Rebates
Hot Water
If you’re considering heat pump hot water in Victoria, rebates can take a meaningful amount off the upfront cost.

Eligible households may receive up to $1,000 through Solar Victoria, or up to $1,400 for an eligible locally made system,1 alongside a Victorian Energy Upgrades discount and federal Small-scale Technology Certificates (STCs).
But the rebate headline is only part of the story. What you actually pay depends on the system, what you’re replacing, the installation and which incentives apply.
This guide explains how the rebates fit together, what affects your installed price, and what to check before choosing a system or installer so you can compare the real cost and upgrade with confidence.
Victorian households can potentially reduce the cost of an eligible heat pump hot water system through three separate incentive mechanisms:
What Rebates and Discounts Can Reduce the Cost?
| Incentive | What it does | Current figure |
|---|---|---|
| Solar Victoria Hot Water Rebate | Rebate paid to the retailer and deducted from your invoice | Up to $1,000, or $1,400 for an eligible locally made product |
| Victorian Energy Upgrades (VEU) | Upfront discount generated through the VEU program | Indicatively $560 replacing inefficient gas with a heat pump, or $630 replacing inefficient electric hot water |
| Small-scale Technology Certificates (STCs) | Federal certificate incentive usually assigned for an upfront discount | Varies by eligible model, location and installation date |
Solar Victoria calculates its hot water rebate after other discounts, including STCs and Victorian Energy Efficiency Certificates, have been applied.
The rebate is then 50% of the eligible product purchase price, capped at the applicable $1,000 or $1,400 maximum.
If an eligible locally made product has a qualifying purchase price of $2,800 after applicable STC and VEU discounts, 50% is $1,400, so the Solar Victoria component could reach its $1,400 cap.
If a non-locally-made eligible product had the same $2,800 qualifying price, its Solar Victoria component would be capped at $1,000.
The Victorian Government says installed water heaters can range from $2,500 to $7,500 before incentives, so the headline rebate alone cannot tell you your final cost.2
As another market reference, the July 2026 price index puts the average Victorian heat-pump hot-water system at $4,392 including basic installation and STCs, before Victorian state rebates are applied.3
However, your actual out-of-pocket amount deserves its own calculation based on system, old hot-water type and installation.

While government rebates and incentives can help make heat pumps more affordable, the upfront cost can still be higher than traditional heating systems.
For many homeowners, this can make the final price feel difficult to justify. So, what actually drives the installed cost of a heat pump?
Let’s explore:
The cheapest system is not good value if it cannot meet your household’s hot-water demand.
Victorian Government guidance recommends considering both tank capacity and how quickly the heat pump reheats the water.
Here’s a size guideline:
| Household Size | Number of People | Government-recommended tank-size guide |
|---|---|---|
| 1-2 bedrooms | 1-2 people in small households | 150-225 L |
| 3 bedrooms | 3-4 people in growing families | 225-300 L |
| 4+ bedrooms | 5+ people with high hot water demand | More than 300 L |
However, these are starting points, not exact sizing rules.
Several factors, such as long or back-to-back showers or baths, inefficient showerheads, and the system’s recovery rate, can all affect the size you need.
Heat-pump prices vary substantially. The VEU buyer guide puts pre-incentive installed water-heater costs broadly at $2,500–$7,500, while noting differences in efficiency, quality and warranty.
When comparing price levels, look for:
Also remember, manufacturer support and warranty terms can matter for years after the rebate has been claimed.
A straightforward replacement and a complex relocation should not cost the same for a Victorian household.
Price may change if work is needed on the electrical circuit, plumbing, system location, pipe insulation, or access. Solar Victoria also recommends that an electrician is required for the hot-water electrical circuit.4
Want to see every rebate on your quote, itemised? We’ll check what applies to your home.
To qualify for Solar Victoria’s hot-water rebate as a homeowner, you must own and live in the property. Your combined household income must be under $150,000 a year, and your property must be valued below $3 million.5
Eligibility criteria also include:
Previous Solar Homes recipients may apply again after moving, if the new property has not already received those rebates.
Different rules apply across Solar Victoria and VEU, and claimant circumstances matter.

