Free Heat Pump Hot Water System: What “Free” Really Means Before You Upgrade

Oct 3, 2024

Searching for a free heat pump hot water system usually means one thing: you want to replace an old electric or gas hot water unit without paying full price upfront. In some states, rebates, discounts, STCs and energy-saving incentives can reduce the cost of a heat pump hot water system, but “free” is not guaranteed for every home, every product or every installer.

The final price depends on your state, household eligibility, existing hot water system, selected product, approved supplier requirements, installation conditions and current rebate rules. Some offers may advertise very low upfront prices, but you still need to check what is included, what is excluded and whether the system is actually suitable for your home.

Installed Today makes it easy to compare and order heat pump hot water systems online, with supply-only ordering available across major Australian metro areas and selected supplied-and-installed options available on eligible products in Brisbane and Gold Coast service areas.

Quick Answer: Can You Really Get a Free Heat Pump Hot Water System?

Sometimes a heat pump hot water system may be advertised as “free” or heavily discounted after rebates, but homeowners should treat this carefully.

In most cases:

Rebates and discounts reduce the upfront cost
The final price depends on eligibility and provider requirements
Installation extras may still apply
Not every heat pump model qualifies
Not every property qualifies
Not every supplier can process every rebate
Supply-only purchases may not qualify for some incentive pathways
Rebate amounts and rules can change

Before ordering, confirm the current rebate rules, approved supplier requirements and installation inclusions. A low advertised price is only good value if the system suits the home and the total installed cost is clear.

What Is a Heat Pump Hot Water System?

A heat pump hot water system is an electric hot water system that uses heat from the surrounding air to help heat stored water. It works differently from a standard electric storage hot water system, which relies mainly on an electric element.

A heat pump can reduce energy use for water heating when installed in the right location. It needs outdoor air movement, drainage, electrical suitability and a sensible noise location.

A heat pump may suit homes that:

Want to reduce hot water electricity use
Are replacing an older electric storage system
Have suitable outdoor space
Have good airflow around the unit
Can manage condensate drainage
Have suitable electrical supply
Want to pair hot water heating with rooftop solar where timing and usage suit
Are planning a longer-term energy efficiency upgrade

A heat pump is not automatically the best choice for every property. Site suitability matters.

Why “Free Heat Pump Hot Water” Claims Need Care

The word “free” can be misleading if it only refers to the product after rebates, while other costs are not included.

A free or heavily discounted offer may not include:

Installation extras
Electrical work
Plumbing alterations
Valve upgrades
Drainage changes
Condensate drainage
Old unit removal
Disposal
Compliance upgrades
Switchboard work
Concrete base or slab work
Longer pipe runs
Relocation of the unit
Rebate administration requirements

For supply-only orders, the product price generally does not include installation, valves, electrical work, gas work, pipework changes, drainage, old unit removal, disposal or compliance upgrades unless those options are clearly selected or shown.

Heat Pump Rebates and Discounts: What to Check

Heat pump hot water incentives can vary by state and program. Some incentives may be applied as an upfront discount through an approved supplier. Others may involve rebates, STCs or paperwork handled through specific channels.

Before relying on a rebate or “free” claim, check:

Which state or territory the offer applies to
Whether your property qualifies
Whether your household income affects eligibility
Whether your existing hot water system qualifies
Whether the new heat pump model qualifies
Whether the supplier must be approved
Whether your installer must meet program requirements
Whether the rebate is applied upfront or claimed later
Whether supply-only ordering affects eligibility
Whether any customer co-payment applies
Whether the offer includes installation or product only

Rebates, STCs and incentives can change. Always confirm current eligibility before ordering or budgeting around a discount.

Victoria Heat Pump Hot Water Rebates

Victoria is one of the most common states where homeowners search for free or discounted heat pump hot water systems. Victorian programs may offer hot water rebates, discounts or incentives for eligible heat pump or solar hot water upgrades.

However, this does not mean every Victorian household gets a free system.

Eligibility may depend on:

Household income
Property location
Whether the property has already received a rebate
Existing hot water system type
Product eligibility
Supplier participation
Installer requirements
Whether the system is a replacement
Current program rules
Documentation and approval before installation

If you are in Victoria, check eligibility before ordering a supply-only product. Some rebate pathways may require an approved provider or authorised retailer to manage the process.

NSW Heat Pump Hot Water Rebates

NSW also has energy-saving upgrade incentives that may reduce the cost of eligible heat pump hot water systems. These are often linked to approved providers and energy savings certificate programs.

