Zojirushi Hybrid Water Boiler & Warmer

I have been reading other reviewers experiences, with some being very unfavorable, so I thought I would share our experience. We purchased our current 4.2 liter unit in December of 2017 (it's January 2026 now). It is the CV-DCC40XT and according to the lid, it was made in Japan. It is still going strong with no issues to the seals, boiler or plastic parts. It is plugged in all day every day so the water is always ready to go. When we remember, we will put it to sleep at night, but that probably only happens about half the time. (It should go without saying, but never, ever let this unit run out of water.) We clean the unit on a regular basis. What that means is when the interior of the pot gets a white calcium coating on it, it gets cleaned. You can see it building up against the grey color of the pot. Mind you, it's not a little amount, but it's also not a heavy crust. At this point it gets cleaned with citric acid using the machine's cleaning cycle. Depending on water hardness, the buildup can occur much more frequently than in a softer water environment. In fact, at our previous house, we would occasionally clean it twice in a row due to the very hard water buildup. When done cleaning, it should look like new. It's not hard work, you just need to run through the cleaning cycle and wait. We purchase citric acid in 5lb bags (which is way cheaper than the little packets) and use 2 tbsp for each cycle. We may clean it once a month or in the soft water environment of our current house, it will get cleaned every 4 months. It just depends on the calcium buildup. In regards to some of the horror stories I've read in some these reviews, it's hard to know the conditions in which the unit is being used. It's obviously also possible that the quality of the product's materials has changed. When I did a search on google, calcium can have negative effects on plastic. I have not experienced this. When I opened the lid on our unit today to see if there were issues, everything looked brand new. In summary, we love this unit and it's a workhorse. Keep it clean with citric acid and never let it run out of water. When our current unit dies, we will probably buy another one. Hopefully, it will work just as well and the manufacturer will not cheapen the quality of materials.

This thing is awesome! Four liters of boiling hot water (at my choice of temperature: 208, 195, 175, or 260 degrees F) always ready to dispense on my countertop. It heats up very fast to boil the water then it lets it cool to your selected temperature and keeps it there. It has insulated walls for energy efficiency. A quiet pump quickly dispenses a stream of hot water or you can remove the lid and just tip and pour out larger quantities. I use this all the time to make tea, hot soup, or anything else that calls for boiling hot water. Zojirushi is known for making top-quality reliable appliances and this water boiler is no exception! It has a self-cleaning mode and the directions tell you to add their cleaning powder (sold separately) and run the self-cleaning cycle to descale the inside. But just use citric acid crystals instead of their proprietary powder--that's the same thing, but much cheaper. And it really works! Add the crystals, run the cleaning cycle, dump out and rinse--all the lime scale is gone! A water boiler is a fantastically handy kitchen appliance and this one is the top model. It's pricier than others but remember, you get what you pay for. I had a cheap one previously that died after a couple years. This one is four years old and looks and works like the day I got it. It makes a fantastic gift, too--perfect for newlyweds, college students, anyone!

After 6 years and 4 months, I had to finally replace this. It would have lasted longer if I had cleaned it more often, I am certain. But I chose the same model and everything I wrote before remains the same. Maybe one of my top 10 purchases. Worth every single penny for reliable hot water any time. The new one should arrive today and waiting for water to boil has been very noticeable. It’s a small thing, but it saves time. Who knew how big a difference a simple, high quality appliance like this could make to our family’s quality of life! Can’t wait for the replacement to arrive today so my wife can make her herbal tea right before bed and I can wake up and just make coffee. One of my top 20 purchases of all time. We drink a lot of coffee and tea in my house and had used a Keurig for a long time. Our Keurigs, though, never seemed to make it past a year and got noisier and noisier over time. This, however, is quiet. The loudest sound on it is the beeps from the buttons (after I turned off the alarm that lets you know the water has reached the right temperature). While I would prefer it had an option to make no sounds, it has been so great I have to give it 5 stars. We keep the temperature at 195 and it has been perfect for teas and coffee in a French Press. I also use it to get a quick start on cooking. One BIG note is that by default, whenever you add more water, it wants to heat the water to boiling and then let the water temperature go down to whatever temperature you have set. Luckily, though, there is a "Quick Temp" option which turns this off. I only boil the water once every week or so to make sure things are sterile inside. Without the "Quick Temp" feature, though, we would not be able to leave it on our counter under a cabinet because it would steam and damage the cabinet finish. So just make sure you have open space for the steam OR you use the "Quick Temp" feature to prevent the steam. Zojirushi as a brand now sits alongside my KitchenAid mixer as far as my loyalty and willingness to recommend unequivocally to anyone.

