The smart temperature control valve (mixing valve) is
applied to all Navien water heater models.

The mixing valve is a high-tech valve that makes hot water a certain temperature by
instantaneously measuring the temperature of water from the water heater and mixing in cold water when the
temperature is too high to maintain a constant water temperature.

Hot water at a certain temperature without fluctuation

As more sophisticated TDR (flame size adjustment) automatically controls the flame by 100 – 14% depending on required heat,the product not only secures more precise hot water performance, but also saves gas charges by preventing any unnecessary gas consumption.

Application of APS (air pressure sensor),real-time smart air detection technology, for the first time in Korea

KD Navien gas water heater ensures your safety.
