Hot water systems in Mullaloo
Across Mullaloo and the 6027 postcode, more locals are swapping old gas and electric units for an energy efficient hot water system that actually suits how they live. With an average household size of around 2.6 people and more than 15,000 dwellings, there is strong demand for reliable hot water that does not send bills through the roof. Many homes are owned with a mortgage or outright, so upgrading a tired hot water system is a logical step to add value and comfort while trimming running costs.
Mullaloo’s coastal sunshine is a big part of the story. The Beeneyup weather station records about 19.3 MJ/m² of solar exposure a day – roughly 5.4 kWh/m² – which is excellent for both a solar hot water system and a heat pump hot water system. That level of sun means a solar hot water heating system on the roof, or a Sanden heat pump or Rheem heat pump hot water unit in the yard, can do most of the hard work using free renewable energy. When you upgrade from older gas or resistive electric hot water to a modern electric hot water system, heat pump or solar hot water system, annual hot water energy savings can easily reach hundreds of dollars for a typical Mullaloo family.
In 6027 there is a big mix of three and four bedroom homes, so hot water demand is steady, especially for families and multi‑generational households. At the same time, energy prices keep creeping up, so hot water energy use is a growing slice of the total bill. That is why interest in the best hot water system Australia can offer – particularly the best heat pump hot water system options – is rising fast, alongside brands like Rheem, Rinnai and Chromagen solar hot water on local roofs.
Typical annual bill savings for Mullaloo homes look like this:
• Old electric to heat pump hot water installation: save about $350–$700 per year. • Gas to heat pump vs solar hot water: either option can save roughly $250–$600 per year, depending on usage. • Gas to solar hot water installation with PV: often $300–$650 per year. • Old electric to modern electric hot water installation using rooftop solar: around $200–$450 per year.
These ranges depend on tariffs, household size and how well the system is set up with timers or solar diversion, but they show why people are comparing solar hot water vs electric hot water and electric hot water vs gas hot water more seriously.
Mullaloo and the broader 6027 area already have 3,061 efficient hot water systems installed, combining heat pump hot water installation and solar hot water installation over the years. Installations climbed steadily through the 2000s, peaking around 2010 with over 400 systems in a year as early rebates kicked in, and have remained solid since, with 70–110 installs most years from 2018 onwards. That trend reflects a clear local shift towards electrification, lower running costs and using that strong WA sunshine more effectively. As systems age, there is also a steady trickle of solar hot water repair, electric hot water repair and solar hot water tank replacement work keeping everything running smoothly.
Hot Water Rebates, Tariffs & Savings
Across Mullaloo, more households are now planning ahead, replacing old gas storage units or ageing electric cylinders with efficient options before they fail. Federal incentives like Small‑scale Technology Certificates (STCs) help cut the solar hot water price / cost and heat pump hot water price / cost by effectively acting as an upfront discount. On top of that, WA homeowners can often access a solar hot water rebate or heat pump hot water rebate through various programs, and in some cases an electric hot water system rebate when moving away from gas. For many Mullaloo homes, these hot water rebate wa incentives can trim the hot water system price / cost by a substantial percentage, bringing quality systems like Rheem solar hot water, Rinnai solar hot water or a premium Sanden heat pump within reach. Once installed, an energy efficient hot water system can shave hundreds of dollars a year off bills, and when paired with rooftop solar and smart timers, the payback period can be cut dramatically compared with running an old gas or electric unit.
