AquaMax Hot Water Systems

Aquamax 250l electric hot water system.

AquaMax, an Australian-owned and operated company, was the first to release an electric hot water system with a 5-star energy rating and 10-year warranty. This Aquamax hot water system is the first of its kind in Australia to offer such high levels of energy efficiency as well as long-term warranties.

Furthermore, AquaMax hot water systems are renowned for their use of stainless steel tanks. This sets AquaMax apart from other brands of hot water systems since not all storage systems are made with stainless steel.

AquaMax’s stainless steel tanks are exceptionally lightweight and can withstand high temperatures. The stainless steel construction also means that AquaMax hot water systems are highly resistant to corrosion, ensuring a long lasting product with excellent performance.


Another impressive fact about AquaMax hot water systems that has caught the attention of many savvy homeowners is their lack of anode. An anode is a component of a water heater which can potentially corrode in time, leading to more frequent maintenance and repairs.

AquaMax systems don’t use anodes, so they provide purer hot water without the worry of corrosion or rusting. The absence of anodes also means less sediment buildup over time, making it easier to maintain your system and keep it working properly for years to come.

Here are the two main offerings of the AquaMax range:


  • Gas Storage/Mains Pressure Gas Storage: This line of AquaMax 5-star gas heaters are the latest innovation in heating technology, offering mains pressure and a sleek stainless steel cylinder design. The AquaMax G390SS, G340SS, and G270SS models come with 12-year cylinder warranties, ensuring long-term reliability for both residential and commercial applications. Designed to keep up with high hot water demands. 

  • Electric Storage/Vitreous Enamel: Made from steel and lined with vitreous enamel, this product range offers the highest level of protection against rust and corrosion. With sizes ranging from 50L to 400L, AquaMax electric storage ensures that you will always have plenty of hot water available when you need it most. 


At Mr Plumber, we offer specialised advice to help you find the perfect product for your home or business. Whether it’s the heavy duty AquaMax G390SS or the lighter AquaMax 50L electric storage you need, our team can provide you with the best solutions to suit your unique requirements. 

We can find the best deals and exclusive discounts on select models, so that you get value for money when purchasing your AquaMax products. Get in touch with us today on 1800 758 623 and we’ll be more than happy to answer any queries or questions that you may have.
