Product Reviews

Now that you know a little more about the different types of hot water dispensers, it’s time for reviews of some of the top-rated models available today. We spent a long time reading user feedback and professional opinions to bring you our top seven hot water dispenser reviews.

1. Tiger Corporation Tiger PDU-A40U-K Electric Water Heater

Best Hot Water Dispenser for Small Spaces

A compact countertop unit that still packs a punch, this model features a built-in temperature control. It offers both keep-warm and reboil options to provide water at your specified temperature. Two standout features are its energy-saving timer and de-chlorinate function to remove unwanted chlorine and odors from the water.

The water tank has a capacity of 4 liters. The water gauge has an auto-off feature that activates when the level is too low.

What We Like

Space-Saving

A countertop model will occupy part of your work surface. Still, at about a foot tall, this model will provide you with convenient hot water while taking up a relatively small space.

Extra Features

This model offers several extras, including a large, integrated display panel and an automatic locking system when it has not been operated for 10 seconds.

You have total control over the water dispenser via its top control panel. Its simple buttons are easy to operate and allow you to adjust the temperature and initiate de-chlorination.

Exceptional Design

Special care has been given to this unit’s construction. The interior stainless steel cavity is O-shaped, creating a low center of gravity. This helps prevent accidental tipping of the inner tank and the entire unit, which avoids burns during use.

The water flows quickly and, when the unit detects no user input for 10 seconds, it automatically locks to prevent burns and spills. This attention to detail extends to the exterior of the dispenser.

What We Don't Like

It’s Petite

This unit’s small size will help you save space, but it also reduces the amount of water it can hold. You will need to frequently refill it, especially if multiple people use it.

If you anticipate your dispenser being used frequently, you might want to consider a different model.

Product Specs

Dimensions 12 inches by 9.1 inches by 11.4 inches
Weight 3.31 pounds
Type Countertop
Material Stainless steel
Additional Features De-chlorination; temp control; auto-lock

2. Zojirushi Panorama Window Micom Water Boiler and Warmer

Best Safety Features

This unit features a clear window that will allow you to keep a close eye on the current water level. It is also equipped with an easy-to-use control panel with an LCD display.

Four different heat settings help you achieve the ideal water temperature for drinking and cooking. A cafe-drip feature slows the water output by 60%, making this unit suitable for making coffee.

The unit’s interior is easy to clean, and its small size means you won’t need to sacrifice much counter space.

What We Like

Panoramic Window

A plastic viewing window is the height of the internal water chamber. This allows you to see how much water is inside the unit at a glance.

This is particularly useful if your dispenser sits below something else and needs to be moved when you want to open the top and look inside.

Multiple Modes

While some models offer only basic options for heated water, this one has four distinct heat modes. You can choose the specific level of heat you want, from a gentle rewarming to an intense boiling.

In addition to the temperature control, you can also select how much water you want, from a slow drip to a fast flow.

Magnetic Power Cord

This unit has some excellent safety features. Its magnetic power cord detaches easily, preventing it from being pulled off your counter if something tugs on the cable. It also has an energy-saving timer that helps to reduce its electrical use.

What We Don't Like

Made of Multiple Materials

While the bulk of the internal structure is made of stainless steel, other metals are also used. These can be prone to rust, which means you might need to empty the chamber between use to prolong its lifespan.

Product Specs

Dimensions 11.9 inches by 9.1 inches by 10 inches
Weight 6 pounds
Type Countertop
Material Stainless steel; metal; plastic
Additional Features Magnetic power cord; panorama window; LCD control panel

3. InSinkErator Instant Hot Water Dispenser

Best Installed Set

This compact installed option features a temperature dial located on its tank. In addition to the unit’s heating element, it includes a deck-mounted chrome faucet.

As this instant hot water dispenser is designed to be built-in, it will need to be installed through your countertop, much like a kitchen faucet.

This model’s tank can hold up to two-thirds of a gallon of hot water and it is suitable for both home and commercial use.

What We Like

Streamlined Look

If you want style, nothing beats the clean look of a built-in water dispenser. The dedicated faucet is unobtrusive and compatible with various kitchen styles, providing user-friendly control over your hot water.

Small Size

This is an excellent option if you’re looking for an installed model that won’t occupy much cabinet space. Despite its small size, it is still capable of holding an impressive amount of water.

Can Be Used with a Filter

As it can be connected to a water filter, this dispenser is a great option if you don’t feel your water supply is clean enough to drink normally.

