With the best instant hot water dispenser, many things in the kitchen that once were a hassle, will become a source of joy.

Quick coffee and tea without a kettle, instant boiling water for cooking, tomatoes peeled and vegetables blanched within seconds are just a few of the countless boons that come with having a good hot water dispenser on your kitchen sink. Saving much space and time, an instant hot water dispenser can even help lower your bills. Instead of summoning hot water from a distant water heater and sending gallons down the drain until it actually gets any warm, an undercounter water heater connected to a special faucet can give you hot water on the spot and at any temperature up to 200°F.

With all the great reasons for installing such a system in your home, the question is finding the best unit that will work ceaselessly to answer your needs. This page features instant hot water dispenser reviews that were written with the intention to help in your search. To provide an evenhanded picture, each review lists the cons as well as the pros of the product at hand. Having picked up all the information on this article, it will be up to you to decide the best hot water dispenser for yourself.

Choosing a Good Hot Water Dispenser

The first step to finding a great instant hot water dispenser for your kichen is to be clear on what you are looking for. A dispenser system is made up of a tank and a faucet that can be purchased together or separately.

Water Heater Tank: Installed under your kitchen sink, these special water heaters are different from ordinary point-of-use mini-tank water heaters due to their ability to heat the water to near boiling temperatures. As we will see in the reviews below, some manufacturers take the easy route of getting the tank from another supplier and resell it with their own faucets. It is probably a better idea to buy the tank from the real manufacturer rather than a middleman.

Faucet: Hot water dispensers need a special open-vent faucet. What makes this special is that it cuts off the water supply to the water tank when you close the faucet. That prevents extra water pressure building up on the water heater that is already highly pressurized by the steamy water inside. With an ordinary faucet, a hot water dispenser system would either leak or not work at all. An instant hot water faucet must be well-built so that it does not leak or drip, which would simply render the whole system useless.

Now that we have discussed what you should be looking for, we can proceed to review the products of the major brands in the hot water dispenser market.

Whitehaus Hot Water Dispensers

The first brand to be reviewed is the Whitehaus Collection, known for its decorative and durable kitchen fixtures. Concerning hot water dispenser systems, it is hardly a popular choice but deserves to be in the list because its products are just too beautiful to ignore.

Whitehaus has a wide variety of hot water faucet designs that range from extra-classic to ultra-modern and each model has numerious finish options so you can rest assured that there is a Whitehaus model out there that will perfectly fit in with the rest of your kitchen. Whitehaus product range is permeated by elegance that highlights the upmarket quality. The prices start just above 200$ and goes up to several hundreds.

Probably due to the price tags, not many people install Whitehaus units so user feedback is rare. According to the few existing user reviews about Whitehaus hot water dispensers, people laud the high-end finishes but some had problems with the installation and parts supplied by Whitehaus not fitting each other. This is expected because although the faucets are made by Whitehaus, the heating tank is not.

The hot water tank used in Whitehaus instant hot water dispensers is the exact same unit produced by Anaheim and sold by Waste King. The only difference is the WH-Tank label plastered on it by Whitehaus and the higher price tag. In theory, you could try buying a Whitehaus hot water faucet for the sleek design and connect it to a Waste King water heater tank and get the best of both worlds. What you need to keep in mind is that product descriptions of Whitehause faucets clearly urge you to use the WH-Tank with the faucets so there is this possibility that it just won't work.

All in all, the high-end looks of Whitehaus hot water faucets are eclipsed by the fact that it resells an economy-class heating tank instead of making one of its own. It is still an option to be considered just for the sake of its beautiful fixtures but you should keep in mind that InSinkErator company reviewed down the page offers an equally stylish variety of faucets coupled with high-quality water heater units of its own at a comparable price.

