    How it works

    1. A hot water tap is turned on

    2. Water enters the heater

    3. The water flow sensor detects the water flow

    4. The computer automatically ignites the burner

    5. Water circulates through the heat exchanger

    6. The warmed water passes through a second heat exchanger to the designated temperature

    7. When the tap is turned off, the unit shuts down
