We’ll start our list with our very favorite product, the InSinkerator HOT100. The InSinkerator brand offers several different makes & models of hot water dispenser, as you’ll see through our list. We think the HOT100 offers the best mix of value, functionality, and reliability.

Your biggest hurdle with any of these machines is going to be setting them up, especially if you’re a first timer. We won’t say it’s easy, but this machine does come with everything you need to get started, as well as a detailed, step-by-step instruction booklet.

Once you’re set up, you’ll have a high-quality, high-performance water heating device. It has 750-watts of power to quickly and efficiently heat the water inside the water tank. The water tank itself is sizeable, at 2/3 of a gallon, and has enough hot water for most usages. It’s also one of InSinkerator’s more affordable product offerings, which is surprising given its high level of quality.

The whole system attaches to a sleek metal faucet with easy push-button operation. It’s designed to be hooked up right next to a kitchen sink, or even as a stand-alone unit.

Overall, we really like the Hot100. It’s an excellent mix of quality, performance, and affordability. Nothing fancy, just does what it’s designed to do.


  • Near-boiling water instantly
  • 750 watts of power for quick heating
  • Tank has 2/3 gallon capacity
  • Very affordable


  • Installation is tricky
  • Won’t last as long as more premium product offerings

2. EcoSmart ECO 11 Tankless Water Heater

EcoSmart ECO 11 Tankless Water Heater

Here’s an awesome product variant, especially if you’re looking for an eco-friendly alternative to the traditional instant hot water dispenser. It is designed to address the problem inherent to traditional hot water dispensers – energy consumption.

Traditional hot water dispensers burn energy because they need to continually run to heat the water within their water tank. This product, on the other hand, heats the water as it passes through the unit. This ensures that you are only using energy when you really need it.

This product claims to be 60% more energy efficient, although this would depend on how often you use it.

It has other notable benefits as well. The first is that it is much smaller due to its lack of a tank. It is much easier to find space for the unit, and easier to tuck away. It is also easier to install, with point-of-use installation, and step-by-step instructions.

Overall, it’s a high functioning unit, but it’s not quite as “instant” as the other devices on our list. The water takes time to heat up as the device requires time to get started. But if you are patient, you’ll reap the benefits of additional energy savings.


  • Eco-friendly unit
  • Up to 60% more energy efficient
  • Smaller than a traditional unit
  • Easy to install (comparatively)


  • Not as “instant” as other devices
  • On the expensive side

3. Ready Hot Water Dispenser

Buying Guide

How Do Instant Hot Water Dispensers Work?

If you want to dig a little deeper into this neat area of technology, then you might be wondering how these machines work. It can also help to understand how they work so you can pick the best machine for your personal needs.

Instant hot water heaters, as you’ve come to understand in this guide, are basically just mini hot water heaters that service a faucet. The water tank is connected to your plumbing, where it fills the tank with water. The heater heats the water to near-boiling temperatures, and it is then ready to dispense the water through the faucet.

Most of the machines heat the water through use of an electric coil within the tank. The device is hooked up to your home’s cold-water pipe, where it receives the water to fill the tank. When the faucet is turned on, cold water is let into the tank, forcing the hot water through the top of the tank and out of the faucet. This cold water is heated again, and the process is repeated.

The water is much hotter than a typical faucet’s “hot” setting, with many dispensers reaching temperatures just below boiling.

Why Do You Need an Instant Hot Water Dispenser?

Now that we understand how these devices work, let’s get to the best part – how can these devices benefit you? Here’s a few reasons why these devices are so useful to have.

Home Hacks: Hot water is extremely useful for so many odd jobs around the house. The heat loosens, expands, and releases materials, which is much more useful than you might think. For example, you can remove labels and adhesives, loosen the lids of jars, remove stuck-on candle wax, and more! If ever you need the power of heat, just turn to your dispenser.

Wash & Remove Stains: Hot water is so much more effective for cleaning various materials than cold water. Clothing, furniture, cloths & linens, and much more. It all can receive the power of heat for added effectiveness. Hot water removes stains with ease (even red wine stains!).

Food & Drinks: The water that comes out of your hot water dispenser is close to boiling, which makes it ideal for making meals that require this ingredient. Coffee, tea, soup, oatmeal, and so much more. Even add the water to a pot to decrease the boiling time on your stove.

Miscellaneous: And that’s not all, there are so many little uses for hot water around the house. Making a hot compress, an aromatherapy steam, applying heat to a sore spot, and anything that uses the rejuvenating power of steam.

What to Consider When Buying an Instant Hot Water Dispenser

We’ve given you a lot of options when it comes to hot water dispensers. It’s understandable that you might be a little overwhelmed with choice. It’s best to break your decision down into different factors. Here are some important factors to consider when deciding between tanks:

Tank Material

Tank material influences one of the most important factors – durability. This machine is tasked with holding scalding water for extended periods of time. As you might imagine, it needs to be made with heavy-duty materials. Therefore, a durable tank should be made with strong materials, such as stainless-steel.


Size of the tank is a good consideration as well. The size mainly influences the size of the reservoir for holding the hot water. This allows you to pour more hot water at once before running out. A bigger tank is more useful if you intend to use a lot of hot water at once, such as for cooking large meals, and especially in a restaurant setting.

Of course, the trade-off is that a larger tank will be more difficult to fit under your sink. Consider this as it applies to the installation process.


The power of the tank influences two important variables – speed of heating and the maximum heat. A more powerful tank will more quickly heat the water, allowing you more heat in less time. Most dispensers give you this metric in terms of “cups/hour”, which let you know how many cups of hot water the machine can produce in an hour.

Additionally, a more powerful tank can produce hotter water. Some machines come in as close to 1 degree F below boiling.

Temperature Adjustment

Of course, max. temperature won’t be your only consideration, as you likely won’t want the hottest water all the time. Many hot water dispensers offer a range of temperature that you can set the machine. The bigger the range, the better, as it offers you more choice and control. Some machines even have a digital display which shows the current temperature.


Most hot water dispensers come with a faucet to which the machine is hooked. The most important consideration here is style. You want a faucet that fits with your current kitchen accessories, and won’t stand out in a bad way.

Many dispensers offer several different faucet options. Needless to say, this makes it easier to find your ideal style of faucet.
