That solar resource, combined with rising electricity prices, makes upgrading from older gas or electric hot water to a more efficient hot water system a logical next step. Many homeowners in 4184 can trim a big chunk off their annual hot water energy use, because hot water can account for up to a quarter of a typical home’s power bill.
Around 4,114 occupied private dwellings in the postcode, mostly separate houses, means strong demand for dependable hot showers, especially for the 3,300+ residents over 65.

In 4184, a total of 516 efficient hot water systems have already been installed, combining heat pump and solar hot water installation projects. Installations rose sharply around 2009–2011, when annual numbers peaked at over 40–50 systems per year, and there has been steady activity right through to 2024 and 2025. This long‑term trend shows growing local interest in heat pump vs solar hot water options, electrification, and lower running costs, especially as more homes add rooftop solar and look for the most efficient hot water system to pair with it.
For many island homes, a heat pump hot water system is a great match with rooftop solar, using off‑peak or daytime excess to heat water. Brands like Sanden heat pump and Rheem heat pump hot water are popular where quiet operation and high efficiency matter. If you prefer roof‑mounted collectors, a Rheem solar hot water or Chromagen solar hot water setup can deliver strong performance in our sunny QLD climate. Rinnai solar hot water systems are also common for compact homes wanting a reliable solar hot water tank replacement.
Typical hot water system price or cost will depend on the size of your household and whether you choose a premium brand. As a rough guide, a quality heat pump hot water price or cost is higher upfront than a basic electric hot water installation, but running costs are far lower. A solar hot water price or cost usually sits between the two, especially once you factor in the solar hot water rebate and federal incentives. When you weigh solar hot water vs electric hot water, or electric hot water vs gas hot water, most Perulpa Island households find the long‑term savings and comfort of going efficient are well worth it.
Here are some realistic average annual bill savings many 4184 homes can achieve:
• Replacing an old electric hot water system with a heat pump hot water system: $400–$800 per year • Switching from gas to a heat pump hot water system: $300–$600 per year • Switching from gas to a solar hot water system: $250–$550 per year • Upgrading an old electric unit to a modern electric hot water system and using rooftop solar: $200–$500 per year
Hot water repair and replacement are common triggers for upgrading. If your existing system is more than 10–12 years old, noisy, rusty, or running out of hot water, it may be smarter to invest in a new energy efficient hot water system rather than another hot water repair. Local installers can guide you on the best hot water system Australia offers for your situation, whether that is a compact electric hot water system rebate‑eligible unit or a premium best heat pump hot water system matched to your tariff and solar.
