The InSinkErator H-Wave-SN is a hot water dispenser that delivers hot water on demand. Despite its intimidating name, it's not a threat to life on Earth. Instead, it's a top choice for those in need of hot water at their fingertips.

InSinkErator H-Wave-SN
Feature Specifications
Type Tank Type
Power Source Electricity
Dimensions 6.75 x 6.12 x 10.87 inches
Temperature Range 160°F – 210°F
Capacity 2/3 Gallon
Voltage 115V
Warranty 3-Year

The InSinkErator H-Wave-SN offers a balance between under-sink hot water and easy installation. Its ⅔ gallon capacity allows you to serve multiple guests with hot beverages or fill a pan for spaghetti. It's also an affordable option, with a included faucet and a tank that won't break the bank. The H-Wave-SN comes with a one-year warranty.

The InSinkErator H-Wave-SN has a matte black finish and comes with a stainless steel faucet. However, its traditional curved design may not match modern fittings. The H-Wave-SN is made with quality materials, including a BPA-free tank and corrosion-resistant piping.

To use the H-Wave-SN, you'll need to plug it into an AC outlet and manually refill the tank. The faucet must be installed on your countertop, but there's no plumbing required. Keep in mind that the faucet has a pipe depth of 2″, so it won't fit on countertops thicker than this.

The H-Wave-SN has a 60-cup per hour flow rate and a thermostat that allows you to adjust the temperature, with a maximum of 210°F. However, the thermostat is located under the sink, which can be inconvenient to access. The faucet handle is spring-loaded, requiring you to hold it to dispense hot water. Once released, it will shut off automatically for safety.

Bottom Line The InSinkErator H-Wave-SN is an affordable instant hot water dispenser that is easy to install. It may be the only one you will ever need to purchase. View Latest Price on Amazon →

2. InSinkErator F-H3300C – Best Hot Water Faucet

We love InSinkErator's Hot150 water tank, so we're checking out some of their other options. The F-H3300C is their flagship faucet, a sleek unit for hot water on tap.

InSinkErator F-H3300C
Feature Specifications
Faucet material Brass with chrome finish
Temperature control Handle controls temperature
Swiveling spout 360 degree
Compatibility Requires separate water tank
Price $$$

The InSinkErator F-H3300C is a top-tier instant hot water dispenser with a powerful flow rate thanks to its wider base. It doesn't come cheap, however – this is a high-end unit for those who can afford it. It's important to note that the price mentioned is only for the faucet, not the water tank.

The faucet itself is built from hard-wearing brass with a chrome finish, making it a modern and durable choice for contemporary kitchens. The moving parts of the faucet swivel smoothly, and it has a spring-loaded safety feature that prevents the faucet from running without the user.

However, it's important to note that this is a faucet-only unit and requires a separate water tank to function. If you already have an InSinkErator F-H3300C hot water tank, installation should be straightforward. If you have a different brand of water tank, you may need to visit a home improvement store to find the right valve.

The handle on the InSinkErator F-H3300C controls temperature, and the 360-degree swiveling spout can be turned in any direction for easy pouring. The controls for this faucet may take some getting used to, but the spring-loaded safety feature can be overridden on the cold-tap setting, making it a versatile choice for your home.

Bottom Line The InSinkErator F-H3300C hot water dispensing faucet is a high-quality option that won't disappoint. While the price may be higher, the faucet comes with a 5-year warranty, giving you confidence in your purchase. View Latest Price on Amazon →

Zojirushi has reinvented the kettle to give you instant access to hot water on your countertop. However, the cost of the Zojirushi 586361-CV-DCC40XT is closer to that of under-sink dispensers than kettles.

Zojirushi 586361-CV-DCC40XT
Feature Specifications
Model Zojirushi 586361-CV-DCC40XT
Type Hybrid Water Boiler and Warmer
Location Countertop
Capacity 1 gallon
Boiling Time 25 minutes
Filling Manual carrying to sink
Weight 15 lbs when full

The Zojirushi 586361-CV-DCC40XT Hybrid Water Boiler and Warmer is a countertop unit that sits beside your toaster.

The inner tank is made of non-stick stainless steel, and the outer chassis is made of BPA-free plastic. The unit comes with a one-year warranty.

To use the Zojirushi 586361-CV-DCC40XT, simply fill it through the lid on top and plug it into an AC outlet. Some set-up is required, however, including rinsing the inner chamber before use and allowing it to bring the water up to the desired temperature. With a full gallon of capacity, it takes about 25 minutes to bring the water to a boil.

The Zojirushi 586361-CV-DCC40XT has a range of features, including Regular and Quick Temp modes for heating water, options for timing the boiling point, and an automatic shut-off feature.

4. Ready Hot 41-RH-300-F570 – Best Low Maintenance Model

The Ready Hot 41-RH-300-F570 is an under-sink instant hot water dispenser that's reliable and equipped with high-tech features that require minimal maintenance. It provides hot water on demand.

