What is standby mode in the Navien tankless water heater

Standby mode in Navien tankless water heaters refers to the state of the unit when it is not actively heating water, but is still powered on and ready to do so. When in standby mode, the unit is not using any gas or electricity to heat water, and is therefore not consuming any energy.

Navien tankless water heaters are designed to enter standby mode automatically when there is no demand for hot water. This helps to conserve energy and reduce operating costs by preventing the unit from continuously heating water unnecessarily. When a demand for hot water is detected, the unit quickly heats the water as it flows through the heat exchanger, providing a continuous supply of hot water on demand.

It is important to note that while in standby mode, the unit is still monitoring for any potential issues or errors. If an issue is detected, the unit will display an error code and may shut off completely to prevent any damage or safety hazards. Therefore, it is important to regularly maintain and service your Navien tankless water heater to ensure it is functioning properly and efficiently.

Sometimes after perfoming reset or after doing maintenance of tankless water heater the heater unit will be in standby mode for sometime and then it starts to operate.
