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 Haven and the 3401 area, 279 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 Haven's climate delivering an average of 4.7 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.

Community Hot Water Statistics - Haven, 3401
Hot Water Demographics - Haven
Based on the Australian Bureau of Statistics 2021 Census (ABS), Haven has around 1,854 private dwellings, home to approximately 4,269 people. With an average household size of 2.7 people, and around 50 litres of hot water used per person each day in Australia, Haven households use approximately 135 litres of hot water daily, equating to a massive 0.3 million litres of hot water used across the suburb every single day.
Other census insights reinforce Haven's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Haven community is home to 404 couple families with children and 52 one-parent families, meaning a large proportion of households face substantial hot water demand. With 609 homes owned with a mortgage and 785 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.
Haven is converting hot water demand to efficient systems faster than many peers, with 15.0% of dwellings already upgraded.
Hot water systems in Haven
In Haven, more locals are swapping old gas and electric tanks for energy efficient hot water systems that keep bills down without sacrificing comfort. With most of the 1,581 dwellings being separate houses and an average household size of 2.7 people, hot water demand is steady year‑round. Rising energy costs and solid median household incomes mean upgrading to a modern hot water system is a logical next step for many families looking to rein in running costs.
Haven’s climate is ideal for efficient hot water. The nearby Horsham weather station records around 16.9 MJ/m² of solar exposure annually – roughly 4.7 kWh/m² per day – which gives a solar hot water system or heat pump hot water system plenty of free energy to work with. That strong sunlight, combined with good roof space on local homes, makes solar hot water heating system options very attractive, especially if you already have rooftop solar.
Across the 3401 postcode, households are typically paying off a mortgage or have already paid off their home, so thinking long term about the most efficient hot water system makes sense. Annual hot water energy savings can be substantial when you move from an old electric hot water system or gas unit to a quality heat pump hot water system or solar hot water system, especially for busy family homes that are shower‑heavy.
In Haven, we see a mix of systems to match different home sizes and budgets. Three‑ and four‑bedroom homes are common, so 250–315 litre heat pump hot water installation or solar hot water installation suits many families, while downsizers and older couples often lean towards smaller electric hot water installation with smart controls. Brands like Rheem heat pump hot water and Rheem solar hot water are popular for their reliability, while Sanden heat pump units are well regarded for efficiency and quiet operation. Rinnai solar hot water and Chromagen solar hot water systems also appear regularly on roofs around the district, especially where owners want to maximise their solar hot water rebate and cut daytime grid use.
Typical annual bill savings in Haven for an energy efficient hot water system can look like:
• Old electric to heat pump: $400–$800 per year • Gas storage to heat pump: $300–$600 per year • Gas storage to solar hot water: $250–$550 per year • Old electric to modern electric with solar: $200–$450 per year
Recent data shows 279 efficient hot water installations (heat pumps and solar hot water) recorded in the 3401 area. Installations jumped sharply around 2008–2011, with 31 systems in 2008 and 43 in 2009, then steady numbers through the 2010s and a fresh lift to 12 installs in 2022. This trend reflects growing local interest in electrification, lower running costs and moving away from gas hot water in favour of heat pump hot water and solar hot water vs electric hot water alone.
When comparing heat pump vs solar hot water, many Haven homeowners weigh up roof space, orientation and budget. A heat pump hot water system price / cost is often lower upfront than a full solar hot water heating system, and it works well even on cloudy Wimmera days. Solar hot water price / cost can be higher initially, but if you have good north‑facing roof and a decent solar hot water rebate, the long‑term savings can be excellent. For some, the best heat pump hot water system paired with rooftop solar offers a great balance of flexibility and efficiency. Others prefer a robust solar hot water tank replacement with electric boost to stay mostly off gas. Either way, the aim is an energy efficient hot water system that fits your household’s pattern and budget.
Hot water repair and maintenance also matter. Locals in Haven often call for solar hot water repair when an older rheem solar hot water or rinnai solar hot water unit starts to struggle, or for hot water repair on older electric cylinders. Knowing your hot water system price / cost over its lifetime, including servicing, helps you decide whether to repair or replace.
Electric hot water vs gas hot water is another big question. With Victoria’s push towards all‑electric homes and more rooftop solar, many Haven households are choosing efficient electric hot water system options such as heat pumps instead of replacing old gas. The combination of lower emissions, better tariffs and improved control (like timers to run when solar is generating) often makes electric the smarter long‑term choice.
Hot Water Rebates, Tariffs & Savings
Across Victoria, including Haven, interest is growing in replacing tired gas or electric units with efficient options like heat pumps, newer electric hot water systems or solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively lowering the upfront heat pump hot water price / cost or solar hot water price / cost at the point of sale. On top of this, state‑based hot water rebate VIC programs can provide a specific heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when moving away from gas.
For many Haven households, these hot water rebate VIC schemes can cut the installed cost by a substantial percentage, turning a multi‑thousand‑dollar project into something much more manageable. When you factor in typical savings of hundreds of dollars per year on bills, the payback period can shrink considerably, especially if you combine an energy efficient hot water system with rooftop solar and use timers or solar‑diversion controls to heat water when the sun is shining.
If you are in Haven and your current unit is ageing, noisy or running up big bills, now is a good time to check whether a hot water VIC upgrade is right for you. Whether you are considering solar hot water vs electric hot water, a full solar hot water tank replacement or a switch to the best hot water system Australia can offer in a modern heat pump, it pays to get proper advice.
