HEAT PUMP HOT WATER WITH SOLAR: THE ULTIMATE GUIDE FOR ADELAIDE & MELBOURNE
Tired of high energy bills? Discover why thousands of Australian homeowners in Adelaide and Melbourne are switching to Heat Pump Hot Water Systems — the smarter, more sustainable choice when paired with solar power.
Heat pump hot water systems are quickly becoming the go-to solution for efficient, eco-friendly hot water – especially when paired with solar energy. In the last year alone, installations of heat pump hot water systems in Australia jumped by 70%, thanks to improved performance and generous rebates.
Homeowners and facility managers (from suburban Adelaide to metropolitan Melbourne) are eyeing these systems as a replacement for ageing electric or gas heaters. This guide breaks down everything you need to know – how heat pumps work, why they're ideal with solar, what incentives are available, and how Jousto's smart Energy Hub can amplify your savings.
WHY HEAT PUMPS ARE THE FUTURE OF HOT WATER
MASSIVE ENERGY SAVINGS
Modern heat pump water heaters use up to 70% less electricity than traditional electric resistance systems. Instead of generating heat from scratch, they harvest ambient heat from the air to warm your water.
This high efficiency means lower energy bills – often reducing water heating costs by 50–70% compared to old electric or gas units. In real terms, many households see hundreds of dollars in annual savings.
STRONG ROI
Thanks to energy savings and rebates, a quality heat pump can pay for itself in as little as 3–5 years. Melbourne's climate, for instance, allows year-round efficient operation, and rebates can cut upfront costs by $1,000–$2,000.
Homeowners typically recoup their investment within a few winters of lower bills. In South Australia, bill reductions of ~18–30% are common when replacing old systems.
ECO-FRIENDLY PERFORMANCE
Every heat pump installed helps cut greenhouse emissions. By using renewable heat from the air, heat pumps slash carbon output versus gas burners or coal-powered electric tanks.
For environmentally conscious consumers – including community housing projects and NDIS facilities aiming for sustainability – this is a big win. Heat pumps also avoid gas combustion entirely, eliminating risks of gas leaks or toxic emissions.
WIDE ADOPTION & RELIABILITY
The technology is proven – over 150,000 units are installed across Australia, from homes to aged care centres, with that number growing fast. Premium brands offer long warranties (often 10–15 years on tanks).
Well-maintained units can last over a decade. Users on forums often ask if heat pumps last; the answer is yes – a lifespan of 10–15 years is typical, rivalling traditional heaters.
PERFECT FOR ELECTRIFICATION
As Australia moves towards full home electrification, heat pumps are a crucial component. They allow homeowners to eliminate gas connections entirely, creating an all-electric home that can be powered by renewable energy.
This transition is supported by government policies and rebates, making it financially attractive to switch from gas to electric heat pump systems as part of a broader sustainability strategy.
SMART INTEGRATION
Modern heat pumps can be integrated with home energy management systems like Jousto's Energy Hub. This allows for intelligent operation based on solar production, electricity prices, and household usage patterns.
The ability to time operation during periods of excess solar production or low grid prices maximises savings and minimises environmental impact, making heat pumps a smart choice for the connected home.
HOW HEAT PUMP HOT WATER SYSTEMS WORK
A heat pump hot water system works like "a reverse refrigerator." Instead of cooling air, it extracts heat from the air and pumps that heat into water:
- Evaporation: A fan draws in outside air over refrigerant coils. Even if the air is cool, the refrigerant absorbs its heat (heat pumps can pull useful energy from air as cold as -10°C in premium models).
- Compression: The refrigerant (now a warm gas) is compressed, raising its temperature significantly.
- Heat transfer: The hot refrigerant passes through a heat exchanger around the water tank, transferring heat to the water. The refrigerant cools and turns back into liquid, ready to repeat the cycle.
- Result: The water in the insulated tank heats up to the set temperature (typically ~60°C). This process is powered by electricity, but for every 1 kWh of electricity, a heat pump can deliver 3–5 kWh of heat to your water.
This Coefficient of Performance (COP) of 3–5 means free heat from the environment provides the majority of the energy.
The outcome? Lots of hot water for a fraction of the energy. For example, 1 kW of input can yield ~5 kW of heating – a 500% output – in top models. This efficiency holds especially well in mild climates like Adelaide and Melbourne, making heat pumps an excellent fit for both regions.
BENEFITS OF PAIRING HEAT PUMPS WITH SOLAR
One of the biggest advantages of heat pump systems is how seamlessly they integrate with solar PV panels. If you have solar (or plan to add it), a heat pump maximises your solar investment:
- Use solar power you'd otherwise export: Rather than send excess midday solar generation to the grid for a low feed-in tariff, you can run your heat pump to store that solar energy as hot water. Essentially, your water tank becomes a thermal battery – you're bottling sunshine to use for your evening shower.