It is our second one. We use it daily a few times per week to have a cup of tea or when just need quickly add boiling water while cooking. The hardest thing of cause is to make sure someone fill it with water. The first boiler served us over 3-4 years, so we expect this one to be as good. Size is great. Heats quickly. Lid functionality is good. Quality material for sure. Overall we happy, and I would definitely recommend over a electric teapot.

We had a different thermal water boiler for about ten years, and found it extremely handy. I had been strongly tempted to get a Zojirushi before, but wasn't sure how much we would use it. In fact, we got quite spoiled, always having water available to make hot beverages, and had to refill it at least once a day, in addition to at bedtime, as we're both retired now, so we knew we wanted one with a larger volume. I also wanted it to be tall enough that I could fit one of my Zojirushi tea carriers under the spout. This size seemed ideal, and so far it's met and exceeded all of our expectations. First, it comes up to temperature amazingly quickly if you set it to do so. It will also come to temperature as slowly as you want if you fill it before going to bed, and set the timer; and you can set it to thermal, and let the vacuum insulation keep the water hot. The water gauge is easy to read once you get the hang of it. We have only needed to refill it once except at bedtime, although we're both getting hot beverages throughout the day and evening. The thermostat reading verifies that it has always kept the water at the chosen temperature. We love the tunes it plays, which could be changed to simple beeps or turned off, but as my husband says, it's a cheerful little thing, and we enjoy hearing it. I think the only feature we haven't used is the self-cleaning cycle, as that hasn't been needed yet. My only complaint is that 185ºF, which is the best choice for a few of my teas, is not one of the temperature selections; however, that is attainable by cooling 195ºF water through pouring from another vessel to my teapot, so that is really not a major concern. However, I've also discovered that if I keep the water boiler set to 175ºF, I can then set it to 195ºF and choose Quick Temp to bring it up to 185ºF amazingly rapidly, then reset it to 175ºF. It's really quite amazing how quickly this heats water. Thank you for reading my review. I hope you found it helpful.

I bought this boiler December 2024. I had gone through another electric kettle. My husband wanted an electric kettle NOT made in China. Could not find one. This Zojirushi is made in Japan and it rules! Love it. Heats the water fast and keeps it warm. Very easy and quick to reboil the water. Easy to clean and remove the scale. Highly recommend. The spout makes it great for pour over coffee pot and a cup of tea.

If you’re looking for a premium, reliable way to keep hot water ready all day for tea, coffee, or cooking, the Zojirushi Hybrid Water Boiler & Warmer is a standout appliance. The Zojirushi Hybrid Water Boiler & Warmer features a sleek, compact design that fits easily on a kitchen counter without taking up too much space. The orange LCD control panel is intuitive, displaying the actual water temperature at all times, and the wide water level window with a red ball indicator makes it easy to see when it’s time to refill. This boiler uses advanced vacuum-electric (VE) hybrid technology to efficiently heat and maintain water at four preset temperatures (160°F, 175°F, 195°F, 208°F), ideal for different types of tea and hot beverages. The optional Quick Temp mode is a major convenience, letting you reach 160°F, 175°F, or 195°F without boiling first, which saves time and energy. Once set, the machine keeps water at your chosen temperature all day with minimal electricity use, so hot water is always ready when you need it. The insulated design means it doesn’t use much electricity to maintain heat, and the handle makes it easy to carry for refilling. The Zojirushi Hybrid Water Boiler & Warmer is a game-changer for anyone who wants instant access to hot water, multiple temperature options, and a hassle-free, energy-efficient appliance. It’s an investment, but the convenience, reliability, and thoughtful features make it well worth it for daily use.

I love this hot water heater! After having an older model for 14 years (as shown in my photo) it was time for an upgrade and I’m very happy with it! The color goes well with my counter top too. I love that it has the quick temp so that I can reach my preferred temp after refilling or power outage, etc without having to boil it again. The unit IS very expensive and I almost went with a different brand. But I was so happy with my old unit that I didn’t want to take a chance on an inferior version. I highly recommend you get the brand’s tank cleaner because it’s worth it! The other thing I love about this newer model is the vacuum setting! I can set it to vacuum and it’ll keep it fairly hot for a long time. I had it set to 195 when I went to bed one night, and I woke up the next morning it had only gone down to 150. Pressing the Quick Temp got it back to 195 in just a few minutes. Plus, the way the lid is made with the vacuum seal, it keeps the water from running down the back when you open it (unlike the older model). The only thing I have a gripe about is the lettering on the buttons. I’m not sure why they couldn’t make the lettering fit on the buttons. It looks kind of d u m b. The older model did not have this issue. It’s a little detail I wish they’d paid more attention to but I still love it. I need to mention that we use this hot water heater for everything - oatmeal, tea, cocoa, instant coffee, instant potatoes, pasta (just finish cooking in the microwave for about 4 minutes), ramen noodles, anytime a recipe calls for hot or boiling water. Did I mention that I love it? LOL!
