temperature Settings: 5 Temperature settings
  • Timer: Up to 9 hours
  • Material/Finish: PP + Iron wire drawing + Stainless steel
  • Power Source/Voltage: Corded electric/120 volts
  • Warranty: Unspecified

This is a very good product capable of holding a large water volume. There is a level indicator as an added feature so you always know how much water remains in the tank after use. Adjusting the temperature is also easy with its LCD screen displaying the exact temperature of the water in the tank.

One concern in reviews mentioned that at a certain point, the boil button/feature seems to not function properly. This is disappointing since the boiler produces 21 cups of hot water due to its wide capacity. It can hold 5 liters of water inside the tank with an electrical power supply pull of 700W in the process.

What We Liked:
  • This boiler has great capacity.
  • The LCD indicator is very useful.
  • 5 different temperature settings
What We Didn't Like:
  • Metric labels only.
  • Issues with some temperature levels.

Customer Reviews

This product has a large volume capacity and is easy to check the tank water level thanks to its transparent diagonal lines. The smart LCD screen displays an accurate temperature and maintains the water temperature according to your thermostat settings. The dispenser is durable and can last up to 3 years.

What We Liked:
  • Ideal for small families.
  • Significant sleep mode.
  • Easy to clean.
  • Budget-friendly product.
What We Didn't Like:
  • Residue build-up issues.
  • Rust development issues on the lid.

Customer Reviews

Reviews suggest this product is the most efficient for on-demand hot water use and received a 4.2-star rating on Amazon by its customers.

The majority of these reviews were mostly positive experiences, but poor customer support experience has hurt the overall review. Customers reported that the Panasonic support department took no action after receiving warranty claims.

Like other models we reviewed, this product is also susceptible to rust and mineral build-up within the internal lining. This issue is typically noticeable around 3-4 months of use but can be prevented by regularly cleaning the unit.

The product can hold up to 3 liters and has a programmable cycle that can save on energy use. Overall, the dispenser is very handy and easy to fit in small spaces.

The Buyer’s Guide

instant hot water dispenser buyer guide

Features and Functions 

A hot water dispenser provides 94 degrees Celsius of nearly-boiled water. You can install it in two ways.

  • You can plumb it into the water supply of the house.
  • The dispenser heats either in an over-counter tank fixed to the wall or an under-sink tank.
  • It then dispenses hot water at the sink through a faucet.
  • They sometimes have built-in filters and thermostats to adjust the temperature when required.

Here are 8 features to look for in a hot water dispenser,

#1. Finishes

It’s always a great idea to buy a unit that matches the décor of the room it is placed. In this case, you might want to buy a dispenser with a faucet that matches your other sink features and finishes. Most water dispensers come with chrome faucets, but that can be a problem if your other kitchen hardware has a different finish. However, finding a dispenser that matches is usually easy since there are many different styles on the market.

#2. Temperature Control Settings

You should always look for a water dispenser with adjustable temperature settings. Some units come with constant hot temperatures, but that can be a downside in many cases. For example, brewing herbal tea is ideal only at specific temperatures. Also, the good thing is that units with adjustable water temperatures don’t cost much more.

#3. Wattage and Heating Time

Most hot water dispensers provide hot water instantly, however, sometimes this is not the case. That’s why you should understand wattage before you buy. For example, some models might take 5 seconds to heat the water, while some may need 30-40 seconds. Also, it doesn’t mean that the unit with more wattage is the best quality, only that it heats up water faster.

#4. Noise

Basically, every hot water dispenser makes some noise while working, but it shouldn’t be distracting. There are some styles that use loud beeping indicators when boiling is done, which may be distracting every time you make coffee or tea in the morning. Although it might not seem like a big deal now, it can become pretty annoying over time.

#5. Ease of Use

Most hot water dispensers are very user-friendly and simple to install. Once attached to a power source and filled with water, you just press the button and let it go to work. However, models that are connected directly to the sink faucet might be difficult to install. Be sure to consider this face, especially if you are not a DIY person. The tank of the unit should be easy to remove and wash, and also be easy to refill. Another useful feature to look for is a manual stop button.

#6. Tank Size

Mostly, hot water dispensers in the market come with a tank that has the capacity to contain half a gallon of water. This amount is enough to dispense as many as 60 cups of hot water on an hourly basis. These tanks have various options when it comes to sizes and frequently range between a third to three gallons.

#7. Power Source

A hot water dispenser gets power through the machine in it which runs on electricity. However, the supply of power is directly proportional to the amount of water that needs to heat. For instance, at a power supply of 750W, the hot water dispenser would be able to heat half a gallon of water.