Franke: The Little Butler

Franke is a well-known Swiss company that manufactures high-end kitchen and bathroom fixtures and its instant hot water dispenser series named "The Little Butler" has become the choice of many who want a reliable hot water source at the kitchen. Opting for a reputable brand name is a rational choice but the overall user satisfaction turns out to be mediocre suggesting Franke's expertise on hot water dispensers cannot compete with that of the specialized hot water dispenser manufacturers such as Waste King and InSinkErator.

First, let us have a look at the water heater. Like Whitehaus, Franke buys the hot water tank from Waste King and sells it for double the price.

The hot water dispensing faucet is a genuine Franke product. It looks fine with a sleek design and a number finish options. As the name suggests, it is very little: a mere 8 inches in height. The actual user experience with the Little Butler does not seem very bright as customers rate it poorly based on a number of issues.

A serious issue with the Little Butler is the recurrent complaints about leaks. The culprit is almost always the plastic lining in the hose that connects the tank to the faucet and it melts when exposed to boiling water.

Franke Little Butler series hot water dispensers are also reported to drip and sputter rather frequently. That suggests the faucet valve is not strong enough to deal with the pressure of near boiling water and although a drip or two is not going to ruin your day, it is an annoyance you do not deserve to experience after a paying a premium price for the product.

To summarize, although Franke is a decent brand, the fact that its water heater is actually made by Waste King and the occasional complaints by customers cast doubts about whether it is the best choice for an instant hot water dispenser.

Waste King H711-U-CH Hot Water Dispenser System

The H711-U-CH Hot Water System includes a faucet and a water tank that together cost less than any hot water dispenser system in the market. Waste King does that not by compromising on quality but because it is the actual manufacturer of the thing, i.e. this is the real deal!

The water heater tanks we've seen so far including this one, are all the same model AH-1300 built by Anaheim Manufacturing, which is the parent company of Waste King. So, when you buy from Waste King, you will be buying the product directly from the manufacturer instead of a middleman. In addition to the price advantages, Waste King faucet and parts are more likely to fit each other, making the installation easier and the overall hot water experience better. Now that we are reviewing the company that actually makes the thing, it is time to go into the details of this hot water tank.

AH-1300 holds 5/8 gallons of hot water at any time for instant delivery. It has a 1300 watts electric heater that works to heat the incoming water to near boiling temperatures and keep it hot. This water heating system can give you 100 cups or 6.25 gallons of very hot water per hour. Although the instant water delivery capacity should be expected to go down in colder areas, a few gallons of boiling water is more than you will ever need at a time. The unit has a one-year warranty.

The tanks seem to work fine with the faucet as the customers often end up quite satisfied with the Waste King system. The only recurring complaint I've noticed about the Waste King hot water dispenser is the occasional difficulties people come across in installation. It looks like the instructions are a bit murky and the box sometimes lacks some gaskets and things but nothing that cannot be easily acquired at the local hardware store. Once you get past the installation, it works and it does that at half the price of other brands that essentially sell the same thing with better-looking faucets.

In short, I recommend Waste King hot water dispenser for a fairly simple reason: It is very cost-effective. If you want a basic hot water dispenser that does the job and you want to get it running for under 200$, look no further.

InSinkErator Instant Hot Water Dispensers

If the average hot water dispenser with the good price is not enough for you and you'd rather have the truly high-end unit, you should check out InSinkErator. As a manufacturer that specializes on garbage disposals and other products related to the kitchen sink, InSinkErator's hot water dispensers deserve to be named the best thanks to the newly designed water heater, sleek and well-built faucets and the outstanding warranty.

InSinkErator has not always been the best hot water dispenser supplier. Older models had flaws such as a stainless steel tank soldered with another metal that turned out to be very prone to corrosion and plastic fittings that came into contact with the extremely hot water tank. They rusted and leaked in less than five years. The good news is these inferior models are no longer available so you cannot buy them even if you want to!

