What Affects Wood Heater Installation Cost?
- Type of heater installation: The biggest pricing driver is whether you are replacing a heater on an existing flue, installing a freestanding wood heater, or choosing an inbuilt wood fireplace. Single-storey supply and install rates are AUD 2,800, AUD 4,200, and AUD 7,500 per heater respectively.
- Flue height and storeys: Wood heater flue installation costs rise when the flue needs to run through a double-storey home. The calculator applies a multiplier of 1.3 compared with the single-storey base rate.
- Chimney type or site access: Jobs involving a masonry chimney or tight access are more complex and use a 1.45 multiplier. This can significantly increase the total compared with a standard single-storey flue installation.
- Number of heaters: This calculator is priced per heater, so the total increases with each additional unit. Typical examples use 1 heater, but larger homes or multi-room setups will scale directly by the per-heater rate and the selected multiplier.
Wood Heater Installation Cost - Frequently Asked Questions
For 1 heater with a standard single-storey flue, the midpoint rates are AUD 2,800 to replace a heater on an existing flue, AUD 4,200 for a freestanding wood heater installation, and AUD 7,500 for an inbuilt wood fireplace. The displayed estimate range is usually shown at plus or minus 20% around those figures. A minimum job charge of AUD 2,200 applies if the calculation falls below that amount.
An inbuilt wood burning fireplace installation cost starts from a midpoint of AUD 7,500 per heater for a typical single-storey flue setup. With the calculator's displayed range, that would usually present around AUD 6,000 to AUD 9,000. If the job involves a double-storey flue or masonry chimney/tight access, the total increases using the 1.3 or 1.45 multiplier.
Freestanding wood heater installation is priced at AUD 4,200 per heater for a standard single-storey flue. With the calculator's plus or minus 20% display, that typically shows as about AUD 3,360 to AUD 5,040. More complex flue runs or access conditions increase the price from that base.
For a double-storey flue, the calculator applies a 1.3 multiplier to the base installation rate. That means a freestanding wood heater goes from AUD 4,200 to AUD 5,460, a heater replacement on an existing flue goes from AUD 2,800 to AUD 3,640, and an inbuilt wood fireplace goes from AUD 7,500 to AUD 9,750 per heater. The displayed range is then shown at plus or minus 20% around those amounts.
The main cost factors are the installation type, the flue configuration, and whether the job has masonry chimney requirements or tight access. For example, a single-storey inbuilt wood fireplace is AUD 7,500 per heater, while the same job with a masonry chimney or tight access uses a 1.45 multiplier, bringing the midpoint to AUD 10,875. Those variables generally have a bigger impact than the heater count on a typical 1-heater job.
If you are swapping a freestanding unit onto a sound existing flue with no new roof penetration, the replacement price is AUD 2,800 per heater at the single-storey rate. The displayed estimate range would typically be around AUD 2,240 to AUD 3,360. This is usually the cheapest tier in the calculator because the existing flue reduces labour and materials.
