Heat Pump Hot Water Victoria 2026: Rebates, VEU & 2027 Gas Changes
If your hot water system is getting old, breaking down regularly or costing more to run than it should, 2026 is an important year to look at a heat pump hot water system in Victoria.
Victoria currently offers a Solar Homes hot water rebate of up to $1,000 for eligible products, or up to $1,400 for eligible locally made products. Eligible households may also be able to receive a Victorian Energy Upgrades (VEU) discount, reducing the upfront cost further.
There is also a major change coming.
From 1 March 2027, existing Victorian homes will need to replace gas hot water systems with an efficient electric alternative, such as a heat pump, when the existing gas system reaches end-of-life.
That does not mean every Victorian household needs to replace a working gas hot water system immediately. But if your gas system is already approaching the end of its life, waiting until it fails completely could leave you making a rushed decision.
A heat pump can also work particularly well with rooftop solar because its operation can be scheduled around periods of solar generation.
So the real question is not simply: "Should I get a heat pump?" It is: "Is a heat pump the right hot water solution for my home, and what rebates, VEU discounts and energy savings could apply in 2026?"
Your Situation, What to Consider
| Your Situation | What You Should Consider |
|---|---|
| Existing electric hot water | A heat pump may significantly reduce electricity consumption compared with conventional electric hot water |
| Existing gas hot water | Start planning before the system reaches end-of-life, particularly with the 2027 Victorian requirements |
| Gas system already failing | Investigate an efficient electric replacement rather than automatically installing another gas system |
| Existing solar | A heat pump can potentially be scheduled to use daytime solar generation |
| Solar + Midday Power Saver | The 11am–2pm free electricity period may provide another opportunity for scheduled hot water heating |
| Family of 4 | Correct tank sizing becomes important; avoid choosing a system simply because it has a larger tank |
| Small household | A smaller suitable tank may be more practical and economical |
| Looking for rebates | Check current Solar Victoria eligibility and eligible product lists before signing a contract |
| Looking for VEU discount | Use an authorised provider and confirm the exact product and activity are eligible |
| Building a new home | New Victorian homes must be all-electric from 1 January 2027 |
What Is a Heat Pump Hot Water System?
A heat pump hot water system uses electricity to move heat from the surrounding air into a storage tank. It is different from a conventional electric hot water system.
Conventional Electric
Electricity → heating element → water. Uses an electrical heating element to directly heat the water.
Heat Pump
Electricity → heat pump → heat from air → water. Uses refrigeration technology to extract heat from the surrounding air.
Because the heat pump moves heat rather than creating all the heat directly using an element, it can use substantially less electricity than a conventional electric hot water system. The Victorian Government's VEU buyer information states that eligible heat pump systems can use around 60–75% less electricity than conventional electric hot water systems.
Why Heat Pump Hot Water Matters in Victoria in 2026
1. Energy Efficiency
Hot water can represent around 15–30% of household energy use. Reducing the energy required to heat water can make a noticeable difference to household energy consumption.
2. Government Incentives
Eligible Victorian households may qualify for the Solar Homes hot water rebate of up to $1,000 (or up to $1,400 for locally made products). Eligible households may also receive a VEU discount when replacing an inefficient electric or gas hot water system with an eligible heat pump.
3. Victoria's 2027 Gas Hot Water Changes
From 1 March 2027, existing Victorian homes will need to replace gas hot water systems with an efficient electric alternative when the gas system reaches end-of-life. If your gas system is 8–12 years old, showing corrosion, producing inconsistent temperatures, frequently needing repairs, or approaching manufacturer end-of-life, 2026 is a sensible time to investigate your options.
How Much Is the Victorian Heat Pump Hot Water Rebate?
| Product Type | Rebate Amount |
|---|---|
| Standard eligible product | Up to $1,000 |
| Eligible locally made product | Up to $1,400 |
Solar Victoria describes the hot water rebate as a 50% rebate on the purchase price after other eligible discounts have been applied, subject to the maximum rebate amount. You should not simply take the advertised retail price and subtract $1,400. The actual rebate calculation depends on the eligible purchase price and applicable discounts.
Current Solar Victoria eligibility includes requirements such as:
- Being an owner-occupier of an existing property
- Combined household taxable income below $150,000 (from 1 July 2026)
- Property value below $3 million
- The property not having previously received certain Solar Homes rebates
- Replacing an existing hot water system that is at least three years old
- Selecting an eligible product
- Using an authorised hot water retailer
Can You Get a VEU Discount as Well?
Potentially, yes. This is one of the most important points when comparing heat pump quotes in Victoria.
