How Quantum Performs in Amaroo's Climate

GoodClimate Zone 7 | R290 refrigerant

Climate zone 7's cold winters will reduce heat pump efficiency, but Quantum's R290 system handles cold conditions better than R134a does. Expect running costs 10-15% higher than manufacturer estimates during winter months. A larger tank (315L+) is recommended to maximise heat storage during warmer daytime hours.

Noise Levels in a Metro Area

At 50dB, Quantum is on the noisier end of heat pumps. In a metro area, careful placement is essential to avoid neighbour disputes. Check your local council's noise regulations and avoid installing near bedroom windows or boundary fences.

Pros

  • Four tank sizes from 150L to 340L, the widest range here
  • A 150L option, which almost no other brand offers
  • Australian company with a manufacturing facility at Seaford, South Australia
  • Propane (R290) across the range
  • On the register since 2014, so the models have a long track record

Cons

  • Not on the Solar Victoria product list at all, so a Quantum does not qualify for the Victorian hot water rebate
  • Only 2 years on the electrical and refrigeration parts, the shortest here
  • Quantum publishes no labour warranty term
  • The product pages and the 270L data sheet disagree on the minimum operating temperature (-10C against -15C)
  • 50 dB on the 150L and 200L

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 Amaroo?

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 Amaroo home?
For Amaroo in climate zone 7: 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.
