Local conditions suit efficient hot water beautifully. The nearby Hawthorn weather station records an average annual solar exposure of about 15 MJ/m² per day, which is roughly 4.2 kWh/m² per day of sunshine to help drive a solar hot water system or support a heat pump hot water system running on daytime solar power. With a median total household income of $2,654 a week and many homes owned outright or with a mortgage, investing in the most efficient hot water system is a logical next step for comfort, lower bills and future resale appeal. Moving from older gas systems or off‑peak cylinders to an energy efficient hot water system can trim a big chunk off your electricity use.
Across Malvern North 3144, we are seeing strong interest in both heat pump hot water installation and solar hot water installation. Households with existing rooftop solar often prefer a solar hot water system or a modern electric hot water installation controlled to run when the sun is shining, while others choose a compact heat pump for courtyards and side paths. Brands like Rheem heat pump hot water and Rheem solar hot water, Rinnai solar hot water and premium systems such as Sanden heat pump units are all popular options locally, along with Chromagen solar hot water for those wanting a reliable solar hot water tank replacement.
Typical hot water system price or cost will vary by size and brand, but the running cost difference is where Malvern North households really win. Depending on the scenario, you might see average annual bill savings such as:
• Old electric to heat pump hot water system: around $350–$700 per year. • Gas to heat pump hot water system: around $250–$600 per year. • Gas to solar hot water system: around $200–$500 per year. • Old electric to efficient electric hot water system with solar PV: around $250–$550 per year.
These are realistic ranges and can be even better for larger families or homes with big evening hot water demand. For many households comparing heat pump vs solar hot water, the choice comes down to roof space, budget and whether you already have solar panels. Both can rank among the best hot water system Australia options when properly sized and installed.
Recent data shows 167 efficient hot water systems have already been installed in the 3144 postcode, combining heat pump and solar hot water installations.

This long‑term trend reflects growing local interest in electrification, lower running costs and getting away from gas hot water. As more Malvern North homes add solar, pairing it with a heat pump hot water system or solar hot water heating system is becoming the obvious way to lock in lower bills.
Hot Water Rebates, Tariffs & Savings
Homeowners in Malvern North are increasingly replacing ageing gas or electric units with efficient options like a heat pump hot water system, updated electric hot water system or a solar hot water system to cut bills and future‑proof their properties. A key driver is the range of Australian Federal Government incentives and Victorian hot water rebate programs. Small‑scale Technology Certificates (STCs) act like an upfront discount on eligible systems, while state heat pump hot water rebate and solar hot water rebate schemes can further reduce the installed heat pump hot water price or cost and solar hot water price or cost. There are also electric hot water system rebate options when moving away from gas in some programs.
For Malvern North households, these hot water rebate VIC incentives can effectively trim system cost by a substantial percentage, meaning payback periods can drop from a decade to just a handful of years, especially if you run the system on solar. Many homes save hundreds of dollars per year after a hot water installation upgrade, particularly when using timers or solar diversion controls so the system heats when rooftop solar is producing. When you compare solar hot water vs electric hot water or electric hot water vs gas hot water, factoring in rebates and tariffs usually makes efficient electric or solar the clear winner over the life of the system.
