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
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.
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.
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
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.
|Dimensions||12 inches by 9.1 inches by 11.4 inches|
|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
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.
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.
|Dimensions||11.9 inches by 9.1 inches by 10 inches|
|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
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.
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.
|Dimensions||6 inches by 7.75 inches by 11 inches|
|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
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.
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.
|Dimensions||13.75 inches by 13.75 inches by 10.75 inches|
|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
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.
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.
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.
|Dimensions||13 inches by 12 inches by 41 inches|
|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.
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
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.
|Dimensions||13 inches by 12 inches by 19 inches|
|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.
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.
|Dimensions||11 inches by 8 inches by 12 inches|
|Material||Stainless steel; brushed nickel|
|Additional Features||Faucet included|
|Tiger Electric Water Boiler||For Small Spaces||12″ x 9.1″ x 11.4″||3.31 lbs||Countertop||Stainless steel|

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.
- Low-maintenance, with no tank
- Streamlined, incorporated look
- 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.
- Generally affordable
- Greater focus on visual appeal
- Will work anywhere with an outlet
- 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.
- Ensures water quality
- Large capacity
- For commercial or residential use
- Requires frequent maintenance, such as replacing the water tank
- Occupies a relatively large space
