Best Hot Water Dispenser Reviews

1.      Top Pick: InSinkErator H-Wave Involve

The top pick on our list comes from InSinkErator. They make excellent hot water dispeners. This model, the H-WaveC-SS, is a perfect example.

For starters, this unit has an adjustable thermostat from 160˚F to 210˚F and a 2/3 gallon hot water tank. This makes it great for those tasks that require near boiling water or those that require warm water. It really gives you a big range to do just about everything.

Next, this unit is made out of an extremely durable stainless steel. Perfect for any kitchen. Not to mention that it is chrome colored and has a traditional style that looks good in just about every kitchen. Much better than some of the options in this category.

Now, all of that is great. However, the real reason we give this unit the top pick is because of the excellent warranty. It is an in-home limited 3 year warranty. This comes with free house calls to repair your unit over the duration of the warranty. This is the best warranty in the industry and why we rank this unit as the top choice.



  • Excellent in-home limited warranty.
  • Wide range of temperature.
  • Looks great in any kitchen.
  • Child safety lock.
  • Compatible with the InSinkFactor filtration system (sold separately).


  • Slightly more expensive than other units.

2.      Runner Up: InSinkErator H-Wave Involve

InSinkErator H-HOT150SN-SS

Next on our list is another InSinkErator. Yes, they really do make good units. In fact, all of the top rated hot water dispensers on Amazon are made by InSinkErator. Go figure.

Anyway, this unit offers the same heating specs as the previous one mentioned. Except in this case it only has a 1 year in-home limited warranty. This is still a great unit and we added this here in the event that the H-Wave is out of your budget.

This unit also has a slightly different faucet than the H-Wave. So check that out if you did not like the look of the faucet on the H-Wave.



  • Adjustable thermostat has a big range.
  • 2/3 gallon is big enough for heating.
  • Faucet comes in stain nickel and chrome.


  • No lockout safety feature.

3.      InSinkErator H-Wave Involve

Westbrass D271H-12

The Westbrass D271 Velosah comes in third on our list. We like the all brass construction of this unit even though it does add to the cost a little bit.

Now, it has a slightly smaller tank than the InSinkErator dispensers. However, the difference is extremely small. The Westbrass has a 5/8 gallon holding tank while the InSinkErator has a 2/3 gallon tanks. This difference is basically negligible. It is a 750 watt unit.

Don’t let that smaller tank fool you though. It can still deliver a whopping 100 cups of hot water per hour, which is plenty. Most people do not use more than a few cups of hot water at a time.

Finally, this has an auto-off functionality to increase safety. Basically, the switch automatically turns off when you stop applying pressure. This makes it safer for older folks, but it can be slightly annoying.



  • The faucet looks beautiful and is brass.
  • Auto-off feature is very nice.
  • Adjustable heat.
  • 1 year limited warranty.


  • Most expensive option on the list because of the brass faucet.

4.      Top Hot & Cold Water Pick: InSinkErator H-Wave Involve

Ready Hot RH-100-F560-CH Dispenser

The Ready Hot unit makes the list because of its dual lever functionality. You get hot water and cold water. Really, this makes it quite unique in the hot water dispenser category where most of the models are exclusively hot water.

The hot water goes up to 190 degrees Fahrenheit while the cold water is really just room temperature. This gives you a nice range of temperature. We wish the unit had a cooling component. But that’s ok. You still have the option to do that with this unit.

It also does not have the safety feature seen on other models. Now, this might sound bad, but it really is not. It allow you to fill up a container with hot water without having to keep your hand on the lever. Super convenient.



  • Hot and cold water.
  • 5 quart tank.
  • Chrome faucet looks great.


  • No safety lock (can be a pro).

5.      Hot & Cold Dispenser Runner Up: InSinkErator H-Wave Involve

Yes, another InSinkErator dispenser on the list. This one is made of brass, so you get the durability you would expect from a brass product Plus, it looks much better than any of the other options (we’re big on looks here at WPH).

Now, this is a hot and cold dispenser, which is nice. Like the other hot and cold models this one is really a hot and room temperature model. They say cold because room temperature is cold compared to the 210 degrees Fahrenheit of the hot water. Yes, the hot water really does get that hot. It’s basically boiling at that point. Keep in mind that this is adjustable, so you can have it at 160 Fahrenheit or 210 Fahrenheit or anything in between. Quite nice in our opinion.

Ok, the best part about this is that you get a 3 year in-home limited warranty. This means that InSinkErator will come to your home to do any warranty repairs for 5 years. Super convenient, which is why InSinkErator ranks so highly. They also make great products in general.

This unit can also easily attach to this their filtration system. Meaning that you do not have to purchase an under sink water filter. You can still check out our reviews of under sink filtration devices though. Lots of good products in there.



  • 3 year in-home limited warranty.
  • Easy DIY installation.
  • Hot and cold option.
  • Automatic shutoff on the hot lever.


  • This is the most expensive unit on our list.

3 Benefits of a Hot Water Dispenser

Using a hot water dispenser has some definite advantages over using a kettle or a pot. Here are just a few of those advantages.