Ready Hot 41-RH-200-F560
Feature Specifications
Type Under-sink
Design Industrial
Thermostat Only low and high settings
Faucet availability Optional, can be connected to any open-vented faucet
Capacity sensor Prevents overheating when tank is empty
Noise level Noisy when heating water
Installation Requires plumbing into home's water supply

As an under-sink model, the Ready Hot 41-RH-200-F560 is not something you'll see every day. Its industrial design is better suited to a commercial setting than a stylish home, but at least it's hidden under the sink.

Unfortunately, the Ready Hot 41-RH-300-F570's thermostat only has low and high settings, so there is no way to pinpoint the temperature of the water. This means you don't have the fine-tuned control that other units offer.

The Ready Hot 41-RH-300-F570 is available with or without a faucet from the company, giving you control over your kitchen setup. If you choose to buy just the heater unit, it can be connected to any open-vented faucet.

This instant hot water dispenser needs to be installed by plumbing it into your home's water supply and connecting it to a faucet on your countertop. It also needs to be plugged into an AC outlet, but with 1300 watts of power, it should be grounded to protect against power surges. If you're not comfortable with electrical and plumbing work, it's best to hire a professional for the installation.

Once it's set up, the Ready Hot 41-RH-200-F560 has a capacity sensor to prevent overheating when the tank is empty, and its durable components should not degrade.

However, when the Ready Hot 41-RH-300-F570 is heating water, it can be a little noisy – but that's a small price to pay for instant access to hot water.

Bottom Line The Ready Hot 41-RH-300-F570 hot water dispenser is easy to use and requires no maintenance once it's installed. However, the dial-style thermostat and the noise of the unit are drawbacks. View Latest Price on Amazon →

5. Anaheim AH-1300 – Best On A Budget

The Anaheim AH-1300 is an affordable option for those in need of an instant hot water dispenser. It offers a one-year warranty and reliable performance. Its build quality ensures that it will provide hot water for your home without breaking the bank.

Anaheim AH-1300
Feature Specifications
Capacity 60 cups of hot water per hour
Maximum temperature 190°F
Build quality Stainless steel
Insulation feature Keeps water warmer for longer
Faucet Not included
Tank size 5/8ths of a gallon
Power 1300 watts

The Anaheim AH-1300 is a chic design model that will fit in well with contemporary kitchen appliances. It's made of stainless steel, BPA-free plastic, and rust-resistant materials, making it a sturdy unit that should have a long lifespan. The insulation feature is a great added bonus, as it keeps the water warmer for longer when not in use, resulting in faster reheating and lower energy bills. However, please note that the Anaheim AH-1300 does not come with an accompanying faucet. You can install the unit yourself if you're confident working with pipes.

With 1300 watts of power, the Anaheim AH-1300 heats water quickly. Its 5/8ths of a gallon tank can provide around 60 cups of hot water per hour. However, you may notice that the water becomes a little lukewarm towards the end of the pour when boiling pasta for the whole family. Additionally, the temperature of the water only reaches a maximum of around 190°F. This may affect your overall satisfaction with the Anaheim AH-1300.

Bottom Line The Anaheim AH-1300 is a budget-friendly option worth considering. It's one of the cheaper models available, but also has added insulation to help reduce energy bills. View Latest Price on Amazon →

8. Chefman Electric Hot Water Pot – Best For Hot Water Capacity

The Chefman Electric Hot Water Pot offers a large capacity at a reasonable price. With a capacity of almost 1.5 gallons, it's one of the largest hot water dispensers on the market for home use. It would also be well-suited for an office break room.

Chefman Electric Hot Water Pot
Feature Specifications
Capacity Almost 1.5 gallons
Dimensions Tall and stylish
Hot water settings Only one setting
Insulated chamber Yes
Reboil option Yes
Swiveling base Fully 360°

The Chefman Electric Hot Water Pot is a tall and stylish hot water dispenser that will fit in any modern kitchen. It has an extra-wide top-loading lid and a carry handle, as it can weigh up to almost 20 lbs when filled. The unit also has a fully 360° swiveling base, which makes it easy to dispense water in any setting. However, this feature may not be convenient on a countertop. It's easy to install – just fill it up and let it boil. The power cord is 48″ long, allowing you to plug it into even hard-to-reach outlets.

Water is dispensed from the spout at the top of the Chefman Electric Hot Water Pot. There is space around the spout to fit bowls and pans for cooking purposes, but the height of the unit means that hot water travels a distance before reaching your cup, increasing the risk of a splash.

This hot water dispenser has only one hot water setting and no timer options, but it has an insulated chamber and a reboil option to ensure you don't have to wait long for hot water. The main focus of the Chefman Electric Hot Water Pot is providing a lot of hot water.

Bottom Line Chefman has created a hot water dispenser with a large capacity and a low price, making it suitable for both offices and families. However, it lacks additional features that could enhance its functionality. View Latest Price on Amazon →

The Ultimate Guide to Choosing the Best Instant Hot Water Dispenser

Before we discuss the key factors to consider when choosing an instant hot water dispenser, let's first define what these appliances are and explore the different types available.

What's an Instant Hot Water Dispenser?

