How it works


A hot water tap is opened.
The water enters the heater.
A water flow sensor detects the water flow.
The computer automatically ignites the burner.
The water circulates through the heat exchanger (coil).
The heat exchanger instantly heats the water at the designated temperature (this takes only 5 seconds).
The heater can provide you with endless hot water continuously so no more running out of hot water in the middle of a shower!
When the hot water tap is turned off, the unit shuts down automatically.
