How Rheem Performs in Hamilton's Climate

GoodClimate Zone 6 | R134a refrigerant

Rheem 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 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
  • R134a refrigerant (less eco-friendly than CO2)

Victoria Gas Ban Affects Hamilton

New builds already banned from gas connections since January 2024. Rentals also face mandatory replacement of gas heaters.

With 52% of Hamilton homes connected to gas, switching to a Rheem heat pump now locks in current rebate levels and avoids the rush as the deadline approaches.

Are heat pumps efficient in Hamilton's climate?
Hamilton 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 Hamilton?
From 1 March 2027, gas hot water systems in existing homes must be replaced with an efficient electric alternative (heat pump) when they reach end-of-life. Repairs are still allowed. New builds already banned from gas connections since January 2024. Rentals also face mandatory replacement of gas heaters. With 52% of Hamilton homes connected to gas, this affects a significant number of households. The ban takes effect in approximately 10 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 Hamilton?
A standard heat pump hot water installation in Hamilton 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 Hamilton home?
For Hamilton 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 Hamilton?
In Hamilton'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.
