With an average household size of around 2.6 people and more than 1,800 families in the area, reliable hot water for showers, laundry and guests is essential. At the same time, rising energy costs mean upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step.
South Molle enjoys excellent sunshine, with mean daily solar exposure of about 19.4 MJ/m² – roughly 5.4 kWh per square metre per day. That strong sun is ideal for a solar hot water heating system or a high‑performance heat pump hot water system that sips electricity while drawing warmth from the air. With many homes owned outright or with a mortgage, and a median household income around $1,768 per week, locals are well placed to invest in upgrades that lock in long‑term savings and cut emissions from older gas hot water.
Across the 4741 postcode, there are 2,324 occupied private dwellings, most of them three and four‑bedroom separate houses. That means solid hot water demand, especially for families and holiday accommodation. A significant share of homes still rely on older gas or resistive electric hot water, even though hot water energy use can be one of the biggest chunks of a power bill. Efficient options like Rheem heat pump hot water, Sanden heat pump models, and solar brands such as Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are increasingly seen as some of the best hot water system Australia has to offer for coastal climates.
Typical annual bill savings for South Molle households can look like this:
• Old electric to heat pump hot water system: save around $400–$800 per year. • Gas hot water to heat pump: save roughly $300–$600 per year. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation with rooftop solar: save around $300–$700 per year.
Recent data shows 241 efficient hot water installations (heat pump and solar hot water installation combined) recorded in the 4741 area. Installations built steadily through the 2000s, peaking around 2009 with 34 systems, and remaining consistent in later years. While numbers dipped during 2020–2024, the long‑term trend reflects growing local interest in electrification, lower running costs and choosing the most efficient hot water system for coastal homes and businesses.
When it comes to hot water installation and hot water repair in QLD, rebates and tariffs make a real difference. Federal Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost or heat pump hot water price / cost, and Queensland hot water rebate programs can apply to approved heat pump hot water installation or solar hot water installation. There are also schemes that support an electric hot water system rebate when replacing old gas hot water. In practice, these discounts can cut the system cost by 20–40%, turning a multi‑year payback into just a few years, especially if you already have rooftop solar or use timers and solar diversion to run your electric hot water installation when the sun is shining.
Choosing between heat pump vs solar hot water, or weighing solar hot water vs electric hot water, comes down to your roof space, budget, and how you use energy. A quality Sanden heat pump or other best heat pump hot water system can be ideal for shaded roofs or apartments, while a roof‑mounted solar hot water tank replacement from brands like Rheem or Rinnai can be perfect for sun‑drenched family homes. For some properties, a simple, modern electric hot water system paired with solar PV gives a reliable, energy efficient hot water system that outperforms old electric hot water vs gas hot water on running costs.
