Hot Water System FAQs: Everything You Need to know About VEU Upgrades

Hot Water System FAQs: Everything You Need to know About VEU Upgrades

If you’ve been copping high electricity bills and your old hot water system is on its last legs, you’ve probably heard about the Victorian Energy Upgrades (VEU) program. But with so much information floating around online, it can be hard to know what’s actually true, what you’re actually entitled to, and where to even start.

This guide pulls together the most common questions Melbourne homeowners are asking about VEU hot water upgrades and gives you straight answers, no fluff.

What Is the Victorian Energy Upgrades (VEU) Program?

The VEU program is a Victorian Government initiative designed to help households and businesses reduce their energy use and carbon emissions. Under the program, accredited providers can offer heavily discounted upgrades on energy-efficient products, including hot water systems by claiming Victorian Energy Efficiency Certificates (VEECs) on your behalf.

In plain terms: the government subsidises part of the cost of your upgrade, and an accredited installer passes that saving directly on to you at the point of installation. It’s not a cash rebate you apply for after the fact the discount comes off the price upfront.

The program is pushing Victorians away from old, inefficient electric storage and gas systems toward modern heat pump hot water systems, which use significantly less energy to do the same job.

Who Is Eligible for a VEU Hot Water Upgrade?

This is one of the most common questions, and the good news is that eligibility is quite broad.

Homeowners can access VEU discounts when replacing an existing hot water system with an eligible model. You don’t need to be on a low income or hold a concession card; the program is open to most Victorian residential properties.

Landlords and rental property owners are also eligible, and many are taking advantage of the scheme to upgrade older systems in their rental properties. Not only does this reduce ongoing running costs (which can benefit tenants), it also adds long-term value to the property.

Apartment owners can participate, though there are some additional considerations around space requirements and strata approval that may apply depending on your building.

Pensioners and concession card holders may be eligible for additional savings through complementary state and federal programs, so it’s worth checking what you might qualify for beyond the standard VEU discount.

Businesses can also participate in the VEU program, though the eligibility rules differ slightly from residential upgrades.

What Hot Water Systems Can Be Upgraded Under VEU?

Not every system qualifies, so it’s important to understand what’s included.

Heat pump hot water systems are the standout option under the VEU program. These systems work like a reverse refrigerator; they extract heat from the surrounding air and use it to heat water, rather than generating heat directly. This makes them up to three times more energy-efficient than a standard electric storage system.

Electric storage system replacements are eligible in certain circumstances, particularly when upgrading from older, less efficient models to high-efficiency alternatives.

Gas hot water systems are generally not incentivised under the program, with the government actively steering households away from gas and toward electric-based solutions.

Solar-compatible systems that work alongside existing rooftop solar setups can also qualify, making it an even smarter upgrade if you’ve already invested in solar panels.

Systems that are not eligible typically include DIY installations, systems installed by non-accredited providers, and certain older or non-approved models. Always confirm eligibility with your installer before booking.

How Much Does a VEU Hot Water Upgrade Cost?

Costs vary depending on the system you choose and your property’s specific requirements, but here’s a realistic picture for Melbourne homeowners.

Before any discounts, a quality heat pump hot water system (including installation) might typically run anywhere from $3,000 to $5,000 or more. The VEU discount can significantly reduce this upfront cost, with savings varying based on the system type and size.

Example Cost Comparison:

System Type	Estimated Annual Running Cost
Old 250L electric storage	~$700–$900/year
Heat pump (250–270L)	~$200–$350/year
Potential annual saving	~$400–$600/year

These figures are estimates and will vary based on your electricity tariff, household usage, and system model, but they give you a sense of the ongoing savings on offer.

Factors that affect your total upgrade cost include the size of the system you need, your existing plumbing and electrical setup, the location of installation (indoor vs outdoor), and whether any additional work is required to bring your home up to current standards.

How Much Can I Save by Upgrading My Hot Water System?

Over the long term, the savings are genuinely significant. Heat pump hot water systems are typically around 60–75% cheaper to run than conventional electric storage systems.

