Description
Hot Water in Seconds. 2× Corrosion Resistance.
Blue Diamond Glass Lining · Long-Life Anode Rod · 5-Year Tank Warranty.
Sized for the jobs that don't need a storage geyser — washing hands and face on a cold morning, kitchen sink duty, a quick shave · Blue Diamond glass-lined tank engineered for twice the corrosion resistance · anode rod with 2× lifespan even in hard water · double protection from a thermal cut-out and a multi-function safety valve · compact enough to sit above almost any sink
A water heater doesn't usually fail because the electrics stop working — it fails because the tank corrodes and starts to leak. That's why the tank lining is the specification that actually decides how long the unit lasts, and it's where AO Smith concentrates its engineering. The Blue Diamond glass lining is fused to the inner tank to deliver twice the corrosion resistance of a standard lining, and behind it a long-life anode rod with 2× the lifespan sacrifices itself to protect the steel — even in the hard water most of Delhi NCR runs on. That combination is exactly what makes a 5-year tank warranty possible on a unit this size.
Blue Diamond glass lining and the anode rod — how AO Smith protects a tank
Every water heater tank is under continuous chemical attack: hot water plus dissolved minerals is a genuinely aggressive environment, and Delhi's hard water accelerates it considerably. AO Smith's answer works on two fronts. The Blue Diamond glass lining is fused onto the inner tank as a barrier between water and steel, rated at twice the corrosion resistance of standard linings. Behind it, the anode rod does the clever part — it's deliberately made of a metal that corrodes in preference to the tank, so the chemistry attacks the rod instead of the steel. A rod with 2× the normal lifespan means that protection lasts far longer before it needs attention, which in hard-water areas is the difference between a heater that lasts three years and one that lasts a decade.
Double protection — a thermal cut-out and a multi-function safety valve
A water heater combines electricity, pressure and heat in a small metal cylinder mounted on your bathroom wall, so the safety engineering isn't a bonus feature — it's the reason you buy a serious brand. This unit carries two independent protections. The thermal cut-out disconnects power if the temperature climbs beyond safe limits, guarding against overheating and dry-running. The multi-function safety valve handles the other half of the problem, relieving excess pressure before it can stress the tank. Two different failure modes, two separate defences — which is what allows you to leave it switched on without thinking about it.

Double Protection
Thermal cut-out plus multi-function safety valve, guarding heat and pressure
✨ At a glance
At 23.6 × 22.8 × 31.7 cm and 5.58 kg, it mounts neatly above a basin or kitchen sink where a 15 or 25 litre storage geyser simply wouldn't fit.
An instant geyser heats water as you need it rather than keeping a full tank hot all day — so there's no standing heat loss, no waiting for a tank to warm up, and no electricity spent heating water nobody uses.
A clean white body small enough to mount above a basin or sink without dominating the wall — it disappears into a bathroom or kitchen rather than announcing itself.
Five years of cover on the inner tank plus three years on the heating element — an unusually strong warranty in the instant-geyser segment, and a direct statement of confidence in the tank engineering.
