We often hear the age-old advice that we should drink at least eight glasses of fresh water every day to maintain good health. However, many people lead busy lives that do not allow them the time to even boil water. Nevertheless, a healthy adult does need to consume around two liters of water daily, depending on their level of activity and the weather conditions. Many people find that tap water, even if boiled in a clean electric kettle, has an unpleasant taste and they are reluctant to drink it. If you continuously drink water from an electric kettle over an extended period, you are essentially drinking re-boiled and stagnant water. Studies have shown that regularly drinking repeatedly re-heated water in this manner could contribute to kidney stones developing in the body. Additionally, the electric kettle can accumulate scale and bacteria. As more people are paying attention to the quality of their drinking water and the way they consume it, home water dispensers have become extremely popular in recent years.

As the name implies, it makes hot water instantly with no waiting and no repeated re-boiling. This smart water dispenser is convenient if you need to make different drinks often and want different hot water temperature settings. It saves boiling the water and having to wait for it to cool down. Most instant hot water dispensers on the market have filtering, instant drinking and instant hot functions.

1. The hot and cold water are separate. It comes with an instant heating function so there is no mixing of cold water and hot water.
2. Some models have no inner tank and therefore there is no accumulation of scale or bacteria. You can simply pour white vinegar or lemon juice into the dispenser for easy cleaning and maintenance.
3. Hot water is ready for use with different water temperature settings. It does not require warming up and therefore saves energy and electricity.
4. Most instant hot water dispensers come with safety features such as auto power-off when there is no water. You can also adjust the temperature of the hot water.

1. Dimensions:
instant hot water dispensers are mainly divided into "bottom loading" and "tabletop" types. Decide which type is suitable according to the space you have available and where you want to put your dispenser.
2. Water filtration and purification function:
check what type of filter the dispenser uses and whether there is a stable supply of filters for replacement before buying.
3. Heating function:
some water dispensers use instant heating technology to release hot water in three seconds. The main advantage of this type is that you don’t have to wait for the water to boil.
4. Temperature settings: :
Most instant water dispensers are equipped with three settings: room temperature, warm water and boiling water. Otherwise, choose a water dispenser that offers different water temperature settings.
5. Trustworthy brand:
Because of food safety concerns, certification is very important. Most major water dispenser brands are made from nationally certified food-grade materials with no heavy metal contaminants, so good brands play an important role in choosing a water dispenser. The water filter is also important. If you buy a water dispenser from an unknown brand, the source of its filter may be questionable and could be detrimental to your health.
