Sen Series Water Heater Design.

Aptly named Sen, which means ‘line’ in Japanese.

Rinnai Sen series is inspired by the beautiful flowing water lines on karesansui (Zen rock garden - 枯山水) where water is symbolized by sand.

The sleek, elegant and parallel lines are aesthetically pleasing and calming to beyond, making shower a great retreat from the bustling world for the mind and body.
