If your hot water system is on its way out, a heat pump is one of the replacement options worth pricing up. This guide sets out published market ranges for Brisbane homes, and if you want to talk through a replacement, see our hot water service in Brisbane.
How much does a heat pump hot water system cost in Brisbane?
What's The Damage, an independent cost guide, puts a heat pump hot water system in Brisbane at $3,000 to $6,000 before rebates (typically $4,200) and $2,500 to $5,300 after rebates (typically $3,600), supply and install (October 2026). These are market ranges, not Brigs Plumbing prices.
What's The Damage also notes Brisbane's warm climate suits heat pump hot water.
The ranges are wide because no two installs are the same. The real cost depends on the job, and the only way to know what yours will cost is a quote.

What affects the cost of a heat pump install?
What's The Damage lists the things that change the price of a hot water system in Brisbane. For a heat pump, they are:
- System type and size: the model you choose and the size of system your household needs.
- Access: how easily the old unit can be reached and the new one installed and connected.
- Whether the location or fuel type changes: moving the system to a different spot, or changing from one fuel type to another, can change the scope of the work.
- Removal of the old unit: taking out and disposing of the existing system.
Because each of these varies from house to house, two homes can land at very different points inside the same published range. That is why a range from a cost guide is a starting point for budgeting and not a final figure.
What does removing the old system cost?
What's The Damage, an independent cost guide, puts old system removal and disposal at $75 to $200 in Brisbane (October 2026). Ask whether removal is included in any quote you receive, so you can compare quotes on the same basis.
Which government incentives apply to a heat pump?
Incentives vary by system and by your circumstances, and the after-rebate range is the guide's estimate. Ask your installer which government incentives apply to your system, and have that shown in the quote.
Want a firm price for your job?
We look at the job and quote before any work starts, so you know the cost up front.
How do you get a firm price for your home?
Published ranges tell you roughly where the market sits. They cannot account for the system type and size, your access, whether the location or fuel type changes, or removal of the old unit. A plumber needs to see the job to price it properly, and Brigs Plumbing quotes every job before work starts.
When you ask for quotes, it helps to have a few details ready:
- The type of system you have now, and where it is installed.
- The type of system you are considering.
- Whether you plan to keep the system in the same location.
- Whether you want the old unit removed and disposed of.
- Any questions about government incentives that might apply.
With those details, an installer can quote on the actual job instead of a market average.
