The 2903 postcode, covering Wanniassa, Erindale Centre and Oxley and surrounding areas, is home to around 3,670 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 Wanniassa and the 2903 area, 277 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 Wanniassa'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. 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 Wanniassa
Across Wanniassa, more households are rethinking their hot water system and moving away from old gas and power‑hungry electric units. With most of the 3,500+ dwellings here being separate houses and an average household size of around 2.6 people, hot water demand is steady – and so are the running costs. For families juggling mortgages of about $2,100 a month and busy mornings before school and work, an energy efficient hot water system is a simple way to take the pressure off the power bill.
Wanniassa’s solar exposure is a real asset. The nearby Tuggeranong weather station records an average of about 17.2 MJ/m² of sunshine per day – roughly 4.8 kWh/m² – which is excellent for a solar hot water system or heat pump hot water system. That means a modern solar hot water heating system or quality heat pump can do most of the heavy lifting, with the booster only topping up in the coldest ACT mornings. For many local homeowners, especially the large number who own outright or with a mortgage, upgrading from older gas or resistive electric to a modern heat pump or solar hot water installation is the logical next step towards lower bills and smaller emissions.
In 2903, most homes are three‑ and four‑bedroom places, so showers, baths and laundry loads add up. Hot water can be 20–30% of a typical home’s energy use, which is why efficient systems are getting popular. Brands like Rheem heat pump hot water units and Sanden heat pump systems are common choices for those chasing the best heat pump hot water system, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water options suit homes with good roof space. For many, the best hot water system Australia‑wide is simply the one that balances upfront hot water system price with long‑term savings and reliability.
Typical annual bill savings in Wanniassa look like:
• Old electric hot water system → heat pump hot water system: save roughly $400–$800 per year. • Gas hot water → heat pump hot water system: save about $250–$600 per year. • Gas hot water → solar hot water system: save about $200–$500 per year. • Old electric → modern electric hot water installation powered by solar: save around $300–$700 per year.
Recent data shows 277 efficient hot water installations (heat pump and solar hot water) already completed in Wanniassa. Installations spiked around 2009–2011, when solar hot water rebate schemes were strongest, and there has been a steady trickle of new heat pump hot water installation jobs in the 2020s as residents focus on electrification and lower running costs. This trend reflects growing interest in solar hot water vs electric hot water, and in many cases, electric hot water vs gas hot water for all‑electric homes.
Hot Water Rebates, Tariffs & Savings
For Wanniassa homeowners, there is strong interest in replacing ageing gas systems with a high‑efficiency heat pump hot water system or solar hot water system, or even a well‑sized electric hot water system paired with rooftop solar. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively cutting the solar hot water price or heat pump hot water price at the point of sale. ACT‑based schemes and retailer offers can stack on top, acting like a hot water rebate act that lowers the upfront hot water system cost by a substantial percentage.
Depending on your usage and roof, an energy efficient hot water system can trim hundreds of dollars a year off bills and deliver payback in just a few years, especially when rebates and solar are combined. Using timers or solar diversion to run a heat pump during sunny hours can push you closer to the most efficient hot water system performance. There are also electric hot water system rebate programs from time to time that help people shift from gas to efficient electric.
Whether you need hot water installation for a renovation, hot water repair on a tired tank, or a full solar hot water tank replacement, it pays to compare heat pump vs solar hot water carefully. Many Wanniassa households find that a quality Rheem solar hot water or Rinnai solar hot water system is ideal if roof space and orientation are good, while a Sanden heat pump or similar premium unit is often the quiet achiever for shaded blocks or homes planning to maximise their solar PV.
