Mount Martha 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.

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 72% of Mount Martha 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.

A standard heat pump hot water installation in Mount Martha 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.

For Mount Martha 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.

In Mount Martha'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.
