Are heat pumps efficient in Langwarrin's climate?

How does the Victoria gas ban affect Langwarrin?
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 80% of Langwarrin 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 Langwarrin?
A standard heat pump hot water installation in Langwarrin 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 Langwarrin home?
For Langwarrin 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 Langwarrin?
In Langwarrin's cooler climate (zone 6), CO2 refrigerant models perform best.

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.
