Everything You Need to Know About Zojirushi Water Boilers

When it comes to brewing great-tasting tea and coffee, every drop counts. That’s why we’ve designed our Zojirushi water boilers for maximum efficiency and convenience so that you can have the hot water you need at the touch of a button. If you’re looking for a water boiler to add to your home or office, or want to know more about our lineup, look no further! In today’s guide, we’ll go through all of our water boiler models and their functions – from Café Drip Mode to Quick Temp Modes – to help you choose the best hot water heater for you.

The Basics

First, let’s go through some basics so that you can understand how our hot water heaters are labeled and categorized:

  • There are three main categories of our water boilers: the Vacuum-Electric Hybrid (VE Hybrid), Micom, and our Commercial size water boiler. We will go through each of these models in detail below.
  • You will notice that each product will have a number at the end of it. This denotes the water boiler capacity: 30 stands for 3 liters, 40 is for 4 liters, 50 for 5 liters, and so on. If you are looking for a smaller capacity hot water dispenser, you may want to look for a product ending in “30,” if you’re looking for something large, take a look at our products ending in “50.”

The Features

Now we’d like to show you all of the features that make our water boilers uniquely Zojirushi. All of our hot water heaters will include the below, no matter the model:

  • Micom Technology: a computerized technology that keeps water at a select temperature for as long as it is plugged in.
  • Safety Auto Shut-off: A function that prevents overheating when no more water is inside or when the lid is open.
  • Descaling Mode: This important function will help you keep your water boiler sparkling clean, free of mineral accumulation. Just make sure you use it often with citric acid.
  • Unique dispense mechanism: All our hot water heaters do not require lifting or pouring – just a one-touch or pump dispense!
  • Other features include:
    • Reboil mode
    • Dechlorinate Mode
    • Convenient lock/unlock feature prevents accidental dispensing
    • Sturdy fold-down handle for easy transport

That’s a lot of great features, right? Now, let’s get into the different models to see which hot water dispenser is best for you.

The Models

First, we’d like to introduce you to the Vacuum-Electric Hybrid (VE Hybrid). VE Hybrid models use less electricity to keep water warm and feature quick temp modes to reduce heating times and electricity. There are currently two VE models in our lineup:

    • Hi Channhu, many of our customers keep it on all day as long as they have water in it and don’t let it become empty. We recommend to unplug it if the unit will not be in use and to always keep up with the maintenance to ensure the product’s longevity. Please let us know if you have any questions!

  1. Hello, I am a little confused and need your help figuring out the differences between the commercial vs any of the rest, mainly the CV-JAC which I’ve read is your top of the line.
    I need it mainly for all day drinking warm water as well as herbal teas. Which would better fit for the purpose?
    Thanks a lot!!

    • Hi Yasmin, the commercial model water boiler will come with only 3 temperature settings, a thicker power cord meant to be used in commercial kitchens. The CV-JAC VE Hybrid is vacuum insulated which will keep the water at the keep warm temperature for much longer without the water boiler having to use the heater. This means that it will use less energy to keep it on. It also comes with 4 different temperature settings and a vacuum mode that will turn off the heater as soon as the water reaches the keep warm temperature and will rely on the vacuum insulation to keep the water warm.

      If you drink different types of tea that require different water temperatures, I would recommend of going with one our regular water boilers like the CD-NAC because it will be much quicker for the water boiler to change the keep warm temperature. The VE Hybrid will take a long time to have the water temperature lower if you had it at a high temperature for herbal teas and wanted to brew a green tea later. If you use the same temperature throughout the day, then the CV-JAC is the perfect option. As for the commercial one, if you are not using at a restaurant or business then it’s best to use the home use water boilers since they have more features and a longer warranty.

      Hope this is helpful! Let us know if you have any other questions!

  2. I brought a brand new water boiler From you, After a few uses,The water has a funny smell, I call your customer service, hoping to replace the unit,Your people told me the only solution is to return the unit and get refund,Do you have this quality issue? And why do you have such poor custom service?

