Dux hot water heat pump FAQ
How much is a Dux hot water heat pump installed in 2026?
A Dux hot water heat pump costs $3,300 - $3,850 fully installed in Australia before rebates. The cheapest model (Dux Ecosmart 200DHC25 (200L), 200L) starts at $3,300; the largest (Dux Ecosmart 300DHC25 (285L), 285L) tops out around $3,850. After stacking federal STCs (worth $600-$600 depending on the model and your climate zone) and state-based rebates, most households pay $1,300-$2,750 out of pocket.
Is Dux a good heat pump brand?
Dux has made hot water systems at Moss Vale in New South Wales for decades and is now part of the Noritz group. The Ecosmart DHC range is designed and manufactured in Australia and is on Solar Victoria's locally made list, which is what puts it in the higher Victorian rebate tier. Tanks are Y-class commercial enamel with dual anodes, and the 285L publishes a coefficient of performance of 4.63. The Pro-Series is a separate 270L model with a larger 3.6 kW heat pump. Dux is best suited to victorian households chasing the higher locally made rebate tier, and anyone who wants an australian-built tank.
What rebates can I claim on a Dux heat pump?
Every Dux model attracts federal Small-scale Technology Certificates (STCs) worth $600-$600 at point of sale. On top of STCs, Victorian households can stack the Solar Victoria Hot Water Rebate ($1,000-$1,400) and Victorian Energy Upgrades discount ($500-$2,000) to reach up to $2,700 in rebates. NSW (Energy Savings Scheme), SA (REPS), and ACT (Sustainable Household Scheme) have their own state-level top-ups. Most of it is automatic: STCs, Victorian Energy Upgrades and the NSW Energy Savings Scheme are already inside the price your installer quotes. Solar Victoria's rebate is the one worth going after on top, and your installer drives it. They lodge it with your quote, you add ID and proof of income, and it comes off your invoice on approval.
What is the warranty on a Dux heat pump?
Dux backs its tanks with a 7-year warranty and the compressor with 3 years. Workmanship cover for the install itself comes from your installer separately and should be at least 12 months. Warranty claims require the system to have been installed by a licensed plumber and serviced according to the manual.
How efficient is a Dux heat pump?
The Dux Ecosmart 200DHC25 (200L) runs at COP 4.23 (every 1 kWh of electricity input produces 4.23 kWh of heat output). Annual running cost is around $280 for a 2-3 person household, compared to roughly $700/year for gas storage and $900/year for old-school electric resistive storage.
How long does a Dux heat pump last?
Modern hot water heat pumps last 12-15 years on average in Australian conditions. Tank life depends on water hardness (sacrificial anode replacement every 5 years extends life). Compressor life is the limiting factor and typically matches or exceeds the warranty period when the unit is correctly sized and serviced.
Dux vs other brands: which should I pick?
Dux sits at the budget end of the Australian market. It strikes a balance between quality and price. See the side-by-side comparisons below for direct head-to-head specs.
How noisy is a Dux Ecosmart heat pump?
Dux does not publish a sound level for the Ecosmart range, in its spec sheets, on its product pages or in its manuals. That is unusual: most makers publish a figure measured one metre from the unit. If noise matters, ask the installer for a written figure before you commit, or choose a brand that publishes one. We will not print a number here that the maker does not stand behind.
Which Dux models qualify for the higher Victorian rebate?
The Ecosmart 200DHC25 and 300DHC25 families are on Solar Victoria's locally made product list, which carries the higher hot water rebate tier. The Pro-Series is not on that list. If you are claiming the Victorian rebate, check the exact model number on your quote against the current Solar Victoria list, because products move on and off it.
