Dux hot water — common questions
Why is my Dux hot water system not working?
Dux systems can stop working due to a failed element or thermostat (Proflo electric), burner or thermocouple faults (Prodigy gas), ignition or flow sensor issues (Always Hot continuous flow), or compressor faults (Ecosmart heat pump). Our technicians carry common Dux parts and can usually diagnose and fix the fault in a single visit. Call us on 02 9344 6602 — we're available 24/7.
How long do Dux hot water systems last?
Dux tanks are Australian-made and built to last. Proflo electric and Prodigy gas storage systems typically last 10–15 years. Dux backs their tanks with up to a 7-year tank warranty. If your system is developing faults, we'll give you an honest assessment on whether repair or replacement makes more financial sense.
Can you repair a Dux Prodigy gas storage system?
Yes. Our gas-licensed technicians regularly repair Dux Prodigy gas storage systems — including burner faults, thermocouple and gas valve issues, anode replacement and pressure relief valve problems. The Prodigy is designed to operate without electricity, so it continues working even during a power outage.
Do you repair Dux Always Hot continuous flow systems?
Yes — we repair the full Always Hot range including non-condensing (17–32L/min) and condensing (21–26L/min) models. Common faults include ignition failure, temperature fluctuations, and flow sensor issues. Most are resolved in a single visit.
