* Blue Diamond Glass Lining : Blue Diamond technology increases the life of the inner tank. The lining is stronger and more corrosion resistant than any other in the industry.
* Glass coated heating element : Scale and sediment build-up on the surface of the element can lead to premature failure. A. O. Smith Glass Coating helps to prevent scale formation and extends the life of the heating element.
* BEE 5 Star rating. One of the most energy efficient Water Heater
* Digital Control : The LED displays electricity consumed, set temperature, actual temperature, timer etc. The user can select the set temperature within the range of 25°C to 75°C. This water heater can retain the set information for 72 hours, even in power off condition. (Only for HSE-SFS-015 & 025 Litres models.)
* Temperature Control Knob : The temperature control knob allows you to set the temperature precisely between 25 Degree C and 75 Degree C. (Only for HSE-SFS-006 & 010 Litres models.)
* Anode Rod : The tank has an anode rod which has stainless steel core that is designed to protect the tank from corrosive elements. The anode rod uses a special cathodic action to fight these elements and thus prolong the life of the water heater.
* Thermal Cutout : If the water temperature exceeds the highest preset level, the thermal cutout cuts off the power supply to assure safety.
* Safety Valve : The safety valve is designed to automatically relieve pressure and discharge water, in case the pressure overshoots the preset limits.
