The Viomi intelligent hot water dispenser uses a patented cyclone heat system to control the flow of water through the system, avoiding energy wastage. It offers three preset common water temperatures, and unlimited personalized settings that can also be controlled through an app. If there is not enough water in the tank, the device first sends a reminder, then stops heating. The App can monitor the water quality at any time, reminding the user when to change it, and when to clean the pipe. A child lock protects against accidental burns in children.
