Withdigital constant watersetting function the water temperature will remain constant
in the degree you set.
The fuel efficiency because of your device can operate constantly at set water
temperature, fuel efficiency decreases.
By the automatic water controlled on/off system, when the water tap is turn on, the
water heater will automatically operate and the hot water flow will be provided. When
the water valve is turn off, the water flow will stop and water heating will stop.
Operation with low water pressure function: it does not affect by the low water
pressure that occurs in the high apartment flats.
The temperature control adjustment buttons make for users easy to obtain different
water temperature that they desire Provide consumers to obtain different water
temperatures that they desire.
By the high temperature safety system, in case of the water getting hotter than it is
needed, the gas will be cut off automatically and the damage of the water heater will
be prevented. The flame instability is prevented and the water is cooled after the
flame is off with the features of blowing inside the water heater before the ignition (air
fan blows air for 2~4 seconds before ignition) and the blowing after service (air fan
will go on blowing air for 10 seconds after the water stops and the flame is off).
Safe and reliable design of the combustion system, Air is taken from outside by the
fan for the purpose of providing combustion and discharged exhaust gas to outside
again which is occurred after combustion. By the system of continuous electronic
ignition, 100% success is achieved in ignition.
Multi -purpose safety system. Even if the power is supplied to the water heater again
in power failure, fan failure, the blocking of the waste gas pipe or strong reverse wind
blowing the gas will be automatically cut and the automatic ignition system will be
disabled. In this case the water heater can restarted again after negative conditions
that prevent operation of heater is disappeared.