If you’re using a heat pump hot water system in your Victorian home, the tips below can help reduce energy bills and maximise savings.
If you already have solar PV, your heat pump can be scheduled to heat water during the day, helping you use more of your own solar generation instead of drawing as much electricity from the grid.
Solar Victoria specifically recommends considering timer-equipped systems for greater solar self-consumption.6
That matters even more now that Victoria no longer has a regulated minimum feed-in tariff:
Since 1 July 2025, retailers have set their own feed-in tariffs, which cannot be below zero. Using your own solar can therefore be more valuable than automatically exporting it, depending on your retail plan.
The first step when buying a heat pump hot water system is to conduct thorough research. Ask your retailer to identify each applicable incentive separately.
Your quote should make it possible to see where STCs, VEU, and the Solar Victoria rebate have been applied, rather than presenting only a single final discounted price.
An oversized tank can cost more to purchase and operate, while an undersized system may leave your household without enough hot water.
As a rule of thumb, many sizing guides estimate hot-water use at around 50 litres per person per day, but actual needs vary depending on shower length, fixtures and household routines.7
So, choose a tank based on your household’s actual usage to maximise savings.
A large advertised rebate tells you very little about the quality of the equipment or installation.
Compare the final installed scope, warranty, expected performance, service support and what is excluded from the price.
A useful starting point for calculating your payback period is:
Simple payback = net installed cost ÷ annual energy-cost savings
For example,
If a household hypothetically paid $3,000 net and achieved $400 in annual savings, the simple payback would be 7.5 years.
The $400 figure is consistent with the Victorian Government’s statement that many households can save around $400 annually, but actual savings depend on usage and what system is being replaced.8
It’s a requirement that Heat Pump water heaters installed under VEU must have a minimum 5-year warranty.
However, that is the minimum qualifying standard, not necessarily the end of your comparison.
Before buying a heat pump, read all the mentioned conditions carefully. Victorian Government guidance warns that some warranties require scheduled servicing and may not cover labour costs.
A strong warranty is more useful when the manufacturer and installer have a practical service pathway if something goes wrong.
Modern heat pumps can be very quiet, as low as 45dB,9 similar to the gentle hum of a fridge, but placement still matters because they use a compressor and fan.
Experts recommend avoiding placing the unit close to bedrooms where possible; outside a kitchen or bathroom may be more suitable.
Good pipe insulation, electrical work and commissioning also help the system run efficiently and reliably.
Before comparing the bottom-line price, check that the quote identifies:
From 1 March 2027, replacing an ageing gas hot-water system will require a little more planning.
For instance, if a gas unit in an existing Victorian owner-occupied home breaks down and cannot be repaired, it will generally need to be replaced with an energy-efficient electric hot-water system, such as a heat-pump water heater.
Similarly, for rental properties, end-of-life hot-water systems will generally need to be replaced with an energy-efficient electric hot-water system, such as a heat-pump water heater.10
Got an ageing hot-water system?
Now could be a good time to explore your options. Getting quotes early means you can compare systems, costs and installation requirements before a breakdown turns the decision into an urgent one.
The best heat-pump quote is not automatically the one with the biggest rebate or lowest advertised changeover price.
It is the one that clearly shows what system you are getting, why it suits the home, what work is included, which incentives apply and what support you have after installation.

Solar Victoria currently offers up to $1,000, or up to $1,400 for an eligible locally made product. VEU and federal STCs may reduce the upfront cost further.
They can potentially apply to the same eligible installation. Solar Victoria specifically states that its rebate is calculated after other discounts, including STCs and Victorian Energy Efficiency Certificates.
Solar Victoria’s current interest-free loan is linked to the solar PV rebate, not its hot-water rebate. Heat-pump hot water receives the applicable rebate and other eligible discounts instead.
Under VEU, water-heating upgrades have a minimum customer contribution of $200 including GST, and products cannot be offered or installed free under that program.
Victorian Government guidance gives a broad installed range of $2,500–$7,500 before incentives. System quality and installation requirements can move the final price substantially.
No. Rooftop solar is not listed as a requirement for Solar Victoria’s hot-water rebate. Solar can, however, improve the economics by letting a suitably controlled heat pump use daytime solar generation.
VEU-eligible heat-pump water heaters need at least a five-year warranty. Check the exclusions, servicing conditions, labour coverage and local support as well.
From 1 March 2027, an existing Victorian home’s gas hot-water appliance generally needs an electric replacement when it breaks and cannot be repaired. The rule does not mean every working gas unit must be removed on that date.