For NSW homes, check whether:

Your existing system qualifies
The selected heat pump is approved
The provider is accredited
The installation must be arranged through a specific supplier
A minimum customer contribution applies
Supply-only purchasing affects eligibility
The discount is applied before or after installation

Do not assume a rebate applies just because a heat pump is energy efficient. The product, property, installer and paperwork all matter.

Queensland, Brisbane and Gold Coast Considerations

For Brisbane and Gold Coast homes, heat pump hot water selection is often driven by outdoor location, airflow, drainage, electrical suitability and household demand.

Installed Today offers selected supplied-and-installed options on eligible products in Brisbane and Gold Coast service areas. Supply-only ordering is available across major Australian metro areas.

For Queensland customers, check current rebate and STC rules before ordering. Incentive availability can change, and eligibility may depend on product type, location and current government or certificate program settings.

Supply-Only Orders and Rebates

This is one of the most important points for Installed Today customers.

Supply-only ordering can be a good option when you already have a licensed installer organised and want to buy the product online. However, some rebates or discounts may need to be arranged through an approved supplier before the system is installed.

Before ordering a supply-only heat pump, ask:

Does the rebate apply to supply-only purchases?
Does the supplier need to be approved?
Does the installer need to complete rebate paperwork?
Does the product need to be selected from an approved list?
Does the old system need to be removed in a certain way?
Does the rebate require pre-approval before installation?
Will ordering first make the system ineligible?
Are STCs included, excluded or handled separately?

If rebate eligibility is important to your budget, confirm these details before buying.

Choosing the Right Heat Pump Hot Water System

A discounted heat pump is only a good deal if it suits your household. Choosing the wrong size or installing it in the wrong location can lead to poor performance, noise issues or hot water shortages.

When comparing heat pump hot water systems, consider:

Number of people in the home
Number of bathrooms
Shower habits
Morning and evening peak demand
Whether the old system ran out of hot water
Available outdoor space
Airflow around the unit
Condensate drainage
Noise placement
Electrical requirements
Access for delivery and installation
Warranty and support
Cartridge, anode or servicing requirements where relevant
Whether the system can pair with rooftop solar timing

For many homes, products in the medium heat pump hot water systems 200L–280L range are commonly compared. Larger households may need to review large heat pump hot water systems.

Integrated vs Split Heat Pump Hot Water Systems

Heat pump hot water systems are commonly available as integrated or split-style systems.

Integrated Heat Pump Systems

An integrated heat pump combines the tank and heat pump components into one unit. This is common for residential heat pump hot water systems and can be simpler to place where there is suitable outdoor space.

Integrated systems may suit:

Standard residential replacements
Homes with outdoor space near the old hot water location
Customers wanting a neat all-in-one system
Properties with suitable access and airflow

Split Heat Pump Systems

A split system separates the tank and heat pump components. This may allow more flexible placement in some applications, but it can also involve more installation planning.

Split systems may suit:

Homes with specific space constraints
Properties needing more flexible component positioning
Situations where noise placement needs extra thought
Some larger or more complex installations

Your licensed installer should confirm which format suits the property.

Heat Pump Size Guide

The right heat pump size depends on household hot water demand, not just rebate eligibility.

A system that is too small may run out of hot water. A system that is too large may cost more than needed and may not suit the location.

Sizing depends on:

Number of people in the home
Number of bathrooms
Shower duration
Bath use
Kitchen and laundry use
Whether multiple showers run at once
Peak hot water times
Recovery rate
Climate and installation location
Existing system size
Whether the old system was running out of hot water

Popular heat pump options include:

Heat Pump vs Electric Hot Water

A heat pump is often compared with a standard electric hot water system.

Electric storage systems are usually simpler and can cost less upfront. Heat pumps often cost more upfront but may reduce running costs in the right location.

Option	Best For	Key Considerations
Electric storage	Simple replacement, homes without gas, lower upfront product price	Running costs may be higher depending on tariff and usage
Heat pump	Efficiency-focused homes with suitable outdoor space	Needs airflow, drainage, electrical suitability and noise planning

If your old electric storage system was already running out of hot water, do not replace it with the same size without checking your household demand.

Common electric replacement categories include 250L electric hot water systems, 315L electric hot water systems and 400L electric hot water systems.

Heat Pump vs Gas Hot Water

Heat pumps are also commonly compared with gas hot water systems, especially when replacing an old gas storage or instant gas unit.

Gas may suit homes that already have natural gas or LPG. Heat pumps may suit homes looking to reduce gas use or move toward an electric home.

Gas options include:

Gas work must be completed by a licensed gas fitter. Natural gas and LPG units are not interchangeable. For larger instant gas systems, gas pipe sizing and water pressure must support the unit.

