Experience reliable, Electric Storage Water Heater with Piano’s patented heating technology.

Piano’s electric storage water heater is engineered for durability, efficiency, and long-lasting performance. The enamel-lined tank is made from specialty steel and coated with imported FEROO ceramic powder, providing exceptional resistance to pressure, scale, corrosion, and high temperatures. A 50mm seamless high-density insulation layer ensures excellent heat retention with minimal temperature loss. The Ingle 840 heating element delivers fast, high-efficiency heating with strong resistance to oxidation and corrosion, while the gradient heating mode warms the tank evenly without dead zones, allowing rapid hot-water recovery. An electronic magnesium anode offers clean, residue-free corrosion protection for extended tank life. With an intelligent control system that learns usage habits and adapts to user needs, the heater provides a stable, reliable, and comfortable hot-water experience.