The Victorian Energy Upgrades (VEU) program provides incentives for eligible energy-efficiency upgrades. Solar Victoria also states that eligible households can receive both the Solar Homes hot water rebate and the VEU hot water discount when the relevant eligibility and provider requirements are met.
The value of the VEU discount can vary because VEECs are market-based certificates. Avoid advertisements claiming that every household receives one fixed VEU rebate amount. Ask the provider for the actual discount applicable to your selected product and installation.
VEEC stands for Victorian Energy Efficiency Certificate. VEECs are generated through eligible energy-efficiency activities under the VEU program. The certificates represent greenhouse-gas savings associated with eligible activities. For homeowners, this usually appears more simply as "VEU discount" on an eligible quote.
Can You Combine Solar Victoria + VEU + STCs?
Potentially, yes, where the relevant program rules are satisfied. For eligible hot water systems, the available financial support can involve more than one mechanism.

Solar Victoria specifically states that its hot water rebate is calculated after other discounts, including STCs and VEECs, have been applied. This is why comparing only the advertised rebate amount can be misleading. What matters is the final installed price you actually pay.
Heat Pump vs Gas Hot Water
| Factor | Heat Pump | Gas Hot Water |
|---|---|---|
| Energy source | Electricity + heat from air | Gas |
| Electricity consumption | Generally lower than conventional electric | Low electrical use for many gas systems, but uses gas |
| Renewable-energy compatibility | Excellent with solar | Limited |
| Can use daytime solar | Yes | No direct solar-electric benefit |
| VEU eligibility | Eligible products/activities | Existing gas replacement rules are changing |
| 2027 Victorian direction | Supported | Gas systems at end-of-life must move to efficient electric alternative |
| Outdoor unit | Yes | Depends on system |
| Noise | Low but audible | Generally different operating characteristics |
| Upfront cost | Can be higher than basic electric | Varies |
| Long-term energy strategy | Suits electrified homes | Less aligned with full electrification |
The important point is not that every heat pump is automatically better for every home. The system needs to be correctly sized and installed.
Heat Pump vs Conventional Electric Hot Water
| Factor | Heat Pump | Conventional Electric Storage |
|---|---|---|
| Electricity consumption | Lower | Higher |
| Uses ambient heat | Yes | No |
| Solar integration | Excellent | Possible |
| Running cost | Potentially lower | Usually higher |
| Technology | Compressor + tank | Heating element + tank |
| Noise | Outdoor unit produces some noise | Generally very quiet |
| Installation | More complex | Simpler |
| VEU eligibility | Eligible systems | Depends on program/activity |
| Solar Victoria rebate | Eligible products | Current rebate focuses on eligible efficient systems |
The Victorian Government estimates that heat pumps can use 60–75% less electricity than conventional electric hot water systems. Actual results depend on the product and operating conditions.
Can a Heat Pump Run on Solar Power?
Yes. This is one of the strongest reasons to consider a heat pump if your home already has rooftop solar. Your system can be scheduled so the heat pump operates during periods when solar generation is available.
10:30am — Solar generation increases
11:00am — Heat pump starts heating water
12:00pm — Solar generation continues
1:00pm — Hot water tank reaches target temperature
Afternoon/evening — Stored hot water is available for household use
This can increase the amount of your solar electricity that is consumed within the home. Current Solar Victoria requirements also recognise the importance of controllability: eligible heat pumps must have an end-user configurable timer or be connected to solar PV and operate during solar-generation periods.
What About the Midday Power Saver?
Victoria's Midday Power Saver provides eligible households with a free electricity usage period between 11am and 2pm every day. This creates another potential opportunity to operate flexible loads such as heat-pump hot water.
A Melbourne household could potentially coordinate: Solar + Midday Power Saver + Heat Pump + EV + Battery. The aim is to move flexible electricity consumption into the periods where electricity is most beneficial.
Don't Turn Everything On at 11am
If you have a 10 kW solar system, 10 kWh battery, heat-pump hot water, 7 kW EV charger, air conditioning, and dishwasher, and everything starts at 11am, household electrical demand can rise quickly. The Victorian Government recommends staggering high-energy loads during the Midday Power Saver window.
11:00–11:45 — Heat pump
11:45–1:15 — EV charging
1:15–2:00 — Other flexible loads
How Big Should Your Heat Pump Be?
Bigger is not automatically better. The system needs to provide enough hot water for your household without being unnecessarily oversized. Solar Victoria's 2026–27 guidance highlights that a system that is too small can result in regularly running out of hot water, while a system that is too large can cost more to purchase and run.
| Household | Indicative Tank Size |
|---|---|
| 1–2 occupants | 150–225 L |
| 2–4 occupants / around 3 bedrooms | 225–300 L |
| 4+ occupants / 4+ bedrooms | 300 L+ |
These are starting points, not a substitute for proper sizing. A good assessment should consider: number of occupants, number of bathrooms, shower frequency, bath usage, dishwasher, washing machine, existing hot water consumption, solar system size, electricity tariff, available installation location, climate, manufacturer's specifications, and future household changes.
