Blue Diamond® Glass-Lined Tank: The HSE-SFS is engineered with A.O. Smith’s signature Blue Diamond® technology, providing twice the corrosion resistance compared to industry standards. This specialized glass coating is fused to the inner tank, protecting it against the harshest hard water conditions and ensuring a significantly longer tank life. Because of this robust build, the unit comes with an extended warranty, offering you long-term reliability and peace of mind.

High Energy Efficiency & Performance: Designed to be as easy on your wallet as it is on the environment, this model features superior BEE 5-star rated energy efficiency. The high-density PUF insulation traps heat effectively, reducing standing heat loss and ensuring that the water stays hot for much longer without drawing extra power. This mechanical series offers a straightforward, reliable interface that delivers consistent performance day after day.

Customizable Aesthetics with Color Panels: Unlike standard heaters, the HSE-SFS allows you to match your appliance to your bathroom decor. While the standard fitment comes in a white body with a red panel or an ivory body with a red brick panel, you have the option to customize the look. Customers who order the HSE-SFS Mechanical series can upgrade their aesthetic with optional color panels for just Rs. 200/- (available for 6 and 10-litre capacities).
