How Rinnai Performs in Fairfield's Climate

GoodClimate Zone 6 | R134a refrigerant

Rinnai will perform adequately in climate zone 6, though cooler winter temperatures (below 5 degrees) will reduce efficiency more noticeably than CO2 refrigerant alternatives like Sanden or Reclaim. Consider sizing up to a larger tank capacity to build stored heat during warmer parts of the day and reduce reliance on the heat pump during cold mornings.

Noise Levels in a Metro Area

At 46dB, Rinnai produces moderate noise comparable to a quiet conversation. In metro areas with close neighbours, consider placement on the side of the home furthest from neighbouring bedrooms.

Pros

  • Australia's most trusted hot water brand
  • AR Series is Australian-made (higher VIC rebate)
  • Widest installer network in AU
  • 340L is largest integrated residential heat pump in AU
  • Smooth transition path from Rinnai gas

Cons

  • Not the most efficient COP vs CO2 brands
  • Only AR Series is Australian-made
  • E-Series has shorter warranty
  • Standard R134a refrigerant

How does the Victoria gas ban affect Fairfield?

How long does a heat pump installation take in Fairfield?
A standard heat pump hot water installation in Fairfield 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 Fairfield home?
For Fairfield 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 Fairfield?
In Fairfield'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.
