How Rheem Performs in Morwell's Climate

GoodClimate Zone 6 | R513a refrigerant

Rheem 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 Regional Area

At 48dB, Rheem produces moderate noise. In a regional area, the extra distance between properties means noise is less of a concern than in metro locations.

Pros

  • Well-known trusted brand
  • Wide installer network
  • Integrated design (simpler install)
  • Competitive pricing
  • Australian made and owned

Cons

  • Shorter warranty than premium brands
  • Lower COP than Sanden/Reclaim
  • Noisier than split systems
  • R513a refrigerant, not the CO2 used by the premium split systems

Victoria Gas Ban Affects Morwell

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 Morwell's climate?
Morwell 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 Morwell?
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 58% of Morwell 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 Morwell?
A standard heat pump hot water installation in Morwell 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. Regional installations may require scheduling 2-4 weeks ahead.
What size heat pump do I need for my Morwell home?
For Morwell 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 Morwell?
In Morwell'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 quiet regional settings), split system models (Sanden at 38dB, Reclaim at 37dB, Daikin at 40dB) are significantly quieter than integrated units.
