In August 2015 revised Australian Standards AS/NZS 4013:2014 and AS/NZS 4012:2014, relating to emission limits, and to power and efficiency ratings for wood heaters were released. Prior to the release of the revised Standards, the emission limit under the Australian Standard (AS/NZS 4013:1999) for any new wood heater sold was 4 grams of particles for every kilogram of wood burned (i.e. g/kg). The revised Standard for wood heater emissions (AS/NZS 4013:2014) tightens the emission limit for heaters (the limit measured in a laboratory test specified in the Standard), in two stages. A limit of 2.5 grams per kilogram came into effect on 8 August 2015, and a limit of 1.5 grams per kilogram will apply from 8 August 2019. This phase-in allows manufacturers time to rework heater designs where necessary, and allows retailers time to clear old stock.
All wood heaters should be installed in accordance with the requirements of AS/NZS 2918:2001 and the Building Code of Australia.
The Environmental Management and Pollution Control (Smoke) Regulations 2019 took effect on 26 June 2019, replacing the expired Environmental Management and Pollution Control (Distributed Atmospheric Emissions) Regulations 2018.
The Smoke Regulations require domestic wood heaters manufactured, imported for sale or sold in Tasmania to meet Australian Standard AS/NZS 4012:2014 for power output and efficiency and Australian Standard AS/NZS 4013:2014 for flue gas emissions.
Before having your wood heater installed
- Check with your relevant permit authority as notification is required under Building Regulations.
- Make sure your heater and any fittings are installed according to the manufacturer's instructions by a person licensed for solid fuel heater installation.
- Ensure the installation is carried out according to relevant Australian Standards. A catalytic converter installed in the heater can further reduce emissions.
