How Quantum Performs in Howard Springs's Climate

ExcellentClimate Zone 1 | R290 refrigerant

Quantum performs exceptionally well in climate zone 1. With warm ambient temperatures for most of the year, the R290 refrigerant system will operate near its rated COP of 4.3. Running costs will be at the lower end of estimates, and you can expect consistent hot water delivery year-round.

Noise Levels in a Regional Area

At 50dB, Quantum produces moderate noise. In a regional area, the extra distance between properties means noise is less of a concern than in metro locations.

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

How long does a heat pump installation take in Howard Springs?
