Dux 21ENB5L Non-Condensing Continuous Flow 21 Litre 50 Degree Propane

Compact and efficient, the Dux 21ENB5L Continuous Flow units is an excellent option for Australian homes. Dux gas continuous flow water heaters heat the water only as needed, not wasting energy by keeping water in a tank hot, earning it a 6 star (or higher) energy rating. With several flow capacity models available, ensure you select a Dux continuous flow water heater that best suits to the number of outlets in the home.

Dux 21ENB5L continuous flow gas water heaters deliver hot water that will never run out as they heat water when you need it, for as long as you need it. Continuous flow water heaters work differently to storage water heaters, heating only on demand rather than heating and storing water until needed.

Your Dux 21ENB5L will be serving you for many years so make sure you choose the right capacity to meet your needs now and as your family grows
