This video is going to answer the following question:
Q: Why did they remove the outer coils that were there to reduce water temperature output? Does this new model still cools the water to 90 degrees?
A: They didn’t remove the outer coils; instead, they integrated the coils into the iron cylinder since stainless steel does not require cooling. As a result, you'll notice that in the latest version, the iron cylinder is thicker than in the old version.
I actually asked them the same question, and interestingly, the new design offers a significant improvement. In practice, they found that the temperature can now be maintained at consistently higher levels, around 90°C. In contrast, the old version had less stability, with temperatures fluctuating between 78°C and 85°C.
Another benefit they discovered is that the outer coils tend to accumulate limescale over long-term use, making them difficult to clean. By integrating the outer coils into the iron cylinder, we can significantly reduce the hassle caused by limescale, achieving a self-cleaning effect and extending the lifespan of the kettle.
