Hot Water System Installation & Replacement
When a system has reached the end, replacing it properly matters more than replacing it fast. Supply and installation of electric, solar, gas and heat pump hot water systems.
Replacing like for like isn’t automatic
The default when a hot water system dies is to put the same thing back. Often that’s exactly right — the connections are there, the space suits it, and the household is happy with how it performed.
But it’s worth at least asking the question. Households change. A system that was right for two people may not be right for five. If your electric system has been running out every evening for years, replacing it with an identical unit repeats the problem. If a heat pump would suit your place and your usage, that’s worth knowing before you commit, not after.
We’ll tell you what fits your situation, including when the answer is “the same again, that was fine”.
What goes into a proper installation
A hot water installation is more than lifting the old one out. It covers the water connections, the relief and tempering valves, the drain line, the base or mounting, and — depending on the system type — the electrical connection or gas connection. Solar adds the collectors and circulation. Heat pumps add ventilation and placement considerations.
All of it’s licensed work. Advance Hotwater holds QBCC licence 1204307, plumbing licence PD23831 and gas licence L25976.
Removing the old system
The old unit has to come out and be disposed of properly, and the new one has to sit correctly with the right clearances and drainage. Unglamorous detail — and the part that determines whether the new system gives you trouble in three years.

What usually goes wrong
These are the symptoms we hear about most often. A good starting point for the call.
- Tank has corroded and is leaking
- System is old and repairs no longer stack up
- Parts no longer available for the model
- System never kept up with the household
- Renovating or relocating the unit
- Changing from one system type to another
- Bought a home with a failing system
- Wanting the job done before the old one dies
Please don’t troubleshoot it yourself. Hot water systems combine electricity, gas, stored pressure and water hot enough to scald. If something looks, smells or sounds wrong, turn it off if it’s safe to do so and call (07) 3801 2155.
What actually drives the decision
There’s no single best hot water system. There’s a system that suits your household, your property and the services already connected to it.
Household size
How many people, and how much hot water gets used at once. The biggest single factor in getting the sizing right.
What’s already there
Existing electrical supply, gas connection, roof access and the space the unit sits in all shape what is practical.
Where it can go
Heat pumps need airflow. Solar needs suitable roof orientation. Gas needs ventilation and clearances. Placement isn’t an afterthought.
Running cost
Different system types cost different amounts to run. We’ll explain the differences for the options that suit your place.
