Dux 400L 3.6kw Proflo, Great product which I highly recommend
Since this was installed we have hotter water than before which costs us less . No issues at all. Has been in for 4 weeks now. Copes easily with four adults showering in the mornings. Easier with the Bunnings service, they arrange the installer, we called 4 plumbers with no luck before we went to the store to arrange the installation and choice of unit. They helped with choosing the unit.
