How Dux Performs in Reservoir's Climate

Very GoodClimate Zone 6 | R290 refrigerant

Dux's R290 refrigerant is well-suited to climate zone 6. Propane (R290) holds its output in cooler conditions better than R134a does, making Dux a strong choice for this area. Winter mornings below 5 degrees will reduce efficiency slightly, but the system recovers quickly as temperatures rise.

Pros

  • The Ecosmart DHC range is designed and manufactured in Australia
  • On the Solar Victoria locally made list, so it earns the higher Victorian rebate tier
  • 7-year tank warranty
  • Y-class commercial enamel tank with dual anodes
  • Published COP of 4.63 on the 285L

Cons

  • Dux publishes no sound level for any Ecosmart model, so you cannot compare it on noise
  • Only 3 years on the heat pump components, and 1 year on everything else
  • The Pro-Series makes no Australian-made claim and is not on the locally made list
  • The model sold as 300DHC25 holds 285L, not 300L
  • No minimum operating temperature published for the DHC range

Victoria Gas Ban Affects Reservoir

From 1 March 2027, if the gas hot water system in an existing owner-occupied home breaks and cannot be repaired, it must be replaced with an electric alternative; in a rental it must be replaced with a heat pump water heater. Repairs are still allowed and exemptions exist. From 1 January 2027, new homes must be built all-electric.

With 81% of Reservoir homes connected to gas, switching to a Dux heat pump now locks in current rebate levels and avoids the rush as the deadline approaches.

A heat pump hot water system in Reservoir costs between $2,100 and $4,100 fully installed after all available rebates. Before rebates, expect to pay $3,700 to $5,700. The final price depends on the brand, tank size, and complexity of your installation.

These rebates are typically applied by your installer at the point of sale.
Are heat pumps efficient in Reservoir's climate?
Reservoir has a mild temperate climate with cool winters. Heat pumps work well in this climate zone but will see some efficiency reduction during cold winter mornings (below 5C). Split system models with CO2 refrigerant (Sanden, Reclaim) maintain better performance in cold conditions than integrated R134a models. A typical household of 3-4 people will spend $200-$400 per year running a heat pump, compared to $800-$1,200 for gas or $1,200-$1,800 for electric storage.
How does the Victoria gas ban affect Reservoir?
From 1 March 2027, if the gas hot water system in an existing owner-occupied home breaks and cannot be repaired, it must be replaced with an electric alternative; in a rental it must be replaced with a heat pump water heater. Repairs are still allowed and exemptions exist. From 1 January 2027, new homes must be built all-electric. With 81% of Reservoir homes connected to gas, this affects a significant number of households. The ban takes effect in approximately 5 months. Planning your switch to a heat pump now lets you choose the best system and installer on your timeline.
How long does a heat pump installation take in Reservoir?
A standard heat pump hot water installation in Reservoir takes 3-5 hours for a straightforward replacement. If you're converting from gas, it may take a full day as the installer needs to connect new electrical circuits and potentially modify plumbing. Metro installers typically have availability within 1-2 weeks.
What size heat pump do I need for my Reservoir home?
For Reservoir in climate zone 6: 1-2 people need a 150-170L tank, 3-4 people need a 250-315L tank, and 5+ people should consider a 315-400L tank. In cooler climates like yours, sizing up one tank size is recommended to ensure adequate hot water on cold mornings.
Which heat pump brand is best for Reservoir?
In Reservoir's cooler climate (zone 6), CO2 refrigerant models perform best. Sanden and Reclaim Energy maintain efficiency down to -10C, while R134a models like iStore and Rheem lose efficiency below 5C. If noise is a concern (common in metro areas with close neighbours), split system models (Sanden at 38dB, Reclaim at 37dB, Daikin at 40dB) are significantly quieter than integrated units.
