How Rinnai Performs in Donvale'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 a CO2 or propane unit would. 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.

  • AR Series is Australian-made (higher VIC rebate)

  • 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

Victoria Gas Ban Affects Donvale

From 1 March 2027, if the gas hot water system in an existing owner-occupied home breaks and cannot be repaired, it must be replaced with an electric alternative; in a rental it must be replaced with a heat pump water heater. Repairs are still allowed and exemptions exist. From 1 January 2027, new homes must be built all-electric.

Are heat pumps efficient in Donvale's climate?
Donvale has a mild temperate climate with cool winters. Heat pumps work well in this climate zone but will see some efficiency reduction during cold winter mornings (below 5C). Split system models with CO2 refrigerant (Sanden, Reclaim) maintain better performance in cold conditions than integrated R134a models. A typical household of 3-4 people will spend $200-$400 per year running a heat pump, compared to $800-$1,200 for gas or $1,200-$1,800 for electric storage.
How does the Victoria gas ban affect Donvale?
From 1 March 2027, if the gas hot water system in an existing owner-occupied home breaks and cannot be repaired, it must be replaced with an electric alternative; in a rental it must be replaced with a heat pump water heater. Repairs are still allowed and exemptions exist. From 1 January 2027, new homes must be built all-electric. With 85% of Donvale homes connected to gas, this affects a significant number of households. The ban takes effect in approximately 5 months. 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 Donvale?
A standard heat pump hot water installation in Donvale 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 Donvale home?
For Donvale 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 Donvale?
In Donvale'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.
