The Basics: What Is an Instant Hot Water Dispenser?

Instant hot water dispensers are the new-age substitutes for electric kettles. These devices heat the water to a near-boiling temperature and then store it until it’s needed. Depending on the type of water dispenser you get to fill a cupful of steaming water with a push of a button. If you purchase a larger under sink hot water dispenser then you get a continuous stream of hot water by turning the faucet.

Most hot water dispensers are multipurpose. We can divide them into four primary categories, which are as follows:

  • Under sink hot water dispenser
  • Coffeemakers and boilers
  • Instant hot and cold water dispensers

Why Do People Buy It?

The benefits of this contraption lay in its ease of use and feasibility. Plus, unlike a kettle, these appliances are versatile.

Here are a few examples:

  • You can use hot water to thaw frozen peas and other vegetables.
  • You can use it to make pasta/macaroni.
  • Warm baby bottles.
  • Clean kitchen counters and other surfaces with a cloth dabbed in warm water.

In short, the hot water dispenser is a wonderful way to tackle multiple kitchen-centric tasks with one appliance.

The Mechanism: How Does It Work?

The simplest way to understand the instant hot water dispenser’s mechanism is to think of it as a mini water heating tank. Just like the tank, it heats the water that enters the tank and then stores it until you need it. The only difference is that hot water dispensers usually accommodate a single faucet instead of a whole house.

Here’s a breakdown of how it works:

  1. Cold water enters the system through your main plumbing line.
  2. The heating coil/electrical component bring the water to a near-boiling temperature (or required setting).
  3. The hot water starts to rise and accumulates in the storage area.
  4. Hot water comes out of the connecting faucet whenever you turn the tap.
  5. The tank refills simultaneously to ensure that you get fresh water each time.
  6. The heating cycle continues.

Pro tip: You can adjust the temperature via its thermostat if necessary.

That’s it! Due to the continuous water supply under the sink, you never run out of hot water. In many cases, the hot water dispensers will purify the water if they’ve got a built-in filtration system.

What about the countertop hot water dispensers?

Hot water dispensers like these work in a similar manner. The main difference is that they have a limited supply of water. That means you’ll have to fill them constantly throughout the day when necessary. The other difference is that the device works independently without the need for a faucet. Plus, the hot water moves downwards instead of upwards when you use the dispenser.

The Benefits: Why Do You Need One?

You probably think that hot water dispensers are only useful for making tea/coffee or hot chocolate. That’s what most people assume too. However, that’s not the case. When used properly, hot water dispensers can provide you with multiple benefits.

Let’s look at the main ones:

1. Great Alternative to a Dishwasher

Hot water dispensers are usually attached to faucets in the kitchen sink. It’s an ideal place for them because then you can use the steaming hot water to wash your dishes. The near-boiling temperature of the water gushing out of the faucet makes it easier to clean dirty dishes.

For it’s a fact that hot water helps breakdown grease more quickly than cold water. In addition to this, the high temperature will kill off bacteria and germs clinging to your dishes. So it makes it equivalent to a sterilizer. Plus, sterilizing your utensils with hot water is safer than using harsh chemicals to do the same thing.

The great thing is that you don’t have to spend too much time boiling the water here. You can simply place the item under the faucet and sterilize it with hot water. We feel that this is a great investment for households with babies and young children. You can use this nifty device to sterilize bottles, pacifiers, utensils, and washable toys without any issues.

2. Saves Time

Don’t have time to boil water?

Install a hot water dispenser and get rid of the time consuming process. Hot water dispensers are a blessing for people with busy schedules. Once you’ve installed the dispenser you get on-tap hot water in an instant. So all you’ve got to do is go to the hot water dispenser and pull a lever/turn the faucet and use the hot water anyway you want.

In most cases, the appliance provides hot water at your desired temperature. This, in turn, allows you to use it in various scenarios.

It certainly minimizes the time taken to boil the water in a kettle or a pot. It’s also more feasible for you to clean a few dishes under the hot water instead of waiting for the dishwasher to get filled. From fixing tea to delicious instant ramen meal–hot water dispensers can cater to all your needs. Plus, it does this without wasting your time.

Apart from this, it’s convenient for people with mobility issues (i.e. elderly folks and disabled people). They’ll find hot water dispensers more manageable than regular kettles and pots. Plus, its numerous uses will ensure that they get a sense of independence when they wish to work in the kitchen.

3. Cost-Effective

We understand that for some of you, hot water dispensers will sound like a costly purchase. However, the appliance will come through for you in the long run. That’s because it gives you value for your money by accommodating several tasks in the kitchen.

The biggest advantage is that it’s energy efficient. The hot water reservoir ensures that you don’t have to heat the water from scratch every time you need it. In this way, you end up saving more energy and power when you use a hot water dispenser as opposed to a kettle.

You can expect to see a significant reduction in your electricity bills when you install this handy device.

4. Minimizes Limescale Build Up

Did you know? Constantly heating hard water in kettles and pots leaves behind traces of chalky deposits behind. We call this residue limescale and it usually accumulates at the bottom of your utensils over time.

Not only is limescale difficult to remove, but it also poses a lot of health risks. The limescale will eventually start affecting the taste of your water and in turn the beverages you make with it.  Besides this, it contaminates your water and makes it unsafe to drink.