- Reduce grid reliance: Running the heat pump during peak solar hours or when wholesale prices are low means you draw little to no electricity from the grid for water heating. This can drive your bills down further, especially in summer when solar output is high.
- Smart scheduling: Heat pumps can be set on timers or controlled via smart systems to operate when solar is available. Jousto's Energy Hub takes this to the next level by automating your heat pump to run at optimal times – for instance, when your solar is at peak or even during negative-price events on the grid.
- Eliminate gas entirely: For homes switching from gas, combining solar PV with a heat pump means you've now fully electrified hot water with zero on-site emissions. No more gas bills or the daily gas supply charge – just free or cheap solar-heated water.
MISCONCEPTION CLEARED
"I already have solar hot water, do I need a heat pump?"
Traditional solar thermal hot water systems use roof collectors and often have electric/gas boosters. They save energy, but heat pumps can actually be more efficient and flexible.
A heat pump doesn't require clear roof space or plumbing to the roof, and it works day or night (storing energy when it's cheapest). Many homeowners are now replacing old solar thermal systems with heat pumps for greater year-round savings, simplicity, and better integration with home energy management.
ADELAIDE VS. MELBOURNE: CLIMATE AND INCENTIVES
Both Adelaide and Melbourne see strong interest in heat pump hot water, but there are local nuances:
ADELAIDE (SOUTH AUSTRALIA)
Adelaide's Mediterranean climate (warm summers, mild winters) is ideal for heat pumps. Even in cooler months, daytime highs are usually sufficient for efficient operation. Quality heat pumps in SA operate effectively down to -10°C – and Adelaide rarely gets that cold.
South Australians also enjoy robust incentives: under the REPS (Retailer Energy Productivity Scheme) (formerly REES) and federal programs, you can get big discounts. The City of Adelaide, for example, offers rebates up to $1,000 for solar hot water heat pumps.
Combined with federal Small-scale Technology Certificates (STCs), total incentives can reach $2,000+ for eligible installations. The result? Many Adelaide homeowners replace old electric tanks for little out-of-pocket cost.
MELBOURNE (VICTORIA)
Melbourne's temperate climate includes colder winters, but modern heat pumps handle this well. It's true that cheap models struggle below ~5°C, kicking in an electric booster and losing efficiency. However, high-COP units (and CO₂ refrigerant models) thrive even in chilly conditions.
For Melbourne residents, the economic case is boosted by generous rebates: You can combine three different incentives – federal STCs (worth ~$600–$800), Victorian Energy Upgrades (VEEC, $420–$780), and Solar Victoria's heat pump rebate ($1,000) – for a total of up to $2,600 off.
This "double-dip" rebate opportunity in VIC is a major reason heat pumps are booming. With the rebates, many Victorians find a quality 250L–315L heat pump costs under $1,500 out-of-pocket.
INCENTIVES SNAPSHOT
In summary, both SA and VIC offer strong support:
- South Australia: Federal STC (~$700), SA state programs (up to ~$1,000 or more via REPS), plus City of Adelaide bonus ($500–$1,000) – combining to potentially $1,500–$2,000+ in aid.
- Victoria: Federal STC (~$700), VEEC (~$400–$800), Solar Victoria $1,000 – totalling up to $2,600 off your system. This often covers 40–60% of a mid-range system's cost.
Both regions also allow interest-free loans or financing on solar/energy upgrades in certain cases, which can further ease the upfront cost. Always check the latest local programs, as these incentives can update year to year.
COSTS AND SAVINGS: WHAT TO EXPECT
UPFRONT COST
Without any rebates, heat pump hot water systems typically range from about $2,000 to $5,000 for the unit itself (smaller 170L–200L units on the lower end, premium 300L ones on the higher end). Installation costs can add $600 to $1,400, depending on complexity.
- Swapping a similar electric tank in the same spot is straightforward, keeping install costs around the low end (~$700).
- Converting from gas to electric heat pump is more involved – it needs a new circuit from the switchboard and safe decommissioning of gas lines. This scenario may hit the higher install range (~$1,200 or more).
- Additional factors like difficult access, moving the unit's location, or upgrading old plumbing can add cost.
After federal STC rebates (which nearly everyone gets instantly as a discount), the average price for a heat pump upgrade in Australia is around $4,150 including basic installation. In SA and VIC, applying state rebates brings typical out-of-pocket costs to ~$1,500–$2,500 for many homeowners.
RUNNING COSTS
Here's where heat pumps shine. A family of four with a traditional electric water heater might spend $800+ a year on water heating. A heat pump could slash that by around 2/3.
In fact, data from Sustainability Victoria comparing water heater types showed heat pumps as the cheapest to run annually. By consuming ~70% less energy, many users save $300–$500 per year on energy bills just from hot water.
