We work with over a hundred instant hot water systems each year. So we keep up-to-date on the current offerings.

Without further ado, here are our choices for the best instant hot water taps for 2018.

InSinkErator Instant Hot Water Dispenser

The InSinkErator Hot Water Tank is a 2/3 gallon (2.5 liter) tank which is the perfect size for most kitchens.

It’s compact but large enough to give you enough hot water to handle most tasks without having to wait for the water to reheat. Old water gets replaced by new water and is heated quickly as you use it.

The pros of this hot water tank is that it gives you access to boiling water fast. Its temperature ranges from 160 degrees F to 210 degrees F (boiling point for water).

We’ve installed many of these InSinkErator instant hot water dispensers and they work just great.

When you purchase this instant hot water tank you have 8 faucet options to choose from, and they are built with safety in mind.

The faucets are called Modern, Contemporary, Antique, Tuscan, View, Wave, Contour, and Classic. Click on the pictures below to take a closer look and check current prices.

You can pick between Hot Only or Hot & Cool water faucets with this InSinkErator system. You can also hook the tank up to a filter, giving you instant filtered cold drinking water.

The one con of this hot water tank is that it might be sold separately from the faucets. To make sure you get all the parts to install this system correctly, we recommend purchasing one of InSinkErator’s faucets designed to be used with this tank.

The InSinkErator tank comes with a 3-year in-home limited warranty.

In our experience, this is one of the best instant hot water dispensers for 2018 for home use.

Bosch Tronic 3000 T Hot Water Dispenser

If you don’t absolutely need boiling hot water, the Bosch Tronic 3000 Tank is a great option.

Its temperature range is 65 degrees F to 145 degrees F. It’s perfectly capable of making a hot cup of coffee or tea. In fact, the best temperature to brew tea is at around 150 degrees F, because the taste of tea is sensitive to hot water and boiling water damages the leaves.

The Bosch Tronic is available in three versions: 2.5 Gallon Mini Tank (ES2.5), 4 Gallon Mini Tank (ES4), 7 Gallon Mini Tank (ES8).

The 7 gallon is intended to feed two sinks simultaneously. However, the 7 gallon tank needs to be hardwired, whereas the other two smaller tanks are plugged in.

The units are designed to work with your existing sink setup by tapping into your cold water line, rather than installing it to an extra faucet.

The pros with this instant hot water tank are the long warranties. You get 6 years limited warranty on the inner tank, and a 2 years limited warranty on other components.

This is also one of the cheapest instant hot water tanks you can purchase. You should be able to purchase any of the three sizes at under $200, whereas other hot water tanks start at $250 and up.

Bosch is a reputable brand that we can vouch for.

The cons of course are that it cannot provide boiling hot water. It can give you a head start, but if you need boiling water you’ll have to use the kettle or stovetop.

It can also be a bit clunky especially if you order the larger size.

Ready Hot Instant Hot Water Dispenser

We have a couple of Ready Hot instant hot water dispensers that we want to share with you today. These are quite similar to the InSinkErator tank.

The first is the Ready Hot 100. This 2.5 quart tank (just under 2.5 liters) can put out water between 140 degrees F and 190 degrees F. At its maximum temperature you get very close to boiling water.

Ready Hot makes a hot only or hot and cold water faucet available in chrome or brushed nickel to go with the tank.

The pros of this instant hot water tank are good capacity, good efficient system, and simple design.

The cons of this instant hot water tank are the 1-year warranty and the clunkiness. It’s definitely not as modern-looking as the InSinkErator.

If you want a longer warranty period, check out the Ready Hot 200 instead.

The 200 is a stainless steel tank with the same 2.5 quart capacity as the Ready Hot 100. It features water between 140 degrees F and 200 degrees F (hotter than the Ready Hot 100) and a 3-year warranty.

Waste King Instant Hot Water Dispenser

Waste King, InSinkErator’s direct competitor when it comes to garbage disposals, makes four faucet and hot water tank combos for sale.

You can purchase their Quick and Hot Instant Hot Water Tank with their Coronado faucet, Laguna faucet, Madera faucet (hot and cold), or Tahoe faucet.

The tank itself is a 5/8 gallon tank (just under 2.5 liters) with a temperature range of 140 degrees F to 190 degrees F. So it’s almost identical to the Ready Hot 100.

It even shares the same pros and cons as the Ready Hot 100, such as the simple design, 1-year warranty and clunkiness.

It is priced similarly as the Ready Hot. You should be able to purchase the tank and faucet for just over $200.

Our #1 Choice

If you ask us to pick one dispenser between all the choices we recommend, we’ll have to go with the InSinkErator Hot Water Tank.

The reasons are that you get a 3-year in-home warranty service with the product, it’s modern-looking product without the clunky retro feel, you get to choose from many faucet styles including hot only or hot and cool faucets, and out of all the choices it’s the only one that provides hot water at boiling point.

Combining the hot water tank with InSinkErator’s faucets and filtration products, this is currently the best instant hot water dispenser system you will find.

Your hot water tank will get some wear and tear overtime, so don’t be surprised that you have to replace it every few years. Remember that this is something you’ll likely be using every day, but some people forget and they complain that their dispenser broke too soon. We just want to make sure you’re not placing unrealistic expectations on your hot water tank.

Hope this helps!