    • Hello Charles, we appreciate you sharing your experience here. New products may have a little bit of a resinous scent but it will dissipate after a little while. The materials we use to make our products are thoroughly tested to ensure their safety and quality. The water boiler doesn’t have materials that will change the quality of the water used and it will not change the components or minerals found in the water. We unfortunately aren’t able to process exchanges at this time and are only able to process returns.

      We never hear about a new unit after being used a few times having any strange smells. We would highly recommend going with what our Customer Service Team recommends in order to resolve the issue.

    • Hi Steve, thank you for the feedback! This post was meant to point out the differences between the models and aside from our VE Hybrid models which come with the added vacuum insulation, the differences can really boil down to aesthetics and capacity. All water boilers will boil the water and keep it at the selected keep warm temperature. The vacuum insulated models will use less electricity in comparison with the others. Our CW-PZC22/30 has a manual dispensing mechanism and only one keep warm setting. When choosing a water boiler we would recommend deciding whether you’d like vacuum insulation or not, color you’d like to have, and capacity. All of our water boilers are made with quality materials and will have the same basic functions so we are sure that you will love it no matter which one you choose!

      We hope this helps! Let us know if you have any other questions.

  3. Reference to CD-LFC40. Can I unplug the boiler and add more water or do I have to dump out the water and refill again? Also, can I unplug the boiler at night and plug it back in the morning without changing the water?

    • Hi Kelvin, if the water boiler’s water level is running low, we recommend refilling it even while it’s plugged in. That way, the water boiler will start heating the water for you right away. While you can keep hot water overnight in the water boiler while it’s in use, typically, you want to empty it if you aren’t going to keep the water boiler on. Now, you can keep water inside the water boiler to use the next day. This is how you would use the timer function, the water boiler would be filled with water and once the timer is set, it will have your water hot and ready for you by the time you wake up in the morning.

      Hope this helps!

  4. this is a terrible overview. the only meaningful differences I can tell is the unit color, capacity and the cafe drip mode.

  5. Hello,
    I recently purchased the JAC 50, and I love it!

    My question:
    I would like to use the timer function. How do set it up that when the unit ‘wakes up’ in 8 hours, it heats the water directly to 175 degrees? I want to avoid having the water go to full 212 boil upon start-up (I use filtered water). Thank you!

    • Hi Brian, you will first want to set the keep warm temperature and set up the quick temp mode. The quick temp mode can be set by pressing the reboil button. The light on the button will turn on. Then, you want to set up timer function by pressing the timer button until you see 8 H appear on the screen, and it will be set. YOu should hear a melody when the timer is activated. How to set up the quick temp and timer is on page 14 of your manual or you can give us a call at 1-800-733-6270 and a customer service representative will be happy to walk you through setting up your water boiler.

    • Hi Betty, usually, you will press and hold the UNLOCK button and it will change the melody to beeps. Our Customer Service Team can also help you over the phone, walking you through the melody change if you would like, please call 1-800-733-6270 and they will be happy to help!

  6. I just bought a 5L CD-LCQ. As with my previous kettle, I unplug and turn off the power supply after I have boiled a fresh pot of water, and will turn the power back on to reheat it to 60/80 deg c if I need hot water again, say every 1-2 hours later. However, the CD-LCQ always reboils the cooled water all the way to 100 deg. I understand this is a product feature, but it is not energy- (or time-) efficient at all, compared to using electricity only as and when needed. Is there any way to re-warm the water without reboiling after being unplugged, or must the pot be perpetually plugged in and powered on (which consumes a lot of energy as we do not need hot water continuously)? Appreciate your advice

    • Hi Esther, our CD-LCC water boiler will keep water at the set temperature while it’s plugged in. However, if you unplug it and replug it, it will restart the process and heat up the water to boiling point and then lower it to the set keep warm temperature. The only work around would be to use the Quick Temp mode to have it heat up the water to the keep warm temperature. Our water boilers will keep water at the set keep warm temperature while in use, so you don’t have to wait and you can dispense it at the touch of a button. This means that it will use some electricity throughout the day while it’s functioning. The intended use is a little different than that of a kettle. I hope this helps!

  7. Hello,

    Is there an way to reset the settings on the boiler? Our boiler is acting weird, and the last I saw was it was boiling and went to 6hr timer and shut itself off.We have model CD-WBC40.
