How Does A Water Dispenser Work? (Simple Steps!)

How Does A Water Dispenser Work?

How does your water dispenser really work? Thanks to these devices, you can enjoy either cold or hot water any time you want without even thinking about the process. Is there only one kind of this dispenser out there or do you have options between different models?

The most popular water dispenser, or what most people know, is the one with those huge water bottles on top. In countries where tap water is not safe for drinking, these water bottles use filtered water, but it will also work with water from the sink. The main advantage of this gadget is that it provides warm water for tea or cold water perfect for warm weather.

Where Can You Find Water Dispensers?

Water dispensers are quite common in residential homes, simply because they are convenient. Plus, it is another option when tap water is undrinkable or too hard, with customers ordering filtered water to use with these gadgets.

Many businesses, stores, and offices use them as well. Because of the high number of people in these places, there is a demand for drinking water. A water dispenser is perfect for meeting the needs of everyone who uses it. Not just hot or cold water is available, as you can mix both to reach the perfect temperature. Plus, by using filtered water, there is a reduced risk of anyone having issues with the drinking water.

One of the biggest advantages of water dispensers is the fact that they reduce the consumption of filtered or mineral water in small bottles that creates a lot of trash. Most of these throwaway bottles do not end up being recycled, so a dispenser is much more friendly to the environment. By offering an option to access drinking water through these dispensers, employees and customers will not have to buy any bottled water.

What Kind Of Water Dispensers Are Out There?

What Kind Of Water Dispensers Are Out There?

There is actually more than just one kind of water dispenser available. The first one is the more common, called the bottled water dispenser. The second is called a Point of Use (POU) water dispenser. This includes many different forms like wall-mounted dispensers and ones with coolers, but they all fall under these 2 types.

The bottled water dispenser uses those 5 gallons (20 to 30 litre) bottles that are then mounted on the water dispenser. These bottles can be delivered to your home or can be bought in the store. Once they are empty, they can be refilled and reused.

On the other hand, the Point of Use (POU) model is one that is mounted in place, with the water supplied from the tap or through the waterline. In some cases, they have a built-in water filter. If not, an additional water purifier can be connected to clean the water. Most of these models also have the cooling and heating function of bottled water dispensers.

Another subcategory of water dispensers have a small water fountain. They also receive water from the pipes and are usually installed in movie theatres or parks.

How Does A Water Dispenser Work?

The 2 types of dispensers also work differently, which is why it is essential to mention what kind of dispensers you’re looking at.

1. Bottled Water Dispenser

types of water dispensers

The bottled water dispenser is a simple device. The water is placed upside down on top, where there is a small hole where the mouth of the bottle fits. It is designed like this, so that gravity and vacuum pressure will fill the machine with water from the bottle, which then gets released to the cup or glass when you press the faucet or spigot. As the water comes out, the air is also let inside.

Because there is a valve in your water dispenser, it stops the water from flooding the machine. The rest of the water stays in the bottle, replacing the water from the tank when someone fills their glass. The tank has a device that either heats or cools the water consistently so that it has the right temperature when anyone needs it. Thus, it needs to be plugged in the entire time, and it will consume electricity when it regularly heats or cools the water.

These dispensers do not have any filters built-in because the water in the bottles is already filtered. Instead, the main purpose is to warm or cool the water and to distribute it to glasses or mugs. Because it can deliver at the desired temperatures, it is even a better option compared to small bottled water.

Servicing these machines is easy and uncomplicated since most of the issues involve heating or cooling functions.

2. Point of Use (POU) Water Dispenser

As mentioned above, these dispensers are not mobile and instead, are mounted to any wall and receive water from the taps. This is a common option in places where the tap water is drinkable. The huge advantage of this kind of dispenser is that there is no need to place huge water bottles (which are heavy) when it runs out.

These dispensers work by first heating the water all the way to 95 degrees,before it is passed through 2 carbon filters. Because the water is heated, no extra filtration is needed. But for cold water, it is filtered through 2 carbon-activated filtration systems and a UV light chamber to make it safe for consumption. Some models even offer an option to add CO2 to create sparkling water.

These dispensers have different tanks for cold or hot water, each with either a heating or refrigerating system. It is also dispensed with the help of gravity so that when you open the tap, the water simply flows out with your desired temperature. Just like the bottled water dispensers, they use electricity in order to filter the water and to keep it at specific temperatures.


Does it make sense to keep a water dispenser at home or work? The simple answer is yes! While water can be boiled in a matter of minutes and ice cubes can be added to lukewarm water, these still require a few steps and some time before the desired temperature is reached. On the other hand, your water dispenser delivers exactly what you want when you open the tap. Plus, if you live in a place where the tap water is not drinkable, it is definitely the perfect alternative to water in throwaway (and usually unrecyclable) bottles.
