Planning to install a gas heater and trying to work out the likely cost? The price of gas heater installation in Melbourne can vary considerably depending on the type of heater, where it’s being installed and how much gas work is required.
A straightforward gas heater replacement may involve relatively little work, while installing a gas heater where there isn’t an existing gas connection can require additional pipework.
Understanding what goes into the price can make it easier to compare quotes and budget for the project.
As a rough guide, gas heater installation in Melbourne can cost around $800 to $4,000+, although the actual price depends on the type of heater and the work required at the property.
| Installation type | Rough Melbourne cost |
| Basic gas heater installation | $800–$1,500+ |
| Gas wall furnace / space heater | $1,500–$4,000 |
| More complex installation with new gas pipework | $2,000–$4,000+ |
| Ducted gas heating system | $4,000–$8,000+ |
So, there isn’t one fixed price for installing a gas heater.
For this reason, a plumber or gasfitter will generally need to assess the property before providing an accurate quote.
If you’re comparing prices, make sure you will get confirmation that a quote covers the appliance, labour, gas connections and any additional work required.
The biggest difference between two installation quotes often comes down to the amount of work involved rather than the heater alone.
Replacing an existing gas heater in the same location can be relatively straightforward when the existing gas line supply and connections are suitable for the new appliance.
A new installation may require gas pipework to be extended or modified. The amount of work depends on where the heater will be located and how far it is from the available gas supply.
A wall-mounted heater, freestanding appliance and ducted gas heating system can involve very different levels of labour and preparation. The size and gas requirements of the appliance can also affect the work required.
This is why comparing the installation cost of two different heater types isn’t always useful. The installation process itself may be quite different.
A replacement usually has an advantage because some of the required infrastructure may already be in place.
However, an existing installation still needs to be assessed before the new heater is connected. The pipework, connections, flue and other components need to be suitable for the replacement appliance.
An older gas heater may also have outdated or damaged components that need to be addressed before the new unit can be installed.
A heater needs an adequate gas supply to operate correctly. When the existing pipe is too small, damaged or unsuitable for the new appliance, it may need to be modified or replaced.
The distance between the gas supply and the heater can also affect the amount of pipework and labour required.
An easily accessible outdoor or wall-mounted location may be simpler to work on than an area where the installer needs to work around walls, flooring, cabinetry or other structures.
For retrofit installations, accessing the required pipe route can sometimes be one of the more involved parts of the job.
You don’t necessarily need to choose the cheapest heater or installer to keep the project within budget. A better approach is to get a proper assessment before installation. This can help prevent unexpected work from appearing halfway through the job.
A few practical steps can help such as:
The cost varies depending on the heater type, existing gas connections, pipework, accessibility and whether the job involves a replacement or completely new installation. A property assessment is the best way to obtain an accurate quote.
It can be, particularly when the existing gas connection and installation are suitable for the replacement heater. However, the existing system still needs to be checked before the new appliance is connected.
Not always. Some quotes cover installation labour only, while others may include the appliance and additional materials. Always check exactly what is included before comparing quotes.
The suitable location depends on the type of heater, the property’s layout and the installation requirements of the appliance. A qualified gasfitter can assess the proposed location before installation.
Gas appliances need to be installed and connected by an appropriately licensed professional. Incorrect installation can create serious risks, including gas leaks, fire and carbon monoxide exposure.
The best way to understand your actual installation cost is to have the property and existing gas system assessed. This allows the installer to account for the heater type, gas supply, pipework, accessibility and any additional work required.