The latest HWT-F100S water heater by InSinkErator has an all stainless steel tank that should resist corrosion and last much longer than the previous tanks. The 2/3 gallon tank uses a maximum 750 watts of electric power and can supply up to 60 cups of very hot water per hour. As expected, HWT-F100S is rated quite highly by users as a functional and reliable water heater. Any negative customer reviews are usually by people who apparently owned one of the older tank models and came back to slam InSinkErator when it finally failed. In fact, the only legitimate complaint about the new InSinkErator hot water dispensers is about a gasket that is needed to connect the new tank to an old faucet model but is not shipped with the tank. That sort of brakes the installation if you are replacing an old tank but you can eventually buy the part by calling InSinkErator. Needless to say that brand new InSinkErator faucets are shipped with everything you need for the installation.

InSinkErator absolutely outshines all other brands when it comes to the warranty. You get a three-year warranty for the water heater and a five-year warranty for the faucet. The customer service gives the impression that they do want their customers to end up happy with their products as they even check and reply to Amazon reviews to find discontented people and help fix their issues. It is big plus when a company actually stands behind its products.

Another reason that I like InSinkErator's water heater over others is that it is actually hotter. While the Anaheim tank is capped at 190 °F, InSinkErator HWT-F1000S Hot Water Tank can heat water up to 200 °F. Although the difference looks trivial at first, 200 °F is a critical temperature that will give you an edge in various kitchen tasks. For instance, according to Black Bear Micro Roastery, the best temperature to brew coffee is between 195 °F and 205 °F and defitinely not below 195 °F.

As for the faucets, InSinkErator has a wide range to choose from. The most popular Indulge Contemporary series are the basic gooseneck faucets. They have a slightly better price than the other series as well as twelve finish options. Indulge Antique series have a more classic, elaborate design. They are also available in twelve distinct finishes ranging from mocha bronze to french gold. Indulge Modern series blend a neat and durable look with nickel and chrome finishes. There is also a cheaper InSinkErator faucet with a black, plastic handle. People buy it because of its low price but it gets some bad reviews from customers due the handle that is easily broken. I suggest you just ignore that one and get one of the high-end brass faucets.

In conclusion, I see no reason for not calling InSinkErator the best instant hot water dispenser in the market. While the more economical Waste King should also be able to provide the quick hot water you want, InSinkErator does it in a more reliable and stylish way and with a much better warranty. If you want a hot water dispenser that stands out from the rest, InSinkErator could be what you seek.

Best Electric Tankless Water Heaters In a home with no natural gas, an electric storage water heater can send a small fortune down the drain over the years. In that is case for you, a tankless electric water heater is probably the quickest way to stop the waste.

Best Gas Tankless Water Heaters Once installed and connected properly, a tankless water heater that depends on propane or natural gas as its energy source can provide ample hot water even for quite a large house with surprisingly low bills.

Best Heat Pump Water Heaters : With heat outputs that more than double their energy input, heat pumps designed as residential water heaters are the gold standard of efficiency.

      So, I read your reviews and see that you recommend the InSinkErator HWT-F100S. I had two of the old models that developed leaks very quickly, but based on your review considered buying another. Have you seen the reviews on Amazon and other places for this model? They do not support your recommendation.

      3 InSinkErator units installed in two different locations in 2015 (one a replacement for the first defective unit). Both continue to leak cold water into the sink. Seems to be a problem with condensation caused during the hot water heating cycle. Guarantee seems to be worthless since replacement units have the same problem. Looking for a different unit.

      "A serious issue with the Little Butler is the recurrent complaints about leaks. The culprit is almost always the plastic lining in the hose that connects the tank to the faucet and it melts when exposed to boiling water."

      This hose has leaked on me twice...first time flooding the bottom of my pressboard cabinet, and just today I caught it again, not flooding as bad, but still flooding. It's a rubber hose supplying almost boiling water...WTH?

      Any fixes to this beside getting another brand like the InSinkerator?

      I saw someone mention a silicone tube? It really is paranoia wondering when the next leak will occur, but it's hard to live without one of these. Help!