#8. Taps

In hot water dispensers, the taps installed are specifically designed for boiling water. These dispense heated water instantly compared to using a kettle or pan on the stovetop. These boiling-water taps are a smart solution for streamlining kitchen surfaces.

You can have these taps plumbed beside your standard kitchen taps or wherever you decide to install the unit. Boiling-water taps can replace a conventional kettle or a plug-in hot water dispenser, but these take up more space in your kitchen.

Advantages and Disadvantages

Advantages
They operate in a simple manner just like a normal tap and provide you with precisely as much hot water as you may need. This feature adds to their efficiency
Manufacturers suggest that they are less expensive to run
These taps can be installed with childproof handles to avoid accidents
People with inabilities to lift, fill & pour a conventional kettle would find thIs tap easy to use
Some models of hot water taps come with pre-installed filters. They remove bad-tasting chemicals and softeners & aerators from the hot water supply
Disadvantages
Timely cleaning of the tap & tank may be of need to avoid limescale
Most of these models need their filters to be regularly replaced. This adds to the ongoing cost
In most cases, the upfront cost of instant hot water taps is high. It could take you a lifetime to recover your investment. So if you are on a budget then you should opt for an energy-saving kettle instead

Heat Adjustment Levels

When you initially install a hot water dispenser, the holding tank needs around 15 minutes to heat up. You set the thermostat to the temperature you want, but the water may cool a bit when it reaches the dispenser.

To make proper temperature adjustments, you must follow the steps below:

Step 1: Locate the dial of the thermostat. It should be present on the front of the tank.

Step 2: Turn the dial clockwise. Do it gradually to increase the temperature or anti-clockwise to decrease the temperature.

Step 3: If the water becomes too hot, you just twist the handle of the tank for over 15 seconds. This would allow cold water to enter and reheat to your desired temperature.

Step 4: You can continue adjusting the dial with minor increments. Keep adjusting the temperature until the water is hot enough for your preference.

Water Flow

There are numerous reasons that could affect the flow of these dispensers. Those reasons/causes stated below are followed by their solutions as well.

Clogged Faucet Aerator

  • Twist the aerator in an anti-clockwise direction to unscrew it.
  • Examine aerator
  • Keep flushing until cleansed

Water-Supply Valve Not Completely Opened or Plugged

  • Fully open the water supply valve.
  • Open the tightly closed saddle valve.
  • For models that have built-in filtration, check if the cartridge of the filter is properly installed. There is a chance that it needs to be replaced.

Circumvention In the Inlet of the Tank or Assembly of Faucet

  • Unlink the inlet fitting from the tank.
  • Place a tube on top of a bucket to gather water. Twist the handle on the hot side.
  • If the hot water flow side is weak, it means there must be a restriction in the faucet. In that case, the faucet would have to be replaced. If the flow is strong then there has to be a blockage in the inlet installation. In this case, you might need to replace the tank.

Bent or Tangled Tubes Under the Sink

  • Detach the aerator.
  • Check the flow of water through the faucet.
  • Examine and fix any bents or twisted/tangled tubes under the sink.

Filtration

Though it may be more sanitary, hot water requires filtration. Some chemicals used in water treatment may not disburse or be eradicated by mere heat, and there may still be harmful minerals, metals, and other contaminants. This affects the taste of water as well as its odor, so heating it may only intensify these effects.

Due to these factors, installing a water filtration system (inline) would ensure the purity, smell, and taste of water in a dispenser. This filtration can also be used for faucets that have both hot and cold water displacement.

Tank Material Used

Manufacturers are extremely careful in choosing the most compatible material to be used to make hot water tanks. The prime factor to consider while making this choice would be that a handsome amount of heat would be involved in this setup. Therefore, the most reliable material in this scenario is stainless steel.

Stainless steel has proved to be long-lasting as compared to rubber bladder which is also used by some manufacturers to produce hot-water tanks. Although rubber bladder tanks are cheaper than stainless-steel ones, they can wear out within the first year of purchase.

Additional Features

Here are 4 additional features to look at when purchasing a hot water dispenser.

1. Self-Closing Valve

A self-closing valve is usually made of high-impact resistant brass with a chrome finish. This helps in resisting corrosion and also provides extra strength and durability. A self-closing valve consists of a half-inch iron pipe size inlet and outlet in-line straight connections. This self-closing valve has a single metal handle to control the flow of the water easily.

2. Drip Tray

Drip Trays are essential for dispensers since they allow the filling of jugs, bottles, cups, and other vessels to be achieved safely and easily.

There are two specific brands that offer drip trays dedicated to hot water taps/dispensers: Zip and Billi. Both of these manufacturers provide pre-installed tubes so that drainage can go straight towards the under sink waste line. They both also offer a tank waste feature located away from the sink if required.

