Challenges
Balancing water storage capacity and perceived volume in electric water heaters, while providing users with a more intuitive and user-friendly operational experience.

Research & Insights
Double-tank water heaters represent a new innovative platform in its early adoption phase. Their prominent product features—compact size, high power output, low energy consumption, and energy efficiency—reflect the future direction of water heater development.


Solution
The double-tank structure reduces the perceived volume of the electric water heater, making it appear slimmer. We designed a more intuitive, human-centered user interface (UI) for the double-tank heater, centralizing all display information within an eye-catching decorative ring. The status of each tank can be displayed independently.
