How Sanden Performs in South Melbourne's Climate

Very GoodClimate Zone 6 | CO2 refrigerant

Sanden's CO2 refrigerant is well-suited to climate zone 6. CO2 holds its output in cooler conditions better than R134a does, making Sanden a strong choice for this area. Winter mornings below 5 degrees will reduce efficiency slightly, but the system recovers quickly as temperatures rise.

Noise Levels in a Metro Area

At 38dB, Sanden is one of the quietest heat pumps available, which is important in metro areas where units are often installed close to neighbouring properties. You're unlikely to receive noise complaints at this level.

Pros

  • Industry-leading COP of 5.1
  • 15-year tank warranty (best in class)
  • CO2 refrigerant
  • Extremely quiet
  • Proven Japanese engineering
  • Best long-term value

Cons

  • Highest upfront cost
  • Split system requires indoor tank space
  • Longer lead times from Japan

Victoria Gas Ban Affects South Melbourne

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 79% of South Melbourne homes connected to gas, switching to a Sanden heat pump now locks in current rebate levels and avoids the rush as the deadline approaches.

Are heat pumps efficient in South Melbourne's climate?
South Melbourne 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 South Melbourne?
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 79% of South Melbourne 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 South Melbourne?
A standard heat pump hot water installation in South Melbourne 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 South Melbourne home?
For South Melbourne 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 South Melbourne?
In South Melbourne'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.
