Other Safety Features

Advanced Water Sensor
This gas water heater comes with an advanced water sensor which ensures
that sufficient water is flowing through the heat exchanger during operation.
This will avoid dry firing and increases the life of water heater.
Power Input Stabilization
This gas water heater has an in-built power stabilisation circuit to stabilise
input voltage fluctuations.
High Temperature Limit Protection Switch
This gas water heater employs a high temperature limit protection switch. In
case any fault occurs and the water temperature exceeds the highest preset
temperature, then the water heater is switched off by cutting off the gas
supply thus ensuring safety.
25 Minutes Timer (Child Lock)
If this gas water heater is left unattended or used in ON condition for more
than 25 minutes, then the timer cuts off the gas supply and the ignition to
ensure safety & avoid wastage of natural gas.

Well Built to Last Long

Corrosion Resistant (Oxygen free copper exchanger)
The heat exchanger transmits the heat produced by burning gas to water. This
gas water heater has a unique corrosion protection design in the heat
exchanger, further the heat exchanger is made from oxygen free copper which
offers extended life for heat exchanger. (Most competitor gas water heaters
use a lead or a tin coating to the copper heat exchanger. However, the coating
may fall off at high temperatures exposing the copper in the heat exchanger
to corrosion and lowering the product life).