InSinkErator offers both hot and cold water filters designed to work alongside their dispensers. They can be purchased separately when required.

What We Don't Like

Might Need Help

Even if you feel confident tackling the plumbing part of this installation by yourself, you might still need to call in an electrician.

This unit will require a dedicated outlet within your sink cabinet. Its proximity to your water source means special care needs to be taken during the installation process.

Product Specs

Dimensions 6 inches by 7.75 inches by 11 inches
Weight 7.4 pounds
Type Built-in
Material Stainless steel
Additional Features Faucet included; temperature control dial; power cord

4. Bosch Electric Mini-Tank Water Heater

Best for High-Volume Water Needs

This water heater from Bosch is available in multiple sizes, making it an excellent option for commercial or shared spaces. The smallest tank size is 2.5 gallons, while the largest is an impressive 7 gallons. Unsurprisingly, the larger the tank you choose, the more under-sink space you will need.

Like other hot water dispensers, you will need a dedicated outlet to use this unit. Requiring low maintenance and with a fast recovery rate, this product boasts 98% thermal efficiency.

What We Like

Glass-Lined

Most other units have a metal-lined interior, which can suffer rust and leaks. This model is designed for longevity and uses high-quality glass on the interior to provide a low-maintenance heater.

Multiple Mounting Options

Designed to be versatile, this heater can be installed under a counter or on top of it to suit your needs. The largest model can even be installed sideways to fit your space.

A mounting bracket is included to make installation as quick and easy as possible and ensure it is completed properly.

Exceptional Capacity

With a 2.5-gallon capacity, even the smallest tank option can hold a substantial amount of water. The larger models can be used to supply multiple sinks or to provide hot water to showers and baths.

At a compact size, it is even a good option for a primary heater in a boat or RV.

What We Don't Like

Double-Check the Pressure Relief Valve

This heater is equipped with a pressure relief valve. If you notice water on or near your heater, double-check the valve and make sure it is correctly positioned. If it isn’t, condensation can form on the outside of the heater.

Product Specs

Dimensions 13.75 inches by 13.75 inches by 10.75 inches
Weight 15.5 pounds
Type Built-in
Material Glass; plastic; metal
Additional Features Included mounting bracket; included cord; temperature dial

5. Avalon Full-Sized Self-Cleaning Water Dispenser

Best for Water Filters

With a streamlined, attractive appearance, this full-sized model will look great in your home or office.

A large internal cavity can house two filters — one for sediment and another for microscopic impurities. This makes it an excellent option for locations that have questionable water sources.

This model doesn’t use bottled water, so it will need to be connected to your existing plumbing. Using your water supply will reduce the ongoing costs and cut down on maintenance.

What We Like

It’s Versatile

This unit will be connected directly to your water supply, which means it will receive water indefinitely.

With three different temperature settings — icy-cold, cool, and piping hot — it is a versatile option that will fulfill all your beverage needs.

Self-Cleaning

Not having a bottle reduces the need for maintenance, as does this model’s self-cleaning feature. When the time comes, simply press the self-clean button and your unit will clean and sterilize itself. You will be able to enjoy fresh-tasting water with minimal effort.

Very Safe

If you have children in your home, you might be concerned about adding a hot water dispenser. This model features a child-safety feature on the hot water outlet that will help protect vulnerable people.

Its installation style also makes tipping very unlikely, while a blue nightlight lets you use it safely — even in the dark.

What We Don't Like

The Manual Could Be Better

Although there are photos included in the installation manual, they can be difficult to follow. If your dispenser is incorrectly installed, you may encounter leaks. If you aren’t confident that you can install it properly, it is usually best to hire a professional.

Product Specs

Dimensions 13 inches by 12 inches by 41 inches
Weight 44 pounds
Type Full-sized
Material Metal; plastic
Additional Features Self-cleaning; no bottle

6. Avalon Countertop Top-Loading Water Dispenser

Best Countertop Bottled Water Dispenser

If you want the convenience of a top-loading unit and the smaller size of a countertop model, consider this Avalon dispenser. Its attractive exterior and clearly-labeled hot and cold outlets are ideal for both home and commercial spaces.

As it fits a standard water bottle mouth, you can choose the bottle size that works best for you. There are two temperature settings that let you choose from cold and piping hot water, depending on why you need it.

What We Like

Child Safety Lock

This model offers two heating modes: cool and hot. To prevent children from accidentally scalding themselves with hot water, that setting is equipped with a safety lock.