Besides other useful features, Zip offers drip trays that are not dedicated or linked in any way, which can be used for units from other brands that do not come with drip trays of their own.

3. Energy Efficiency

The hot water dispensers that keep heated water in a tank only use the energy that is needed to achieve the desired temperature. This attempt, in turn, wastes the energy that is needed to keep that very same quantity permanently hot.

As these tanks are thermally insulated, the water does not seem to stay as hot as it should be if it is not used. An instant heater that does not have a tank, does not waste this essential energy. So, dispensers that are tankless are more energy-efficient than the ones with tanks.

4. Indicator Light

Also known as a Heating Indicator Light, this feature comes in handy when you are trying to keep track of the machine’s water heating cycle. The indicator light will turn on when it is in the heating process until it reaches 185°F. Once the hot water dispenses, the hot tank would refill and the heating indicator light will turn on as it starts to heat again.

Types of Dispensers

There are three main types of water dispensers. Let’s check them out.

1. Bottom or Top Loading

These are probably the most widely used dispensers. Typically, these come with a tank placed on top of the unit, but rarely it could be on the bottom.

2. Point-of-Use or Bottle-less

These dispensers are usually connected directly to a waterline and get directly placed within a wall, which often requires a professional installation. Even if you are a DIY person, you might still want to hire a professional plumber.

3. Portable

These devices are usually small but should provide you with enough water for the day. Also, they require no special installation and can be simply put on the counter.

Quick Buyers Tips

Personal Needs

At first, think about whether you use lots of hot water during the day. For example, if you constantly drink coffee, you will need a unit with more capacity. The type of dispenser you buy choice primarily depends on your daily water usage.

Right Technology

A hot water dispenser can sometimes be tricky to install, but once completed, it will provide you with hot water anytime you wish. You could always go with a tabletop unit that takes a bit more time to heat the water, but it’s usually not too long.

Durability

Some units might cost you a bit more, so make sure that it lasts longer than a couple of months. Paying a bit more for a higher quality model is a good long-term investment.

Cleaning and Maintenance: Few Tips

Cleaning a dispenser is actually pretty simple. At first, make sure that you start cleaning from the outside. You should do it with a wet cloth. However, if it’s too dirty, you can use a little bit of dishwashing liquid. Rinse the cloth and wipe the whole unit again being sure to remove the remaining water with a dry towel or a piece of cloth.

When cleaning the reservoir, make sure that it’s unplugged, and if it uses a bottle, set that aside. Fill the reservoir with dishwashing liquid and water, and clean it properly. Then, rinse it with water again and dry with a cloth.

Faucet Unit vs. Countertop Unit

These dispensers are a great solution for every household these days. The demand for convenient and innovative hot water supply has increased remarkably. Thanks to this market being highly competitive, a wide variety of hot water dispensers has been introduced in the market.

Faucet Unit

This model is plumbed directly into the main supply and heats the water in either an under-sink or over-counter tank which is fixed to a wall. These mostly tend to have filtration systems built in them as well as a thermostat to make temperature adjustments quickly and easily.

These dispensers have the ability to produce large quantities of heated water at once at a temperature you specify. Products in this category are not overly wallet-friendly and often require professional plumbing services. They also waste electrical energy to keep all the contained water hot constantly.

Countertop Unit

These are smaller units that can be placed on the counter/table directly. They do not require plumbing work as they are tankless heaters and dispense hot water instantaneously in a hassle-free manner.

Setup and Install

Faucet Installation

These dispensers require significant plumbing and electrical adjustment that may require you to hire a pro. But, if you would like to make this into a DIY project, then you may follow this link for a step-by-step guide on how to do it yourself.

Countertop Installation

These dispensers do not require much work or effort to install and set up. You likely won’t need a professional to do this for you as the installation is a minimal DIY project. You may follow this link on a step-by-step guide on how to do so.

Quickly Make Hot Water

Instant hot water dispensers that do not have a water tank, do not waste energy. With just 2000W of electrical energy at the time of consumption, these instant hot water dispensers produce ready hot water at 20 liters per hour frequency.

In comparison to this, the best dispenser with a water tank consumes about 500W of electrical energy to produce the same amount of hot water but in less than half of the time that the instant hot water dispensers consume.

Therefore, a comparison in th efficiency can be estimated only by calculating energy that the water heater has wasted. It can be compared with the electrical energy that provides a means to heat more quantity than needed in a kettle or another similar vessel.

Frequently Asked Questions

Are Hot Water Dispensers Dangerous?

Basically, these dispensers are not dangerous appliances. They can only be a risk if you have young children around them since they could accidentally burn themselves with the hot water. It’s recommended to buy a unit with child-lock safety to prevent this from happening.

How Much Water Will I Use Daily?
