Why Choose Hot Water Maintenance For Dux Systems

Dux is one of the most established hot water brands in Australia — their Proflo electric storage range in particular has been a staple in Sydney and Wollongong homes for decades. That long market presence means our technicians have extensive experience across Dux’s full product history, from older Proflo electric tanks through to the current Ecosmart heat pump range.
Because Dux electric storage systems are so widely installed, common fault types — failed elements, thermostat issues, valve problems, anode rod deterioration — are well understood and parts are readily available. Many standard Dux repairs are completed on the same visit.
For Dux Ecosmart heat pump systems, our technicians are experienced with the specific fault patterns of Australian-made heat pump technology, including the Ecosmart’s patented dual wall heating coil design and Wi-Fi controller diagnostics. Whether the job is a Proflo element repair or an Ecosmart heat pump service, we give you an honest assessment before any work begins.
Common Dux Faults We Repair

We diagnose before we quote
Every fault traced to its actual cause — no guesswork.
Failed heating elements in Dux Proflo electric storage systems — the most common fault across the Proflo range
Thermostat failure — water that is too hot, too cold or inconsistent
Pressure relief valve and tempering valve issues across Dux storage systems
Anode rod deterioration — sacrificial anodes deplete over time and require replacement to protect the tank from corrosion
Tank leaks from the cylinder, valves or pipe connections — common in older Proflo systems near end of life
Compressor and sensor faults on Dux Ecosmart heat pump systems
Wi-Fi controller and touchscreen issues on Dux Ecosmart DHC and Pro-Series units
Refrigerant and airflow problems reducing Ecosmart heat pump performance
Pilot light and burner faults on Dux gas storage systems
Corrosion on external components — particularly relevant for coastal properties across Sydney and Wollongong
If your Dux system has stopped heating, is leaking, tripping the power, showing error codes or simply not keeping up with household demand, our technicians can assess the fault and advise on the most practical repair or replacement option.
