I have read of hot water cylinders being heated with a dual element immersion heater. The main principle being that a shorter element heats the top of the tank and then, subsequently, a longer element comes into play. With a bath/sink switch the longer element may be disabled. The topic of such dual heaters has appeared occasionally in this forum.
However, I have been unable to find any supplier for such an immersion heater. Please, does anyone know if these are still available?
Any advice/links would be appreciated.
