Key Features 

 

Glass Coated Element 

Scale and sediment build up on the surface of standard elements lead to premature 
failure. An A. O. Smith glass coated element helps to prevent scale formation on the 
element, extending the life of the element.   

 

 

Blue Diamond Glass Lining   

A. O. Smith water heaters come with special glass lined inner containers. This lining is 

achieved through a specialized fusion process carried out at 870ºC. Inner tanks are 

designed to pass the 100,000 cycle fatigue life test in accordance with relevant UL 

(Underwriters’ Laboratories) Standards. This makes our tanks one of the best inner 

containers, resistant to rust and scaling. 

 

Anode Rod Protection   

The tank has an anode rod system with a stainless core that is designed to protect the 
tank from corrosive elements. The system uses a special cathodic action to fight the 
corrosive elements, prolonging the life of the water heater.   

 

 

Safety Valve 

This water heater has a pressure safety valve. This valve is designed to automatically 
relieve and discharge water in case the pressure or temperature exceeds the preset 
limits.   

 

 

Thermal Cut Out 

The water heater employs a thermal cut out. In case any fault occurs and the water 

temperature exceeds the highest preset temperature (93°C), the switch rapidly cuts off the 
live and neutral line for user’s safety.
