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.
SAS has efficient Incoloy Heating Element that does not accumulate
calciferous deposits like copper.
Express Heat
(for SGS)
Save your time with the help of innovative Heating Element by heating
your water 33%
faster.
Temperature Control Knob
The Temperature Control Knob allows you to set the temperature
anywhere between 25ºC to 75ºC.
Long-Lasting Anode Rod
A customised alloy that works in different Water Conditions, protects
the tank and heating element from corrosion, has twice the lifespan
compared to a regular magnesium anode.
Multi-function Safety valve
The Multi-function Safety valve is designed to automatically relieve
pressure and discharge water in case the pressure overshoots the pre-set
limits.
Note:
A. O. Smith reserves the right to amend or modify the specifications and features
