1.4.3 DOMESTIC HOT WATER FUNCTION ( DHW )
The hot water function will also be mentioned as DHW.
The production of hot water takes place in a direct and instantaneous way: you will never be without hot water as long
as electric power, water and gas are guaranteed.
The appliance is equipped with a sensor that keeps the temperature of the supplied water under control: this is source
of high comfort and extreme safety for every type of user.
It is always possible to activate the heating mode, during the hot water supply: this function will not be activated until
the production of domestic hot water is completed.
It is possible to keep both CH and DHW functions activated but the boiler always gives priority to the use of DHW
mode with respect to CH.

In order to reduce gas consumption and to extend the water heater's life, Rinnai suggests to set
the device's temperature on the minimum which is more suitable for the intended use. Use hot
water on the pre-set temperature, so there is no need to mix it with cold water.
