How Sanden Performs in Hawthorn East'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.

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
