Critical Review: Saxon Electric Storage Hot Water Systems – What’s the Best Replacement?

For many Queenslanders, Saxon wasn’t just a brand—it was a household name. With a legacy spanning over 100 years, Saxon and Peter Sachs Industries dominated the Queensland hot water market before shutting down in 2011. Today, the Saxon name is owned by Rheem, but Saxon systems are no longer produced, leaving thousands of homeowners wondering: What’s the best replacement?

At JR Gas & Water, we’ve helped countless Saxon owners transition to modern, energy-efficient systems. Whether you had a Saxon Copperflow, Trueflow, Superflow Heat Pump, or SolarStar, there are excellent alternatives to suit your budget, household size, and energy goals.

Why Did Saxon Hot Water Systems Disappear?

Despite their simple and durable design, Saxon hot water systems fell behind modern energy regulations. Their open-vented design lost significant heat through the top expansion outlet, forcing the element to run frequently and driving up power bills.

Other drawbacks included:

• Manual top-up valves requiring regular refilling

• Inconsistent water temperature if the system was not maintained

• High long-term running costs compared to sealed systems and heat pumps

While Saxon units were affordable to install, they’re now outdated compared to today’s high-efficiency options.

Best Replacements for Saxon Hot Water Systems

Choosing the right replacement depends on:

• ✅ System location – Indoor, outdoor, or space constraints?

• ✅ Household size – Number of people needing hot water?

• ✅ Budget – Most affordable or premium?

• ✅ Energy efficiency goals – Looking to reduce power bills?