If you have solar and run the heat pump mostly on solar power, your effective hot water energy cost could drop to nearly zero on sunny days.
Example: One Reddit user in Melbourne noted their heat pump cut their peak electricity use dramatically, and with rebates the system cost was nominal. Similarly, a Whirlpool forum member in Perth calculated that even with conservative settings, a heat pump paid for itself in about 4 years via bill savings – making it absolutely "worth it."
MAINTENANCE AND LIFESPAN
Heat pumps are low-maintenance. They have a fan and compressor (like an AC unit) which should be kept clear of debris. Many have sacrificial anodes in the tank to check every few years (like any storage tank).
In general, they don't require frequent servicing. Warranties often cover 5+ years on the compressor and 10+ on the tank, indicating manufacturer confidence.
Over 10–15 years, you might replace a fan or sensor, but those costs are minor compared to the savings reaped.

TOP 10 FAQ ABOUT HEAT PUMP HOT WATER
Here are ten frequently asked questions we often hear from Adelaide and Melbourne customers regarding heat pump hot water systems – along with concise answers:
Yes – thanks to big energy savings and rebates, heat pump systems are absolutely worth it. They use ~70% less power than old electric heaters, so you save on bills. Both SA and VIC offer incentives (up to $2k–$2.6k) that cut purchase costs.
In Adelaide's mild climate and Melbourne's well-supported market, a quality heat pump often pays for itself within 3–5 years. After that, it's money in your pocket every year.
They work by extracting heat from the air. A fan pulls in outside air, a refrigerant absorbs the air's heat, then a compressor concentrates that heat and transfers it to the water in the tank. It's the reverse of how a fridge cools.
Because they move heat rather than make it, they're super efficient – 1 unit of electricity can generate 3–5 units of heat in your water. Even in cold weather, there's enough ambient heat for the system to work (down to around -10°C for good models).
Yes, absolutely. In fact, pairing with solar is ideal. You can set the heat pump to run during the day to use your solar PV's excess energy. This means your hot water is heated "for free" by the sun.
Jousto's Energy Hub can automate this, turning on the heat pump exactly when your solar output is highest. With solar, many customers find their electric bill for hot water drops to near zero on average. It's a perfect combination for reducing grid usage and maximising solar self-consumption.
There are generous rebates in Australia:
- Federal STC incentive: Worth roughly $600–$800 off upfront (applied as a discount by installers in most cases).
- South Australia: Under REPS, many households qualify for additional discounts (often $500–$1,000 value), and City of Adelaide residents get up to $1,000 rebate.
- Victoria: You can stack three incentives – STC, Victorian Energy Upgrade (VEEC ~$500), and Solar Victoria's $1,000 rebate – totalling up to $2,600 in rebates.
These significantly lower the cost of a heat pump system. Check local eligibility (often if replacing an electric unit, you qualify; replacing gas has slightly different rules). Jousto helps clients navigate and claim all applicable rebates.
After rebates, most people pay around $1,500 to $3,000 out-of-pocket for a good system, including installation. The exact cost depends on the unit size/brand and installation complexity.
For example, a 250L unit might be $2,500 for the system and $800 for install = $3,300, minus say $1,500 in rebates → ~$1,800 net cost. Without any rebates, a high-end system plus install could be around $5,000.
The average national installed cost is ~$4,157 before state rebates. It's higher than a basic electric heater, but remember the running costs are far lower – so the investment pays back over time. Jousto provides upfront quotes showing the full price and then any rebates you're entitled to, so you see the final cost clearly.
Yes, modern heat pumps are designed to work year-round. In winter, they do run longer and a bit less efficiently (because the air is colder), but they will still heat your water.
For instance, many units that have a COP of 4 in summer might drop to COP 2–3 in cold winter nights – meaning they're still 200–300% efficient (2–3 times more efficient than a traditional heater).
In places like Melbourne where winter nights can approach 0°C, it's important to get a unit with good low-temp performance. Some models have a built-in electric booster that kicks in only if needed on the chilliest nights, so you never go without hot water.
As long as your unit is sized right, you won't notice any difference in availability of hot water in winter – just possibly a slight uptick in electricity use compared to summer (still much less than an electric tank would use).
They're pretty quiet. The sound comes from a fan and compressor, similar to a small air conditioner. Typically, noise levels range from 37 dB to 50 dB. 37 dB is very quiet – like a whisper or a refrigerator humming in the next room. 50 dB is a bit louder, like moderate rainfall.
Most units will be closer to the 45 dB mark. In practice, customers rarely complain about noise. If the unit is outside or in a garage, you might not hear it at all indoors. If near a bedroom window, you might hear a faint hum when it's running – but remember, it doesn't run constantly; once the water's heated, it turns off.
