The 5131 postcode, covering Houghton, Lower Hermitage and Upper Hermitage and surrounding areas, is home to around 354 households. 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 Houghton and the 5131 area, 86 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 Houghton's climate delivering an average of 4.8 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.

Hot water systems in Houghton
In Houghton, more locals are rethinking their old gas and electric hot water systems and switching to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With mostly separate houses, a high rate of home ownership and an average household size of 2.9 people, hot water demand in 5131 is steady – and so are the savings on offer when you upgrade.
The hills climate here is ideal for efficient hot water. At nearby Inglewood, the average annual solar exposure is around 17.1 MJ/m² per day, which works out to roughly 4.75 kWh/m² of sun each day. That strong sunlight helps both a solar hot water heating system and a quality heat pump hot water installation run efficiently, especially when paired with rooftop solar. For many Houghton households with solid median household incomes, moving from older gas or electric units to the most efficient hot water system they can afford is a logical next step to cut bills and emissions.
Across the 354 dwellings in the postcode, families and downsizers alike are looking for a reliable hot water system with a sensible hot water system price. Many homes still rely on gas or older resistive electric hot water, which can be one of the biggest energy users in the house. Swapping to an energy efficient hot water system – whether that is a sanden heat pump, a rheem heat pump hot water unit, or a roof‑mounted rinnai solar hot water or chromagen solar hot water system – can trim usage dramatically while keeping showers hot.
In Houghton 5131, hot water energy use can easily be a quarter or more of the total household bill, so the upgrade maths stacks up. Typical annual bill savings can look like:
• Old electric to heat pump hot water system: save about $400–$800 per year. • Gas to heat pump hot water: save roughly $300–$600 per year. • Gas to solar hot water system: save around $250–$550 per year. • Old electric to modern electric hot water installation with solar: save about $300–$700 per year.
Local homes often choose brands recognised in the conversation about the best hot water system Australia can offer, including Rheem solar hot water options, Rinnai solar hot water, and premium heat pumps like Sanden. For some households, the best heat pump hot water system will be a quiet, high‑efficiency unit that can run mostly on daytime solar, turning an electric hot water system into a low‑running‑cost solution. Others opt for a solar hot water vs electric hot water comparison and decide a solar hot water installation with a well‑sized solar hot water tank replacement offers the best long‑term value.
Recent data shows 86 efficient hot water systems – mainly heat pump and solar hot water installations – have already been installed across the 5131 postcode. Installations peaked in the early 2000s, with steady numbers through 2008–2010, and a smaller but ongoing trickle of upgrades through to 2025. That trend reflects growing interest in electrification, lower running costs and reliable hot water repair and hot water installation services in Houghton.
Hot Water Rebates, Tariffs & Savings
With rising energy prices, more Houghton homeowners are weighing up heat pump vs solar hot water, and even modern electric hot water vs gas hot water, to find the right fit. The good news is that several Australian Government incentives and state hot water rebate SA programs can bring the effective hot water system cost down. Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, acting like an upfront discount. On top of that, South Australian schemes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when replacing old, inefficient units.
These incentives can trim the heat pump hot water price or solar hot water price by a substantial percentage, often cutting thousands off the installed cost. When you then factor in bill savings of hundreds of dollars per year, the payback period for a hot water upgrade in Houghton can shrink to just a few years, especially if you use timers or solar‑diversion controls so your energy efficient hot water system heats mainly during sunny, off‑peak times.
If you live in Houghton and your existing unit is ageing, noisy or expensive to run, it is a great time to check whether your home is ready for a hot water upgrade. Whether you are moving from gas to an all‑electric home with a heat pump, or comparing solar hot water vs electric hot water, working with experienced local hot water installers and repair specialists matters. With Houghton’s strong solar resource and growing interest in sustainability, an efficient hot water system can help reduce bills, cut emissions and future‑proof your property.
