Hot Water Systems in Calwell
The 2905 postcode, covering Calwell, Bonython, Chisholm, Gilmore, Isabella Plains, Richardson and Theodore and surrounding areas, is home to around 10,741 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 Calwell and the 2905 area, 516 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 Calwell'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.

Community Hot Water Statistics - Calwell, 2905
Hot Water Demographics - Calwell
Based on the Australian Bureau of Statistics 2021 Census (ABS), Calwell has around 10,741 private dwellings, home to approximately 27,631 people. With an average household size of 2.7 people, and around 50 litres of hot water used per person each day in Australia, Calwell households use approximately 135 litres of hot water daily, equating to a massive 1.5 million litres of hot water used across the suburb every single day.
Other census insights reinforce Calwell's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Calwell community is home to 2,556 couple families with children and 704 one-parent families, meaning a large proportion of households face substantial hot water demand. With 5,035 homes owned with a mortgage and 2,945 owned outright, many residents also have the homeownership and growing equity that make switching to efficient hot water systems a practical way to lower expenses.
Calwell is converting hot water demand to efficient systems faster than many peers, with 4.8% of dwellings already upgraded.
Hot water systems in Calwell
Across Calwell and the 2905 area, more households are swapping old gas and power‑hungry electric units for an energy efficient hot water system that keeps bills down without sacrificing comfort. With an average household size of about 2.7 people and more than 10,000 dwellings, reliable hot water is a daily essential – and rising energy prices mean your choice of hot water system really matters.
Calwell’s mostly separate houses and townhouses, many owned with a mortgage, are ideal for solar and efficient upgrades. The local median household income is strong enough that families are looking for long‑term savings, not just the cheapest hot water system price on the day. Upgrading from older gas or electric hot water to a modern heat pump hot water system, solar hot water system or efficient electric hot water system can cut the energy used for water heating by more than half, delivering substantial Annual Hot Water Energy Savings for typical Calwell homes.
The local climate helps. Nearby Theodore records an average annual solar exposure of about 17.1 MJ/m² per day – roughly 4.75 kWh/m² of sunshine – which is excellent for both a solar hot water heating system and a high quality heat pump hot water system. That strong solar input supports consistent performance from rooftop collectors and gives heat pumps plenty of mild daylight hours to draw low‑cost heat from the air.
In Calwell, most homes are three or four bedrooms, so hot water demand is solid, especially for families with teens and younger kids. Many households still run older gas or resistive electric units, so hot water energy use can be one of the biggest chunks of the power bill. Moving to the most efficient hot water system you can reasonably afford – whether that is a Sanden heat pump, Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water or a quality Chromagen solar hot water package – can make a real dent in bills while improving comfort.
Typical annual savings for 2905 homes look like this:
• Old electric to heat pump hot water installation: save around $350–$700 per year • Gas to heat pump: save roughly $250–$600 per year • Gas to solar hot water installation: save about $200–$550 per year • Old electric to modern electric hot water installation paired with rooftop solar: save around $250–$500 per year
Over the years, Calwell has already seen 516 efficient hot water installations, combining heat pump and solar hot water installation projects. Install numbers climbed steadily through the 2000s, peaking around 2009–2011 when more than 200 systems went in over just three years, before tapering to a steady trickle more recently. That early wave of installs shows how strongly locals responded to rebates and the first push towards electrification and lower running costs. The quieter recent years suggest a lot of those older systems are now coming due for hot water repair or solar hot water tank replacement – a timely moment to compare heat pump vs solar hot water and even solar hot water vs electric hot water to see what now stacks up as the best hot water system Australia for your home.
When it comes to hot water ACT homeowners also have a growing range of incentives to tap into. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively working as an upfront discount on the solar hot water price / cost or heat pump hot water price / cost. On top of that, ACT and federal programmes regularly offer a solar hot water rebate, heat pump hot water rebate and even electric hot water system rebate options that can bring the installed hot water system cost down by a substantial percentage.
For many Calwell families juggling mortgages of around $2,000 a month or rents of about $430 a week, those incentives can turn a three‑ to seven‑year payback into something much shorter, especially if you already have rooftop solar. Using timers, smart controls or solar diversion to run an electric hot water system during the middle of the day can slash running costs further, and make an energy efficient hot water system a key part of an all‑electric home that has moved beyond electric hot water vs gas hot water debates.
Whether you need fast hot water repair, are comparing heat pump vs solar hot water, or simply want a straight‑forward electric hot water installation, it pays to work with experienced local specialists. Calwell’s strong solar resource and community interest in sustainability mean efficient hot water systems can seriously reduce bills, cut emissions and future‑proof your place. If you are wondering whether your current unit is due for an upgrade, now is a smart time to explore options like a new heat pump hot water installation, solar hot water repair or full solar hot water tank replacement. Connect with trusted local experts for personalised advice on hot water ACT rebates, hot water rebate ACT incentives and the right system design for your home, and make your next hot water installation one that works harder for your wallet and the planet.
