Hot water systems in Greenmount
Across Greenmount and the wider 6056 area, more households are switching from old gas and ageing electric units to an energy efficient hot water system that keeps bills down and showers hot. With an average household size of around 2.4 people and more than 16,000 dwellings in the postcode, reliable hot water is essential, but rising energy prices mean many locals are rethinking how they heat their water. The good news is that Greenmount’s strong sunshine – about 19 MJ/m² of solar exposure a day, or roughly 5.3 kWh/m² – makes both a solar hot water system and a heat pump hot water system a smart upgrade from a traditional electric hot water system.
With a big share of homes either owned outright or with a mortgage, and median household incomes that support long term investments, upgrading from older gas hot water to a modern energy efficient hot water system is a logical next step. Annual hot water energy savings in Greenmount can be significant when you move to a heat pump hot water installation or solar hot water installation, especially if you already have rooftop solar. For many families and downsizers in the area, hot water now accounts for a large slice of household energy use, so choosing the most efficient hot water system can make a real dent in quarterly bills.
In the 6056 postcode, thousands of separate houses and townhouses mean plenty of roof space and yards suited to a solar hot water heating system or an outdoor heat pump. A typical Greenmount family using a 250–315 litre hot water system can cut running costs sharply by upgrading. To give you a feel for the savings, here are realistic average annual bill reductions:
• Old electric hot water to heat pump hot water system: $450–$900 per year • Gas hot water to heat pump hot water: $350–$750 per year • Gas hot water to roof-mounted solar hot water system: $300–$700 per year • Old electric to modern electric hot water system with rooftop solar: $250–$600 per year
Local installers commonly work with trusted brands like Rheem, Rinnai, Sanden and Thermann.

This trend reflects growing local interest in electrification, lower running costs and moving away from gas hot water towards heat pump hot water installation and solar hot water installation backed by rooftop solar.
Hot Water Rebates, Tariffs & Savings
Around Greenmount WA, more people are comparing heat pump vs solar hot water and even looking at modern electric hot water vs gas hot water as they plan an all electric home. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that reduces the purchase price. On top of that, WA programs and occasional retailer offers can stack with STCs to bring the heat pump hot water price or cost, or the solar hot water price or cost, down by a substantial percentage. For some households, that means a payback period of only five to seven years, especially when you combine a solar hot water heating system or efficient electric hot water installation with rooftop solar and smart timers that run the system during the middle of the day. Typical savings of hundreds of dollars per year are common, and when you factor in an electric hot water system rebate and lower maintenance through timely hot water repair and solar hot water repair, the long term value improves even further. If your existing solar hot water tank replacement is overdue, using rebates at the same time can make a big difference to the overall hot water system price or cost.
If you live in Greenmount WA and your current unit is older, noisy or struggling, this is a good time to check whether a heat pump, solar hot water vs electric hot water, or efficient modern electric hot water system is right for your home. Working with experienced local hot water installers who specialise in hot water installation, hot water repair, solar hot water tank replacement and full electric hot water installation means you get the right advice on brands, tariffs and hot water rebate WA options.