If noise is a concern, Jousto can recommend ultra-quiet models and placement that minimises any disturbance.
On average about 10 to 15 years, which is similar to or a bit longer than a conventional electric or gas tank. The tank portion is like any other hot water tank (glass-lined steel) and often comes with a 10-year warranty. The heat pump mechanism (compressor, etc.) might have a 5-year warranty on parts.
With proper maintenance (flushing the tank if needed, replacing anodes every few years in hard water areas), some heat pumps have been known to last 15+ years. It's good to check warranty terms of the brand you choose: e.g., Sanden offers 15 years on the tank and 6 years on the compressor, which indicates the expected longevity for high-end systems.
Jousto only installs reputable brands with solid support, so you're covered long-term.
Yes, definitely. Converting from gas to a heat pump is a common upgrade, especially as homes move towards all-electric setups. The installer will safely cap off the gas line and you might even be able to remove the gas meter eventually (saving on supply charges).
The main difference for install is running an electrical circuit to power the heat pump – Jousto handles the necessary electrical work with licensed electricians. Once installed, you'll enjoy not just lower energy bills but also the elimination of gas appliance maintenance and the improved safety of having no gas combustion in the home.
Plus, many state rebates (like in VIC) apply a bonus when switching from gas to efficient electric, because it helps reduce emissions. So you get help with the cost. In short, gas to heat pump is a wise switch that many are doing in Adelaide and Melbourne.
Jousto combines expert installation with smart technology that others don't offer. When you get a heat pump hot water system from Jousto, we don't just set and forget it – we integrate it with the Jousto Energy Hub, which intelligently controls when the heat pump runs to maximise use of solar or off-peak power.
No other provider in SA or VIC is currently offering this level of automation for hot water. Essentially, with Jousto you get:
- Top-quality heat pump unit (we'll help choose the right brand/model for you).
- Professional installation by our team (plumbing and electrical included, no fuss).
- Smart Energy Hub controller that links your heat pump to your solar system or tariff data, optimising your energy use in real-time.
- Ongoing support and monitoring – we ensure your system runs smoothly and you get the savings promised.

Introduction: The Convergence of Clean Energy and Smart Technology
The increasing adoption of residential solar power, battery storage, and electric vehicles (EVs) is revolutionising how energy is generated, stored, and used in the home. However, without intelligent coordination, these technologies often operate independently—missing key opportunities for efficiency and cost savings. This is where smart energy automation steps in.
Smart energy automation enables homeowners to manage all aspects of their energy ecosystem—generation, consumption, and storage—from a single, intelligent control system. By integrating solar PV systems, home batteries, EV chargers, and smart appliances, these solutions can optimise energy flows in real time.
This blog explores how smart energy automation is reshaping home energy management, covering its core concepts, technologies, market-leading products, key benefits, and challenges. It also outlines the companies and systems driving innovation in this space.
Main Concepts and Applications of Smart Energy Automation
Intelligent Energy Flow Management
At its core, smart energy automation is about managing where and when energy is used, stored, or exported. A smart energy system might decide to:
Power appliances directly from solar during the day,
Store excess energy in a home battery,
Use stored energy at night or during peak tariff times,
Or schedule EV charging based on solar availability.
This approach maximises self-consumption, reduces electricity bills, and improves energy independence. Solutions like SolarEdge Home enable dynamic control over energy sources and consumption, allowing the home to become a self-sustaining energy hub.
Optimised Charging and Discharging
Smart automation can optimise the charging of batteries and EVs to occur during:
Peak solar generation,
Off-peak tariff windows,
Or ahead of forecasted high-energy use periods.
For example, Home Assistant users commonly set up automations that delay battery charging until overnight rates apply or only charge the EV when solar production is high. This results in dramatic cost savings and a reduced carbon footprint.
Load Management and Prioritisation
During grid outages or when battery charge is low, load prioritisation ensures critical devices (like medical equipment or fridges) continue to run, while non-essentials (like pool pumps or entertainment systems) are shut off.
SPAN smart panels take this further by giving users appliance-level control over circuits. This kind of granular management extends battery backup time and ensures business-critical or life-critical systems remain online.
Remote Monitoring and Control
Mobile apps and cloud dashboards give homeowners complete visibility into their energy system:
Solar output
Battery charge levels
EV charging status
Appliance usage
Apps like mySolarEdge or the SPAN Home App allow real-time insights, system control, and even adjustments from anywhere in the world. This remote capability turns energy usage into a data-driven, user-friendly experience.
Key Technologies, Companies, and Smart Energy Products
Smart Inverters and Power Optimisers
Modern smart inverters go beyond energy conversion—they communicate with batteries, EV chargers, and home automation platforms. Market leaders like SolarEdge offer DC-optimised technology with panel-level performance data and control.
These inverters are crucial for coordinating how solar power is used:
