Your hot water system is on its way out, or has already failed, and you want a sense of the cost before you start ringing around. Prices vary a lot between system types, so it helps to know the market ranges first.
Brigs Plumbing is a Thorneside plumber (QBCC licence 15161521) that does hot water work for homes across Brisbane and the Redlands, and you can read about our hot water services in Brisbane on the main service page. This guide covers the published market ranges, what moves the price, and why a quote is the only reliable answer for your home.

The real cost depends on the job, and a quote is the way to know.
Hot water system costs in Brisbane by system type
The table below shows the Brisbane supply-and-install ranges published by What's The Damage (October 2026). They are market figures from an independent source, not Brigs Plumbing prices.
| System type | What's The Damage Brisbane range |
|---|---|
| Electric storage | $800 to $3,000 |
| Gas storage | $1,200 to $3,500 |
| Continuous flow gas | $1,500 to $3,500 |
| Heat pump | $3,000 to $6,000 before rebates |
| Solar hot water | $3,500 to $7,000 |
What's The Damage also notes that Brisbane's warm climate suits heat pump hot water. For heat pumps, ask your installer which government incentives apply to your system.

We look at the job and quote before any work starts, so you know the cost up front.
What changes the cost of a new hot water system?
The same guide lists these factors as the ones that move the price:
- System type and size. The ranges above show how far apart the system types sit, and size within a type adds to that.
- Access. Where the unit sits and how easy it is to reach affects the job.
- Whether the location or fuel type changes. Keeping the same spot and the same energy source is a different job from moving the unit or switching fuel.
- Removal of the old unit. Removal and disposal can be a separate line item.
If your hot water system has failed or is leaking right now, see our emergency plumber for a failed or leaking hot water system in Brisbane. If the problem looks like a valve or pipework fault rather than the heater itself, our general plumbing in Brisbane page may be the better fit.
