AquaMAX 390

The AquaMAX 390 patented inbuilt mixing valve gives you 390 litres first hour delivery with a five star energy rating.

While the tank holds 155 litres, the stainless steel cylinder can store water at a much higher temperature than a vitreous enamel tank. The mixing valve (Control A) adds a controlled mix of cold water at the unit’s hot water outlet, giving 205 litres or more hot water delivery in the initial draw, at 60ºC or at the setting you choose when Control B is set at 4.5 or higher.

With 185 litres recovery per hour after that, the 390 is the largest volume domestic storage water heater available.

As an installation option, your plumber can install twin temperature delivery. This will give you greater flexibility so you can enjoy the convenience of 65ºC hot water in the kitchen and laundry when you need it, while taking comfort in the knowledge that it is safer for kids with bathroom hot water taps at 50ºC or lower.
