How Quantum Performs in Stirling's Climate

ExcellentClimate Zone 5 | R290 refrigerant

Quantum's R290 system handles climate zone 5's moderate conditions with ease. You'll see near-optimal COP performance throughout the year, with only minor dips during the coolest winter mornings.

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
