Instant hot water dispensers: Benefits and considerations

What are hot water dispensers and how they work?

Instant hot water dispensers are compact electric appliances that provide nearly boiling water on demand. They are designed to be installed on a countertop or sink and are typically connected to the cold water supply. The water is heated and stored in a small tank within the dispenser and can be dispensed through a spout or faucet.

Instant hot water dispensers are popular in households and workplaces where hot water is frequently needed for making hot beverages, cooking, or cleaning. Drinking plain hot water also has many benefits, according to experts.

Instant hot water dispensers are convenient, time-saving, and energy-efficient, as they only heat the amount of water needed instead of boiling an entire kettle or pot. These appliances use a heating element to preheat water to a temperature around 200 F and store it inside the tank before dispensing. To use them, simply fill the tank with water and plug the dispenser into an electrical outlet.

In addition to their basic function, some models offer adjustable temperature settings, water filtration, and safety features to prevent accidental burns or spills.

What to look for


Instant hot water dispensers come in a variety of designs, styles, and sizes to fit different needs and preferences. They can be installed under the sink or on the wall as built-in models, or placed on the countertop like electric kettles.

Built-in models often feature a single-touch, touchless, or manual tap faucet for dispensing hot water on demand, providing additional convenience and comfort.


More expensive instant hot water dispensers typically offer higher quality materials and construction, as well as a range of useful and convenient features, such as:

  • Temperature control settings to adjust the water temperature to your liking
  • Automatic shut-off features for added safety and energy efficiency
  • Warming function to keep hot water at a consistent temperature
  • Built-in water filtration systems to improve water quality and taste
  • Descaling options to remove mineral buildup and improve performance
  • Dechlorination systems to remove chlorine and other impurities
  • Timer built-in for scheduling hot water delivery
  • Digital displays and touch screens for easy operation and maintenance

The size of the heating element determines how quickly water is heated and delivered. Typically, it takes 5-10 minutes for the water to reach the set temperature.

Built-in hot water dispensers come with a small water storage tank, often installed under the sink, and a faucet for dispensing hot water at the pre-set temperature. You can choose from a traditional manual tap faucet, touch, or touchless models.

The tank capacity determines how much hot water can be dispensed before the tank needs to refill. Typical models can deliver approximately 40-60 cups of hot water per hour, but larger capacities are available at a higher cost.