Great for Any Location

There is no need to connect this model to your plumbing, so you won’t have to rely on your usual water source. You can buy the treated water of your choice and use this dispenser almost anywhere. All you need is access to a source of electricity.

Attractive Design

With a sleek, modern design, this dispenser will combine well with a variety of styles and decor.

The plastic front of the dispenser body is available in two color choices — black or white — to best match your room’s style.

What We Don't Like

Required Space

Although the dispenser itself isn’t oversized, you will also need to account for the height of the water bottle. These bottles are available in different sizes but they are unlikely to fit under a wall-mounted cabinet. If you don’t have a countertop with the necessary clearance above it, you will need something else to support this dispenser.

Bottled Water Costs Extra

Being able to choose the specific water you drink is beneficial, but we can’t ignore the extra cost of bottled water. Depending on how much water you drink, you could empty bottles quickly, which can make a bottled water dispenser a costly addition to your property.

Product Specs

Dimensions 13 inches by 12 inches by 19 inches
Weight 30 pounds
Type Countertop
Material Plastic; metal
Additional Features Child safety lock

7. Ready Hot Stainless Steel Hot Water Dispenser

Best Hot Water Dispenser for Cooking

An external dial on the tank allows you to easily control the water temperature of this heater, and it is capable of producing 190-degree water. The tank can hold 2.5 gallons of water and the unit is capable of providing 60 cups of hot water per hour.

A dedicated faucet is included with this built-in unit. It is tall and elegant, meaning it is ideal for filling pots and other cooking implements.

You can choose from a chrome or brushed nickel finish to ensure it looks right at home in your kitchen.

What We Like

Automated Heater Protection

This heater is equipped with automated protection to prevent your heater from accidentally burning out. In the event that the tank is emptied (due to an open tap or loss of water), the heater won’t be damaged by overheating.

Attractive Faucet

The traditional, attractive faucet provides the clearance necessary to fill large pots with hot water. It is available in multiple finishes to create the look you want in your kitchen. Sleek and unobtrusive, it won’t call attention to itself once installed.

Built-In Safety Feature

With two handles on the faucet, the hot tap needs to be pressed firmly to operate it. This safety feature is designed to prevent children from operating the the handle and accidentally burning themselves.

What We Don't Like

Faucet Has a Narrow Arch

If you choose to use the included faucet, you will need to install it near the edge of your counter. Although the faucet is tall and has a gooseneck, it doesn’t reach far forward. If it is installed improperly, the stream of water will hit the countertop instead of the sink. This also increases the likelihood of back-splashing, which can cause burns.

Product Specs

Dimensions 11 inches by 8 inches by 12 inches
Weight 14.05 pounds
Type Built-in
Material Stainless steel; brushed nickel
Additional Features Faucet included

Types of Hot Water Dispensers

Before you start shopping, you should familiarize yourself with the different types of dispensers that are available. The space you are working with and your personal requirements will influence which style is right for you.

One of the most important considerations is whether you are choosing a dispenser for a private residence or a commercial space.

Built-In Hot Water Dispensers

Built-in hot water dispensing units are connected directly to your plumbing. A separate tank keeps water at a specified temperature. When you turn on the tap, you will receive a stream of water that is the ideal temperature for hot drinks.

When installing a new kitchen, it’s easy to incorporate one of these models into your design. If you are installing it into an existing kitchen, however, it may require some extra time and money.

Built-in hot water dispensers feature a separate tank that is usually mounted inside the sink cabinet, so look carefully at the measurements. If you have limited space or other large under-sink items such as a water filter, you might be unable to fit a built-in water dispenser.

In addition to the space under your sink, you will also need to accommodate a new hose for a dedicated tap. This faucet is usually placed next to your primary kitchen faucet. You might need to drill a hole in your countertop to complete the installation, so you may want to hire a professional.

While these systems are very efficient and require little maintenance, the installation cost is generally greater than other options. If an under-sink hot water dispenser doesn’t include a dedicated faucet, you will need to purchase one separately. If you decide on professional installation, you will also need to factor that into your costs.

Pros

  • Resource-efficient
  • Low-maintenance, with no tank
  • Streamlined, incorporated look

Cons

  • Complicated installation
  • Higher initial costs

Countertop Hot Water Dispensers

As the name suggests, a countertop hot water dispenser sits on your work surface. As they are always visible, they tend to have more attractive designs than concealed units.