Melbourne Climate & Installation
Heat pumps extract heat from the surrounding air. That means climate and operating temperature matter. Solar Victoria's current 2026–27 requirements state that the minimum operating temperature specified for an eligible heat-pump product should be lower than the minimum recorded temperature for the relevant location, using Bureau of Meteorology data.
Where Should a Heat Pump Be Installed?
The outdoor heat-pump unit needs suitable airflow and clearance. Avoid positioning the unit immediately outside bedrooms, neighbours' sleeping areas, or areas where noise could be disruptive. Installation location also affects maintenance access and system performance.
A heat-pump hot water system is designed to extract heat from the surrounding air even when temperatures are lower. However, efficiency and operating behaviour vary with outdoor temperature, humidity, product design, refrigerant, tank temperature, defrost requirements, and installation.
Refrigerant, Controls, Noise & Safety
Refrigerant
Solar Victoria's 2026–27 requirements state that eligible heat-pump hot water systems must use refrigerants with a Global Warming Potential below 700. When comparing products, don't only ask: "What is the tank capacity?" Also ask: "What refrigerant does it use?"
Smart Controls
Modern heat-pump systems can be scheduled. Solar Victoria's current requirements specify that eligible heat pumps must have a configurable integrated timer or be connected to solar PV so the system can operate during solar-generation periods.
Noise
Heat pumps have an outdoor compressor/fan unit, so some operating noise is normal. For a Melbourne home, placement matters. Ask about operating noise, night mode, installation clearances, minimum operating temperature, defrost behaviour, and manufacturer's recommended location.
Legionella Safety
Hot-water systems need to be managed appropriately for hygiene and safety. Solar Victoria's current product requirements specifically allow heat pumps to operate outside the normal timer window when necessary for adequate hot-water delivery and to support functions such as defrosting and prevention of Legionella growth.
What Happens From 1 March 2027?
This is the part many homeowners are misunderstanding. The Victorian rule does not mean: "Every gas hot water system must be replaced on 1 March 2027."
Instead, existing homes will need to upgrade a gas hot water system to an efficient electric alternative when the gas system reaches end-of-life from 1 March 2027. If your gas hot water system is still working properly, you should understand the rule and plan ahead.
A heat pump is one example of an "efficient electric alternative." For many homes, a heat pump can fit naturally into a broader electrification strategy:
Solar → generates electricity
Heat pump → uses electricity efficiently for hot water
Battery → stores energy where appropriate
EV → uses electricity for transport
Air conditioning → replaces or supplements other heating/cooling systems
What If Your Gas Hot Water Is Already Old?
Don't wait until it completely fails before investigating replacement options. Check: installation date, warranty, current condition, gas usage, available rebates, VEU eligibility, electrical supply, installation location, and future solar plans.
Is a Heat Pump Worth It If You Already Have Solar?
It can be particularly attractive. Your solar system generates electricity during daylight. Your heat pump needs electricity to operate. If the system is scheduled correctly, you may be able to use more of your own solar electricity for hot water rather than exporting as much.
| Feature | Heat Pump Only | Solar + Heat Pump |
|---|---|---|
| Efficient hot water | Yes | Yes |
| Uses electricity | Yes | Yes |
| Can use solar generation | No rooftop solar | Yes |
| Potential self-consumption | N/A | Higher opportunity |
| VEU eligibility | Depends on product/activity | Depends on product/activity |
| Solar Victoria hot water rebate | Potentially | Potentially |
| Solar PV rebate | No | Potentially, separately |
| Suitable for electrification | Yes | Yes |
What If You Don't Have Solar? A heat pump can still make sense without solar. The primary benefit is energy efficiency. You don't need rooftop solar for the heat pump to operate.

How Samsun Energy Would Approach a Heat Pump Installation
A good heat-pump installation starts with the household, not the product brochure.
Assess
Existing hot-water system, household size, hot-water usage, property layout, existing solar, electrical supply, future EV plans, available installation space.
Calculate
Required tank capacity, electricity consumption, potential solar self-consumption, applicable incentives, expected operating costs.
Recommend
Select a suitable system based on capacity, climate, efficiency, controls, refrigerant, warranty, installation location.
Install & Monitor
Complete the plumbing and electrical installation in accordance with applicable requirements. Make sure the system is operating correctly and adjust scheduling around solar generation or electricity tariffs where appropriate.
Real Numbers: What Can You Save?