An instant hot water dispenser is a small appliance that heats and dispenses hot water on demand. It's typically installed under a kitchen sink and connects to the home's water supply, allowing users to quickly and easily access hot water for a variety of purposes such as making tea, coffee, or instant soup. These appliances can be a convenient and energy-efficient alternative to boiling water on the stove or using a traditional electric kettle.

Under-Sink Hot Water Dispenser vs. Countertop Hot Water Dispenser

There are two main types of instant hot water dispensers: under-sink and countertop. Both provide hot water on demand, but their installation and hot water access differ.

Under-Sink

Under-sink hot water dispensers are installed under the kitchen sink and can be plumbed in or have a manual-fill tank. They are attached to a faucet above the sink, allowing for instant access to hot water. However, installation can be more involved and may require drilling holes in the countertop and calling a plumber.

Countertop

Countertop hot water dispensers are more similar to traditional kitchen appliances like toasters and kettles. They don't require installation and are manually filled with water, which is then dispensed through a spout into mugs or pans. While these appliances don't offer the convenience of hot water on tap, they do not require installation.

Key Factors to Consider Before Choosing The Right Instant Hot Water Dispensers

Whether you’re gunning for a super-slick under-sink model or a countertop hot water dispenser, here’s everything you should consider before making your purchase.

Maintainance

Proper maintenance is important to extend the lifespan of your instant hot water dispenser and get the most value for your investment. Consider choosing a model with self-cleaning functions and built-in filtration to minimize maintenance requirements.

Depending on the quality of your water supply, you may need to descale the unit every few months by adding bicarbonate of soda to the tank and flushing a few full tanks of water through the unit to remove residue.

Power Consumption

Power consumption is an important factor to consider when choosing an instant hot water dispenser. These appliances have a wide range of wattage and temperature options, which can impact their energy usage.

Opting for a model with lower wattage may result in lower energy consumption, but it may also compromise on speed and temperature. It's important to find a balance and choose a model that meets your needs without going above and beyond.

Capacity 

Under-sink models typically have larger tanks, making them suitable for families that consume a lot of hot water. Countertop models come in a range of capacities, from large to small, to fit different needs and kitchen spaces.

Temperature Control

Some instant hot water dispensers have electronic displays that allow you to program the water to a specific temperature. Others have a dial that allows you to adjust the temperature. Consider the temperature control options available when choosing a model.

For some people, hot means hot, but for others, the difference between 202°F and 208°F can make or break a brew.

Filtration and Purification

To ensure the water you drink is clean and pure, it's important to consider filtration and purification when choosing a hot water dispenser. Some models are equipped with charcoal lining or high-quality water filters for added protection. Boiling water can also kill bacteria, but for extra peace of mind, a purification feature can be valuable.

Flow Rate

If you're considering purchasing an instant hot water dispenser, chances are you value efficiency and convenience in the kitchen. You want hot water quickly, and waiting for the pasta pot to fill is not an option. Therefore, it's important to consider the water flow rate of the unit, which can be influenced by both the wattage of the unit and the faucet (whether it is included or purchased separately). To ensure fast hot water delivery, look for a high-powered product paired with a wide-based faucet.

Efficiency  

Efficiency is an important factor to consider when choosing an instant hot water dispenser. Under-sink models are highly efficient because they only heat the water once and keep it insulated at the required temperature until it's used.

However, if you only need hot water for occasional cups of tea, a countertop model may be more energy-efficient because it allows you to fill up as needed rather than heating a tank unnecessarily. It's important to consider how you will use the dispenser and choose a model that is efficient for your needs.

Appearance

An under-sink hot water dispenser has a sleek, modern appearance that fits seamlessly into your kitchen design. These units boil water straight from the faucet and are a great choice for those who prefer a minimalist look.

Countertop hot water dispensers can also be stylish and modern, but if you prefer a clean, streamlined look, an under-sink unit may be the better choice.

Time Saver

Installing a hot water faucet allows you to access boiling water on demand, saving you time. With this type of appliance, you can quickly make a cup of tea or start boiling pasta.

Some countertop models have preprogramming functions that allow you to set them up in advance, but they may still require an additional step compared to a built-in model.

Accessibility 

Under-sink hot water dispensers are stationary, with the hot water being dispensed from the faucet. This means you have to go to the sink to access the hot water. On the other hand, countertop units are portable and can be set up anywhere with an AC power supply, making them a good option for parties or business meetings.

Warranty

It's frustrating when an appliance breaks, especially when it's outside the warranty period. While a one-year warranty is standard, some brands offer extended coverage for up to five years. This can give you peace of mind and ensure that any issues with your hot water dispenser can be resolved quickly.

Conclusion

There are several factors to consider when choosing an instant hot water dispenser. These include plumbing and installation requirements, as well as the available space in your kitchen.

Under-sink instant hot water dispensers offer efficient boiling water straight from the tap, while countertop models, such as those from Breville and Panasonic, offer a more portable option.

Ultimately, the right choice for you will depend on your budget and needs, whether you are a tea or coffee drinker, and the number of people in your household. Instant hot water dispensers can be a convenient and efficient addition to any kitchen.