You will need to refill the water basin for continuous hot water. This won’t be difficult, as most countertop dispensers are designed to plug directly into an outlet.

They are convenient because they will work anywhere and can be taken with you if you need hot water. However, they are also frequently designed with a smaller tank and work best in a home environment.

These units require a surface to sit on, so if countertop space is limited or you have low wall cabinets, they might not be suitable. Under these circumstances, a built-in water dispenser may serve you better.

If you anticipate needing a large volume of hot water, consider choosing a full-sized unit instead.

Pros

  • Generally affordable
  • Greater focus on visual appeal
  • Will work anywhere with an outlet

Cons

  • Occupies counter space
  • Small tank capacity

Full-Sized Hot Water Dispensers

A full-sized hot water dispenser combines the convenience of a countertop unit with the high capacity of an installed model. They provide an excellent option for commercial spaces and work well in residences where the water supply is of inferior quality. Rather than using water from your water supply, you can bring pre-treated or purified water into your home.

Like a countertop model, you will be responsible for keeping this unit filled with water. However, while most countertop models have a small capacity, full-sized dispensers are intended to be used with large refillable or recyclable water tanks.

Most full-size models feature both hot and cold options, which makes them versatile units. Like countertop dispensers, they are usually powered by an electrical outlet.

Pros

  • Ensures water quality
  • Large capacity
  • For commercial or residential use

Cons

  • Requires frequent maintenance, such as replacing the water tank
  • Occupies a relatively large space

What to Look For

To help you find the best hot water dispenser for your needs, take some time to consider the following before you start shopping.

Intended location

Think about where you will place your hot water dispenser. Each type of dispenser poses its own space challenges, so measure carefully to ensure your chosen unit will fit where you want it to go.

Water usage

If you regularly use a lot of hot water, you should choose a high-capacity unit. If you only use hot water occasionally, you should be able to get by with a smaller one.

Installation requirements

Think carefully about whether or not you would be comfortable installing a hot water dispenser yourself. If you wouldn’t, you will probably need to hire a professional and should factor this extra cost into your overall budget (1).

Maintenance level

Decide whether you are happy to regularly replace the water bottle in your hot water dispenser, or you want a unit that you can install and forget about until you need to clean it. The amount of maintenance that each dispenser needs will vary, but all types require at least some attention (2).

Budget

You can find every type of hot water dispenser at a wide range of price points. Determine how much money you are willing (and able) to spend before you start shopping.

Consider The Big Picture

Don’t just look at the cost of a unit when shopping. Include the ongoing costs of water and electricity to have a fuller understanding of whether or not a unit is suitable for your budget. Don’t forget to add any professional installation and extra supplies to your total cost.

FAQs

Are Water Dispensers Worth It?

Water dispensers are worth it to enjoy fresh and clean drinking water. The water dispenser allows customers to select their preferred water temperature, ranging from cold to moderate to hot.

This eliminates the need for users at home to boil water and then wait for it to cool down. Instantaneously available at the dispenser is hot water that has been boiled, which you can use to prepare other beverages.

Does a Water Cooler Purify Water?

Water coolers do not purify water. However, since you decide what water to add to the cooler, you can choose filtered or bottled water that’s already safe to drink.

What Is the Difference Between a Water Cooler and Water Dispenser?

The water dispensed from a water cooler by a water cooler is cooled before being dispensed. Still, the water dispensed from a water dispenser is simply at room temperature.

Both will give you a clean and fresh taste, but each will be served at a different temperature. A water cooler gives you rapid access to cold water.

How Much Does a Water Cooler Cost Per Month?

For each installed unit, a water cooler will run anywhere from $30 to $50 a month. This price is determined by the amount of water you anticipate consuming and the model you purchase from the provider.

Which Water Cooler Is Best for Home?

The Brio Top Loading Water Cooler is one of the best products for your home.

This Brio water cooler features a top-loading design and an easy-to-use system, making it suitable for home and workplace use. It has contemporary housing made of stainless steel, which complements other stainless kitchen appliances and dispenses water at various temperatures.

How Often Should You Change a Water Dispenser?

You don’t change the water dispenser but must replace its filters once every six to eight months. The frequency depends on how much you use it.

For instance, if the water cooler is installed in a high-traffic place (like a business building), the proprietor of the business should replace the filter every six months.

A new filter guarantees that the water continues to have a high level of quality. A household of two can go by with annual filter replacement.
