Hot Water Only When You Need It
A continuous flow unit has no storage tank. It sits idle until a tap opens, then a flow sensor fires the burner and heats the water as it passes through the heat exchanger. When the tap closes the burner shuts down, so there is no standing heat loss from keeping a tank hot around the clock.
