Hot water systems in Millbank
Across Millbank and the wider 2440 area, more households are switching from old gas and ageing electric units to an energy efficient hot water system. With an average household size of around 2.4 people and more than 8,000 occupied dwellings, reliable hot water is non‑negotiable – but so is keeping running costs under control. Many homes are owned outright or with a mortgage, so upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical step to protect budgets and future‑proof properties.
Millbank enjoys strong sunshine, with mean daily solar exposure of about 17.1 MJ/m² – roughly 4.75 kWh/m² per day. That level of sun makes both a solar hot water heating system and heat pump hot water a smart fit, especially for families and older residents who are home during the day and can maximise solar use. When you pair the local climate with rising energy prices and modest median household incomes, shifting from gas hot water to an energy efficient hot water system can deliver meaningful annual hot water energy savings for Millbank homeowners.
In the 2440 postcode, most dwellings are separate houses, many with three or four bedrooms, so hot water demand is steady year‑round. Efficient hot water systems – including heat pumps and solar – are increasingly common on new builds and renovations, especially where rooftop solar is already installed. Local installers regularly work with brands such as Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and premium Sanden heat pump units, helping households choose what suits their budget and roof space while aiming for the most efficient hot water system for their needs.
Typical annual bill savings in Millbank look like this:
• Replacing an old electric hot water system with a heat pump hot water system: save roughly $350–$700 per year. • Switching from gas hot water to a heat pump: save around $300–$600 per year. • Switching from gas to a solar hot water system: save about $250–$550 per year. • Upgrading an old electric hot water system to a modern electric hot water system and using solar: save around $200–$450 per year.
To date, there have been 2,238 efficient hot water installations (heat pump hot water installation and solar hot water installation combined) recorded in the 2440 postcode. Installations ramped up sharply around 2008–2010, when yearly numbers peaked at 269–360 systems, driven by early solar hot water rebate support. While volumes eased in later years, there has been renewed interest around 2020 and again in 2025, reflecting a fresh focus on electrification, lower running costs and replacing ageing systems with the best heat pump hot water system or best hot water system Australia options available locally.