Can Heat Pump Hot Water Work With Solar Panels?

Yes, a heat pump can pair well with rooftop solar where the timer settings, household usage and electrical setup suit.

The idea is to run the heat pump during the day when solar production is stronger. This may help use more of your own solar energy, depending on your system and usage pattern.

However, it should not be described as “free hot water from solar”. There are still product, installation, maintenance and energy considerations. A solar-friendly setup depends on the actual home.

Installation Requirements for Heat Pump Hot Water

A heat pump needs the right location to work properly.

Before ordering, check:

Outdoor location
Clear airflow
Manufacturer clearance requirements
Condensate drainage
Electrical supply
Base or slab condition
Access for delivery
Future servicing access
Distance from bedrooms
Distance from neighbours
Noise placement
Pipework route
Overflow and drain points
Existing valves and compliance

A heat pump should not be boxed into a tight space with poor airflow. Poor placement can affect performance and comfort.

What Costs Might Still Apply With a “Free” Heat Pump Offer?

Even when a rebate reduces the product cost, additional site costs may still apply.

Possible costs include:

Plumbing labour
Electrical upgrades
New isolator or wiring
Switchboard work
Tempering valve
Pressure limiting valve
Expansion control valve
Drainage alterations
Condensate drain
Pipework changes
Concrete base
Old unit removal
Disposal
Extra access requirements
Relocation of the system
Compliance upgrades

Always ask for a full written breakdown before accepting a “free” or heavily discounted offer.

Avoiding Poor Rebate Deals

A rebate should make a good system more affordable. It should not be the only reason you choose a product.

Avoid these mistakes:

Choosing Only Because It Is Free

A low upfront price is not enough. The system must suit your household size, location and long-term use.

Ignoring Brand and Support

Check the brand, warranty, spare parts access and after-sales support. A cheap system can become expensive if support is poor.

Not Checking Noise Placement

Heat pumps have fans and compressors. They need sensible placement away from bedrooms, neighbouring windows and tight acoustic spaces.

Not Checking Hot Water Capacity

A smaller discounted unit may not suit a family home with high shower demand.

Assuming Rebates Cover Everything

Rebates may not cover site extras, compliance upgrades or installation complexities.

Ordering Before Confirming Eligibility

Some rebate pathways require pre-approval or an approved supplier. Ordering first can create problems.

Frequently Asked Questions

Can I get a free heat pump hot water system?

Possibly, but it depends on your state, eligibility, product, provider and installation conditions. Many offers are rebates or discounts rather than guaranteed free systems for every household.

Are heat pump hot water rebates still available?

Heat pump rebates and discounts may be available in some states and territories, but rules can change. Check the current program before ordering or accepting a quote.

Does a heat pump rebate apply to supply-only orders?

Not always. Some rebate programs require an approved supplier or installer to manage the process before installation. Confirm this before buying a supply-only product.

Is a heat pump hot water system cheaper to run?

A heat pump can use less electricity than standard electric storage in the right location. Actual running costs depend on household usage, tariff, climate, settings and installation conditions.

Is a heat pump better than electric hot water?

A heat pump can be more efficient, but it needs suitable airflow, drainage, outdoor space, electrical supply and noise placement. Standard electric storage may still suit some homes wanting a simple replacement.

Is a heat pump better than gas hot water?

It depends on the property. Heat pumps may suit homes moving away from gas or wanting to use more solar electricity. Gas systems may still suit homes with suitable natural gas or LPG infrastructure.

What size heat pump hot water system do I need?

The right size depends on people in the home, bathrooms, shower habits and peak usage. Many homes compare 250L to 280L heat pumps, while larger households may need 280L-plus options.

Can I install a heat pump hot water system myself?

No. Heat pump hot water systems involve plumbing, electrical work, valves, drainage and compliance requirements. Use licensed trades.

What is not included in supply-only heat pump pricing?

Supply-only pricing generally excludes installation, valves, electrical work, pipework changes, drainage, old unit removal, disposal and compliance upgrades unless selected or clearly shown.

Final Word

A free heat pump hot water system sounds appealing, but the safest way to approach the offer is to check the full picture. Rebates, STCs and discounts can reduce the upfront cost, but they do not automatically make every system free or suitable.

The right heat pump should match your household size, hot water demand, outdoor location, airflow, drainage, electrical setup and rebate pathway. If you are ordering supply only through Installed Today, confirm rebate eligibility and site suitability before buying.

A good rebate can make a quality heat pump better value. It should never replace proper product selection, installer advice and a clear understanding of the total cost.