  • Instant

That’s right. You don’t have to stand around and twiddle your thumbs while you wait for the water to boil. I mean, everyone hates waiting around for their water to boil.

A hot water dispenser eliminates the wait time. You simply just press the button and hot water comes gushing out the dispenser into your glass. A big advantage when you want a quick tea break.

  • Use less Energy

Another big advantage is that the dispenser will use energy than a stovetop. This means that you actually save money when you make the switch. Obviously the amount of money you save will depend on the price of your electricity and the frequency that you use hot water. You will save money on a long enough timeline though.

  • Better Tempeature

You know how when you drink tea or coffee and just think it tastes hot. Sometimes it even burns your tongue and you don’t taste anything other than “HOT.” That is because you use boiling water and not the proper temperature for making your tea or coffee.

In reality, the ideal temperature for tea or coffee is around 160-180 degrees. Not the boiling point that you probably know. A water dispenser means you do not have to wait for your hot drink to cool down. Nice!

6 Things to Consider Before Purchase (Buying Guide)

How to know if water is hard?


You want to choose a brand with a good reputation and not one of the fly by night operations that seem prevalent in this industry. InSinkErator is the most well known brand in the industry, but there are other brands (Waste King, Ready Hot) that offer an equally good product. If you have any questions about good brands, then feel free to email us or leave a comment. We’ve been doing this a long time and know just about everything.


This relates to brand. Only good brands offer good warranties. Now, InSinkErator has the best warranty in the industry. However, to be quite honest these systems are durable and it is unlikely that they will break within the warranty period. Just being honest.


The most important buying decision. You definitely do not want to skimp on price in this category. The lowest price you should pay for a water dispenser is around $170. Most of the midrange products will cost in the $250-$350 range. Anything over $350 and you are just paying for a nicer faucet. This is fine if you want faucet, but the quality of the water and heating will be the same as a $270 unit.

water filter cost

Make sure to factor in your monthly electric bill. You can expect an extra $30 or so to your electric bill at the minimum. It might be higher depending on the wattage of your unit, the temperature you keep it at, how often you use it, the cost of electricity in your area, and the temperature of tap water (colder tap water means more heating is required).


You want to make sure your unit has at least 750 watts. This means that it will take less time to heat the water, which leads to more hot water in your cup. Too much watts will also cause a higher electric bill.

Hot & Cold or Hot

You have to choose between hot and cold or only hot. Keep in mind that the cold will still be room temperature. In this sense, you can just use your sink faucet and the effect will be the same. Some homeowners prefer to have a room temperature option though.


If you want a unit that filters water, then make sure to choose one that you can attach a filter on top of. Check out our reviews of under sink water filters. You want to purchase this before installing your water dispenser. It just makes the process so much easier to do both at the same time.

Installing a Hot Water Dispenser

Installing these is not a task we recommend. Calling plumber to install this is your best option. Trust me, plumbing might look easy, but the amount of precision required makes it rather difficult. It also requires drilling directly into your sink. If you do this incorrectly, then you will have a big hole in your sink. Not exactly worth it.

A plumber should be able to install one of these for under $200. Call around and get quotes though. Every licensed plumber will know how to install a hot water dispenser.

If you still want to venture out and install your own water dispenser, then you can check out this guide to installing a hot water dispenser.

Hot Water Dispenser FAQ

  • Do you have to hold the handle to get it to continue to let out water?

Yes. You definitely have to hold the handle to dispense water. This is a safety feature built into all hot water dispensers.

You cannot just leave it open like a normal faucet. This might sound inconvenient, but when you see how hot the water is you will realize that this is a very safe idea.

  • Are these battery powered?

You will need to plug it into an electrical outlet. None of the units listed have a battery pack. In fact, no hot water dispenser is battery powered. That is a very good idea though!

  • Do I supply water from the hot water line or cold water line?

Water is supplied by the cold water line. It is redundant to use the hot water line and may damage the unit. Do not supply this with hot water!

  • Do I have to drill through my counter to install this unit?

Yes. You will have to drill through the countertop. This is why we recommend hiring a professional because it is very easy to damage your counter.

  • Are these loud?

No. They should be quiet. You should not hear these. Think of it as a “set it and forget it” type scenario.

  • Can I connect this to my main faucet?

No. The whole unit is self contained and that is not possible.

  • Do these units have a standby mode?

Unfortunately they do not have a standby mode. Many homeowners will simply unplug the unit if they will not use the faucet for an extended period of time. Alternatively, you can also adjust the unit to the lowest setting.

Final Thoughts and Recommendation

All in all, a hot water dispenser makes a great addition to your home. You get hot water almost instantly and do not have to deal with boiling water in a kettle or anything like that. In fact, a hot water dispenser will save you a large amount of time each month. Remember, time is the most valuable asset on the planet. We do not get more time. Do not waste it.

As for our recommendation, InSinkErator H-Wave Involve is our personal choice. It just does everything that we want. We personally do not mind that it does not have a cold water setting. That is what the normal faucet is used for anyway.
