The Best Hot Water Dispenser: Our Selection

Buying and evaluation criteria for hot water dispensers

There are two types of hot water dispensers that differ fundamentally.

Instant hot water dispensers heat the water the moment it is needed and large container hot water dispensers heat and hold a lot of water at the desired temperature.

Material

Most hot water dispensers are made of stainless steel and plastic. When buying, make sure that the water does not come into contact with the plastic, but only with the stainless steel. This way you can avoid microplastics and other impurities in the boiling water.

Size and capacity

Instant hot water dispensers typically have a tank with a capacity of 2 to 3 litres. Most large container hot water dispensers have tanks ranging in size from 20 to 30 litres, and some even hold up to 70 litres.

The difference, however, is that the water in large container hot water dispensers must first be heated for a longer period of time. This takes several minutes or even over an hour, depending on the filling quantity. Instant hot water dispensers only heat part of the water in the tank when it is used.

Adjustability of the temperature

The temperature can be adjusted with pinpoint accuracy for both types of hot water. Since instant hot water dispensers heat the water just before use, you can set the temperature at the touch of a button. The options usually range from 40 to 100 degrees and can be selected in increments of 10.

Power consumption and performance

The power consumption is related to the output. It is expressed in watts and ranges from 500 to 3000 watts. The higher the number, the faster the water can be heated, but this also increases the power consumption.

Instant hot water dispensers have the highest power because they heat the water in seconds. In this sense, they consume more electricity, but only for a few seconds. This makes them very energy-efficient overall.

Large container hot water dispensers are in the lower to medium wattage range. For this reason, and also because of the larger amount of water, they take longer to heat. Moreover, keeping the water warm costs additional energy.

Suitability for mulled wine, cocoa & punch

Instant hot water dispensers are not suitable for ready-made drinks. They only prepare hot water to make the desired drink afterwards. Examples are tea, instant coffee, instant cocoa. You should never put anything other than water in the tank of your instant hot water dispenser, as sugary drinks will gum up the electronics.

The situation is different with large container hot water dispensers. You can fill them with mulled wine, ready-made cocoa and punch. The heating works in such a way that nothing sticks.

Extras

Higher-quality models often have the following extras:

  • Display: A display not only completes the look of a hot water dispenser, but is also very useful. The desired temperature and quantity can always be set on it, and maintenance information can also be displayed. Many hot water dispensers with a display are also touch-controlled.
  • Water filter: Water filters ensure perfect water quality. They usually consist of an ion exchanger and coarse particle, fine particle and activated carbon filters. They reduce chlorine and organic substances, as well as limescale and metals such as lead, cadmium and mercury. Natural minerals and trace elements in the water are preserved. Water filters need to be replaced regularly. You can buy them in packs of 3 to 5, which will then filter the water reliably for a longer period of time.
  • Child safety lock: A child safety lock is essential if you have children in the household. There is a risk that they will press a button and suddenly hot water will run over their hands. The child safety lock closes the pump and prevents water from escaping. Most instant hot water dispensers have this feature.
  • Automatic descaling programme: To prevent the hot water dispenser from calcifying after some time, many models have an automatic descaling programme. This flushes and cleans the pipes and lines of the hot water dispenser after some time. This prevents calcification and the resulting bad taste of water.

Which model of hot water dispenser you finally choose depends on several criteria.

Guide: Questions you should ask yourself before buying a hot water dispenser

In this section we answer the most frequently asked questions about hot water dispensers.

What are hot water dispensers?

A hot water dispenser is a device that pours hot water into a cup or glass at the touch of a button. There are two different types: Instant hot water dispensers and large container hot water dispensers. The difference lies in the timing of the heating of the water and the size of the water tank.

Instant hot water dispensers heat the amount of water you need at the moment you press the button. They are elegantly designed and usually the size of an average kitchen appliance.

What is special about hot water dispensers and what advantages do they offer?

A hot water dispenser prepares hot water at the desired temperature in seconds. You can conveniently set the temperature via the dispensing button on instant hot water dispensers or via the controller on large container hot water dispensers.

There are two different types of hot water dispensers:

Large container hot water dispensers

Large container hot water dispensers can have a capacity of up to 70 litres and keep the water at the desired temperature once heated. So they are perfect for events and catering. They are also suitable for coffee, hot cocoa and mulled wine. But just then they need to be cleaned regularly and that can only be done manually.

  • Water stays warm all the time
  • Also suitable for coffee, hot cocoa and mulled wine

Who are hot water dispensers suitable for?

Instant hot water dispensers are suitable for

  • Tea lovers
  • Instant coffee drinkers
  • Lovers of instant noodles and soups
  • Mothers and fathers who prepare baby food

people who do not want to wait so long for the water to heat up. Hot water dispensers are also ideal for experienced tea drinkers who prefer to pour 80°C water over green tea, as they allow the temperature to be adjusted.

Large container hot water dispensers are very suitable for catering and events as they have a high capacity. All the water is kept at a constant temperature all the time. Large container hot water dispensers are also the best solution for other drinks, for example coffee, mulled wine and hot cocoa.

How are hot water dispensers descaled?

Instant hot water dispensers often have an automatic descaling programme.

You will always find the appropriate descaling instructions for your appliance in the enclosed operating instructions.

Large container hot water dispensers do not have a descaling programme and must be cleaned and descaled by hand. We recommend pipe cleaners and special cleaning agents for this purpose.

Are there hot water dispensers for mulled wine?

Large container hot water dispensers are not only suitable for hot water, but also for mulled wine, coffee, hot cocoa, punch and many other possibilities.

They are therefore ideally suited for events, gastronomy and Christmas markets.

Which is better for me? A hot water dispenser or a kettle?

The answer to this question depends on how often and in what quantity you need hot water. If you need hot water occasionally, a kettle is enough for you. If you need a lot of hot water often, a large container hot water dispenser might be right for you.

Are you a tea drinker and make yourself a cup of tea several times a day? Then an instant hot water dispenser is better for you. With it, you don't have to wait a long time each time and only heat the amount of water you need. This saves time and electricity. However, if you are not prepared to spend a lot of money on a hot water dispenser, we recommend a good old-fashioned kettle.

How much do hot water dispensers cost?

Both types of hot water dispensers have their own price range.

Type Price range
Instant hot water dispensers From 50 to 150 euros
Large container hot water dispenser From 40 to 200 Euro

For instant hot water dispensers, the price range refers to common models. There are also luxury models that can cost up to 2000 euros.

What are the alternatives to hot water dispensers?

If after reading this article you decide that a hot water dispenser is not right for you after all, there are still the following alternatives:

Name Description
Kettle It takes longer to boil water with a kettle than with a hot water dispenser. Also, the temperature cannot be adjusted precisely. On the other hand, kettles usually cost less than 20 euros. In addition, a kettle is not so big and you can store it more easily in a cupboard.
Tap with instantaneous water heater A tap with instantaneous water heater is installed in the sink instead of a normal tap. The water temperature is adjustable up to 100°C. It can even supply carbonated water. Unfortunately, such taps with instantaneous water heaters are very expensive and cost around 2000 euros.

So there are definitely alternatives, but hot water dispensers score points over them in many areas.