For the average Melbourne household, that could mean saving $400 to $600 per year on hot water energy costs alone. Over a 10-year period, that’s potentially $4,000 to $6,000 back in your pocket, well beyond the upfront cost of the upgrade, especially after the VEU discount is applied.

Beyond the dollars, upgrading also reduces your household’s carbon footprint. Heat pumps produce significantly fewer greenhouse gas emissions than older electric or gas systems, particularly when paired with renewable electricity.

Why Are Heat Pump Hot Water Systems So Popular?

Heat pumps have become the go-to upgrade for good reason. Here’s what’s driving the shift:

How the technology works: 

Rather than heating water from scratch with an electric element or gas flame, a heat pump draws warmth from the ambient air, even on cooler days, and transfers it to the water in the tank. This process is far more energy-efficient than traditional heating methods.

Performance in Melbourne’s climate: 

Melbourne’s mild-to-cool climate is actually well-suited to heat pump technology. Modern units are designed to operate effectively even in temperatures well below zero, so winter performance isn’t the concern it once was.

Energy efficiency advantages: 

Most high-quality heat pumps have a Coefficient of Performance (COP) of around 3–4, meaning they produce 3-4 units of heat for every 1 unit of electricity consumed. That’s a dramatic improvement over a standard electric element.

Common myths busted: 

Some homeowners worry that heat pumps are noisy, don’t work in winter, or require too much space. In reality, modern units are relatively quiet, cold-weather rated, and available in compact configurations suited to a range of Melbourne homes.

How Long Does the Installation Process Take?

For most Melbourne households, a straightforward hot water system replacement can be completed in a single day, often in just a few hours.

The process typically involves a site assessment (which may be done on the same day or as a separate visit), removal of your old system, installation of the new heat pump unit, plumbing and electrical connections, system testing, and compliance documentation.

In most cases, your hot water supply will be interrupted only briefly during the switchover. Many providers offer same-day replacement, so you won’t be without hot water overnight.

What Size Hot Water System Do I Need?

Getting the right size is important. Too small and you’ll run out of hot water; too large and you’ll pay more than necessary to run it.

As a general guide:

A 125–160L system typically suits 1–2 people. A 250–270L system is appropriate for a household of 3–4 people. A 315–400L system is better suited to larger families of 5 or more.

Factors like the number of bathrooms, whether you have a bathtub, and your household’s hot water habits will all influence the right size for your home. Your installer should assess your usage before recommending a specific model.

What Warranties Come with VEU-Approved Hot Water Systems?

Most heat pump hot water systems installed under the VEU program come with manufacturer warranties of 5 to 10 years on the tank and 2 to 5 years on the compressor and other components. Installation workmanship is typically covered by a separate guarantee from the installer.

To keep your warranty valid, you’ll generally need to ensure the system is serviced according to the manufacturer’s schedule and that any issues are reported and addressed promptly.

Common Problems Homeowners Experience Before Upgrading

If any of these sound familiar, it’s probably time to consider an upgrade:

You’re regularly running out of hot water during peak household usage times. Your electricity bills seem higher than they should be. Your current storage tank is leaking or showing signs of rust. Water temperatures are inconsistent, too hot, too cold, or fluctuating. You’re calling a plumber for repairs more and more frequently.

These are all signs that your existing system is ageing out and costing you more than a new, efficient system would.

How to Choose the Right VEU Hot Water Installer in Melbourne

Not all installers are equal. When choosing a provider, look for the following:

• Ensure they are accredited under the VEU program; only accredited providers can legally offer VEU discounts. 
• Check that they hold the appropriate plumbing and electrical licences for Victoria. 
• Ask for references or reviews from previous Melbourne customers. 
• Get a written quote that clearly shows the VEU discount applied and what’s included in the installation.

Red flags to watch out for include pressure to make a same-day decision, vague or verbal-only quotes, and providers who can’t clearly explain how the VEU discount is calculated.
