Why is the water cold from my Dux Water Heater when only one fixture is open?
If the water is cold when only a single fixture is open with your Dux Water Heater, it's because the unit won't heat the water if the flow rate is less than 2.5 liters per minute. To resolve this, open the fixture more or open other fixtures to increase the flow through the unit, which should then start heating again.
