Features

SAFETY SHUT OFF: The combustion shut off device is the primary safety feature of the water heater. When the combustion chamber goes too high (>260° C), the glass bulb breaks causing the damper rod pops out to close the air supply and extinguish the flame. Effectively prevent fire, gas leakage or other dangerous accidents.
DON'T WORRY: It greatly reduces the possibility of water heater accidents, and there is no need to worry about it in hot showers and many other daily activities. TRD will win your heart and protect your water heater from the impact of accidents.
