Description
Experience reliable, Electric Storage Water Heater with Piano’s patented heating technology.
Piano’s electric water heater combines intelligent engineering with advanced safety and refined design. Its gradient heating system uses four-point sensing to drive the heating elements in stages, ensuring uniform heating without dead zones and enabling fast hot-water recovery. The electronic magnesium anode provides clean, long-lasting corrosion protection for the tank, while a flow-triggered power-off mechanism enhances safety by cutting electricity the moment hot water is detected at the outlet. With WiFi smart control, wireless remote operation, and an intuitive onboard interface, users enjoy flexible and convenient control options. A multi-layer safety system guards against overheating, dry burning, overpressure, and electrical risks. Finished with a curved PMMA panel and an aluminum-alloy frame, the unit delivers both high performance and a premium aesthetic that elevates any modern bathroom.
