How much does it cost to install a wood heater in Australia?
Posted by Ultimate Showroom on
A typical wood heater installation costs between $1,000 and $5,500 for labour and materials, on top of the price of the heater itself. Freestanding models sit at the lower end. Inbuilt installations that need structural work push toward the higher end. The exact cost depends on your home, your roof, and the type of heater you choose.
That range is wide, and there are good reasons for it. A straightforward freestanding install in a single-storey home with easy roof access might come in under $1,500. An inbuilt wood heater fitted into a new cavity in a two-storey home with a cathedral ceiling could run past $4,000 before you factor in plastering and finishing. The difference comes down to how much work your home needs beyond just placing the heater and running a flue.
Here’s what drives the cost – and how to make sure you’re not caught off guard.
What is included in a wood heater installation?
When an installer quotes on a wood heater, the price usually covers positioning the heater, installing the flue through the ceiling and roof, fitting a flue cowl on top, and checking that all clearances to walls, floors, and combustible materials meet the requirements of Australian Standard AS/NZS 2918. That standard governs every wood heater installation in Australia and sets minimum distances, flue heights, and hearth specifications.
The quote should also include a non-combustible hearth – either confirming your existing floor surface is suitable or laying a new one. After installation, a properly run job finishes with a first light-up to check the draw and operation, followed by a compliance certificate.
That certificate matters. You’ll need it for your home insurance, and you’ll need it again if you ever sell the property. If an installer doesn’t mention it, ask.
What affects the cost of installing a wood heater?
Not every home is the same, and installation costs reflect that. These are the main variables:
Freestanding vs inbuilt. A freestanding wood heater is the simpler job – it sits on a hearth pad, the flue runs straight up through the ceiling, and the installer fits heat shields where needed. An inbuilt heater needs a cavity built into the wall, which may require framing, fireproofing, and finishing work by additional trades. That extra labour is where inbuilt installations start climbing past the $3,000 mark.
Single-storey vs multi-storey. The flue must run from the heater to at least 4.6 metres above the hearth – that’s the minimum under AS/NZS 2918. In a single-storey home, a standard flue kit usually covers it. In a two-storey home, you’ll need more flue pipe and potentially scaffolding for roof access.
Existing chimney vs new penetration. If your home already has a masonry chimney from an old open fireplace, an insert heater may fit with relatively little work. If you’re starting from scratch, the flue penetration through the ceiling and roof is the biggest part of the job – and the biggest variable in the quote.
Hearth requirements. Every wood heater needs a non-combustible base underneath it. Concrete slabs and existing tiled floors often qualify. If your floor is timber, carpet, or another combustible material, a new hearth pad needs to be built.
Structural modifications. Inbuilt installations sometimes require wall reinforcement or the construction of a fire-rated cavity. This is where costs can step up significantly, especially in older homes where the wall framing wasn’t designed with a heater in mind.
Roof access and ceiling type. Tight roof cavities, raked ceilings, and difficult roof pitches all add time. If your installer needs to work around obstacles or bring in specialised equipment, expect the quote to reflect that.
What is not included in a wood heater installation quote?
It’s worth knowing what sits outside the installation price:
- The heater itself – installation covers the labour and materials to fit it into your home, not the unit.
- Decorative mantels, fascias, and surrounds.
- Plastering or painting around an inbuilt installation (typically a separate trade).
- Council permits, where required. In Victoria, you generally don’t need a building permit, but the work must be done by a licensed plumber. In NSW, you may need to submit a planning application through the NSW Planning Portal before installation begins. Check with your local council – requirements differ by state and sometimes by municipality.
- Electrical work for fan-forced models that need a nearby power point.
- Firewood storage.
How can you avoid unexpected costs during installation?
The single best thing you can do is book a site assessment before you commit. A good installer will visit your home, inspect the roof space, measure the flue run, and identify anything that might complicate the job – before they put a number on paper.
Beyond that:
Get an itemised quote. You should be able to see labour, flue materials, hearth work, and any structural modifications listed separately. If the quote is a single lump figure with no breakdown, ask for one.
Ask about flue length. This is the most common source of quote variation between homes. Higher ceilings or steeper rooflines mean a longer flue run and a higher cost. It’s not something to be surprised by – it’s something to ask about upfront.
Demand a compliance certificate. Once the job is done, your installer should provide a certificate confirming the installation meets AS/NZS 2918 and the manufacturer’s instructions.
Notify your home insurance company. They need to know a wood heater has been installed. Skipping this step can create serious problems down the track.
Don’t choose purely on price. A poorly installed wood heater is a fire risk, and if the installation doesn’t comply with the Australian Standard, your insurance may not cover you. Ask to see a compliance certificate from a previous job. If they can’t produce one, move on.
Is a wood heater worth the investment?
A quality wood heater with a proper installation is a long-term asset. Most well-built units last 15 to 20 years or more with regular maintenance. Ultimate Fires backs every model with a 10-year firebox warranty – a reflection of how long these heaters are designed to perform.
Running costs are where wood heaters tend to pay for themselves. A tonne of firewood typically costs between $300 and $400 and can last around three months of moderate use. For many households – especially in colder parts of Victoria, Tasmania, and regional NSW – that works out significantly cheaper per winter than gas ducted heating or portable electric heaters. The exact savings depend on your home, your climate, and how much you use the heater, but the running cost advantage is real and it compounds year after year.
A wood heater also adds genuine value at resale. Buyers in cooler regions actively look for homes with solid heating already installed – it’s one less thing to organise after moving in.

Frequently asked questions
Do I need a permit to install a wood heater?
It depends on where you live. In Victoria, you generally don’t need a building permit, but installation must be carried out by a licensed plumber. In NSW, you’ll likely need to submit a planning application through the NSW Planning Portal before work begins. Other states and councils have their own rules, so always check with your local authority before committing.
How long does a wood heater installation take?
A straightforward freestanding installation in a single-storey home typically takes one day. Inbuilt installations that need cavity construction, structural work, or finishing by additional trades can take two to three days, sometimes longer if plastering or painting is involved.
Can I install a wood heater in a home that has never had one?
Yes. You don’t need an existing chimney or fireplace. The installer will cut a penetration through your ceiling and roof for the flue, fit a hearth pad if your floor isn’t already non-combustible, and install heat shields where needed. A site assessment will confirm whether your home is suitable and identify any complications.
Is it cheaper to install a freestanding or inbuilt wood heater?
Freestanding is almost always cheaper to install. The heater sits on a hearth pad and the flue runs straight up – minimal structural work. Inbuilt heaters require a cavity to be built into the wall, which adds framing, fireproofing, and often plastering. Expect inbuilt installation to cost $1,000 to $2,000 more than a comparable freestanding setup.
Do I need to tell my insurance company about a wood heater?
Yes. You should notify your home insurance provider before or immediately after installation. A compliance certificate from your installer confirms the job meets Australian Standard AS/NZS 2918 – your insurer will want to see this. Failing to notify them could affect your cover.