Solar Victoria says switching from gas to an efficient electric hot water system can save households around $400 per year on energy bills in some circumstances. The Victorian VEU program says heat pumps can use around 60–75% less electricity than conventional electric hot water systems.
These figures are useful benchmarks, but they are not guarantees for your home. Your result depends on: current hot water system, gas price, electricity price, hot water consumption, heat-pump efficiency, household size, operating schedule, climate, and solar generation.
What the Rebates Don't Tell You
A rebate can reduce your upfront cost. It doesn't automatically make every heat pump a good purchase. You still need to consider:
- Product quality — Not every heat pump is equivalent.
- Correct sizing — Too small can mean insufficient hot water. Too large can increase purchase and running costs.
- Installation — A poor installation can undermine a good product.
- Location — Noise, airflow and access matter.
- Controls — A system that can be scheduled gives you more flexibility.
- Warranty — Understand what is covered and who handles warranty claims.
- Future energy use — Your household may add solar, an EV or other electric loads.
The cheapest quote today is not necessarily the lowest-cost solution over the system's useful life.
A Heat Pump Makes More Sense When It Fits the Whole Home
Consider a Melbourne household with 4 people, existing gas hot water, rooftop solar, an EV, air conditioning, and plans for a home battery. Instead of looking at the hot-water system separately, the household could design an integrated energy strategy.
Daytime — Solar generates electricity.
Midday — Heat pump runs during a suitable scheduled period.
EV — Vehicle charges during an appropriate low-cost/free or solar-rich period.
Battery — Stores energy where economically and technically appropriate.
Evening — Battery and grid supply remaining household demand.
This is the direction modern household energy management is heading.
Is 2026 the Right Time to Replace Your Gas Hot Water?
If your existing system is healthy and relatively new, there may be no reason to rush purely because of the 2027 rule. If it is approaching end-of-life, however, waiting until it fails completely may be inconvenient.
Planning ahead gives you time to:
- Compare heat-pump models
- Check rebates and VEU eligibility
- Plan the installation location
- Assess electrical requirements
- Coordinate with solar
- Compare quotes
It also gives you time to make the decision based on numbers rather than emergency replacement.
Frequently Asked Questions
How much is the Victorian heat pump hot water rebate in 2026?
Eligible households can receive up to $1,000 for eligible hot water products, or up to $1,400 for products that qualify under the locally made incentive. Eligibility conditions apply.
Can I get both the Solar Victoria rebate and VEU discount?
Eligible households may be able to receive both when the product, activity, provider and household meet the relevant requirements. Solar Victoria specifically confirms that the programs can be combined in eligible circumstances.
Do I need to replace my gas hot water system before 1 March 2027?
Not necessarily. From 1 March 2027, existing homes must upgrade gas hot water systems to efficient electric alternatives when the gas system reaches end-of-life.
Can a heat pump run from solar panels?
Yes. Heat-pump systems can be scheduled to operate during solar-generation periods, and current Solar Victoria requirements specifically provide for timer-based or solar-linked operation.
Can I use the Midday Power Saver to run my heat pump?
Potentially, if your household is eligible for the Midday Power Saver and the system is scheduled appropriately. The 11am–2pm window can be useful for flexible loads such as hot water.
How big should my heat-pump hot-water tank be?
It depends on household size and usage. Indicative guidance ranges from around 150–225 L for 1–2 occupants to more than 300 L for larger households, but the final size should be selected based on actual demand and the manufacturer's specifications.
Are all heat pumps eligible for Victorian rebates?
No. Eligible products must meet the relevant program requirements and be listed on the applicable Solar Victoria product list.
Can a heat pump replace gas hot water?
Yes. Heat pumps are one of the efficient electric alternatives identified by the Victorian Government for replacing gas hot water systems.
Final Takeaway
For Victorian homeowners, 2026 is a particularly important year to review hot water. The combination of Solar Victoria rebates, VEU discounts, STCs where applicable, lower electricity consumption, solar integration, and the 1 March 2027 gas hot water changes makes heat-pump hot water worth investigating for many homes.
But don't buy a heat pump simply because there is a rebate. Start with the home.
Then choose the system. For a Melbourne homeowner, the best heat-pump installation is not necessarily the biggest tank or the cheapest quote. It is the system that provides enough hot water, works properly in Melbourne's climate, fits the property, can be operated efficiently, and makes sense alongside the rest of the home's energy system.
Ready to Upgrade Your Hot Water?
If your gas or electric hot water system is approaching the end of its life, Samsun Energy can assess the property, household requirements, available incentives and the best way to integrate heat-pump hot water with solar and other energy systems.
Don't wait for the old hot water system to fail before you start planning the replacement.