Fortunately, most hot water dispensers tackle this problem by using limescale filters. The filters keep the limescale formation at a minimum. Plus, the hot water that comes out of water dispensers is less likely to have limescale in it than one from the damaged kettles.

As a result, you have access to clean hot water in your kitchen. Plus, you don’t have to keep changing utensils anymore because they won’t get affected by the hard water.

In short, you’ll be missing out on a lot of things if you don’t install this multifaceted machine in your kitchen. In fact, the dispensers are equally useful in school staff rooms and workplaces too.

The Installation: How Do You Install an Instant Hot Water Dispenser?

Image description: Installing a Hot Water Dispenser

Installing a hot water dispenser is pretty simple. Most of the products reviewed on the list allow you to take the DIY-route instead of calling in a professional. On the other hand, the boilers and coffer makers only need a basic setup and plugging outlet.

You just need the right tools, basic DIY skills, and an instruction manual. However, the installation process may vary from product to product. So we can’t make any guarantee on that.

With that being said, we’ve created a step-by-step guide for you to explain the installation process. The steps below will work for hot water dispenser with faucets.

Here’s what you need to do:

Step 1: The Prep

It is important to get the area prepped up before you start installing the hot water dispenser. It’ll ensure that you don’t waste time finding or cleaning things while you’re installing the device. The first thing to do is to read the instruction manual that comes with your unit.

These are the other things required for you prep:

  • Clean the area under the sink before you get started.
  • Shut off the water supply to prevent any hindrance during installation.
  • Get your tools and kit ready.
  • Unpack your faucet and dispenser from the packaging.
  • Make sure that you’ve got all the parts at hand.

Step 2: Drill a Mounting Hole

You might need to create a mounting hole for the dispenser’s faucet. For this step, you’ll need a drill, drill bits, and safety glasses.


  1. Choose a spot to mount your hot water dispenser.
  2. Mark that area (preferably the center of that area) for precision.
  3. Drill a ¾ inch hole on the spot. (You can make a pilot hole first for accuracy.)

You should probably inform the superintendent of your building or landlord of your house if you’re renting the place.

Pro tip: You can skip this step if you’ve already got a hole in your sink.

Step 2: Mounting the Faucet

Mounting the faucet is a pretty straightforward process. You simply place it on top of the mounting hole and make sure that its seal is seated on your dispenser’s valve. After fixing its position, you move under the sink and start securing the faucet.

You should use nuts and tools to tighten the faucet properly so that it doesn’t wobble or rotate.

Step 3: Install the Water Tank

In most cases, you’ll install the hot water tanks under the sink. For that, you need to mount them in a vertical position on the same level as your plumbing line. Try to place it near the water supply and electrical lines.

The standard distance between a tank and faucet is 16-inches or less. Besides this, you need to leave enough room for drainage from the underside of your tank.

The next thing you need to do is:

  • Mark the selected spot with a pencil.
  • Drill then necessary holes (two-eighth inches) for the screws.
  • Secure then water tank with the help of nuts and bolts.
  • Make sure that the dispenser is properly tightened to avoid issues.

Step 4: Making Connections

Next, you are supposed to connect the plumbing line with the dispenser. You do this by installing a compression tee fitting that connects them.  You’ve got to options to make this happen; either you use a saddle tee as a substitute for the compression tee. Or you have to cut the copper tubing to form these connections. We suggest doing the latter to get the proper fittings.

Once that’s done, you need to connect the inlet to the compression tee. After which, you join the feed line from the faucet to the upper part of the tank.

Caution: You’ll have to make slight changes to this process depending on the dispenser unit you’ve purchased.

Step 5: Final Steps

You need to do a trial run after you’ve finished installing the faucet and dispenser. The key here is to not plug the tank until you’re sure that the water supply is consistent. To do this you need to switch on the cold water supply to fill the tank. Then turn the faucet to check your connections.

Once everything is clear, you can close the faucet and then plug in the water dispenser. Set the temperature and let the water heat. Then run the faucet again to see how well it works.

Conditions: Things to Keep in Mind When Installing a Hot Water Dispenser?

Here are a few things to consider when you’re installing a hot water dispenser:

  • Position: Hot water dispensers come in a variety of shapes and sizes. If you want anunder the sink hot water dispenser then make sure that there is enough space down there. The same rule applies tocounter top hot and cold water dispensers. It will ensure that your hot water dispenser isn’t too big/small for your kitchen.
  • Add-Ons: Many hot water dispensers come with built-in filters, but many don’t. It’s always better to get a system that filters your water. That’s because it ensures that you get clean and sterilized water every time.
  • Aesthetics: Like any fixture in the household, style and shape matters. So try to get hot water dispensers and faucets that match your aesthetic sense. You don’t want to get something that looks like an eye-sore in the middle of your well-decorated kitchen.

Let’s Sum It Up…

Long story short, hot water dispensers are practically perfect in every way. They cut down the time spent in making a hot beverage and efficiently handle other tasks too. Moreover, if you install them beneath the counter then you get to multiply its usage. From cooking, cleaning, to sterilizing–the proficient product does it all.
