Hot water at your fingertips.
How often do you boil water for drinks or foods? If it's more than a few times a day, you deserve a Zojirushi water boiler. A water boiler is an appliance that boils water and keeps it warm. Unlike an electric kettle, its main feature is keeping water warm at various temperatures, so hot water is at the ready whenever you want a cup of tea, instant food, or even for culinary uses.

How do you use a Zojirushi water boiler?

How does a Zojirushi water boiler work?
All Zojirushi water boilers are MICOM or micro-computer controlled to make constant adjustments to the heater to maintain water temperature. VE or Vacuum-Electric hybrid models utilize a double-wall stainless steel vacuum sleeve around the water tank to reduce heat loss while keeping warm.
What makes a water boiler unique?
Water boilers are unique in that they're not designed to boil quickly like an electric kettle, but they will keep water hot at the temperature you want. This makes it ideal when brewing tea throughout the day, so you don't have to keep boiling water each time you want a drink. They also make dispensing easy, as there is no lifting to dispense.
Water tank is made of stainless steel, and most are nonstick coated to aid in the removal of scale buildup.
Makes it easy to see how much water is left. If it runs out? Don't worry! The heater will shut off to prevent boil-dry.
Dispense hot water at the touch of a button. No lifting or tilting required.
What is the right temperature for brewing tea?
Not all hot water is the same, especially when brewing tea. It's important to brew tea at the right temperature to get the most flavor or aroma, without some of the unwanted elements. See our guide below.
Whether a French press or a cone, no more waiting for water to boil and then cool to the right temperature.
