With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Rewan and the 4702 area, 2,215 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Rewan's climate delivering an average of 5.7 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Rewan
Across Rewan and the wider 4702 area, more households are switching from old gas and ageing electric units to an energy efficient hot water system. With most locals living in separate houses and an average household size of around 2.7 people, daily hot water demand is solid – and so are the savings when you upgrade. Median household incomes here are steady, so it makes sense to cut running costs rather than just wear rising power prices.
Rewan is blessed with sunshine. The local weather station records an average annual solar exposure of about 20.3 MJ/m² a day – roughly 5.6 kWh/m² – which is ideal for a solar hot water system or high performance heat pump hot water system. That strong solar resource means a modern solar hot water heating system or quality heat pump can comfortably cover most of a family’s hot water needs, especially if you already have rooftop solar. For many homes, hot water is one of the biggest single energy loads, so the annual hot water energy savings from upgrading can be substantial.
Around 4702 there are close to 10,000 occupied dwellings, many owned outright or with a mortgage, which is why we are seeing more interest in long term solutions like Rheem solar hot water, Rinnai solar hot water and premium options such as Sanden heat pump systems. Brands like Rheem heat pump hot water and Chromagen solar hot water are popular for those chasing the most efficient hot water system they can get, while still keeping the overall hot water system price / cost under control.
Typical hot water installation choices in Rewan include a straight swap to a modern electric hot water system, a highly efficient heat pump hot water installation, or a full solar hot water installation with a roof mounted or ground mounted solar hot water tank replacement. Many locals also ask about heat pump vs solar hot water, or solar hot water vs electric hot water, to work out what suits their roof, budget and lifestyle. For some, the best hot water system Australia can offer is a top tier heat pump paired with solar; for others, a reliable electric hot water installation on a smart tariff does the job.
In the 4702 postcode there have already been 2,215 efficient hot water systems installed, including both heat pumps and solar hot water. Installations peaked during the big solar years of 2007–2010, when annual numbers jumped above 200 systems, and while volumes have eased back to dozens of installs a year, recent data still show steady interest through 2022–2024. This long running trend reflects how more Rewan households are looking to electrify, move away from gas hot water, and lock in lower running costs with an energy efficient hot water system.
For a typical Rewan home, upgrading can deliver strong bill savings:
• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas to heat pump hot water: save around $250–$600 per year. • Gas to solar hot water system: save about $300–$650 per year. • Old electric to modern electric hot water system with solar: save roughly $200–$500 per year.
Of course, every hot water system price / cost depends on the size, brand and complexity of the hot water installation. A premium Sanden heat pump or best heat pump hot water system will usually cost more upfront than a basic electric unit, but the heat pump hot water price / cost is often offset by lower bills and generous incentives. Likewise, solar hot water price / cost can look higher at first, but the long term savings from a well designed solar hot water heating system can be impressive.
Hot Water Rebates, Tariffs & Savings
Across Rewan QLD, more people are asking whether to replace old gas hot water with a heat pump or solar hot water, or to move from a failing cylinder to a modern electric hot water system that works better with solar. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump hot water and solar hot water systems, effectively acting as a solar hot water rebate or heat pump hot water rebate that reduces the upfront cost. On top of that, Queensland hot water rebate programs and occasional electric hot water system rebate offers can further bring down the final heat pump hot water price / cost or solar hot water price / cost.
For many Rewan households, these discounts can shave a significant percentage off the installed cost and cut payback times to just a few years, especially if you already have solar and use timers or smart controls to run your electric hot water system when the sun is shining. With the right setup, a solar hot water vs electric hot water comparison often shows hundreds of dollars a year in savings, and electric hot water vs gas hot water usually favours efficient electric, particularly on modern tariffs.
Whether you need hot water repair for an older unit, a full solar hot water repair, or you are planning a complete solar hot water tank replacement, it pays to think about the long term. The best heat pump hot water system or solar hot water system for your home is the one that balances upfront cost, rebates, running costs and reliability.
