Zojirushi CV-JAC50XB: A Game-Changing Upgrade for Effortless and Efficient Hot Water Management
We've recently upgraded to the Zojirushi CV-JAC50XB from the older CV-DCC50XT model and are thrilled with the improvements. The new C14 power inlet (the standard plug type used for many electronics) is a welcome change from the old magnetic connection, which was easy to lose. This model is slightly shorter, which surprisingly feels like it requires less frequent water refills, and the addition of a red ball in the water gauge is a clever, helpful touch.What impresses me the most is the reduced boiling time; it boils 5 litres of water roughly 10 minutes quicker than the CV-DCC50XT, in just about 30 minutes, which is a significant improvement. The matte finish on the upper lid not only looks sleek but is also more resistant to scratches, adding to the unit's durability. The design tweaks continue with the removal of Japanese characters on the lid lock, simplifying the interface.The LCD display, while not backlit, features an orange background that offers great contrast, making it easier to read without the concern of a backlight wearing out. Another practical feature is the handle that can now be parked at the back of the unit, securing it firmly in place.With a delay timer that can extend up to 16 hours before reboiling, this boiler is also perfect for those who frequently take weekend trips, ensuring you have hot water ready exactly when you need it, while further saving energy. However, I personally keep it set to maintain a constant temperature of 195°F at all times. Although only time will test its longevity, if it performs anything like our old model, which is still going strong after nearly a decade, we're in good hands. Remember, using filtered water is the key to maintaining these machines.In summary, the Zojirushi CV-JAC50XB is a fantastic upgrade filled with thoughtful improvements, combining functionality with durability. Highly recommended for anyone looking to enhance their kitchen with a reliable water boiler.

I actually purchased this to use when I’m canning and need hot water on demand rather than having to boil water on the stove. Forget that! I use it everyday for tea and so many other things. It has earned a permanent place on precious counter space! Love it. It holds a lot of water and it keeps it at a perfect temperature.

Love this water boiler. It's pricey, but you pay for quality and durability

I'll be honest: We didn't always use filtered water in our previous Zojirushi boiler, purchased in 2011, but it still lasted a good long time before the plastic in the lid finally degraded to the point of falling apart.

A particularly good feature of this boiler is its temperature control. While they promote it in terms of proper temperatures for varieties of tea (which I do drink a lot of), our main issue is we live at altitude. We *need* to set the boiler to less than 200F or else the water will boil off.

As far as energy savings go, our main interest isn't turning the unit on or off on a timer, but rather just how much power it uses while idle, and it really isn't much, not with the vacuum insulation. Anyway, here's hoping this new one lasts another decade or so.

I hesitated for a long time before splurging to get this boiler/heater. “Too expensive” I moaned. Finally, at holiday time I broke down and bought it. Just wow! I love it. I normally keep the temp set at 195* but when I want to make drip coffee, I can bump it up to 208* and it will be ready in just a few minutes. I especially like the “slow” output mode which allows you to slowly release the hot water over coffee grounds in a paper filter setup. We also consume a lot of green and dark teas, and this unit is always at the ready to brew a single or multiple cups. It is built like a tank, and is handsome to look at on the counter. Its footprint is not at all excessive either.

This is our second Zojirushi water pot. Our first one lasted us nine years and was still plugging along when we decided it was time for a new and larger pot. Great quality products. These are worth the money. When I am in the market for a replacement in another decade I will be buying another Zojirushi without question.

I absolutely love having hot water available without having to wait. Keeps the water hot all day. No complaints whatsoever.

I have been using traditional water boilers. Every time when I need hot water, I need to boil it once. This completely changed it and there's hot water whenever I need it.

Capacity is good for two people and it's really quite. The only drawback is that there's no scheduler to turn on and off everyday so that it's not wasting power at night. The provided energy saver function is a manual timer for some hours which is completely useless. To solve this problem, I use Kasa smart plug for automation. Additionally, it tracks the energy usage. I do not have the data for traditional water boiler, but I suppose it might potentially save energy. Even that's not the case, it's providing convenience with acceptable amount of power usage.

5.0 out of 5 stars Worth the Investment!

What can I say? This was an expensive investment but worth it for what you get! A lifetime (hopefully, and then some lol) of hot water! Super easy to maintain and use. Use it everyday. I love that it’s made in Japan because you know it’s made to last. I love that is has the vacuum insulation so you can turn off and unplug if needed. I love that it has different settings. Although, I do keep it at 208 degrees always. I love that there are different temperatures to choose from too. It takes maybe 10 to 15 mins to warm up from being super low or empty. It makes a cute ring to notify you of the same. Love it. Super happy with my purchase.

This unit has lower heat losses than other units, so in the long run the price difference is worth it. This unit dissipates about 24W when not in use, similar size (4L) usually dissipate 35W.

To me, the main benefit of this water boiler is that you get hot water all the time without having to wait for water to boil. Love it!
